Aetiology of infertility among females seeking treatment at a tertiary care hospital in Sri Lanka.

Aim of this study was to describe the proportion of contributory factors of female infertility in a population that sought fertility treatment. Furthermore, the clinical findings and underlying pathologies associated with ovulatory dysfunction were also sought. A cross-sectional study was carried out at the infertility clinic of the North Colombo Teaching Hospital. New clinic attendees were recruited and both partners had a detailed clinical interview. The women underwent a baseline pelvic ultrasound scan, assessment of ovulation and a hormone profile. Tests for tubal patency were carried out when clinically indicated. Ovulatory dysfunction was noted in 53% (n=218). Clinical and investigatory findings associated with ovulatory dysfunction included irregular menstrual cycles, acanthosis nigricans, hirsutism, polycystic ovary syndrome, a LH:FSH ratio of >1, and increased TSH or testosterone levels. Unilateral tubal occlusion was seen in 9.1 % (n=18) while it was bilateral in 1% (n=2). Abnormalities in sexual function were noted in 10.8% (n=56). Abnormalities in ovulation were common. Clinical findings that could be used to recognise women at risk of ovulatory dysfunction were identified. Abnormalities in sexual function, which are often overlooked in the clinical management of infertility, were seen in over 10% of patients. Tubal factor infertility is rare.
