Success rate and pregnancy outcomes of donor insemination
An overall live birth rate of about 11% per cycle should be expected with a multiple pregnancy rate of about 7%. The success rate varies between infertility clinics from 2% to 20%. The live birth rate for donor insemination treatment in the UK was 13% for stimulated cycle and 11% for non stimulated cycle and the multiple pregnancy rate was around 8% (HFEA 2018 report)
As expected younger women had higher success rates than older women and decreases to zero for women over 43. For women under 35, the live birth rate was 16% for stimulated cycles vs 14% for non stimulated cycle. (HFEA patient’s guide 2018). The progress and outcome of pregnancies conceived with donor inseminations are no different from those achieved from sexual intercourse with the same risks of miscarriage and birth defects.
If the couple is lucky and a live birth follows donor insemination they may wish to have a brother or a sister to their baby. In this case, clinics must be contacted sooner than later to save some donor sperm to be used for a second time round, but this is not always possible.
