Varicocele fertility. It can take up to 9 months after varicocele repair to demonstrate improved semen parameters. Most pregnancies occur 6-12 months after varicocele repair. Unfortunately, just having the surgery does not guarantee that the problem was corrected. It is always best to have varicoceles corrected by a fellowship trained male infertility specialist.
Depends. Unless the varicocele is significant, surgery has not been demonstrated to have a significant effect on fertility. Patients with a more severe varicocele are more likely to benefit from surgery, but even them may not benefit as the cause of the low sperm count may not be the varicocele itself! usually it takes 2-3 months for sperm to form, so 3-4 months at least to start seeing the effect.
