An IVF clinic administers GnRH agonists to patients undergoing ovarian stimulation. Which effect dominates due to pulsatile hormonal regulation?

💡 Explanation

The GnRH agonist initially stimulates LH and FSH release because it mimics GnRH's pulsatile action. This causes a surge before downregulating GnRH receptors, therefore the initial surge is the dominant effect, rather than immediate suppression or direct ovarian hyperstimulation.
