Gonadal development - starts by 10 weeks’ gestation, almost complete by age 3 months in the male
Without significant input from gonadotropins, although placental hCG plays a role in migration of germ cells and differentiation of Leydig’s cells
By the 21st week of gestation, the hypothalamus secretes GnRH, and the anterior pituitary releases FSH and LH
Their levels reach a peak by the 23rd to 24th week of gestation, which coincides with oocyte maturation in utero, incl. the development of primary follicles.
