Background: Hypothyroidism is associated with a wide spectrum of reproductive disorders ranging from abnormal sexual development, menstrual irregularities, and infertility. The present study was conducted to assess thyroid disorders and menstrual disorders in reproductive age group.

Materials and Methods: 84 women in reproductive age group 15-45 years were divided patients into 2 groups of 42 each. Group I was with menstrual disorders and group II with other than menstrual disorders. Parameters such as parity, age of menarche, general physical examination along with pelvic examination was carried out in women with menstrual complaints. Routine investigation like Hb, Platelet count, TLC, DLC, ESR, ABO-Rh, and thyroid profile that includes T3, T4, TSH etc. was recorded.

Results: Age group 15-25 years had 22, 25-35 years had 36 and 35-45 years had 26 patients. Thyroid status was euthyroid seen in 58% in group I and 78% in group II, subclinical hypothyroid in 18% in group I and 10% in group II, overt hypothyroid seen in 16% in group I and 7% in group II, subclinical hyperthyroid in 4%in group I and 1% in group II and overt hyperthyroid in 8% in group I and 4% in group II respectively. There were 2 cases of Amenorrhea, 8 of Hypo/ Oligomenorrhea, 7 of Metrorrhagia, 22 of Menorrhagia and 3 of Polymenorrhea. Among 2 Amenorrhea patients, each had subclinical hypothyroid and overt hypothyroid. Among 8 cases of Hypo/ Oligomenorrhea, euthyroid, subclinical hypothyroid, overt hypothyroid and subclinical hyperthyroid were seen in 3, 2, 2 and 1 respectively. Among 7 of Metrorrhagia, 2 had euthyroid, 1 had overt hypothyroid, 1 had subclinical hyperthyroid and 2 had overt hyperthyroid. Among 22 cases of Menorrhagia, euthyroid, subclinical hypothyroid, overt hypothyroid, subclinical hyperthyroid and overt hyperthyroid was seen in 18,3,1, 0 and 1 respectively. Among 3 cases of Polymenorrhea, euthyroid, subclinical hypothyroid, overt hypothyroid was seen in 1, 1 and 1 respectively.

Conclusion: There was a strong correlation of thyroid dysfunction with menstrual disorders.
