The following assumes you have already an understanding of the G-spot.
Do women ejaculate? Turns out some women do so noticeably, and many women do so in amounts so small it goes unnoticed. Reports of women experiencing a “gush” of fluid at orgasm go back many centuries1, but it’s only fairly recently that (Western) science has taken these stories seriously.
Many explain away the fluid some women eject from the urethra at climax as urine resulting from momentary loss of bladder control. While this might occur in a very small number of women, it does not explain what many women experience, or what science is now finding. Women who ejaculate, and their partners, report that the fluid doesn’t look like urine and doesn’t smell like urine, and a number of chemical analyses have found that it is not urine. Ejaculating women produce a nearly clear fluid which has only trace amounts of uric acid; this indicates the fluid comes through the urethra, but does not come from the bladder. Chemically the fluid is very similar to the fluid from the male prostate.
Study has shown that the fluid comes from the “female prostate”, more properly known as the paraurethralglands, and often referred to as the G-Spot. During gestation males and females start with the same tissues, it’s only after sex differentiation at about 40 days that the genitals begin to look different in the male and female fetus. The tissue which becomes the prostate in the male does not just disappear in the female, it becomes the paraurethral glands which surround the urethra. Based on postmortem dissections, we know that the amount of glandular tissue varies from woman to woman, and some women have no discernible glandular tissue in their G-spot. One study found that two thirds of women of reproductive age had such tissue.2
The paraurethral glands produce fluid when a woman is highly aroused. Because the glands open into the urethra, the contractions of orgasm force this fluid into the urethra, and out of the body, creating an ejaculation in some women, but only a dribble in others. In a study done by Dr. Santamaría Cabello3, prostate-specific antigen (PSA) was found in the post orgasm urine samples of 75% of the women studied. The PSA could only come from the paraurethral glands, indicating apparent ejaculation. Most of these women did not report an ejaculation, suggesting the amount of fluid was small, or the ejaculation went into the bladder. With only 24 participants, the study is somewhat limited, but it does suggest that most women release some fluid when they climax. On the other hand, those who have done good studies estimate the percentage of women who ejaculate at 5% to 15%. That would mean 50% to 60% of women produce some of the same fluid, but do not ejaculate.
There are those who say all women can “learn” how to ejaculate, and there are no shortage of web sites, books, and videos that claim they can teach “any women to ejaculate.” Biology, however, does not support this. Women who don’t have any glandular tissue can’t produce anything to ejaculate. Other woman don’t have enough glandular tissue to produce the amount of fluid needed to ejaculate. It has been suggested that a woman can somehow increase the amount of glandular tissue in her G-spot to make ejaculation possible, but no one has demonstrated this or suggested a reasonable account of how it would happen. As it stands now, the best science says some women do ejaculate, some women are holding back and could ejaculate, but the vast majority are physiologically unable to ejaculate.4
Lack of understanding of this phenomenon has caused some women great anguish. Worried that she is urinating, or accused of such by her husband, a woman may find the only way to avoid ejaculating is to not orgasm at all. Finding out she is normal, and convincing her husband she is not “peeing on him” can make a huge improvement on an ejaculating woman’s sex life. Since female ejaculation can be several times the volume of semen, and because the fluid is thinner than male ejaculate, some precautions may be need for women who ejaculate. Being very fluid, FE can quickly soak through several layers of towels and leave a wet spot on the bed. Some couples resort to waterproof mattress covers, but this is usually not necessary; a single towel with a layer of plastic under it is sufficient. Just keep a piece of an old shower curtain in the night table drawer!
Ironically, growing awareness of female ejaculation has created another problem; women (or their husbands) who worry that there is something wrong with them because they don’t ejaculate. Some folks have become “female ejaculation evangelists” claiming that all women can, and those who don’t are missing out on the best sex possible. A part of the zeal these folks exhibit may be based on a wrong assumption about cause and effect. Many women who ejaculate say their best orgasms are accompanied by ejaculation, and from this some reason that ejaculation causes the orgasm to be better. A more likely hypothesis is that only strong orgasms cause ejaculation in those women who are able to ejaculate. The idea that the best “dry orgasm” of a non-ejaculator is inferior to the “wet orgasms” of ejaculators is completely unsupported. Additionally, some women say their dry and ejaculatory orgasms are very different, and a few of these women say they feel unsatisfied without a “real” or dry orgasm at the end. Bottom line: no woman should feel she is being cheated because she doesn’t need a pile of towels under her when she has sex, and no man should put such an idea on his wife.
Another problem is that the porn industry has gotten into female ejaculation in a big way. As with everything they do, besides distorting reality to a ridiculous point, they make things up. Pornography and a number web sites have encouraged the idea that all woman can ejaculate. They have also greatly exaggerated the quantity of fluid ejected. Stories of putting out a quart or more of fluid in an hour or so are just that; stories. There’s no way for glands that produce FE to make that much that quickly. Any “demonstration” of a large amount of fluid being “ejaculated” is faked – either by putting fluid into the vagina before filming, or by having the woman urinate. Besides, women who ejaculate report that it requires them to be very relaxed and very aroused – both of which are difficult if not impossible in the setting of filming pornography. Indeed, research on female ejaculation has often times been hampered by the inability of women to ejaculate on command or in a laboratory setting.
That said, some women do release much more fluid than the typical FE. This was a frequent point of argument on Dr. Perry’s (co-author of The G-spot) now defunct “G-spot list”. Dr. Perry said, “[Beverly] Whipple and I continue to reserve the term “ejaculate” for the fluid that comes from the homologous prostate glands in the female. It is only a few teaspoons at best.” Perry and others suggest that release of larger amounts of fluid are a different phenomenon and from another source. The best current theory, one that fits various studies and chemical analysis, is that prolonged high levels of arousal cause some people’s kidneys to rapidly produce very dilute urine. Dr. Gary Schubach studied eight women who experienced large quantities of ejaculation.5 The bladder was isolated by a catheter so what came from the urethra could be separated from what came from the bladder. All eight women released fluid from the bladder when they “ejaculated” while four of the women also release a fluid that bypassed the catheter, meaning it came from the urethra but not the bladder. The fluid from the bladder was very dilute urine – much lower in creatinine and urea than normal urine. This supports the idea that high levels of arousal can result in an unusual fluid in the bladder. This means half the women released both “female ejaculate” and dilute urine, while the other half released dilute urine but no discernible ejaculate. Add those who emit only the ejaculate without any fluid from the bladder, and there are three forms of fluid release possible when a woman orgasms, and those who release no fluid.
Regardless of what fluid does or does not accompany your orgasm (or that of your lady) enjoy it as how God made you.
