If a woman with regular menstrual cycles experiences elevated stress, what happens to GnRH pulsatility?

💡 Explanation

Elevated stress can lead to increased cortisol production, which inhibits GnRH secretion. This results in decreased GnRH pulsatility frequency because the hypothalamic-pituitary-gonadal (HPG) axis is suppressed. Therefore, reduced frequency, rather than increased amplitude or unchanged pulsatility, is the likely outcome.
