Since there are several different types of artificial insemination, each carries with it, different rates for success. Of the primary types of assisted reproductive technologies, the average success rates are:
- intrauterine insemination (fertilization) - fertilization by injection of sperm into the uterus - success rate: up to 90% of couples usually conceive within the first 6 cycles or treatments, making an average success rate of 15% for each treatment
- intra-fallopian insemination - fertilization by injection sperm directly into the fallopian tubes - success rate: average 30%
- in vitro fertilization - fertilization of egg by sperm in a test tube or petri dish - success rate: average 30% success in achieving pregnancy, but once pregnant, the successful live birth rate was an average of 83%
Overall, according to the Centers for Disease Control and Prevention's Assisted Reproductive Technology (ART) Report, the average live birth rate for ART is 36%, which is actually down from previous years. This may represent ART attempts on couples who may have been declined, in earlier years, due to the severity of their infertility problems, or the advanced age of women seeking treatment, since fertility and the ability to carry to term tends to decrease in women over the age of 35.
Additionally, live birth rates vary between frozen and fresh donor sperm and eggs, as well as the prevalence of multiple births, which impacts the ability to carry to term and deliver healthy infants.
