Recurrent miscarriage is a prevalent reproductive problem that affects many couples who are trying to establish a family. This clinical study will evaluate the effectiveness of intravenous immunoglobulin (IVIG) in improving the live birth rate in couples who suffer from secondary recurrent miscarriage. This study will help in providing an answer to the question of whether IVIG is helpful in secondary recurrent miscarriage.
