@A_C_McGregor I mean, this isn’t particularly advanced. It’s just “hypothalamus makes GnRH, pituitary receives GnRH and makes LH, gonads receive LH and make testosterone, testosterone encounters aromatise and turns into oestrogen, hypothalamus notices testosterone and oestrogen and makes less GnRH in response”
A makes B makes C makes D makes less A 🤷🏻♀️
