Ogino theory - Ogino theory

Japanese: 荻野説 - おぎのせつ

This theory was announced by Ogino Kyusaku (1882-1975) in 1924. It states that "a woman's ovulation period is the five days from the 16th to the 12th day before her expected menstrual period, regardless of the menstrual cycle." The Ogino Method of Birth Control is a method of contraception during these five days plus the three days during which sperm can survive in the uterus, for a total of eight days. Initially, there was a great deal of opposition from both within Japan and overseas, but it is now internationally recognized and provides a scientific basis for understanding women's menstruation, pregnancy, and contraception. →Basal body temperature

1924年荻野久作〔1882-1975〕の発表した説。〈女性の排卵時期は，月経周期に関係なく，予定月経前第16日から第12日に至る５日間である〉というもの。オギノ式受胎調節とは，この５日に子宮内精子生存可能期の３日を加えた８日間を避妊するもの。当初は内外から多数の反論があったが，現在では国際的に認められ，女性の生理の理解や妊娠，避妊に関し科学的根拠を与えている。→基礎体温
