Varicocele Repair for Men Undergoing IVF/ICSI

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.
