Mesterolone
Question
What is the role of Mesterolone in increasing the sperm count and motility and what is the mechanism by which it increases?
Answer
In order to answer your question one must initially review how and why testosterone is produced. Gonadotrphin releasing hormone [GRH] is the hormone that controls reproductive function. It is produced and released by a part of the brain called the hypothalamus and in turn controls the production and release of luteinising hormone [LH] and follicle stimulating hormone [FSH] (called gonadotrophins) from the adjacent pituitary gland. LH acts with FSH to stimulate Testosterone production, secreted by the interstitial cells of the testis and responsible for triggering the development of sperm and of many sexual characteristics such as the changes that occur during puberty in the penis and testicles.
Mesterolone is indicated in the treatment of testosterone deficiency or male infertility associated with malfunction of the hypothalamus, pituitary or testicles. The drug is administered orally and the initial recommended dosage is three or four 25mg tablets daily for several months, followed by maintenance therapy of two to three tablets (50-75mg) daily.
It is not recommended in children and contra-indicated when there is a history of previous or existing liver tumours, or in the presence of prostate cancer, as it may stimulate its growth. Mesterolone's molecular structure gives it special properties that set it apart from testosterone and all the drugs derived from testosterone that are used for this type of therapy, in that it is not broken down by the body [metabolised] to oestrogen. This difference almost certainly accounts for the findings that, in its usual therapeutic dosage in normal men, Mesterolone does not significantly depress the release of gonadotrophins from the pituitary. Therefore sperm production [spermatogenesis] is unimpaired by Mesterolone when compared with other drugs used in this area, which suppress and therefore replace the body's natural [endogenous] testosterone. In other words, Mesterolone supplements ones natural testosterone. I hope this explanation helps.

How does it work?
Mesterolone is a derivative of the hormone testosterone. Testosterone is a naturally occurring male hormone known as an androgen. It is produced by the testicles and is the main hormone essential for normal growth and development of the male sex organs and male sexual characteristics. During adult life, testosterone is essential for the production of sperm, the maintenance of sex drive, erectile potency, and the functioning of the prostate gland and other reproductive structures. The natural production of testosterone is controlled by another set of hormones called gonadotrophins, which are released from the pituitary gland in the brain. Low levels of testosterone can cause impotence, decreased sex drive, decreased mental and physical activity, infertility due to decreased sperm production and bone loss. Mesterolone is given when natural testosterone levels are too low. This occurs following castration, or may be due to decreased functioning of the testicles (hypogonadism or eunuchoidism). This can be caused by testicular disease or a deficiency in gonadotrophin production by the pituitary gland. Mesterolone therefore allows the return of normal sexual functioning, and is useful in the treatment of infertility caused by low testosterone levels.
What is it used for?
# Low testosterone levels in men
# Male infertility caused by low testosterone levels
