There are lots of different ways to prevent pregnancy, and the variety of methods are rarely covered in school, from what I hear. When I attended school, there was no sex education whatsoever. Later on, schools were caught up in "abstinence only" education, and today it varies from place to place at the whims of state and local politics. So I should not be surprised at how many people do not know the mechanics of how birth controls methods work, even if they use those methods. Minute Earth takes an overview of the most common modern birth control methods and explains what they do to interrupt the process of beginning a pregnancy. (via Geeks Are Sexy)
The ovaries are not factories-- they do not "manufacture" eggs. Females are born with all the eggs they will ever have, and begin "ripening" and releasing (usually) one roughly every 28 days after puberty.
ReplyDeleteTesticles, OTOH, actually are factories; males normally produce sperm from puberty for the remainder of their lives.
