Intrauterine insemination with controlled ovarian stimulation for treatment of infertility: An audit of a new IUI programme in a low resource setting

Abstract

SummaryThis study is an audit of a new intrauterine insemination (IUI) programme in a low resource private fertility practice in southeast Nigeria. IUI was performed using a Wallace flexible catheter 1 day before or on the day of ovulation after ovarian stimulation with clomiphene citrate. The 18 couples treated had either male (16) or unexplained (2) infertility. The women were between 25 and 49 years and 13 (72.2%) of the couples had primary infertility while the duration of infertility ranged from 3 to 15 years. All the women had tubal patency confirmed by laparoscopy and dye test before undergoing IUI. The pregnancy rates per couple and per insemination cycle and the effect of maternal age and source of semen (partner or donor) were determined. The 18 couples had a total of 48 treatment cycles and five became pregnant (confirmed by early ultrasound scan) giving a pregnancy rate of 27.8% per couple or 10.4% per treatment cycle. The pregnancy rate was 41.7% per couple, 15.6% per treatment cycle for the donor group and 0% for the partner group (p < 0.01). Poor sperm quality was responsible for the poor pregnancy outcome in the partner group. The pregnancy rate per couple was 36.5% in women < 35 years compared with 14.3% in those ≥ 35 years (p = 0.02). Similarly, the cycle pregnancy rate was significantly higher in women < 35 years (16.0% vs 4.4%; p < 0.02). There was one (20%) case of twin pregnancy and no miscarriage. Four of the women had a live birth (80%) at term and one had an intrauterine death following severe pre-eclampsia at 29 weeks' gestation. In conclusion, the overall couple and cycle pregnancy rates at our centre is comparable with the rates in many centres. Younger age and good quality semen are good indicators of a successful outcome. Infertile couples should therefore be evaluated early and recommended for this treatment option before advanced female age.
