1.) The human reproductive system hasn't changed drastically simply because it works. There are minor problems relating to the system but until they start hindering fertility and childbirth on a major level, the system will not change.

2.) The reproductive systems work like the engine of a car, if one tiny part isn't functioning right, the entire entity can't function. Something as small as a degree difference of the sperm could botch two people's trys at pregnancy. If not everything in the system is working to perfection, the whole system will suffer.
