← Human Body & HealthA woman using a combined oral contraceptive pill consistently misses doses in the third week of her cycle. Which consequence follows from reduced progestin levels during this time?
A)Endometrial lining thins excessively
B)GnRH secretion is fully suppressed
C)FSH levels surge dramatically
D)Ovulation becomes increasingly likely✓
💡 Explanation
Decreased progestin levels reduce negative feedback on the hypothalamus and pituitary. This stimulates GnRH, LH, and FSH release, because the suppression of these hormones is weakened; therefore, follicular development and potential ovulation become more likely, rather than continued suppression typically seen with consistent progestin.
