ALL YOU NEED TO KNOW ABOUT MALE HEALTH...
| The human urogenital system is a combination of two systems of the body: the reproductive system and the urinary system. Generally, the reproductive system is necessary for procreation, and the urinary system is responsible for the formation and elimination of urine. Both parts of the urogenital system share common original tissue from the fetal stage. They also have common ducts that allow the excretion of urine and the ejaculation of sperm, although at different times. The urinary system of both males and females are almost identical. It usually is composed of two kidneys, two ureters, one bladder, and one urethra. The kidneys are the main organs of the urogenital system. When blood passes through the kidneys, harmful substances and waste products typically are filtered out and removed from the body in the form of urine. Kidneys usually help maintain a balance of water and salt in the body, while also producing the hormone erythropoietin, which promotes red blood cell production. Each kidney usually is connected to a ureter – which is about 10 to 12 inches long (about 25.4 cm to 30.5 cm) – that allows passage of urine to the bladder. The bladder temporarily stores urine before excreting it out through the urethra in a process known as urination. | |
| A female urethra typically is shorter that a male urethra, and is used only for urination. On the other hand, the male urethra usually is longer and acts as a passage way for urine, prostate secretions, and sperm. The reproductive system of males and females in the urogenital system varies considerably. Male reproductive system components include testes, seminal vesicles, seminal ducts, prostate, and penis. The parts present in the female reproductive system include ovaries, fallopian tubes, uterus, vagina, and clitoris. Male testes are responsible for the formation of sperm and for the production of male hormones, or androgens. Each testicle is enclosed in the scrotum for protection and regulation of heat. Secretions from the prostate gland and the seminal vesicles make up semen which enhances the passage of sperm through the urethra. Semen is alkaline in nature in order to neutralize the acidity of the vagina, thereby prolonging the life of the sperm once ejaculation takes place during intercourse. It is important to keep some simple higienic rules to avoid the usual problems in the penis. |

After a few years in the market, and their emergence has led to
prejudice and false beliefs, which were eliminated. In the early stages
of research and clinical use, has proven highly effective with few side
effects. Today, sildenafil citrate, known as Viagra has become one of
the most used drugs, and that in recent years, its worldwide sales rose
a dizzying manner. Commotion by the appearance of the famous pill, which was originally developed Viagra (sildenafil citrate) as a treatment for heart problems. However, later studies showed that this pill also increased blood flow to the penis, so quickly was considered effective for the treatment of erectile dysfunction (impotence). Viagra was approved by the Agency of food and medicine in the United States in 1998. Since then it has become popular, and today is available in over 90 countries. Has proven effective in treating impotence. |  |
 | This may be caused by aging, vascular disease, diabetes,
prostate operations, spinal cord injuries and even have psychological
origins. Sildenafil, which is marketed under the name Viagra, favors
the increase of blood supply to the penis, causing erection. But this
drug only works when the man is sexually aroused. Despite the
upheaval that brought the advent of Viagra, in the medical, media and
popular at first sales were not expected and the acceptance by the
patients was with some trepidation and reluctance. However, sildenafil
is a drug, both in the stages of research and in clinical use, has
proven highly effective with few side effects. It is important to note that this is a drug for a specific medical and psychological condition: erectile dysfunction. Although there are people who use it to improve sexual performance, and is even being considered for use in women. |

MALE REPRODUCTIVE SYSTEM
It is the set of bodies to produce and deposit sperm in the female reproductive tract in the act of intercourse. The bodies are the testes produce sperm, contained within the scrotum, which is located outside skin of the abdominal cavity. Sperm are formed within the seminiferous tubules of testes and results in a very long winding tube called epididymis located on the dorsal region of the testis.
The epididymis is continuous with a duct wall thicker and contractile called a duct or vas deferens entering the abdomen and passes behind the bladder to empty finally into the urethra through the last part called ejaculatory duct. Attached to the vas deferens to the seminal vesicles are located which are 2-producing glands of the liquid that accompanies the set forming sperm in semen. Every living being as an individual fulfills a life cycle with a beginning and an end: it is born, grows, reproduces and dies.
But while the life of the individual has completed, the reproduction ensures, through the offspring, the perpetuation through time.
