Conception Period of Women.
Harrisburg PA: Medical Arts Publishing, 1934. Second edition. Ogino studied infertility and developed a method to estimate the fertile period of the menstrual cycle based on the length of a woman's past cycles. This knowledge could be used by couples seeking pregnancy to time intercourse so as to maximize the chances of conception. (Wikipedia)
