This property of DHT comes into particular utility when it is administered exogenously, and this is to be discussed in further detail in the next section. medical steroids Steroid dosages. DHT, estrogen, and the prostateWhen it comes to sex hormones, few things are as misunderstood by the general consumer as the relationship of the prostate to DHT. The inaccurate and overly simplistic attitude that DHT is responsible for prostate hypertrophy, and even prostate cancer predominates amongst most people. The real situation is, of course, much more complex. medical steroids Beginner steroid cycle. One must understand that there are marked differences between healthy prostate growth (developmental growth), prostate growth due to BPH, and cancerous prostate growth. The first period of prostate growth, deemed developmental growth, is connected to puberty and the testicular secretion of androgens. This takes the prostate from its prepubertal dormancy to the normal sized, healthy, and functional prostate gland of an adult. medical steroids Steroid dosages. During the early and mid adult years the prostate stays at this stage, despite the constant high levels of androgens in the body. However, if androgens are blocked in the body then the adult prostate will shrink in size. This can occur by castration, or even by blockade of 5-AR (recall that DHT is the active androgen in the prostate). Later in life, there is often a second stage of growth. This growth is deemed benign prostate hypertrophy (BPH) and this growth occurs in a wholly different hormonal environment than that of developmental growth. Evidence is mounting that the existence of a high estrogen / androgen ratio - a condition common in older men - is highly correlated to the development of BPH. Experimental studies have shown the inability of androgens with saturated A rings (DHT related) to induce an initial condition of prostate hypertrophy. These compounds are non- aromatizable. Aromatizable androgens on the other hand, such as testosterone or androstenedione can induce hyperplasic modifications of the prostate of monkeys, but these effects are reversed by the addition of an aromatase inhibitor. So apparently, estrogen is a causative factor in BPH or, probably more accurately, estrogen in the presence of a minimum, permissive amount of androgen. None of this may come as news to many of you, but I bet that very few of you know that DHT can actually be used to treat BPH!! How can it do that? It basically does this by replacing the testosterone in the body, which then has the effect of reducing the amount of estrogen in the body. As I started to explain before, DHT is a strong androgen that will signal the pituitary to decrease the production of gonadotropins. The decrease in gonadotropins will then cause less testosterone to be produced which will in turn cause the estrogen levels to drop. The resulting change in the hormonal milieu (high DHT, low estrogen) then apparently results in a regression of BPH. The clinical application of this theory is discussed in US patent 5,648,350 "Dihydrotestosterone for use in androgenotherapy". The following illustrates the results:"In 27 subjects in which the plasma DHT level was controlled, so as to modulate the administered doses, said levels have been increased to 2. 5 to 6 ng/ml.
