[Intrauterine insemination with donor semen. Treatment of involuntary childlessness caused by male infertility].

Intrauterine insemination with cryopreserved donor semen was performed in 114 women in a total of menstrual 381 cycles during the period 1.2.1991 to 15.5.1993. Eighty-one pregnancies were recorded corresponding to a conception rate of 21% per insemination cycle. After ten cycles the probability of conception and expected delivery was respectively 96% and 86%. The results show that intrauterine insemination with donor semen is a good treatment for couples with male infertility. Ultrasonic measurement of the follicles and timing of hCG injection were used for optimal timing of intrauterine donor insemination. The quality of the semen used for insemination is important. It is recommended to inseminate with at least two million of spermatozoa where at least 20% have normal motility.
