An understanding of the medical causes of infertility is crucial in order to reduce incidences of Infertility and for improving the clinical management of infertility. Although there were much data on infertility in other African countries, no data exist on infertility in Sudan. Seven hundred and ten Sudanese couples were investigated for the infertility in Khartoum Fertility Center, Sudan: 443 (62.4%) had primary infertility and 267 (37.6%) had secondary infertility. The mean (standard deviation) duration of the infertility was 5.2 (4.3) years. A positive male factor alone was found in 257 (36.2%) couples and a female factor in 350 (49.3%) couples: eleven (1.5%) couples had a combination of male and female factors: and the cause of infertility was unexplained in 92 (13.0%) couples. Oligozoospermia and asthenozoospermia were factors responsible for 16.8% and 17.5% of male infertility, respectively. Failure of ovulation (60.3%) was the most common cause of female infertility. The study revealed a high proportion of secondary infertility and a greater contribution of the female factors to infertility.
