Transgender hormone therapy (male-to-female) rare cases of liver damage and lung disease however. Nonsteroidal antiandrogens like bicalutamide may be a particularly favorable option for transgender women who wish to preserve sex drive, sexual function, and/or fertility, relative to antiandrogens that suppress testosterone levels and can greatly disrupt these functions like cyproterone acetate and GnRH modulators. GnRH modulators are powerful antigonadotropins and hence functional antiandrogens. In both males and females, gonadotropin-releasing hormone (GnRH) is produced in the hypothalamus and induces the secretion of the gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. The gonadotropins signal the gonads to make sex hormones
Transgender hormone therapy (female-to-male) to produce LH (luteinizing hormone) and FSH (follicle-stimulating hormone) which in turn cause the gonads to produce sex steroids. In adolescents of either sex with relevant indicators, GnRH analogues, such as leuprorelin can be used to suspend the advance of sex steroid induced, inappropriate pubertal changes for a period without inducing any changes in the gender-appropriate direction. GnRH analogues work by initially over stimulating the pituitary then rapidly desensitizing it to the effects of GnRH. Over a period of weeks, gonadal androgen production is greatly reduced. There is considerable controversy over the earliest age, and for how long it is
