I don't think women have a different number holes topographically speaking.

The topologist can't tell his coffee cup from his doughnut.

    Generally, biologically speaking:

    Men have a urethra and an anus.

    Women have a urethra, and anus, and a vagina.

    Presumably, discounting mutations, birth defects, serious injuries, etc, most people have the same number of uh... head/face holes.

    ...

    Allowing for rarer cases:

    Also... intersex people exist... there have been at least a few recorded instances of duplicate and/or forking dongs...

    And I guess we could also consider varying kinds of conjoined twins.

    ...

    Also also, we could argue about whether milk producing mammaries constitute a topological 'hole'.

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

    Vaginas, milk ducts, pores, etc in a topological sense, are not holes, just dents, like the recepticle part of a cup with a handle.

    I mentioned noses and ears before deleting them, because the ENT region is really complicated for a non topologist/biologist to be able to tell if they can be interpreted as holes or not. Luckily for me in this discussion the system is identical for men and women.

    Derp.

    Looks like I need to complexify the manifolds of my own brain, haha!

    Wait, the tear ducts count... but the eyesocket itself doesn't?

    Huh.

    I would have intuitively thought the hole the optic nerve goes through counts, but I guess thats not really a uh, topologically true hole, as its mostly just a void in your skull.

    I think their point was that the hole has to go all the way though for it to count topologically

    The vagina ends at the uterus, and milk ducts don't go all the way through either

    Urethra doesn't go anywhere either except for bladder, then nephrons (kidneys)...

    Something similar applies to ears, right? And nose... But,

    Also, what about the pores in my skin? :O

    The problem is the nostrils.if it was just an indentation into the lungs, it's one hole: digestive tract.

    The nostrils divide the breathing passage into two, then join up again. From the air to the lungs is an indentation, but does the tissue separating the nostrils create two separate complete topographic holes?

    Same for the ears; where do they join in on this system? Idfk, I'm not a doctor or a topologist

    Ah, you got me on the nostrils. Alright..

    My point was that the discussion is silly/ absurd/ meaningless. Yet here I am... Caught in it.

    So... Ears. Those have a membrane (so the air pressure inside transmits the sound to small bones)... I was considering that given a (healthy) membrane the hole is just a cavity. Bt then, the other side does have air. No idea how does it go in and out. But scuba or free divers do compensate the pressure on the other side of the membrane when descending... So the air in there goes in and out of the body in seconds. Might be connected to... Nostrils? Haha. My best guesstimate.

    Fuck this game xD

    I mean it's not might, it is connected to the nostrils. that's why for doctors it's ENT and the infections can spread between those areas.

    https://chicagoent.com/ear-nose-throat/how-are-the-ear-nose-and-throat-connected/

    The ears, nose, and throat are part of your upper respiratory system. These three are linked through several canals and tubes and share the same mucous membranes.
    Because they’re all connected, the ears, nose, and throat can function as one system, with each part supporting the whole. That’s why when there’s a problem in one area, it may also affect the other two.
    For example, when you get a cold, you may also have a cough, sore throat, ear pain, and stuffy nose. Even though the ears, nose, and throat have very different functions, they all work together to help you hear, breathe, and talk.
    The throat connects your nose to your mouth and links to the esophagus and lungs. Your ears also drain into the throat.
    The eustachian tube drains fluid from your ears into your throat via the nasopharynx. At the same time, the nasal passages connect to your ears.
    Through these routes, a viral or bacterial infection in either your ears, nose, or throat can find its way into the others. For instance, the ENT system can be affected by the same problems, including infections, congestion, swelling, and post-nasal dripping.
