Conception

Contraception
The conscious use by sexually active people of chemicals (spermicides), drugs (hormones), devices (condoms, diaphragms, intrauterine devices), surgery, or withdrawal to prevent pregnancy.
Corpus luteum
A structure that forms at the site of an ovarian follicle after it releases an egg. The corpus luteum releases estrogen and progesterone, two hormones necessary for maintaining a pregnancy. If pregnancy occurs, the corpus luteum functions for five or six months. If pregnancy does not occur, it stops functioning. \r\n
