Thyroid hormones and menstrual cycle function in a longitudinal cohort of premenopausal women.

ABSTRACT:

Background

Previous studies have reported that hyperthyroid and hypothyroid women experience menstrual irregularities more often compared with euthyroid women, but reasons for this are not well-understood and studies on thyroid hormones among euthyroid women are lacking.
