Why does the decline in inhibin B levels during the late luteal phase often lead to increased FSH secretion in women planning pregnancy?

💡 Explanation

Decreasing inhibin B reduces negative feedback on the pituitary gland, because inhibin B normally suppresses FSH secretion. Therefore, FSH secretion increases to stimulate follicular development, rather than being suppressed by high estrogen levels or LH pulses directly.
