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 (lack of ovulation) or a defective luteal phase are the reasons. In a normal menstruation cycle, i.e. 21 to 35 days, irrespective of the cycle length, ovulation always occurs 12-14 days before bleeding. In other words the luteal phase begins at ovulation and lasts until bleeding occurs. In a defective luteal phase, bleeding occurs before the 12-14 days is up.
