WebbEndogenous opiates, especially beta-endorphin and dynorphin, also play important roles in regulating the frequency and strength of GnRH secretion. The increased secretion of estrogens from the ovaries, stimulated by LH secretion coupled with maturing Graafian follicles (resulting from the increased FSH secretion) leads to menarche. WebbSome of these enlarge and develop into larger cells called primary oocytes and enter the first meiotic division on the pathway to making gametes by meiosis. This happens between 3 and 8 months of gestation in the human embryo. These 'primary' oocytes become arrested in prophase of the first meiotic division until the female becomes sexually mature.
