Can prolonged pregnancy complicate hypothyroidism?

Abstract

To The Editor: Women with primary hypothyroidism may have either oligo-, or amenorrhea, or menorrhagia. These menstrual changes often result in decreased fertility. If pregnancy does occur there is an increased likelihood for early abortion or premature labor [1]. Post term pregnancies (PP) have not been reported before. However, it has been hypothesized that prolonged pregnancy is a possible complication of hypothyroidism due to some sort of myometriopathy [2].
