In hormone therapy, trans women often experience slight weight gain as men generally carry higher levels of visceral fat compared to subcutaneous fat, and less fat overall compared to women. Over months and years, HRT causes the body to accumulate new fat in a feminine pattern ( gynoid fat ).
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 ...
Proceptivity and receptivity in the female rat are indicators of sexual motivation, thus indicating a direct relationship between estrogen levels and sexual motivation. In addition, female rats receiving doses of estrogen and progesterone were more likely to exert effort at gaining sexual attention from a male rat. [17]
Early research into the differences between male and female brains showed that male brains are, on average, larger than female brains. This research was frequently cited to support the assertion that women are less intelligent than men. [83] [84] One of the most influential early researchers on this topic was Paul Broca. In 1861, he examined ...

As a female sex hormone, progesterone is more significant in females than in males. During the menstrual cycle, progesterone increases just after the ovulatory phase to inhibit luteinizing hormones, such as oxytocin absorption. [39] In men, increased progesterone has been linked to adolescents with suicidal ideation. [40]
The volumes of sexually dimorphic brain structures in transgender women were found to change and approximate typical female brain structures when exposed to estrogen concomitantly with androgen deprivation over a period of months, [31] suggesting that estrogen and/or androgens have a significant part to play in sex differentiation of the brain ...
Estradiol is a naturally occurring and bioidentical estrogen, or an agonist of the estrogen receptor, the biological target of estrogens like endogenous estradiol. [11] Due to its estrogenic activity, estradiol has antigonadotropic effects and can inhibit fertility and suppress sex hormone production in both women and men.
