Abstract

Varicocele repair (VR) has been a mainstay of treatment for male factor infertility for decades. Many males have varicoceles but identifying those who would benefit most from varicocele repair is challenging. This challenge has become more significant with the advent of assisted reproductive technologies (ART), when patients readily proceed to intrauterine insemination (IUI), in vitro fertilization (IVF), or intracytoplasmic sperm injection (ICSI), even with suboptimal semen parameters. In this chapter, we argue that infertile couples with a male partner having a varicocele will benefit from varicocele repair, prior to proceeding to any form of ART. VR may eliminate the need for ART in some couples, and for those couples who still require ART after VR, repair improves success rates by improving sperm counts and quality and is cost-effective.