In all species occurs that the descendants of the parents have inherited characteristics of the chromosomes. Reproduction is the biological process that allows living things originate new beings to conserve the species. In humans, reproduction meets all the characteristics of the reproduction of other mammals. The man and woman are able to reproduce from the time of sexual maturation, about 13 to 14 years. Since that time, humans are permanently unable to procreate because the species does not exist in a period of heat, suitable for reproduction, as in other species.
"MORPHOLOGY AND PERFORMANCE OF THE MALE REPRODUCTIVE SYSTEM
The male sexual system consists of the external genitals are the penis and scrotum and internal genitalia: the testes, the seminiferous tubules, the epididymis, the vas deferens, the seminal vesicles, prostate gland, ejaculatory ducts, glands Cowper and urethra. Then we will analyze the morphology and function of each of these components: "External Genitalia The penis is the organ of copulation, their function is to carry sperm to the female genitalia during intercourse. Organ of urination is also, since it has the final portion of the urethra. Born in the anterior perineum. Attached to the branches isquiopubian, goes to the symphysis where it becomes free, is surrounded by a skin envelope and bends freely hanging down in front of the pubis. It can be seen on the penis two portions: a posterior or perineum, glans, and a previous or free. The earlier part of flaccidity or resting state is soft, cylindrical and hangs vertically. Grows erect, becomes hard and becomes a triangular prism, reaching a length of 15-16 cm. The glans is covered by a fold or skin called the foreskin. It's like a hood, and can retreat back to expose the glans, except in newborns. Shortly after birth, some children, this skin are removed in a process called circumcision.
The scrotum or scrotal sac is the skin surface that covers the testicles. The scrotum is divided into two halves, corresponding to each testicle and surrounding structures. It is divided by a median raphe. The main function of the scrotum is to maintain and control the natural temperature of the testes. On occasions, especially when it's cold, the scrotum muscle fibers make the entire sac to contract or shrink, the testicles closer to the body to keep them warm. In other conditions, hot weather, or are in complete relaxation, the scrotum becomes loose and soft, with smooth surface. Then the testes hang away from the body more, so stay fresher. Typically, the left scrotum down more than the right. It's a sensitive skin, thin and dark, marked by transverse folds, well watered and rich in nerve endings, which give it its characteristic sensitivity.
"Internal Genitalia, The testes, or male gonads are two bodies symmetrical situation, hang in the scrotum below the penis and have a dual function, produce sperm and hormones. The shape of the testis is ovoid, with an average size of about 40 to 50 mm. long, 2.5 mm. thick and 30 mm. wide. It weighs around 20 grams. are white-blue, due to the albuginea layer that surrounds them, and very hard consistency. The albuginea is a capsule of connective tissue and white inextensible surrounding the testicle. They are in the groin and leaving the abdomen through the inguinal canal to below the penis and in front of the perineum. After puberty, sperm are produced in each testicle. The development of an individual sperm takes about ten weeks. Each month they produce billions of sperm, with a slight decline in recent years. If no sperm are ejaculated simply destroy themselves and are absorbed by the tissue of the testis. The sperm has three parts: a head, neck and tail. The head has 23 pairs of chromosomes, which carry the human contribution to the child's genetic inheritance. The other half is contributed by the female egg or egg, which also contains 23 chromosomes.
The neck and body of the spermatozoon contain material that can be converted into energy, so that sperm can move by itself after being ejaculated by the man. The tail of the spermatozoon moves forward and backward, like a tadpole to allow the sperm to progress through the vagina, the uterus rises and reaches the fallopian tubes. The sperm moves about 14 or 16 cm. per hour. The production process of sperm is called spermatogenesis, and usually within 60 to 72 days while mature sperm. Testosterone is the primary male hormone around a group collectively called androgens. These are mainly produced in the testes, but also produced very small amounts in the adrenal glands. The testes and adrenal glands of man also produce a very small amount of estrogen, the female sex hormone. Testosterone production is stimulated and influenced by a complex signaling system that involves the pituitary gland and hypothalamus. The growth and development of the penis, testicles and scrotum, and the appearance of pubic hair, beard growth and other secondary sexual characteristics are the result of high testosterone levels that occur during puberty and after it. Testosterone also influences sexual drive and interest, so that a low testosterone level causes a low libido or sex drive.
