In many cases, yes. Varicocele repair is performed to improve the environment within the testicles, which can support better sperm production and function.
Repairing a varicocele may lead to improvements in:
- Sperm count
- Sperm motility (movement)
- Sperm morphology (shape and structure)
For some couples, this may increase the chances of natural conception. For others, it may improve outcomes with fertility treatments such as IVF or ICSI.
That said, outcomes vary. Fertility is rarely about a single factor, and your specialist will guide you on what’s realistic based on your individual profile.
