← Human Body & HealthWhy does amenorrhea become more likely in the luteal phase due to excessive exercise?
A)Elevated estrogen directly damages follicles
B)LH surge is excessively prolonged
C)Prolactin inhibits GnRH irregularly
D)Energy deficit disrupts pulsatile GnRH✓
💡 Explanation
Amenorrhea in excessive exercise during the luteal phase increases because an energy deficit interferes with the pulsatile release of gonadotropin-releasing hormone (GnRH), therefore impairing normal hormonal cycles, rather than a direct impact from estrogen or LH.
