ANATOMY AND PHYSIOLOGY OF FEMALE GENITALIA INCLUDING THE SKENE GLANDS, EJACULATION AND G-SPOT

During sexual intercourse usually there is erotic wetness by the woman and it may be due to either ejaculation or due to urinary incontinence. It is very difficult even for a woman to distinguish between the two. A small proportion of women many times relate intercourse related incontinence to particular moments of intercourse due to lesser awareness about female ejaculation.

Urinary incontinence and ejaculation.

Usually women discharge fluid during their sexual intercourse through their urethra and this can be confused with either urinary incontinence or female ejaculation. Many women have confusion regarding what they are experiencing.

It has been debated whether women wrongly relate their intercourse related incontinence to their particular moments of sexual intercourse due to unawareness of female ejaculation. Only a small proportion of women really have qualms about this while most women seems to do know what they are experiencing during intercourse. This has been confirmed by Cartwright in his recent study, reporting that if women refer to female ejaculation with no subjective suspicions of other causes of urinary incontinence, then it has to be considered as true and further scrutiny is not required.

Women usually know best about themselves and they by nature know whether they are experiencing urinary incontinence or female ejaculation by instinct. Medical examination, diagnosis, and treatment are required only if she suspects that she is experiencing urinary incontinence. If a woman categorically says what she is experiencing is female ejaculation then she has to be trusted and no medical examination of treatment is warranted.

There was some doubt whether the fluid discharging through the urethra during intercourse is a medical condition or it is just a normal sexual phenomenon. Another study says nearly 43% of women have enjoyed ejaculation during masturbation while 46% have not. The interpretation of this data is that female ejaculation cannot be a totally unusual experience. Medical research till now has ruled out medical condition associated with female ejaculation.

This medical research could be a good start for those who are looking for study materials on urinary incontinence and female ejaculation. In my layman’s opinion on urology of women, female sexual anatomy and surgical treatments, a medical condition of the genitourinary system of women cannot be underrated. If what you are experiencing urinary incontinence only during coitus or masturbation, then I would advice you to enjoy the feel and towel yourself well. In my opinion, a medical advice over this is usually not required.

Body fluids of women.

Knowledge about female body fluids in general is essential before addressing the issue of female ejaculation. Throughout time across the world most of the societies consider viewing of female body secretions with great contempt. If any women involves in any activity that makes her body fluids visible to others, then she will be considered less feminine and unwanted. Many societies even believed menstruating women have the potential to cause failing of crops and death or loss of livestock. This attitude of the society over the body fluids of women created a heavy barrier between sexual pleasure and women.

Women are desired to present a dry and immaculate appearance despite whatever activities they engage in. During earlier times mothers instructed daughters not to involve in playful activities or sports as boys and men would chance to see them perspiring and unkempt and this was considered unfeminine. Even today, deodorant and antiperspirant product producing companies advertise their products with the caption “Don’t let them catch you sweating”. They even advertise that they produce a unique stronger version of deodorants and antiperspirants for women. Tampoon and sanitary napkin producing companies also advertise their products as a gadget to hide the menstruation rather than absorb the menses. Women would have their ears cut off rather than been accidentally seen menstruating in the public. There is no big secret in women menstruating. Everyone knows this. Yet it is the attitude of the media and the society that has made people discuss it as the ‘birds and the bees’ way rather than something normal and usual.

Men with beady sweats dribbling all over the body are frequently visualized as sexual and virile. Usually men are considered manlier if they produce more semen. They engage in competitions who can ejaculate furthest. Men do write their names in snow by passing urine on it for the whole world to see. The wetness produced by men by way of ejaculation is actually messier, but it is always considered as normal and many times he is questioned only if he doesn’t make that mess. In adult movies anyone can see men ejaculating over the face, mouth or over any part of the body of the partner and no one considers it a mess. If a woman makes a wet scene during sexual intercourse, then it is always considered as dirty. This double standard is created by the male dominated society. If man is allowed to ejaculate all over the body of women, women too have the right to do it.

The sexuality of women is always considered secondary to men. Many women totally avoid sex, as they produce lot of uncontrolled fluid discharge from the vagina, for fear of deemed as less feminine by the sexual partner. These women, when highly aroused for a long period of time, produce copious amount of vaginal fluids. It will be a very tough time for them to enjoy sex if they were made to worry about the vaginal wetness all the time during intercourse.

