		This suggests that it is the excess presence of dihydrotestosterone in the scalp tissue that causes androgenetic alopecia in those patients genetically predisposed.
		Testosterone converts to dihydrotestosterone with the aid of the enzyme 5-alpha-reductase, which is held in a hair follicle's oil glands.
		Scientists now believe that the amount of circulating testosterone is the not the problem, but the level of DHT binding to the receptors in the scalp follicles is of immense concern.

		Dihydrotestosterone (DHT) is the androgen that is relevant in androgenic alopecia.
		Dihydrotestosterone is a steroid hormone that binds to androgen receptors to effect genetic transcriptional events (Kaufman 2002).
		Since it is believed that dihydrotestosterone act on the androgen receptors located in the dermal papilla of the hair follicles, cultures of dermal papilla cells were used by Randall, al to determine the responses to DHT and the ability of the androgen receptors to bind to DHT (Randall.

		Dihydrotestosterone by Ray Sahelian, M.D. DHT (dihydrotestosterone) is an androgen from testosterone through the action of the enzyme 5-alpha-reductase.
		Dihydrotestosterone is primarily responsible for the physical changes that occur during male sexual maturation and is thought to be related to sex drive as well as erectile capabilities in men.
		Finasteride inhibits 5alpha-reductase, thereby prohibiting the conversion of testosterone to dihydrotestosterone, which is implicated in the development of hairless in some men.

	Compounded Percutaneous Testosterone Gel: Use And Effects in Hypogonadal Men
		Patients were withdrawn from their previous hormone therapy (where applicable), and baseline laboratory studies were obtained for total testosterone, free testosterone, dihydrotestosterone, estradiol, luteinizing hormone, follicle-stimulating hormone, complete blood counts, lipid panels, and chemistry panels.

		Its activity in the body is that of a pure androgen, and similarly side effects related to estrogen such as increased body fat, water retention and gynecomastia are not possible during use.
		Dihydrotestosterone is further shown to have anti-estrogenic activity, an added benefit when we are looking to lower the activity of this hormone in the body.
		Dihydrotestosterone is also very open to the 3alpha-hydroxysteroid dehydrogenase enzyme, present in large amount in skeletal muscle tissue[v].

		The influence of serum on the uptake, conversion and action of dihydrotestosterone in relation to the sex steroid binding protein, TeBG, has been investigated in rat ventral prostates in organ culture.
		The conversion of dihydrotestosterone to androstanediol followed the same pattern and less androstanediol was formed in the presence of pregnancy serum.
		The effect of the human sera on uptake and conversion was correlated with the androgenic activity of dihydrotestosterone applied at physiological concentrations and expressed as the percentage of secretory columnar cells present.

		Dihydrotestosterone is the resulting product of direct contact between the enzyme 5-alpha-reductase found in the skin and the scalp with the hormone testosterone.
		Dihydrotestosterone binds to receptors sites on the scalp and hair follicles and interrupts and interacts with the normal chain of events involved in continual hair growth.

	Dihydrotestosterone (DHT) conversion
		Dihydrotestosterone, more commonly referred to as DHT, this hormone is in fact measured to be approximately three to four times stronger than testosterone itself.
		Testosterone is converted to dihydrotestosterone upon interaction with the 5-alpha reductase enzyme.
		Acne for example is often triggered by dihydrotestosterone activity in the sebaceous glands, and the local formation of dihydrotestosterone in the scalp is typically the problem that causes male pattern hair loss.

		Dihydrotestosterone (DHT) (Full name: 5Î±-Dihydrotestosterone, abbreviating to 5Î±-DHT; INN: androstanolone) is a biologically active metabolite of the hormone testosterone, formed primarily in the prostate gland, testes, hair follicles, and adrenal glands by the enzyme 5Î±-reductase by means of reducing the 4,5 double-bond.
		Dihydrotestosterone belongs to the class of compounds called androgens, also commonly called androgenic hormones or testoids.
		DHT is thought to be approximately 30 times more potent than testosterone because of increased affinity for the androgen receptor.

		Since everyone has DHT that is produced by their bodies and only some people suffer from hair loss there has to be another factor involved.
		While the precise mechanism which underlies androgenic alopecia is unknown, a high level of dihydrotestosterone (DHT) is crucial in initiating the process.
		DHT is formed from testosterone with the conversion from testosterone to DHT being mediated by 5-alpha reductase.

	Treatment of lichen sclerosus with topical dihydrotestosterone -- Paslin 78 (6): 1046 -- Obstetrics & Gynecology
		Because serum levels of dihydrotestosterone are low in women with vulvar lichen sclerosus and because dihydrotestosterone is an effector androgen in vulvar skin, this double-blind cross-over study assessed five women with vulvar lichen sclerosus to determine the response to treatment with dihydrotestosterone.
		Objective gross and microscopic improvement in lichen sclerosus accompanied sustained treatment with topical dihydrotestosterone, but not with vehicle alone.
		However, there was no change in symptoms (itching and dyspareunia) in these women, although dihydrotestosterone did improve some of the features of vulvar lichen sclerosus and may represent a new treatment for this disease.

		Serum estradiol levels are normal but dihydrotestosterone levels are high in hypogonadal men treated with the scrotal testosterone patch, presumably due to the high rates of 5-alpha reduction of testosterone to dihydrotestosterone during its passage through the scrotal skin.
		Because testosterone effects on the prostate are mediated through its metabolite, dihydrotestosterone, there was initial concern that long-term exposure to high serum dihydrotestosterone levels might have deleterious effects on the prostate.
		Serum dihydrotestosterone to testosterone ratios are higher in hypogonadal men treated with oral testosterone undecanoate, as compared to healthy eugonadal men (340).
