pro·ges·to·gen

(prō-jes'tō-jen),
1. Any agent capable of producing biologic effects similar to those of progesterone; most progestogens are steroids like the natural hormones.
2. A synthetic derivative from testosterone or progesterone that has some of the physiologic activity and pharmacologic effects of progesterone; progesterone is antiestrogenic, whereas some progestogens have estrogenic or androgenic properties in addition to progestational activity.

progestogen

One of a group of drugs chemically and pharmacologically similar to the natural hormone PROGESTERONE. They are used in oral contraceptives to interfere with ovulation, to alter the womb lining so that it is less receptive to a fertilized egg and to make the mucus in the cervix less readily penetrable by sperms. They are also used to treat menstrual disorders and cancers that are being promoted by oestrogens.

Lidegaard and colleagues' previous study, which revealed similar differences in risk between levonorgestrel and the newer progestogens, argued that because no declining risk was seen after the first few months of use for women using levonorgestrel-containing pills, as would be expected, left-censoring bias might have occurred, making the risk of VTE associated with levonorgestrel seem artificially low compared with that seen with drospirenone, which was introduced in 2001.
In the words of Jacques Rossouw, principal investigator of the WHI study: 'The Women's Health Initiative study results tell us that during one year, among 10 000 postmenopausal women with a uterus (as opposed to those who have had the uterus removed) who are taking oestrogen plus progestogen, 8 more will have invasive breast cancer, 7 more will have a heart attack, 8 more will have a stroke, and 18 more will have blood clot in the lungs and legs, than will a similar group of 10 000 women not taking these hormones.
Progestogens are sometimes used as a diagnostic aid to determine whether estrogen is being produced.
Nor should women who are on HRT substitute creams for their progestogen pills or patches - they could be putting themselves at risk of cancer of the uterus.
Progestogen, known in America as progestin, is a synthetic form of the natural hormone progesterone.
It is standard practice to add a progestogen (in this case, MPA) to estrogen therapy for any woman with an intact uterus to guard against any increased risk for uterine cancer associated with estrogen alone.
PITTSBURGH -- Aside from the negative findings of the WHI Estrogen/Progestin study, not much is discussed about the role of progestogens (progestin and progesterone) as part of a hormone therapy (HT) regimen.
The panel could not reach a consensus in the following areas because of conflicting or insufficient evidence: whether HT was associated with an early risk of CHD, whether women doing well on long-term HT should discontinue treatment, and whether a continuous combined EPT regimen has an effect that is different from continuous estrogen with sequential progestogen.
These custom-made formulations of estrogen and or progestogens are prepared in gels, suppositories, sublingual tablets, or other formulations, according to NAMS.
Injectable contraceptives contain only progestogens and are administered every two or three months.
Some progestogens negatively affect these bodily functions and some have no effect.
