The hormone progesterone.
A general term that covers the female steroid hormones related to progesterone.
The general term for the natural and synthetic female hormones such as progesterone.
Any natural or synthetic progestational hormone.
A natural or synthetic hormone with effects similar to progesterone, an essential hormone of the female reproductive system. A woman with an intact uterus who takes hormone replacement therapy should use a combination of estrogen and progestin to reduce the risk of endometrial cancer associated with estrogen alone. Taken with estrogen, progestin limits the growth and buildup of the lining of the uterus, which is associated with cancer. Progestin is usually administered as a tablet. Some women who are receiving hormone replacement therapy take progestin along with estrogen every day, while others take it for only the first 12 to 14 days of the month. Women who take progestin for only part of the month are likely to have vaginal bleeding once the progestin has been withdrawn. Women who take progestin every day can take smaller doses. They may still have irregular bleeding for the first 6 months.
A corpus luteum hormone that prepares the endometrium for implantation of the fertilized ovum.
Synthetic or “look-alike” progesterone, called medroxyprogesterone. The chemical structure of medroxyprogesterone resembles that of natural progesterone, but the differences can result in different responses.
Any of a group of natural hormones released by the corpus luteum, placenta, or adrenal cortex; also made synthetically.
Any hormone, whether occurring naturally or synthesized, that produces similar effects as progesterone.
