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).
INTRODUCTION. Anovulation is the failure of the ovary to release ova over a period of time generally exceeding 3 months. The normal functioning ovary releases one ovum every 25â28 days. This average time between ovulation events is variable, especially during puberty and the perimenopause period. For nonpregnant women aged 16â40 anovulation is considered abnormal and a cause of infertility in 30% of fertility patients. One of the cardinal signs of anovulation is irregular or absent menstrual periods.
