Abstract     Introduction: Thyroid dysfunction can affect fertility in various ways resulting in anovulatory cycles, luteal phase defect, high prolactin (PRL) levels, and sex hormone imbalances. Aims and Objectives: To study Ovulation in relationship to thyroid status in the Patients of Infertility. Material and Methods: The present study was conducted in the Department of Obstetrics and Gynaecology, SMGS Hospital, Government Medical College, Jammu for a period of one year . Study Group: Fifty (50) cases of infertile women, in the age group of 20 to 35 years, were selected from outpatient department and indoor. Control Group: Fifty (50) cases of non-pregnant women with proven fertility, in the age group of 20 to 35 years, were selected for control group. Result: In study group, subclinical hypothyroidism was present in 11 (22%) cases, clinical hypothyroidism was present in 2 (4%) cases and subclinical hyperthyroidism was present in 1 (2%) cases. In control group, only subclinical hypothyroidism was present in 2 (4%) cases. among euthyroid group, 26 (72.22%) cases had ovulatory cycles, while 10 (27.78%) cases had anovulatory cycles. In hypothyroid group, 5 (38.46%) cases had ovulatory cycles, while 8 (61.54%) cases had anovulatory cycles. Conclusion: Again in anovulatory infertility, thyroid dysfunction was more common as compared to those with ovulatory infertility. So we conclude that thyroid profile should be done as a routine in infertile women especially when infertility is associated with menstrual disturbances and anovulatory cycles.