We can say that the seminiferous tubules of the testes are housed in its interior. They consist of two cell types: one Sertoli cells and other cells in the germinal epithelium. Between the seminiferous tubules there is a loose connective tissue within which are the interstitial or Leydig cells, which are responsible for the endocrine function of sex hormone secretion. Seminiferous ducts ducts converge in short, narrow, straight-called straight pipes. These, in turn, end up on a network of canaliculi cubic fitted with a single layer epithelium, located in the rete testis. The rete testis is attached to the epididymis through the efferent ducts, which are wrapped on itself becoming conical with the apex away from the testicle. The epididymis of posteriosuperior located in the testicle, is divided into three parts: head, body and tail, respectively formed by the efferent ductules, the sinuisodales duct and the duct length. While the epididymis is about 5 cm. long, the tube that is formed, which is very inward-looking, can reach up to 6 m. It is surrounded by connective tissue and covered by an envelope similar to the testicle called the epididymis albuginea. The remaining sperm in the epididymis until they are destroyed and are absorbed by the surrounding tissue or until they are ejaculated.
The epididymis the vas deferens followed, culminating in the ejaculatory duct. Each testicle is attached to each testicle in a narrow tube called the vas deferens. Each glass is about 40 cm. long and 2 mm. in diameter while its light has a diameter of about 0.5 mm. mainly due to the thick muscle layer that surrounds him. It is cylindrical in shape and follows a very complicated journey, then running from the tail of the epididymis, running parallel to it on its inner side and the top of the testicle, up to a point in the anterior portion of the latter, in the which, thanks to a kink up into the external orifice of the inguinal canal. Walk the canal, reaches the pelvis and ends at the ejaculatory duct, formed by the confluence of the vas deferens and seminal vesicle.
When they have gone for a glass, the sperm are mixed with fluids from the seminal vesicles and prostate gland, forming a new substance, semen or sperm, is what the man ejaculates. Located on each side and just above the prostate gland are the seminal vesicles. They are located in close connection with the spermatic ducts, to the extent that some authors are part of them, the seminal vesicles are few receptacles that can store sperm in the inter-ejaculation periods, but they are also endowed with the capacity to segregate a portion of seminal fluid. They bind to the distal end of the vas deferens at the point where they are transformed into the ejaculatory ducts.
The seminal vesicles are configured as tortuous ducts fall back on themselves, placed between bladder and rectum, with obliquely outward, backward and upward. Pear-shaped, with a progressive increase in size since its origin in the vas deferens to its end in blind pouch. Measure each 5-6 cm., And along the same are distinguished neck, body, and a background. The prostate gland is a complex tubuloalveolar including muscle mass developed in the initial portion of the male urethra below the bladder. Its size and shape approximates that of a walnut. You are at a crossroads urogenital, as elements in groups its tone at the beginning of the urethra ends at the point where the ejaculatory ducts. It is also related to the bladder sphincter. Body can be distinguished in this top layer, an apex, anterior, a posterior and two lateral sides. The prostate volume varies according to age. Little developed in childhood, rises sharply during puberty, reaching the twenty or twenty-four full development. In the adult is about 25-30 mm. in height by 40 mm. wide and 25 mm. thick. It weighs 20-25 gr. Concerning the internal constitution of the prostate gland are distinguished 3 rings, which are called periurethral environment and peripherals.
After puberty, the prostate secretes a substance which, like the seminal vesicle fluid, serves as nourishment for the sperm and increase their mobility. The prostatic fluid is approximately 39% of the semen, the seminal vesicles by 60% and sperm only about 1%.
Immediately after the point where it empties into the seminal vesicle the vas deferens, the tube, which is now common to the testis and seminal vesicle called the ejaculatory duct. It pierces the upper surface of the prostate gland. Continue on the substance of the gland and empties into the urethra at the level of the veru montanum. It measures about 2.5 cm long. During sex, semen collects in these two canals, and when sexual arousal reaches its highest point, a spinal reflex causes rhythmic contractions throughout the area and propels the semen out of the urethra in gushes. This process is called ejaculation. Cowper's glands are also called bulb-urethral glands or Mery-Cowper. Tubulo-alveolar glands are the size of a pea, that lie at number two on both sides of the posterior extremity of the bulb of the urethra. More specifically, are located in the thickness of the deep transverse perineal muscle, or the posterior part of the urethra sphincter.
From each gland Cowper's excretory duct emerges from 30 to 40 mm. long, which is directed obliquely forward and inward to enter the bulb. From there the two parallel paths in the urethral wall thickness, to open in the urethral bulb by its inferior wall.
