Y. Khalifa et al., THE VALUE OF SINGLE VERSUS REPEATED INSEMINATION IN INTRAUTERINE DONOR INSEMINATION CYCLES, Human reproduction, 10(1), 1995, pp. 153-154
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.
