Dr. Alvin Lin answered

Unprotected sex: Are you asking about the birds and the bees? The actual mechanics of (unprotected) sex? Artificial reproductive techniques (art) such as in vitro fertilization (ivf) can also "cause" pregnancy w/o sexual intercourse. Check out http://health.Yahoo.Net/experts/womentoday/mechanics-pregnancy. Bottom line, guy puts penis inside vagina & releases sperm, one of which joins female egg causing pregnancy.
