      I’m fairly certain that if women would get a full disclaimer with all the nasty side effects a pregnancy comes with, they’d give it a second thought… On the other hand, some women insist on having a second baby… And then a third… And a fourth…

          I remember I asked my husband in all seriousness to please kill me. Not in the heat of the moment, I actually meant it.

          I don’t remember the pain. I guess it must have been bad but I cannot even imagine what it felt like or where it was located.

                That was exactly what we concluded. We had a conversation about it, and my wife said “We got lucky and got a perfect kid on the first try. What are the chances of it happening twice?”

                He’s 26 now, and we’re best friends.

        Tbh: I know people who have incredibly easy pregnancies, deliveries and then habe a child that hardly bothers anyone. And then others…not so much.

        And hormones are mighty in what they do to a brain.

    Human face pores are home to tiny, microscopic mites called Demodex.

    They are most active at night, when they leave their follicles to mate on the face and then return to find a new follicle.

    Almost everyone has them. So there are tiny arachnids having sex on your face every night.

        “In” feels like the wrong preposition here, since the creatures involved are all on the same side of you. Next to? It’s more like you’re a room or two away from an orgy and the sound doesn’t really carry.

        It’s not an illness. In most cases they are completely harmless and unavoidable, you get them from your mom as a baby and carry them your whole life. Most people have them. A minority of people can have some skin condition due to them, but it’s quite rare. And yes dogs carry them too, but not an issue for them either.

    Retrograde menstruation.

    Because the feliciano tubes aren’t closed on the ends, where they interact with the ovaries, blood from a period can flow backwards into your abdominal cavity.

    Additionally, a small amount of sperm (if a woman is sexually active and say trying for a baby) can also go the full way and leak into the abdominal cavity.

    So some women can have blood and semen free floating in their abdominal cavity. Between organs

    Edit: autocorrect got me. I meant “fallopian tubes”

        To avoid stickyness what you want to do is, since it’s a protein, freeze dry it with liquid nitrogen as soon as it exits the urethra and viola! no more sticky.

            The peritoneum is very sensitive and blood in the abdominal cavity is a warning for internal bleeding. So it’s very painful for quite some time even when the bleeding is under control.

        Yeah. And it’s a huge problem in the developing world.

        A gynaecologist I used to work with from time to time dedicated her whole retirement to it - she operated hundred of cases per year until she physically could not do it anymore,then she spent another two years teaching in various places until she could no longer do that anymore as well. (By then she was well into her 80ies). She was a saint basically, but without the whole Christian stuff (she had a massive hatred for the church and especially mother Theresa)

    Its possible to stick your tongue inside your nose from inside your mouth. I am among quite a few people that can do it and clean the inside of the nose from boogers.

      Apparently if your tongue isn’t long or flexible enough, the Wikipedia has suggestions, ranging from months of flexing and tongue exercises, to just fucking snipping your frenulum.

        Feels strange at first, then its very handy. Helps unclog the nasal passages. You can even suck on a side passage and spit out what comes out. I once had a piece of string from a corona mask stuck in a side passage and was able to get that out just with my tongue. its also a nice trick so groce out people xD

      I’ve always found this interesting. Human beings (or any vertebrates I suppose) are really more of a colony than a single being. And it’s not just a technicality, it’s meaningful. Much of that colony interacts with your nervous system and affects your moods and behavior. You think you have total control of your mind, but you would think and act differently with a different balance of gut bacteria. Chew on that for a while…

            Take six mg estradiol enanthate injections weekly for two years. Follow up with domperidone-based lactation induction. Supplementing a testosterone blocker would also be useful.

            Warning, this is essentially going on the full hormone therapy trans women go on. You can induce lactation, but it requires being hormonally female for an extended period of time. Look up the effects of mtf hormone therapy, as you would be getting all of them. Also the breast growth is permanent. You have been warned.

              I am not genuinely contemplating doing the hormone therapy, the above comment was in jest. However that is very cool to learn about. I had no idea breast development was a one-way road. These are questions I never thought to ask. Thanks for sharing

        Sometimes regular stimulation is enough. I saw one case where a man took on an orphaned infant where there wasn’t even any animal milk available to hack together formula, and the starving infant attempting to get milk out of his nipple every hour for multiple days was enough to get the one breast to start making milk, and the infant lived thanks to it.

        The need for suckling to stimulate milk production is a catch-22 for women who don’t make enough milk. They have to supplement with formula to prevent “failure to thrive”, but the infant spending some of its sucking time on a bottle instead of a breast reduces their supply even more, so then they have to feed even more formula… There are devices that run a tube to the nipple so the infant can get formula from the tube while at the same time stimulating breast milk production, and they work, but look like a huge pain.

        I think the point being made was that the enzyme used to break down cellulose is only made by bacteria, whereas the enzymes used to break down carbs, fats, and proteins are produced by the pancreas. Digestion is complicated though, teeth and stomach acid are also digesting in a way so it’s all an oversimplification

    When fertile, women have significantly increased mucus volume in their vaginas.

    https://en.wikipedia.org/wiki/Cervix

    Several hundred glands in the endocervix produce 20–60 mg of cervical mucus a day, increasing to 600 mg around the time of ovulation.

          I mean. I did not know it was called mucus.

        I, a vagina-haver, had no idea until a Catholic friend in college mentioned NFP. The secular Fertility Awareness resources I ended up finding all supported my impression this isn’t widely known. That was twenty years ago, though, maybe young people these days are more body-aware?

        Agree it isn’t really gross, I think it’s cool, but it seemed gross-adjacent enough I could get away with sharing in this thread.

          For the uninitiated, NFP is Natural Family Planning - the practice of avoiding coitus during ovulation as a form of birth control. It’s seen as a natural form of birth control compared to artificial birth control in the form of condoms and the pill.

          It’s strange to me that the Catholic Church singles out birth control as needing to be natural, but not much else.

          It’s around 75% effective at preventing pregnancies, but doesn’t stop STIs obviously.

      The real gross fact is that cervical mucus, during ovulation, has the same consistency as egg whites and can be whipped.

      A fun addition to this fact is that vaginal secretions are made from modified plasma. Like that stuff in your blood.

      So TECHNICALLY women don’t just bleed for their period.

    Of all of the cells in your body, less than 45% of them are human. The majority are microorganisms designed to work with your gross-ass self for similarly gross organic meat-bag processes.

        I actually looked this up just for you. Surprisingly low at .3%! While the number of cells are roughly halfish each human and non human, the non human cells weigh so little they only account for around 200 grams of actual weight. Learned something new myself there.

          Wow! I wouldn’t have expected anywhere near that disparity!

          Edit: and thanks for taking the trouble to look it up, too. How did you find that? Was it written somewhere or did you have to do a calculation?

        Topologically, a human gastrointestinal tract is outside of the body.
