[商标/商品名]双氢睾酮注射液
[主要成份]亦称17β－羟基-5α-雄[甾]烷-3-酮、5α－二氢睾酮、5α－DHT、或雄烷酮（stanorone）。
[产品性能]
1、直接或以血清双氢睾酮（DHT）形式使雄激素受体活跃化
2、转化为雌*醇使某些雌激素受体活跃化游离的睾酮会被运送至目标组织细胞的细胞质中，与雄激素受体结合，或被5α-还原酶转为血清双氢睾酮（DHT）。
DHT同样会与雄激素受体结合（这种结合更稳固，DHT的男性激素强度约是睾酮的2.5倍）。
[用法用量]一星期两只
[产品规格]20mg 双氢睾酮
睾酮的影响亦可以自然产生睾酮的时期来区分。在出生后睾酮对男性或女性的不同影响，主要是受着运送游离睾酮的份量及时间所影响。在妊娠后7-12个星期，大部份出生后的男激素效应便会出现.

Dihydrotestosterone (DHT)
(Full name: 5α-Dihydrotestosterone, abbreviating to 5α-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 5α-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.
Significance
DHT is produced by males in utero and is responsible for the formation of male gender specific characteristics. DHT is also an important contributor to other characteristics generally attributed to males, including facial and body hair growth, and deepening of the voice. DHT has been shown to be deactivated in skeletal muscle through the actions of 3-alpha hydroxysteroid dehydrogenase and therefore does not have a significant effect on muscle hypertrophy.
Pathology
It is suspected that DHT is the primary contributing factor in most cases of male-pattern baldness. Women with increased levels of DHT may develop certain androgynous male secondary sex characteristics, including hair above the lip, a deepened voice, and increased muscular growth. DHT also seems to play a role in the development or exacerbation of benign prostatic hyperplasia, or BPH, and prostate cancer, though the exact reason for this is not known.
DHT is also known to participate in the development of acne.
Treatment
The drugs belonging to the group known as 5α-reductase inhibitors are used for treatment of problems stemming from DHT. This group includes finasteride (sold under the names Proscar for BPH and Propecia for androgenic alopecia as well as in generic formulation) and dutasteride (sold under the name Avodart). Currently, DHT supplementation is not used as a treatment for DHT/androgen deficiency.
Alternative treatments used to inhibit DHT include dietary supplementation with, or topically administered preparations of, saw palmetto berry extractives. Unlike most known 5-alpha-reductase inhibitors, saw palmetto induces its effects without interfering with the cellular capacity to secrete PSA. Saw palmetto extract has been demonstrated to inhibit both isoforms of 5-alpha-reductase unlike finesteride which only inhibits the (predominant) type 2 isoenzyme of 5-alpha-reductase.
Also, the chemical equol, derived by consuming foods rich in soy isoflavones by persons with certain digestive-tract bacterial flora, appears to have an androgen-inhibitive effect.
