Pulmonary surfactant, secreted via exocytosis of lamellar bodies (LB) by alveolar type II (AT II) cells, maintains low alveolar surface tension and is therefore essential for normal lung function.
This in turn causes abnormalities in the levels of the other hormones, Estrogen and Progesterone, thus adding to the chemical turmoil in the body. The common causes of Anovulatory Cycles include: Polycystic Ovarian Disease (PCOD). Hyperprolactinaemia (increased blood levels of the hormone Prolactin).
Anovulation is when the ovaries do not release an oocyte during a menstrual cycle. Therefore, ovulation does not take place. However, a woman who does not ovulate at each menstrual cycle is not necessarily going through menopause. Chronic anovulation is a common cause of infertility.
