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

Capsule:
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.

Abstract:

Objective:
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.

Design:
A case-control study.

Setting:
University-affiliated IVF center.

Patient(s):
One hundred and eight infertile couples encountering TEF on the day of oocyte retrieval.

Intervention(s):
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.

Result(s):
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.

Conclusion(s):
TESA-ICSI is a relatively efficient and safe way to help the patients encountering temporary ejaculation failure.
