Proof that female ejaculation is just pee.

[Note from the authors of “Seriously, Science?”: After nine years with Discover, we’ve been informed that this will be our last month blogging on this platform. Despite being (usually) objective scientists, we have a sentimental streak, and we have spent the last few days reminiscing about the crazy, and often funny, science we have highlighted. Therefore, we have assembled a month-long feast of our favorite science papers. Enjoy!]

Up until now, the scientific literature was pretty much as divided as the internet on whether the large amount of fluid emitted from women upon orgasm represents “real” female ejaculate, or whether it is simply urine (there is a remarkably large body of literature on this topic, both scientific and trashy, and everywhere in between). Previous experiments have focused on determining the liquid’s chemical makeup, finding it to be chemically identical to urine, but these studies ignored the physical source of the copious fluid. Here, the researchers take it one step further by performing ultrasounds before and after ejaculation, as well as testing the biochemical properties of the liquid. It turns out that not only is it chemically identical to urine, but the bladder empties during the period of ejaculation coinciding with orgasm. So there you have it: it’s probably just pee after all!

Nature and Origin of “Squirting” in Female Sexuality.

“INTRODUCTION: During sexual stimulation, some women report the discharge of a noticeable amount of fluid from the urethra, a phenomenon also called “squirting.”

To date, both the nature and the origin of squirting remain controversial. In this investigation, we not only analyzed the biochemical nature of the emitted fluid, but also explored the presence of any pelvic liquid collection that could result from sexual arousal and explain a massive fluid emission.

METHODS: Seven women, without gynecologic abnormalities and who reported recurrent and massive fluid emission during sexual stimulation, underwent provoked sexual arousal. Pelvic ultrasound scans were performed after voluntary urination (US1), and during sexual stimulation just before (US2) and after (US3) squirting. Urea, creatinine, uric acid, and prostatic-specific antigen (PSA) concentrations were assessed in urinary samples before sexual stimulation (BSU) and after squirting (ASU), and squirting sample itself (S).

RESULTS: In all participants, US1 confirmed thorough bladder emptiness. After a variable time of sexual excitation, US2 (just before squirting) showed noticeable bladder filling, and US3 (just after squirting) demonstrated that the bladder had been emptied again. Biochemical analysis of BSU, S, and ASU showed comparable urea, creatinine, and uric acid concentrations in all participants. Yet, whereas PSA was not detected in BSU in six out of seven participants, this antigen was present in S and ASU in five out of seven participants.

CONCLUSIONS: The present data based on ultrasonographic bladder monitoring and biochemical analyses indicate that squirting is essentially the involuntary emission of urine during sexual activity, although a marginal contribution of prostatic secretions to the emitted fluid often exists.”

    Maybe, but I know for sure that female ejaculation fluid does not smell urine at all. How is this explained?

    • Gata Loca

      Fresh urine, more like liquid that was expose quick. Withouth been so long on bladder like taking a lot of water till urine get clear, bcuz you keep bladder full and exposing liquid all time. Just fresh urine.

      • DC Step

        You seem to know a lot. Have you seen female ejaculation and/or tasted it? I think not.

        • Gata Loca

          I’m a female I know my body, you are just dreaming you are a super male that make a woman do something magical, of course by logic and simple biology, where the hell we as woman have and area to store something like that? Yes of course if we carried a baby, not other way, plus is anatomy stupidity the female tigh vagical muscle on orgams to impulse sperm in, that stupid eyaculation will take things out, is simple nature stupid and against why sex is, for reproduction. Is taste diferent bcuz is mix with your semen, and her true vagina semen that is not liquid is more like a male semen and in small parts, of course if you want to believe you are a sex god what ever, but is not when you are having sex as female I can tell you the desire of pee happens and could be similar to arousal and when you are in certain movement or friction or position you are stimulating bladder too. But what dream on!

          • DC Step

            LOL. Girl, I get it. You can’t do it, so it can’t be real for any other woman. I wasn’t trying to diss you, but you clearly don’t know what you’re talking about.

    We thus achieve a rational counterdemonstration of Intelligent Design.

  • Ld_Elon_Postman_RoyalMale

    Intelligent design ‘is’ a universal process. You’ll never know what the greater cause is because your rational is so small. Just a bit./1.with many zeros…/0.

  • Ld_Elon_Postman_RoyalMale

    Intelligent design is thus a fundamental…

  • Not_that_anyone_cares, but…

    Couldn’t they have just put a dye in the urine and [edit to add; were there ever any question about it] resolved this cheaply and quickly decades ago?

    The first thing I thought of was an old antibiotic that colored the urine. Simple, inexpensive and harmless.

    • Uncle Al

      Good call! Antibacterial methylene blue orally. Dope with a few ppm of ophthalmic sodium fluorescein (uranine) locally.

  • DC Step

    If it’s urine, why does it taste sweet???

    • Gata Loca

      Bcuz is fresh, is more like the stimulation come near the bladder in some positions so is more like moving out fresh urine. And of course there was sex so you are testing several stuff including semen.

      • DC Step

        I’ve tasted it before any semen was introduced. It’s NOT urine. It tastes like glucose or some sweetener. It is very sweet tasting. My partner empties her bladder before sex. (I know that doesn’t mean that new urine isn’t produced). The stimulation includes clitoral, G-spot and vagina, but bigger orgasms seem to produce more ejaculation. Orgasms and ejaculation can happen at the same time, but not necessarily, in our experience.

  • Tarah Alexander

    I am a female gusher and my husband says it taste sweet and does not smell like urine and explain to me after i gush, howcome i can go use the bathroom right after and urinate the same amount or more.. I can’t help it either if i experience an awesome orgasm. It gushes out of me without even meaning to.

    • Gata Loca

      Is fresh urine, come on, you are woman you supposed to know your body long before sex, I know that is not posible bcuz we don’t have any area to save that large amounts of liquid except bladder or of course you are pregnant and carrying a baby.

    • DC Step

      Tarah, I agree with you. It’s NOT urine, or urine is a very low percentage. My lady’s ejaculation is very sweet, like glucose or some sweetener.

      I hope you enjoy it as much as we do. It’s added an extra element to our sex, on top of the great feeling and her huge orgasms, we’ve now come to expect this wonderful event. Don’t let know-nothing people, with no direct experience tell you it’s not what you think.

  • Tarah Alexander

    Honestly I’d like to be a part of those “tests” because I’d like to know myself

  • Evangeline Kiser

    I’m a squirter, depending on the type of orgasm, and if I choose to or hold it back. It will gush or sometimes shoot across the room . I will say this- if I’ve urinated right before then the liquid is clear and sweet and smells and tastes (I’ve been told) like my creamy ejaculate, then and later. I can also urinate immediately after, bladder feels full. If I haven’t urinated then it initially smells fresh but if I don’t launder or clean up then occasionally there will be a faint urine scent days later. So honestly? I’m not sure: but I’m not bothered by whether it’s fresh urine or some mystery liquid: the study does seem pretty clear. I’m extremely comfortable with my sexual responses and squirting is it’s own kind of amazing. squirting or not squirting, neither is anything to be ashamed of, ladies. Love your yoni, whatever she does.
