Anovulatory cycle Anovulatory cycle The anovulatory cycle is a menstrual cycle characterized by varying degrees of menstrual intervals and the absence of ovulation and a luteal phase. In the absence of ovulation, there will be infertility. While the normal menstrual cycle in the human typically lasts 4 weeks (28 days, range 24–35 days) and consists of a follicular phase, ovulation, and a luteal phase, followed by either menstruation or pregnancy, the anovulatory cycle has cycle lengths of varying degrees. In many circumstances, menstrual intervals are prolonged exceeding 35 days leading to oligomenorrhea (cycle >35 – 180 days interval), or even longer, amenorrhea.
Centre for Menstrual Cycle and Ovulation Research stated vision was to 'reframe scientific knowledge of the menstrual cycle and ovulation in a woman-centered context.' CeMCOR is now located at Vancouver General Hospital in the Gordon and Leslie Diamond Health Care Centre. Staff includes 15 clinicians and 9 trainees. It is guided by both a Community Advisory Council and a Scientific Advisory Council composed of endocrinologists, epidemiologists, gynecologists, nutritionists, psychologists, and sociologists. CeMCOR published over 50 scientific papers in its first 10 years, as well as 4 books.
