Is one artificial insemination per cycle with donor sperm as efficacious as two inseminations? Context: To compare pregnancy rates per treatment cycle of artificial inseminations with donor sperm in patients receiving one versus two inseminations. Retrospective cross-sectioned analysis of 167 patients who underwent 869 cycles receiving one or two donor inseminations were reviewed from 1987 through 1993 at our institution. A total of 256 cycles with one donor insemination per cycle resulted in 21 pregnancies and a cycle of fecundity of 8.2%, and 613 cycles with two donor inseminations resulted in 35 pregnancies and a cycle fecundity of 5.7%. Life table and logistic cumulative probability analysis of pregnancy occurrence showed no difference between treatment groups.

These data suggest there are no important clinical differences of cycle fecundity or cure rate in one versus two inseminations with donor sperm. Economic costs of two inseminations may not be justified. Final Decision: yes
