* * *pro·ges·to·gen also pro·ges·ta·gen -'jes-tə-jən n a naturally occurring or synthetic progestational steroid
* * *n.one of a group of naturally occurring or synthetic steroid hormones, including progesterone, that maintain the normal course of pregnancy. Progestogens are used to treat premenstrual tension, amenorrhoea, and abnormal bleeding from the uterus. Because they prevent ovulation, progestogens are a major constituent of oral contraceptive and other forms of hormonal contraception. Synthetic progestogens may be taken by mouth but the naturally occurring hormone must be given by intramuscular injection or subcutaneous implant, as it is rapidly broken down in the liver.
