78% of men orgasm 75-100% of the time. 66% of women orgasm with
masturbation 75-100% of the time. 87% of men.
Fallopian Tubes
isthmus, ampulla, & infundibulum
cilia-lined
egg travels through the tube by the action of the cilia
fertilization occurs in the infundibulum (most successful location)
infundibulum curves + meets fimbraiae
you can conceive and not get pregnant because it might not implant
