Selenium levels and recurrent pregnancy loss : is there an association?

Includes abstract.Includes bibliographical references (leaves 58-67).Miscarriage is the commonest complication of pregnancy and affects 12-31% of all conceptions. About 1% of all couples trying to conceive will have recurrent pregnancy loss (RPL). Several causes for RPL have been documented and these include chromosomal abnormalities, peas, thrombophilias and anatomical anomalies such as cervical incompetence. In many couples the aetiology of the pregnancy loss is often not defined but nutritional deficiencies have been postulated as possible causes. In particular selenium deficiency is associated with reproductive failure in animals and, more recently, in some human studies. This study was undertaken to assess the selenium levels in women with RPL without an identified cause
