[13] [16] There are far fewer studies evaluating the side effects of 5α-reductase inhibitors in women. However, due to the known role of DHT in male sexual differentiation, 5α-reductase inhibitors may cause birth defects such as ambiguous genitalia in the male fetuses of pregnant women. As such, they are not used in women during pregnancy. [36]
5α-Reductase inhibitors (5-ARIs), also known as dihydrotestosterone (DHT) blockers, are a class of medications with antiandrogenic effects which are used primarily in the treatment of enlarged prostate and scalp hair loss. They are also sometimes used to treat excess hair growth in women and as a component of hormone therapy for transgender ...
If SRY exists, then the gonads develop as testes, and commence the production of androgen hormones, mainly testosterone, dihydrotestosterone (DHT) and androstenedione; production of testosterone and conversion into dihydrotestosterone during weeks 6 to 12 of pregnancy are key factors in the production of a male fetus's penis, scrotum and ...
Two of three isozymes of 5αR can catalyze the transformation of T to DHT, but it is only 5αR2D that causes 46XY, DSD. 5αR2 is encoded by the gene SRD5A2 which is located on the short arm of chromosome 2 and contains five exons and four introns. 5αR2 consists of 254 amino acid residues with reported mutations at 67 of them with multiple different mutations at some residues.
The best way to prevent DHT from binding to your hair follicles and causing hair loss is to use the right DHT-blocking ingredients. Here are the top ingredients to look for in DHT shampoo:
The anabolic effects are important in both males and females, although females have lower circulating levels of androgens. The physiologically most important androgens are testosterone (T) and dihydrotestosterone (DHT), which are considered classical androgens because their role in human health was discovered in 1930s.

In 2002, the Women's Health Initiative study (WHI) that was designed to demonstrate additional benefits of conventional hormone therapy (study participants were given Prempro or a placebo) was terminated prematurely after preliminary data indicated small increases in the risks of breast cancer, heart attack and stroke in older women using ...
