Introduction: A study was done comparing controlled ovarian hyperstimulation only with controlled ovarian hyperstimulation with intrauterine insemination. Materiais and Methods: Patients were recruited to the study after completing their basic investigations. They were assigned to Group A (COR only) or Group B (COR with IUI). The treatment groups consisted of unexplained infertility and male factor. Couples were given 3 cycles of treatment, each one being interspersed alternately with a scanned rest cycle. ln Group A couples were instructed to have intercourse for two consecutive days, beginning 24 hours after the hCG injection (treatment). ln Group B, 36 hours after hCG, the male partner produced a sample which was subjected to a routine swim-up preparation which was then used for insemination. Results: The results of the study showed no difference between the two treatment groups. Conclusion: The additional resources needed to carry out intrauterine insemination may not be worthwhile unless patients are carefully selected, in a setting seeking to offer active management for couples on IVF waiting lists.