If a woman has to enjoy sex and ejaculation, she must first consider her body fluids as a part of her body and normal. If even she disdains her own body fluids who will not? She should accept all her body fluids in their actual color, odor, nature, quantity and the orifice through which it comes. Let it be vaginal secretions, urine, menses or ejaculate, saliva, tear or sweat. They all are part of a woman’s body and their lives and there is not big secret in these to hide them. They are not bad or harmful to anybody. A woman has to freely enjoy and let go the urge to urinate or ejaculate, merging with the feel for her to fully enjoy the sexual experience and have ground-shaking orgasms. Women should let themselves be wet and as messy as men during coitus. Let men understand and accept women as they are created.

There are so many debates going on centering over discharge of fluids from the urethra of women during intercourse. Some believe if the women discharge fluids from her urethra then that could be a medical condition. What is the necessity for such a discussion at all? How does it matter if fluid comes out of her vagina or urethra as long as she remains normal and has enjoyable sex life? Is it is problem for us in the first place? If women eject fluid from bladder, let them do it. Who gave us the authority to judge the rights and wrongs of women’s ejaculation?

The Prostate gland of women.

Image showing the Skene gland’s duct openings.

In the embryonic stage both sexes have phenotypically similar genital organs. They appear like that of a female. The male fetus undergoes changes and the clitoral part of the embryo develops into penis under the influence of testosterone, which is produced by the effect of ‘Y’ chromosome. The testosterone also effects the formation of testis inside the abdomen and then it descends down into the two labia like structures (vaginal lips of women) of the early embryo forming the scrotal sac inside which testes are placed. All these happen around the 8th week of gestation. Only from then sexual difference starts in the embryo. Thus the female structure is the base of all humans which is transformed into the male one by the influence of male hormones. The male prostate gland is formed from the urogenital sinus and this sinus is present in the female embryo too. This in later development grows into the female prostate.

The first person to understand this and describe it as a ‘female prostate’ is a Western medical researcher called Reinier De Graaf (1641-1673) in 1672. He says that the female prostate is a collection of glands and ducts around the female urethra. He also described that these glands produced the ‘pitutoserous juice’ which means ‘a thick mucous secretion, pale yellow and transparent secretion produced by the influence of the pituitary gland’. He says this secretion makes women more libidinous by it pungent nature and saltiness. This fluid also lubricates the vagina and associated parts to make the penile thrust less frictional during intercourse. Despite his study and discrete corroborations from many others, western medical community failed to accept the existence of female prostate till 2001. It was only at 2001, the Federative Committee of Anatomical Terminology accepted to use this term in their subsequent edition of Histology Terminology.

The ‘female prostate’ was a term commonly used by the medical faculty in medical literature prior to the 20th century. Then someone described the female prostate as ‘vestigial’ (not fully functional or developed) and described them as ‘paraurethral or Skene glands’. The female prostate and its components were not given much importance or area of interest or research. The medical faculty just knows its existence and chose to remain silent over its function and importance. The modern medicine thought female prostate as a vestigial organ and therefore did not do any further research in understanding its function. As there are apparently no disease entity associated with the female prostate, the doctor’s office don’t pay much attention to its existence and don’t advise on its usage to the patients. Occasionally diseases of the female prostate like urethral diverticulum or female prostatitis attract the attention of the medical faculty where it is considered as urinary tract infection often and treated likewise.

The male prostate is located around the bulbar urethra while the female prostate lies embedded within the vaginal walls along the length of the female urethra. The female urethra is also a structure which coexists with the female prostate within the vaginal wall. The size of the female prostate is 1.3 inches long, 0.4 inches height and 0.75 inches wide (3.3*1.9*1 cm) and weighs around 0.2 ounces (5.2 grams). It is actually about the size of a woman’s thumb. It is relatively smaller when compared to the male prostate but has retained all the structural components of its male counterpart. Some text books of anatomy describe the male and female prostate as separate discrete organs, but it is unlikely to be true.

