What hormones peak right before ovulation occurs?

The ovulatory phase begins with a surge in luteinizing hormone and follicle-stimulating hormone levels. Luteinizing hormone stimulates egg release (ovulation), which usually occurs 16 to 32 hours after the surge begins. The estrogen level decreases during the surge, and the progesterone level starts to increase.

What time of day does estrogen peak?

Ovulation occurs mid-cycle in response to a series of hormonal changes that are set off by a peak in estrogen, occurring any day from day 10 to 17 of the Follicular phase.
