contract to bring testes closer to the body. Relax to bring testes farther away from the body.

to ensure optimal temperature for sperm production
The stage of follicular development when the primary oocyte has been surrounded by a layer of follicular cells.
primordial follicle
Causes muscle contraction in the female to help sperm find the oocyte.
prostaglandins
Where fertilization occurs.
uterine/fallopian tubes