The female prostate is shown to be in slightly differing various shapes and sizes but most of the women have their prostate placed near the introitus (vaginal opening), adjacent to the urethral opening. Sometimes the placement of the female prostate can cause the anterior part of the vaginal wall to project into the vaginal passage and it may even cause the urethral opening to project into the vestibule. If it is placed like that then the visualization of the actual gland will be impaired. But stimulation of these projecting structures will arouse great orgasm and ejaculation and this may prove the presence of the organ.

Physiology of the female prostate.

The female prostate has 2 functions. They are the exocrine function and endocrine functions. Exocrine function means it discharges secretions through a duct and exerts functions in the local areas where it is secreted. The endocrine functions mean secretion of hormones by stimulation of neural cells directly into the blood and these hormones exert its functions all over the body. Discussing the exocrine functions first, the female prostate secretes prostate-specific antigen (PSA), prostate-specific acid phosphatase (PSAP or PAP), and fructose, a type of sugar. These are secreted through a duct and discharge into the urethra. The prostatic fluid of female prostate has not been extracted in pure and examined, but till now it has been studied only as one of the component of the female ejaculate. Discussing the endocrine functions, the nerve cells which stimulate and another type of glandular cells which as a response discharge chemicals , put together as one entity called as the neuroendocrine cells. The primary hormone produced by the female prostate is called as serotonin. Serotonin has many neurometabolic functions in our body. As the male prostate is influenced by the androgens and DHEA (dihydroepiandrosterone, a precursor of both estrogens and androgens), the female prostate is thought to be influenced by the estrogens. PAP has been identified from the undergarments of women, which were in continuous contact with the vulva, which means that PAP secretion is continuous right from menarche (onset of puberty). All these medically proven information suggests the actual presence and functioning of the organ beyond any speck of doubt.

Discussion on female ejaculate.

Image showing ejaculating woman.

The fluid that escapes out through the urethra or the vagina during the act of coitus is called as the female ejaculate. In lesser quantities it appears like a mucous fluid, milky white or yellowish with thick consistency and a pungent or musky odor. In larger volumes, the ejaculate appears like clear water and there is no obvious scent. The fluid contains PSA or PAP, which are produced by the female prostate. There are traces of urea and creatinine but in lesser quantities than that is present in the urine. These substances are found in still lesser quantities when they are detected in the urine. The fluid found in ejaculatory fluid and that in urine are not the same in their contents though they share some properties. From orgasm to orgasm the volume and contents of the ejaculatory fluid always changes considerably from the previous ejaculate.

Even the color, smell, consistency, chemical contents, and the taste vary from one ejaculate to the next. Some women say their menstrual cycles affect the type of ejaculatory fluid. This may be because of the alteration of female hormones during menstruation have their effect over the female ejaculate also. What women eat, do have an influence over their ejaculatory fluid like what men eat alters the taste, consistency and contents of semen. The total water content of the body too seems to have some effect over their ejaculatory fluid.

This table below compares the male and female ejaculate contents and also compares with the female urine.

This table suggests that the female ejaculate contains the same contents of that of male ejaculate and the contents of female ejaculate are higher than that of female urine. This proves that the female ejaculate originates from the female prostate as male ejaculate originates from the male prostate.

Physiology of ejaculation in women.

The picture above shows the parts of female genitals. The vulva shown here should be imagined like that of a woman’s lying on her back and with wide spread legs. The vaginal opening (large opening above the lower border of the inner vaginal lips) is the opening below the urethral opening (small opening). The clitoris is the top most nodule like structure at the start of inner vaginal lips. There are lot of parasympathetic nerve endings from S2-S4 nerves, vagal nerve, and the sympathetic (which causes the orgasm) L1-L2 nerves of the nervous system. If these nerve endings were destroyed by over pressure, recurrent infections, or vibration, then the erectile spongy tissue will become atrophied due to decreased blood supply, oxygen, nutrients and androgen hormones. These hormones, blood supply and nerves maintain the nervous sensitivity, the increased blood flow during orgasm and subsequent swelling of glands and tissues, and tissue erection. If they are damaged, then the clitoris will be converted into dead rubber like scar tissue with no sensation.

