Clinical outcome after insemination with donor sperm in patients with poor results in ICSI cycles

The introduction of intracytoplasmic sperm injection (ICSI) provided an effective treatment for infertile couples whose infertility was attributed to male factors. However, some of them face poor results after ICSI and subsequently use artificial insemination with donor sperm (AID). Only a few studies have reported on the clinical outcome of AID cycles after previous failed ICSI cycles, with contrasting results. The results reported here involve a cohort of 47 couples undertaking 175 AID cycles after 120 failed ICSI cycles for various reasons. Couples were allocated to two groups according to the availability of top quality embryos (TQE) in ICSI cycles. In our series, AID was successful for couples with and without TQE previously transferred in ICSI cycles, the live birth rate (LBR) per cycle being 20.0% and 13.3%, respectively. However, couples with TQE tended to succeed more rapidly than couples with poor quality embryos, with a higher cumulative LBR (68.0% versus 54.5%, respectively). These findings demonstrate that even couples with a history of unsuccessful ICSI cycles because of poor embryo quality are able to achieve high LBR after AID cycles. However, such couples have a lower cumulative LBR and are required to be more patient to achieve parenthood.
