Abstract
In view of evidence indicating a correlation between thyroidal
activity and maturation in mammals, a series of experiments was designed
to investigate the relation of thyroxine (T4) and triiodothyronine (T3)
on the onset of puberty in female rats. Five experiments measuring
circulating levels of T3 and T4 throughout the pubertal period and
studying the age of sexual maturation as a result of prepubertal
hypothyroidism and hyperthyroidism were conducted. The results indicated
delayed sexual development as a result of increased levels of T3 and T4
and premature puberty as a result of thyroidectomy. The mechanisms by
which the thyroid functions in controlling puberty remain unclear, calling
for further investigation.
