What is Ovulation?
Ovulation refers to a specific phase in your menstrual cycle. Known as the ovulatory phase, it is during this time that your body releases an egg for fertilization. During the ovulatory phase, your body sends a series of signals that trigger an increase in the levels of estrogen in your body. In turn, this increase sets off a rise in luteinizing hormone (called the LH surge), a special hormone that helps you ovulate. When this LH surge reaches a certain point, one of your ovaries releases an egg. This egg will then travel down the fallopian tubes in order to be fertilized.
