Aims and objectives
CONGENITAL HYPOTHYROIDISM, SUBCLINICAL HYPOTHYROIDISM
This study aimed to prospectively determine the thyroid function status of the newborns conceived following OSCM HSG, and establish whether there were any associations between maternal iodine or thyroid hormone levels following the HSG and neonatal thyroid function. The objectives were to determine the incidence of:Subclinical hypothyroidism in the newborn, defined as either: a) mild TSH elevation in the newborn screening (TSH 10–15 mIU/L) from dried blood spot cards (Congenital hypothyroidism, defined as TSH >15 mIU/L from dried blood spot cards in the newborn screening and persistently elevated serum TSH levels or reduced FT4 in subsequent tests, requiring ongoing thyroxine replacement based on the stepwise complex protocol for diagnosis (
