Pregnancies after activated oocyte transfer: a new option for infertility treatment.
In this preliminary report, we describe a new technique involving the same-day transfer of activated oocytes to the uterus after intracytoplasmatic sperm injection (ICSI). The technique, termed activated oocyte transfer (AOT), offered to 19 couples, yielded a pregnancy rate per cycle of about 30%, equivalent to traditional in-vitro fertilization (IVF) and ICSI in a laboratory setting. AOT is performed 4 h after oocyte retrieval, permitting the patient to undergo treatment as an out-patient procedure.