During sexual arousal but before ejaculation, these tiny glands secrete a small amount of fluid that exits the urethra and urinary meatus appears at the tip of the penis and around it. This small amount of fluid containing sperm that are already out of the ejaculatory ducts, sufficient to produce pregnancy if ejaculation is not produced any yet. In the male urethra is divided into three regions: the prostatic urethra, membranous urethra and the cavernous urethra. The first one has a length of about 3 cm. and she lead the prostate and the vas deferens pairs. The membranous urethra is shorter, with a length of 2.5 cm., And it is the external sphincter. The longest section is for cavernous urethra, which is 15 cm. long and ends at the urethral meatus. The spontaneous passage of urine from the bladder to the urethra not caused by the existence of two sphincters, the internal urethral sphincter composed of smooth muscle fibers arranged in bundles spiral, longitudinal and circular, which together are called the detrusor muscle bladder, and these consisted of smooth muscle fibers are sympathetic and parasympathetic innervation, and external urethral sphincter, which consists of skeletal muscle is controlled voluntarily.
The urethra has two functions: to allow urine to exit from the bladder to the outside of the penis and allow the semen to be ejaculated.
"Sperm function As we have seen the semen, containing sperm is ejaculated and if this happens inside the vagina of a woman in her fertile period is possible that one of the sperm head crossed with the outermost layer of the egg, penetrating into the center of same. When this happens no other sperm can enter the same egg. Fertilization takes place, usually in the fallopian tube and in the 24 hours following ovulation, therefore, women have limited time to get pregnant in each menstrual cycle. Sperm remain alive in the vagina, uterus and fallopian tubes for several days, which can penetrate the egg but the egg loses its ability to be fertilized between 24 and 36 hours. When sperm has penetrated the egg, fertilization has occurred and, at that time, there is already a single cell called a zygote.
MORPHOLOGY AND PERFORMANCE OF FEMALE REPRODUCTIVE
The female reproductive system allows sexually healthy women produce mature eggs, transporting them to be fertilized and fed once fertilized. The description of female sexual system is divided into three parts:
1 - The external genitalia or vulva is the name designating the whole of the genitals that may be.
The vulva consists of the following parts: the labia majora, labia that are large and external pubic mound, situated above the vulva, is a mound of soft hair covered in puberty labia minora, which found within the major, the clitoris, located at the junction of the labia minora and the vestibule, which is an almond-shaped area located within the labia minora, which shows the urinary tract and vaginal opening.
2 - The internal genitalia "It's the woman's reproductive system and has these parts: the hymen, Bartholin glands, the urethra, vagina, cervix, uterus or womb, fallopian tubes and ovaries, where eggs are stored.
3 - The breast-Who, despite not being genitals, have a considerable sexual meaning.
Then analyze each of the parties set forth:
The labia majora are two major skin folds that limit the pudendal cleft, which lead urethra and vagina. They measure about 8-9 cm. long and 2 cm. high with a base of about 2cm.
The mound is an accumulation of subcutaneous fat above the pubic bone and is covered with hair in a triangular area whose base has a slight depression that marks the boundary with the hypogastric region. At the apex of the triangle coincides with the union of the labia. The labia minora are located inside the labia majora, follow the same direction from the front, but just by docking them at the junction of the middle and lower thirds and help to form the fork in front of the posterior commissure of lips higher.
The clitoris is located where the inner lips are joined under. It has a unique function: to give pleasure to its owner. It has nothing to do with having children. The many nerve endings that are in the clitoris and surrounding areas make it very sensitive to contact, both direct and indirect. It consists of a head or glans call round area and a long part called the shaft or body, which normally is covered by the fabric of the inner lips. Its size can vary usually between half a centimeter and a centimeter, but when stimulated is filled with blood that flows in and increases in size and can double its diameter. When continuous stimulation and orgasm approaches, the clitoris retracts and hides under the cap, turning to leave when the stimulation stops. The orgasm will produce a release of the accumulated blood in the clitoris.
The lobby has two main parts: the opening of the urethra and vagina. The opening of the urethra below the clitoris and above the vaginal opening. The vaginal opening is a big hole and can best be seen when the lips are separated. The hymen is inside the vagina, just above its opening, and is a thin piece of tissue that partially block the road inland. It has no known biological function, and with different women varies in size and shape. Do not cover the entire vaginal opening and that there should be a hole that allows the exit of menstrual flow or period. When broken the hymen, either during intercourse or at another time may appear some pain and bleeding. Both are quite normal and will subside soon. On each side of the labia minora are the Bartholin glands, which have their outlets near the vaginal opening, producing a small amount of fluid when a woman is sexually aroused. Previously it was thought that this small amount of fluid intervened significantly in vaginal lubrication, but medical studies have shown later that vaginal lubrication comes from much further up the vagina and is yet to discover which is the function of these glands.
