Estrogen is the predominant sex hormone that slows bone loss (even in men). Both estrogen and testosterone help stimulate bone formation (T, especially at puberty). Testosterone may cause an increase in cortical bone thickness in transgender men (however this does not necessarily translate to a greater mechanical stability).
Estradiol is a naturally occurring and bioidentical estrogen, or an agonist of the estrogen receptor, the biological target of estrogens like endogenous estradiol. [10] Due to its estrogenic activity, estradiol has antigonadotropic effects and can inhibit fertility and suppress sex hormone production in both women and men.
Estrogens are the major sex hormones in women, and are responsible for the development and maintenance of feminine secondary sexual characteristics, such as breasts, wide hips, and a feminine pattern of fat distribution. [4] Estrogens act by binding to and activating the estrogen receptor (ER), their biological target in the body. [14]
Estradiol levels with 50 to 100 μg/day transdermal estradiol patches applied to the forearm and to the scrotum in a crossover study in 2 men with prostate cancer. [14] In 35 men treated continuously with one 100 μg/day estradiol patch scrotally, the mean estradiol level was ~500 pg/mL (range ~125–1,200 pg/mL).
At the age of 12, Patrick Mitchell decided to transition into a female, only to change his mind two years later. Uncomfortable in his own skin, the Australian school boy begged his mother to allow ...
Gender-affirming hormone therapy (GAHT), also called hormone replacement therapy (HRT) or transgender hormone therapy, is a form of hormone therapy in which sex hormones and other hormonal medications are administered to transgender or gender nonconforming individuals for the purpose of more closely aligning their secondary sexual characteristics with their gender identity.
In 2023, 23,831 gynecomastia surgeries, reducing breast tissue for men, were performed in the U.S. Experts explain the rise in this procedure and the effect of increasing consciousness of body ...
Estradiol is an estrogen, or an agonist of the estrogen receptors (ERs), the ERα Tooltip estrogen receptor alpha and ERβ Tooltip estrogen receptor beta. [11] It is also an agonist of membrane estrogen receptors (mERs), including the GPER Tooltip G protein-coupled estrogen receptor, G q-mER Tooltip Gq-coupled membrane estrogen receptor, ER-X ...
