Reproductive health in patients with beta-thalassemia.
Homozygous transfusion-dependent beta-thalassemia patients manifest cardiac, hepatic, endocrine, and metabolic disorders attributable to chronic anoxia and iron overload. Short stature, delayed sexual maturation, diabetes mellitus, hypothyroidism, hypoparathyroidism, and metabolic bone disease can and should be diagnosed as early as possible so that the intervention can be fruitful. Primary or secondary amenorrhea is due primarily to pituitary gonadotrope hemosiderosis, as attested by pathology data and the demonstration in vivo of nonstimulable follicle-stimulating hormone and luteinizing hormone release and secretion after the exogenous administration of gonadotropin-releasing hormone or its agonistic analogs. Ovulation can be achieved with the use of exogenous gonadotropins provided that the ovary has no siderosis (as seen in neglected patients) or damage induced by drugs used for bone marrow transplantation. Once pregnancy is achieved, it should be considered high risk and be dealt with or cared for by an expert team to ensure a successful outcome.
