The impact of surgical sperm retrieval on the in vitro fertilization outcomes of infertile patients with a temporary ejaculation failure on their oocyte retrieval day

For patients with temporary ejaculation failure, surgical sperm retrieval compromised the outcomes of fresh embryo transfers, whereas it did not affect the outcomes of thawed embryo transfers.

To evaluate the impact of testicular sperm aspiration on the clinical outcomes of the in vitro fertilization (IVF) patients with temporary ejaculation failure (TEF) on the day of oocyte retrieval.

A case-control study.

University-affiliated IVF center.

One hundred and eight infertile couples encountering TEF on the day of oocyte retrieval.

Testicular sperm aspiration and intracytoplasmic sperm injection (TESA-ICSI) were employed to help the TEF couples to complete their IVF treatments. A group of obstructive azoospermia (OA) patients was chosen as a control group to evaluate the efficiency and safety of this intervention.

Main outcome measure(s):
Fertilization rates, transferable embryo rates and clinical pregnancy rates.

Through the TESA-ICSI, TEF couples achieved a 38.83% (40/103) clinical pregnancy rate (PR) per IVF cycle. Compared with the OA group, the TEF group showed a comparable fertilization rate (66.43% vs. 65.25%), transferable embryo rate (60.76% vs. 60.85%) and PR (51.61% vs. 50.00%) in thawed embryo transfer cycles but a relatively low PR (25.49% vs. 44.64%) in fresh embryo transfer cycles.

TESA-ICSI is a relatively efficient and safe way to help the patients encountering temporary ejaculation failure.
