What are the phases of ovulation?
The entire ovulation phase is actually defined by a period of elevated hormones during the menstrual cycle. The process itself can be informally divided into three phases: 1. Periovulatory (follicular phase): A layer of cells around the ovum begins to mucify (become more mucous-like) and expand, and the uterus lining begins to thicken. 2. Ovulatory (ovulation phase): Enzymes are secreted and form a hole (or stigma) that the ovum and its network of cells use to exit the follicle and eventually enter the fallopian tube. This is the period of fertility and usually lasts from 24 to 48 hours. 3. Postovulatory (luteal phase): A hormone called LH or luteinizing hormone is secreted. A fertilized egg will be implanted into the womb, while an unfertilized egg slowly stops producing hormones. In addition, the lining of the uterus begins to break down and prepares to exit the body during menses.
