Mucus produced by the cervix that permits passage of sperm during ovulation, and prevents infection.
Lower section of the uterus that protrudes into the vagina, through which the sperm pass to reach the uterus.
The false appearance of pregnancy due to changes in hormonal levels. A chemical pregnancy occurs when a fertilized egg does not implant into the uterine wall. If a pregnancy test is taken just at the right time it will be positive, however, when a repeat test is taken several days later it will be negative. This results in an early miscarriage.
Fertilization; when the sperm meets and penetrates the egg.
Stimulation of the ovaries with various hormonal medications in order to develop as many follicles as possible, as well as to control the timing of ovulation.
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.
Storage of organs or tissues at very low temperatures. Embryos that are not used in an ART cycle can be cryopreserved for future use (e.g. “egg freezing” or “embryo freezing”).
