One of the most inefficient methods of contraception still used today. Involves having sex at the time of month at which the woman is least receptive (physically) to pregnancy.

A supposedly-effective/reliable means of avoiding pregnancy, this technique practically guarantees that you will "crank 'em out like an assembly line" on an even and regular basis!
