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

A woman’s reproductive tract varies in acidity. During ovulation it becomes less acidic and the cervical mucus thins to make it easier for sperm to enter. While the vagina is acidic, the cervix and womb are much friendlier to sperm. The walls of the womb contract and ripple to help the sperm reach the fallopian tubes. The fluid in the tube further helps sperm, providing it with a nutrient boost to help it on the final leg of it’s journey.
