Sexual differentiation in humans 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 paramesonephric ducts to regress. Testosterone converts the mesonephric ducts into male accessory structures, including the epididymis, vas deferens, and seminal vesicle. Testosterone will also control the descending of the testes from the abdomen into the scrotum. Many other genes found on other autosomes, including"WT-1", "SOX9", "SF-1" also play a role in gonadal development. Females:
Causes of sexual violence experience an increase in almost all forms of violence, including sexual violence. Many of the factors operating at a national level have an international dimension. Global trends, for instance towards free trade, have been accompanied by an increase in the movement around the world of women and girls for labor, including for sex work. Economic structural adjustment programmes, drawn up by international agencies, have accentuated poverty and unemployment in a number of countries, thereby increasing the likelihood of sexual trafficking and sexual violence, something particularly noted in Central America, the Caribbean and parts of Africa.
