Background: Infertility is defined as a couple's inability to conceive after a period of twelve months of regular unprotected intercourse. Infertility globally affects approximately 10-15% of couples. This study was carried out to find out the determinants of infertility among infertile couples.
Methods: This is a retrospective review of records of 3231 infertile couples in the Department of Obstetrics and Gynecology, Dhulikhel Hospital from January 1, 2008 to June 30, 2018. A total of 3231 infertile couples were evaluated by reviewing their case history including demographic parameters and investigations performed.
Results: Mean age of female cases seeking infertility treatment was 26.85 (±4.78) years and that of male cases was 29.81±3.18 years. About three quarter (74.7%) of the cases was of primary type. Almost half of infertility cases (48.8%) were having only female factor. Of the female contributory factors, half of them (52.12%) had ovulatory cause. Male factors contributed 23.9% of cases and 22.7% cases had abnormality in semen analysis while 1.2% had other sexual dysfunction. Mixed type of infertility was seen in 26.6% and unexplained factors had contribution of 14.4%.
