Ovulation: What is it?

The eggs are held inside the ovaries. During the first part of each menstrual cycle, the ovary prepares to release an egg.  

Ovulation is the process that occurs once every menstrual cycle during which hormonal changes trigger the release of an egg by an ovary. This happens between day 12 and day 16 before the first day of your next period.  When ovulation is approaching, your body produces a greater amount of a hormone called estrogen that triggers the thickening of the uterus lining and helps create an environment conducive to implantation of a fertilized egg.  

The high level of estrogen triggers the increase of the luteinizing hormone (LH). What we call the LH peek triggers the release of the egg from an ovary: this is ovulation.  Ovulation occurs about 24 to 36 hours after the LH hormone level increases. This is why the LH hormone level is a good indicator of the fertile window.
