PROGESTATIONAL ACTIVITY IN THE STEROIDS Leave a comment

Among the different effects that steroids have such as aromatization, promoting the development of muscle mass, increasing sports performance we can also see that there is a progestational activity to which very rarely or never is paid attention.

Among the different effects that steroids have such as aromatization, promoting the development of muscle mass, increasing sports performance we can also see that there is a progestational activity to which very rarely or never is paid attention.

The progestational activity of steroids stimulates in the male body the production of hormones such as progesterone, estrogen and consequently prolactin. In women it is a pre-menstruation phase and it is important for the development of the mammary gland and the predisposition of the body to keep a pregnancy stable.

Some steroids such as nandrolone and its derivatives and trenbolone have a moderate progestational activity that in some individuals can lead to problems such as gynecomastia and in the worst case prolactin increase, which would accelerate the development of the mammary gland and stimulate the milk production. Another big problem with prolactin is the total loss of libido and sexual desire, the man loses the ability to have or maintain an erection due to this hormone.

Many times we have heard or read about the deca-dick or the train-dick, the explanation that many give to this effect is for the suppression of the hypothalamic axis, but if it were because of this it would really happen when using another type of anabolic steroids such as the testosterone or the equipoise.

The real reason is the high levels of prolactin in some individuals more sensitive to the progestational activity of these substances. http://scielo.isciii.es/pdf/urol/v63n8/08.pdf. In this article we can see how high prolactin is related to erectile dysfunction even when testosterone is at normal levels and as we can also see that it usually disappears when regulating prolactin levels in man.

It is important to note that gynecomastia caused by high levels of prolactin can not be stopped only with tamoxifen or arimidex since a drug such as bromocriptine or cabergoline is necessary in order to keep prolactin levels at bay.
