Oocyte and Embryo Transplants
Some women may not be able to produce healthy ova due to ovarian failure or age – related infertility. For these women, oocyte (egg) and embryo donation have been successful. Live birth rates for oocyte and embryo donation range from 25% to 35% (Sauer et al., 1995). An embryo transplant involves artificial insemination of a donor’s ovum with the male partner’s sperm. After fertilization has occurred, the embryo is transferred to the female partner’s uterus. To be successful, it is imperative that fertility drugs be used to synchronize both women’s menstrual cycles. Preliminary research shows that ovum donation offers even higher success rates than natural conception (Remohi et al., 1997).
