Abstract: Thyroid disorders both hypo and hyperthyroidism are frequently seen in women, the incidence of hypothyroidism is being much higher than hyperthyroidism. Reported studies in these two conditions on reproductive physiology in women and in experimental female animals have shown that both hypo and hyperthyroidism are associated with delay in onset of puberty, anovulation, various menstrual irregularities, infertility and spontaneous abortions. The present study conducted on the levels of FSH, LH and Prolactin in 36 women subjects between the age group 18 – 35 years out of which 10 are control, 26 are with thyroid disorders. In this 26 thyroid disorder patients 16 are hypothyroid cases and 10 are hyperthyroid cases. The result of the present study indicates that there is significant (>0.001) increased basal levels of serum LH as compared to FSH. Thus the ratio of LH: FSH altered from 1:1 to 6:1, and also there is significant (>0.001) increase in serum prolactin levels in hypothyroidism, where as no change in hyperthyroidism seen.