The stimulation of the vulva and its organs stimulate the nerve endings in that area. These impulses are carried on by these nerve endings and they relay to the brain. On receiving the stimulus and recognizing the nature of the stimulus the brain responds through the nerves that come out of the brain and the spinal cord, that innervate the organs of that area like the skin, soft tissue, muscles, blood vessels and the glands. The erectile tissue becomes taut, muscles contract and relax, blood vessels dilate and flush the organs and the glands secrete fluids. If damage occurs in the dermal, clitoral, vaginal, and cervical nerve endings by abrasion, over-masturbation, over friction, violent sexual activity, and surgery, then the impulse transmission from the nerve endings become erratic and therefore all the positive and normal response is affected. In an attempt to repair the damage the body converts the damaged tissue and cells into scar tissue disrupting the neuroendocrine functions of the organ. Street medications, unwanted drugs and birth control chemicals do produce the similar effect. You should think before you apply these destructive chemicals over the sensitive vulval organs.

Some of the researchers think that the G-spot plays a very important role in ejaculation. The 2007 study by Austrian scientists identified tissue around female urethra which secretes fluid which drains into the urethra. It is therefore very much suspected that the ejaculatory fluid comes from the urethra. But no definite conclusion has been arrived till now whether the fluid comes from the urethra or the vagina. It is very much thought that the Skene’s glands produce the ejaculatory fluid because of the presence of prostate-specific antigen in the fluids. It has been established that the Skene’s glands produce the PSA.

In one study, nearly 54% to 60% of women said they discharge fluid during orgasm. Of these ejaculating women, nearly 6% discharge regularly and said that it was strong, while 13% said they discharged intermittently. Dr.Gary Schubach says that most of the women can ejaculate if they are taught how to ejaculate.

Is ejaculation a rule for all women?

As all women have a prostate gland it is likely that all women are capable of ejaculation whether they are aware of it or not. The ejaculatory fluid may mix up with other sexual juices and surge out during intercourse. The regular moistening of the vulva is effected by the prostatic gland secretions. Whether during sexual arousal or during ordinary times the prostatic overflow will cause seepage of fluid through the urethra. During sexual stimulation the blood flow to the vulva increases and this causes the prostatic gland to engorge and filling it up with its secretions and its subsequent release it through its pores by effective pelvic muscle contraction. The extent sexual arousal many times determines the volume of the ejaculate because the sexual stimulation is directly related to the volume of blood flow to the organ and this in-turn determines the volume of the secretions formed.

The origin of female ejaculate.

Not many medical research articles were available if one wants to study the source of female ejaculate. Among the few studies conducted there were so many discrepancies in the results that a consensus opinion cannot be achieved by analyzing those studies. Some research says that female prostate contributes to the whole of the ejaculate while some other studies mention that most of the female ejaculate is urine and the prostatic content is very little. I personally believe that the ejaculate is varying in nature from women to women. In some women it will be solely from the prostate while in some other it may be both from the bladder and also from the prostate. It is actually impossible to discern where the fluid comes from in every women with each orgasm.

The source of ejaculate.

Only by detailed medical analysis one can ascertain whether the woman’s fluid discharged during intercourse arises from her bladder or from her prostate. No one can clearly establish whether a woman voluntarily or involuntarily discharge fluid from her prostate or from her bladder. Since both the bladder and prostatic fluids are discharged from the same orifice i.e. the urethra, it is very difficult to distinguish the source by visual observation. We cannot distinguish them even by color, smell or taste. As common man we cannot distinguish between them at all.

Ms.Rebecca Chalker, in her famous book ‘The clitoral truth’ says one can distinguish between the female urine and ejaculate by scent. She says acrid scent goes in favor of urine. I believe that if a woman and her partner come to know that the fluid she ejects is urine then it may create a sense of aversion in their minds. I personally believe that we need not deeply analyze what fluid a woman ejaculates during coitus as long as the purpose of coitus is well served. I can understand the curiosity, but we should always understand that we need not learn unwanted information. A superficial idea about female ejaculate is adequate and deeper probing at molecular level is not required for a common person whose aim in sex is pleasure. What is he or she going to do after acquiring such detailed knowledge? Where is he or she going to apply it? It will only lead to arriving at making unwanted judgments.

