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).
One of the major signs of anovulation is irregular or absent menstrual periods. For non-pregnant women of a reproductive age (between about ages 15â40), anovulation is abnormal and thought to be the main cause of infertility in about 30 percent of fertility patients.
