Pregnancy rates per cycle of intra-uterine donor insemination following ovulation induction were compared retrospectively for those patients having a single, and those having repeated insemination using frozen donor semen. Single insemination was performed in 69 cycles in which 15 women became pregnant (pregnancy rate = 22%). Of 65 cycles in which repeated insemination was performed, 16 women became pregnant (pregnancy rate = 25%). This difference in pregnancy rates was not statistically significant (x2 = 3.6, P = 0.84). We conclude that cycle fecundity may not be increased by repeating insemination.
