Glossary
Conception
The fertilization of a woman's egg by a man's sperm resulting in the formation of an embryo.
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
Cryopreservation
Storage of organs or tissues at very low temperatures. Embryos that are not used in an ART cycle can be cryopreserved for future use.
