THE VALUE OF SINGLE VERSUS REPEATED INSEMINATION IN INTRAUTERINE DONOR INSEMINATION CYCLES

Pregnancy rates per cycle of intra-uterine donor insemination followin g 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 1 5 women became pregnant (pregnancy rate = 22%). Of 65 cycles in which repeated insemination was performed, 16 women became pregnant (pregnan cy rate = 25%). This difference in pregnancy rates was not statistical ly significant (chi(2) = 3.6, P = 0.84). We conclude that cycle fecund ity may not be increased by repeating insemination.
