if vaginas are self cleaning organs, and constantly outflowing acidic fluids- how in the world does sperm swim against the current to impregnate someone?

Question

Does the semen’s alkalinity deactivate it? How is something so small able to swim against the current in tight tissues?

Answer 1

It’s not like there’s a swift-moving river up there. More like a slow, steady stream. And the sperm have their tails to swim upstream faster, like salmon swimming up a stream. Most don’t make it, but there are a lot of them.
