By which mechanism do LH and FSH return to baseline levels?
Just after the LH surge, estradiol levels increase, which causes negative feedback on GnRH to stop producing LH and FSH, resulting in the decrease in their levels
LH surge
Negative feedback on gonadotropin-releasing hormone (GnRH) by progesterone
Negative feedback on GnRH by estradiol
Negative feedback on GnRH from testosterone
