Ovulation
Updated:Ovulation is the release of a mature egg (ovum) from the ovary. It typically occurs once per menstrual cycle, usually about midway through the cycle. During ovulation, the ovary releases the egg, which then travels down the fallopian tube where it may potentially be fertilized by sperm.
Additional Information
Ovulation is controlled by a complex interplay of hormones, including follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Just before ovulation, there is a surge in LH levels which triggers the release of the egg from the ovarian follicle.
The timing of ovulation can vary between individuals and even from cycle to cycle in the same person. Tracking ovulation is important for those trying to conceive, as the days just before and during ovulation are the most fertile time. Methods to predict or detect ovulation include tracking basal body temperature, monitoring cervical mucus changes, and using ovulation predictor kits that measure LH levels in urine.
Examples
A couple trying to conceive has sex during the woman's ovulation period to increase their chances of pregnancy.
A woman experiences slight abdominal pain or cramping around the time of ovulation, a phenomenon sometimes referred to as "mittelschmerz."
