About

For infertile men undergoing intracytoplasmic sperm injection (ICSI), data from retrospective studies suggested that varicocele repair may be beneficial and associated with improved livebirth and pregnancy rates, however, its role remains uncertain and disputed. To date, the investigators are not aware of published randomized controlled trail (RCT) that have evaluated whether varicocele repair would improve ICSI outcomes on patients with male-factor infertility.

Full description

Varicocele repair in the era of assisted reproductive technology (ART) has been a point of dispute. The American Society for Reproductive Medicine (ASRM) Practice Committee recommended has considered ART as a primary treatment for female factor, regardless of the presence of varicocele and abnormal semen parameters.

A systematic review of 7 studies involving 1,241 men with a clinical varicocele and abnormal semen parameters showed improved livebirth and pregnancy rates after varicocelectomy in infertile men undergoing IVF/ICSI. Studies included in this systematic review were retrospective nature with a considerable heterogeneity. Evidence to support varicocelectomy for men with abnormal semen analysis undergoing IVF/ICSI has therefore remained inconclusive.

Exclusion criteria

  1. Patients who willing to undergo ICSI with preimplantation genetic diagnosis.
