In a study of children whose parents had history of thyroid disease, Carey et al.(39) found a 24% prevalence of thyroid "abnormalities", including a prevalence of 6.9% abnormal thyroids, and 9.3% with positive TG Ab measured by hemagglutination assay (TGHA) and 7.8% positive MCHA assays

However, the study is limited by its 12-month follow-up period, thereby restricting the observation of potential long-term side effects associated with oral estrogen therapy beyond this timeframe