In his website Dr. Gary Schubach states that his research has shown that the majority of the ejaculatory fluid from the bladder doesn’t appear like normal urine. As a part of his research he emptied a woman’s bladder with a catheter prior to orgasm. The catheter was placed in the urethra attached to a collection bag and the woman was allowed to attain orgasm. He collected the fluid during orgasm and analyzed it. His reports were based on this analysis. Later one problem was identified in his methodology and that was bladder sphincter should remain closed for an ejaculation to occur. If she was catheterized all throughout then the sphincter was kept open and therefore the fluid collected may not be ejaculatory fluid. All the normal happenings of pelvic organs should be present while collecting the fluid. But that criterion was not met in his study. Some researchers even say that the ejaculatory fluid actually enters the bladder rather than emerging from it. There is no evidence that the fluid collected in the bladder during orgasm will be mixed with the ejaculatory fluid. Is the picture provided by Dr.Schubach is universal or there are normal variations? His study gave an idea over the actual happening but it is not a wholesome study.

Volume of the fluid discharged.

Microscopy of swollen Skene’s glands.

The volume of fluid discharged will vary, from woman to woman, to a few drops to the copious amount of 15 ounces (144 ml). Fifteen ounces is really a copious amount. As the average dimension of a female prostate is 1.3 inches lengthwise, 0.75 inches wide and 0.4 inches in height, the doubt that whether 15 ounces of fluid can be secreted by this gland naturally arises. A container of these dimensions will hold 0.32 oz of fluid on an average. Another study found out 30 to 50 ml of fluid or 1 to 1.7 oz in 30 to 50 seconds. Some researches say that the prostate may swell in size during the orgasm and therefore an allowance of 30 to 50 ml can be made. If it is true then the female prostate has to increase in size 9 times its original size to hold this much amount of fluid. It is also worth noting that the female bladder can retain around 16 oz of fluid which is very close to the amount mentioned as female ejaculate.

The female prostate will produce fluid continuously if she is kept aroused for a long time. Therefore it is also true that she can produce 0.2 to 2.0 oz of ejaculate over multiple orgasms. It is also said that the longer a woman stays aroused, the more fluid she produces. If all these were considered then it is possible that she ejaculates sizable amount of fluid without discharging urine from the bladder. It is true that more research is required to come to a definite conclusion over this subject and probably a transvaginal ultrasonography may be required to document the swelling of prostate during orgasm and the continued discharge of fluid from it.

Health related issues

The massaging of the urethra during G-spot stimulation may have some adverse effects. As the urethra is a highly sensitive organ with multiple nerve endings sensitive to touch, it can be easily irritated with over stimulation and other chemicals or infection. Even friction due to normal intercourse can irritate the area and can cause dysuria (painful urination) and infection (as friction removes the upper layer of cells making passage for bacteria to enter).This usually happens with real virgins with tight vagina and tense pelvic muscles (fear or pain induced muscle contraction). Many times intentional teasing of urethra can lead to irritation and infection. One way of preventing this is to take lot of water and urinate prior and after urethral stimulation or sex. You have to release some fluid from bladder if you are in sex with full bladder. Some even recommend women to drink cranberry juice, or cranberry supplement as its acidic pH may help in preventing bacterial growth in that area. You can even try lesser pressure, massaging or stimulation of the urethra if you feel dysuria, burning sensation, itching or redness in that area. Urethral stimulation can be fun but you should always bear in mind you should not cause infection in the area and trouble yourself.

Wetness concern during stimulation.

Ejaculation if occurs could be small or large in volume and if you intentionally release fluid from bladder or have multiple ejaculations, then the place becomes messier with fluid everywhere. As you usually tend to sleep after the act, tidiness of the place is a more important concern. Keeping towels around may help women with small ejaculates. If they squirt more, then towels alone may not suffice. When will women squirt more no one can say, as it depends on their extent of arousal, lasting of orgasm and number of orgasms. You can resort to spreading plastic sheets over the bed and it can be rolled up and kept aside, if you want to rest after sex. You can even buy McIntosh sheets or disposable sheets, which were used in hospitals to spread over bed. They can even be bought from the local store or pharmacy. You can even opt for trying things in bath tub, while showering or using a second bed for sleeping to experience the post stimulation afterglow better. You can keep these things ready so that you can avoid the messy feel post sex or stimulation and experience the pleasure feel in full. Partner support will always be a welcome sign and it even strengthens the bond.