The urethra is the final segment of the urinary tract. The urethra of women, very different from that of men, is about 4 cm. and is lined by squamous epithelium. The spontaneous passage of urine from the bladder to the urethra is caused by the existence of two sphincters: the internal urethral sphincter composed of smooth muscle fibers arranged in bundles spiral, longitudinal and circular, which together are known as bladder detrusor muscle , and these consisted of smooth muscle fibers are sympathetic and parasympathetic innervation, and external urethral sphincter, which consists of skeletal muscle is controlled voluntarily.
The vagina is a cylindrical, musculomembranous, flattened from front to back, which goes from the vulva to the cervix, and possesses a great capacity for expansion and contraction. Its length varies around 8 cm., Which varies by individual differences, sex life or parity. the width is 2.5 cm., being higher in the upper extremity and lower in the bottom. Outside, the vagina is related to other pelvic organs. Ahead is the bladder and vesico-vaginal septum, and further down the urethra, which is intimately linked. Behind is the pouch of Douglas at the top and is situated behind the rectum. Laterally, at the top is the base of the broad ligament and through it reach the blood vessels supplying the vagina, finding large venous plexus. During sexual arousal the vagina responds almost immediately to stimulation, lubricated by small drops of fluid that appear on their walls. The cervix has a length of about 3 cm. and a thickness of 2.5 cm. Its shape is cylindrical and the vagina is attached circumferentially around though in an oblique plane higher behind than in front. This allows to divide the neck into two parts, the supravaginal and intravaginal. Intravaginal portion is called the cervix. The cervical canal is fusiform, with two faces, front and back flat support one over another. In them there are some creases on palm-leaf form so-called "tree of life".
Has the ability to expand and contract to allow the passage of the fetus at delivery. Also passes through the cervix into her menstrual flow path out through the vagina. The sperm after being deposited in the vagina to the cervix into the uterus and fallopian tubes. The cervix secretes a fluid called cervical mucus during the menstrual cycle the mucus changes in appearance, those who practice natural family planning method is used as an indicator of safe or unsafe days for intercourse. It's called cervical mucus method or Billings. The uterus, known familiarly as the matrix, is a hollow organ located in the middle of the pelvic excavation between the bladder and rectum. Its cavity communicates laterally with the tubes and, below, with the vagina, the organ that continues outward.
In the uterus there are two distinct parts: body and neck, both united by a short circular structure or isthmus. Body and neck are usually an obtuse angle open toward the front, it is said that uterus is ante. The anterior part of the uterus or uterine body, is the largest section of the organ. The shape resembles a pear, whose widest part is located toward the top.
There is great difference in size and weight between the wombs of women who have not had children, and those that do. For example, the weight in nulliparous women (without children) ranges between 45-50 deg., Whereas in multiparas (with several children) is of 60-65 gr. The uterine body cavity is relatively small, flattened, with anterior and posterior applied against each other.
Uterine or fallopian tubes, also called oviducts, two bodies are hollow, cylindrical, long and narrow, arising from the higher bodies of the uterus and ovaries extend into the lining part. The set of tubes and ovaries is generally known as uterine appendages.
The tubes are between 10 and 14 cm. length and diameter will widen from the inside out, ranging from 3 to 8 mm. All tube has great capacity for stretching. The walls of the fallopian tubes are lined with structures similar to the hair, called cilia, that contract slightly along the tubes and help the egg on its way to the uterus. It is important to note also that any sperm that reaches the fallopian tubes must move or swim against the tide. As said the tubes are a hollow organ, and it lets you establish a communication between the uterine cavity and abdominal cavity near the ovary. The ovaries, located symmetrically on the posterior face of the broad ligament near the side wall of the pelvic excavation, are the most important organs of the female genital tract, both for its generating function as endocrine function. Ovoid-shaped, somewhat flattened from without inward, almost vertical shaft in nulliparous, and a size of approximately 35 mm. long by 20 wide by 10 thick, with one 5-gram weight. The color is pinkish-white, and hard consistency. But along life changes in appearance, also depending on the deliveries that have had women. At birth the girl the ovary is relatively large at maturity its surface becomes rough and irregular, and after menopause is stunted, but could be in the old woman as small as a bean.
