Menstrual cycle (ovarian cycle): It is a series of cyclic changes that occur in the reproductive tract of human females and other primates with a periodicity of 28 days, right from menarche to menopause. It is characterized by menses or loss of blood for a few days. The given chart depicts menstrual cycle. Here,

• A (6-15 days) - Regeneration of endometrium occurs.
• B (16-25 days) - Endometrium thickens, becomes vascularized ready to receive and implant embryo.
• C (26-28 days if the ovum is not fertilized) - Endometrium will degenerate.
