Science of Sex: Female Ejaculation

Guess what guys?! I’ve been writing the Science of Sex once a month for over a year. That’s pretty awesome! I am definitely glad to take suggestions like I did with this post. Just leave a comment, and it could become next month’s topic!

To be honest, I didn’t really want to write a post about female ejaculation, but this is a request from a friend, so I decided to dip a toe into the water — if that’s what it even is.

Therein really lies the issue with female ejaculation, FE for short. Researchers have yet to prove what exactly is it; although, at least one study have claimed it’s just pee. Whenever a science team makes this claim, however, women are not so happy about it. It’s similar to when reports arise claiming that no G-spot exists.

Let’s start with what we do know:

  • All women are able to squirt a small amount of liquid, prostatic secretion, which contains prostate-specific antigen, that’s created in the Skene’s glands, also known as the paraurethral glands. The fluid is milky and white.
  • Some women are able to ejaculate a larger amount of liquid. It also comes from the urethra but is much greater in volume. This liquid is stored in the bladder before ejaculation.
  • Some women may be able to ejaculate but do not, so the liquid moves backward. This is known as retrograde ejaculation.

Here’s something else we know: FE in porn is often fakes. A woman’s vagina is filled with water, and she pushes it out. It looks good from the camera, but it’s not coming from the urethra.

But let’s back up. There’s one survey that I cannot ignore when talking about female ejaculation. In this survey, researchers used ultrasounds to view bladders. The women used the bathrooms to empty their bladders, and this was verified by the ultrasound. The women began stimulating themselves. After these women had orgasms, researchers collected samples from the liquid. Researchers used the ultrasound to show that the bladder was again empty. Although, we aren’t aware of how long it was between scans.

Some of the liquid contained PSA, but researchers determined there was also urine by looking for urea, creatinine, and uric acid (although, there were no trends between levels measured before, during and after FE). They concluded that squirting prostatic fluid and gushing were two different activities. This was not the first study to come to this conclusion.

However, at least five previous studies have also looked for these chemical markers and found no sign of creatinine in FE.

The one thing that struck me, assuming the newer French study is accurate, was that perhaps any fluid in the bladder would contain trace amounts of the chemicals that scientists tested for in the FE. Could it be not that this means these chemicals are markers of urine but simply markers of fluid that has been contained in the bladder? If that were the case, how would we absolutely define what is urine and what isn’t?

According to Dr. Debby Bernick, female ejaculate is very diluted urine. This is backed up by anecdotal evidence that FE has a different smell/taste from urine. Dr. Grafenberg also described FE as having “no urinary character.”

I’ve also read from medical professionals that this diluted urine has not been filtered by the kidneys and perhaps could not be due to the volume of fluid.

I don’t know of any studies have that tested the following claim, but it’s worth mentioning. Medications that affect urine do not necessarily affect FE, perhaps because it’s not filtered by the kidneys.

The only thing that remains for sure after the 2015 study is that more research must be done, especially with a control group larger than seven women. And scientists must ask more specific questions than “Does FE contain these chemical markers?”.

Some studies have asked better questions than this one. For example, the writers ponder whether FE might serve an antimicrobial purpose, which could spell good news for people who struggle with UTIs from sex.

Other papers remind us that female ejaculation was readily accepted as a sexual function thousands of years ago, but society seems to have forgotten this a time or two.

But as it the case with so many aspects of female sexuality, we need to spend more money and time to learn more.