A woman is born approximately 200,000 eggs in each ovary ( "ovum" is Latin for "egg", "egg" would be his diminutive). During the reproductive years of women released between 300 and 500 of these eggs. Each egg is in a follicle, a cavity in which the egg can remain immature. When the mature egg leaves the cavity and is expelled from the ovary. Women's breasts are organs related to sexuality and reproduction closely. There are three important aspects in relation to the breasts: they often provide erotic pleasure, play an important role in the image itself has a wife and a woman can feed a child with them. Men's breasts can give pleasure but have little influence on the self-image. The erection of the nipples is a normal reaction to stimulation. Until menopause, if she has not breastfed, stimulating your breasts will also grow in size, to fill with blood in his veins. Men's breasts do not increase in size by the stimulation, but more than 50% of cases show a nipple erection. Also, being naked or having cold can cause the nipples to harden, especially in women. Each nipple has an aura about him, which is a dark in color and size vary for each woman. It is normal to have little bumps in the aura: they are oil producing glands that secrete a lubricant to facilitate breastfeeding. During pregnancy, the areola darkens and remains so until after delivery.
Within each heart there are 15 to 25 small bags of milk producers. The milk they produce passes through ducts to the nipple, and list the child to suck. Regardless of the size of the breast, mammary glands are the same size in every woman and produce about the same amount of milk.
"PHYSIOLOGY OF FEMALE SEXUAL APPLIANCE
The ovaries play a central role in female reproduction, since they are responsible for two closely related functions: the production of eggs and sex hormones. These two functions are regulated by two centers of the brain: the hypothalamus and anterior pituitary. In turn, the main place where ovarian hormones act is the uterus and ovulation may continue until the implantation of the fertilized egg into the uterine cavity. Both ovulation and hormone production by the ovaries is often repeated rigorous: the ovarian cycle. This cycle is based on changes that occur during the development of female reproductive cells, the resulting eggs.
Each month in the life of a woman while this is fertile, the pituitary gland in the brain secretes a hormone called follicle stimulating hormone (FSH), which stimulates usually one of the ovaries to develop a follicle. The eggs are stored within the follicles and mature there. When sufficient amounts of circulating FSH, and luteinizing hormone called the follicle bursts and releases the egg into the fallopian tube, a process called ovulation. The egg passes down the tube to the uterus and either implanted in the uterine wall and fertilized egg (pregnancy), or is expelled along with the uterine lining and unfertilized egg (menstruation). The follicle that housed the mature egg into the corpus luteum, which secretes large amounts of progesterone during the second half of the month. He grows old and dies.

Priapism is a persistent abnormal erection of the penis, usually without sexual desire, and is accompanied by pain and tenderness. A lack of detumescence is referred to as a prolonged erection if the duration of the rigidity is less than 4 to 6 hours and priapism if the erection lasts longer than 4 to 6 hours. If the erection lasts longer than 6 to 8 hours, it is often associated with pain. Priapism may occur from too much blood flow into the penis (high flow), or it may be a result of too little bood flow out of the penis (low flow). High-flow priapism may occur after there has been an injury to the penis that causes damage to an artery that results iunregulated blood flow into the penis. Because there is an increase in arterial blood (which carries oxygen) into the penis, high-flow priapism does not cause pain. In high-flow priapism, there is venous drainage out of the penis, so the erection does not tend to be as rigid as in a full erection. Low-flow priapism occurs more in men with sickle cell disease and trait - a condition in which the red blood cells take on an abnormal (sickle) shape in response to decreased unregulated blood flow into the penis. Because there is an increase in arterial blood (which carries oxygen) into the penis, high-flow priapism does not cause pain. In high-flow priapism, there is venous drainage out of the penis, so the erection does not tend to be as rigid as in a full erection. Low-flow priapism occurs more in men with sickle cell disease and trait - a condition in which the red blood cells take on an abnormal (sickle) shape in response to decreased oxygenation, dehydration, and acidosis - and cancers of the blood, such as leukemia. It may also occur with injection therapy for erectile dysfunction and with certain psychiatric medications, such as trazodone. Because the problem consists of a problem with drainage of blood from the penis, which has little oxygen in it, this form of priapism is associated with pain and full rigidity.cted during intercourse, with a man withdrawing his penis from his partner just before ejaculation.
