Secretion known as uterine milk that developes prior to the placenta

56
Q

What happens to the seminiferous degenererates

A

The leydig cells can grow producing same or more testosterone

57
Q

What is the stereocilia

A

Moves sperm from the head to the tail and allows sperm to absorb fluid allowing sperm to survive longer and give them more space to swim
