5-DHT or DHT is a male reproductive hormone that targets the prostate gland, bulbourethral gland, seminal vesicles, penis and scrotum and promotes growth/mitosis/cell maturation and differentiation. Testosterone is converted to 5-DHT by 5alpha-reductase, usually with in the target tissues of 5-DHT because of the need for high concentrations of ...
The effect of estrogen on the immune system is in general described as Th2 favoring, rather than suppressive, as is the case of the effect of male sex hormone - testosterone. [89] Indeed, women respond better to vaccines , infections and are generally less likely to develop cancer , the tradeoff of this is that they are more likely to develop ...
Sex hormones, also known as sex steroids, gonadocorticoids and gonadal steroids, are steroid hormones that interact with vertebrate steroid hormone receptors. [1] The sex hormones include the androgens , estrogens , and progestogens .

The gradual growth in sex difference throughout a person's life is a product of various hormones. Testosterone is the major active hormone in male development while estrogen is the dominant female hormone. These hormones are not, however, limited to each sex. Both males and females have both testosterone and estrogen. [107]
[7] [26] Receptors for prolactin and other hormones including insulin-like growth factor 1, insulin-like growth factor 2, luteinizing hormone, progesterone, and human chorionic gonadotropin have been found in male breast tissue, but the impact of these various hormones on gynecomastia development is not well understood.
[28] [56] [57] [51] Almost all combined birth control pills contain the potently liver-active estrogen ethinylestradiol, and the typical doses of ethinylestradiol present in combined birth control pills increase sex hormone-binding globulin (SHBG) levels by 2- to 4-fold and consequently decrease free testosterone levels by 40 to 80%. [58]
Male development can only occur when the fetal testis secretes key hormones at a critical period in early gestation. The testes begin to secrete three hormones that influence the male internal and external genitalia: they secrete anti-Müllerian hormone (AMH), testosterone, and dihydrotestosterone (DHT). Anti-Müllerian hormone causes the ...
