Do all women ejaculate and where does it come from?

Do All Women Ejaculate?
Given that all women have a prostate gland they all likely produce ejaculate, even if they are not aware of it. The fluid may seep out and mix unnoticed with other body fluids rather than being a distinctive gush of liquid during sexual activity. The prostate probably contributes regularly to the moisture present at the vulva, as indicated by the presence of PAP on their underwear. In the absence of or in conjunction with sexual arousal the prostate may overflow causing the fluid to seep out through the urethra. This release of fluid could be caused by the blood engorgement of the surrounding tissues and the pressures placed on the vaginal wall during sexual arousal and internal stimulation. The fluid in the prostate would likely be released or expelled during orgasm when the pelvic muscles contract. While the volume of ejaculate released may vary from woman to woman it is likely present in all women, and they do not have voluntary control over its release.

Where Does Ejaculate Come From?
Very little medical research has addressed the source or sources of female ejaculate. The research that has been completed often provides conflicting results. Some research concludes it is only fluid from the female prostate while other research says it is mostly liquid from the bladder with trace amounts of fluid from the female prostate. It is my believe that in some cases all of the fluid emitted from a woman's urethra is from the female prostate, in other cases is a mixture of fluid from the female prostate and bladder, and in other cases it is only from the bladder. We simply do not know where the fluid originates from in every instance.

How can you tell if a woman is releasing fluid from her bladder or prostate? This is a question that cannot be answered outside a medical lab. There is no accurate way of determining whether a woman is voluntarily or involuntarily releasing liquid from her bladder or ejaculating prostatic fluid. These fluids all exit the body through the urethra so the visible source is the same for them all. I'm not aware of any color, taste, or scent test that can be applied to the expelled liquid that will accurately distinguish them from one another. We are left with no other choice than to see them as indistinguishable, the same.

In her book The Clitoral Truth Rebecca Chalker states a simple smell test will tell you if it is urine or ejaculate. If the fluid has an acrid scent it is urine. This may be true but what difference does or should it make? My concern is that if a woman or her partner decides she is releasing liquid from her bladder then they may see it as undesirable and/or inappropriate. My position is, it does not matter what type of fluid is expelled, and being concerned about it creates a barrier to pleasure for women. It is okay to be curious about these fluids, that is only natural, but it is inappropriate to judge them.

If you read the information presented on the website of Dr. Gary Schubach he states his research has shown the majority of the fluid that is expelled originates in the bladder, but the expelled fluid is not quite normal urine. In his research the woman's bladder was emptied using a catheter prior to orgasm. During orgasm a catheter was in place and connected to a collection bag. Analysis of the fluid expelled during orgasm is the basis for his claim. There is one flaw with his methodology, the bladder sphincter is normally closed. If it were not, liquid in the bladder would simply flow out and there would be no "ejaculation" of fluid. What is the significance of creating an artificial passage and collecting the fluid expelled from the bladder during pelvic muscles contractions? During orgasm does this passage normally exist even if only momentarily? Some claim otherwise or that ejaculate actually enters the bladder rather than exiting from it. Even if fluid does collect in the bladder during sexual arousal would it normally be expelled during orgasm? Are all women the same or are there "normal variations?" Dr. Schubach's research is important but it provides only part of the picture.

The following series of images show how much the bladder, the bright white area in the lower right, increased in size during sexual arousal in one woman. Does it provide evidence to indicate the origin of female ejaculate in some instances? I know from personal experience that when my kidneys produce increased volumes of fluid it is clear and odorless when released from my bladder. Does sexual arousal in some women result in increased kidney output? These images were taken during research into the use of MRI to observe female sexual arousal and were not intended to provide evidence of the origins of female ejaculate.
