Doing some reading and getting hopeful that all will work out:
"In conclusion, varicocele repair is a cost-effective treatment for infertility. Men can upgrade to normal semen, which can allow for a natural pregnancy, or upgrade to semen of adequate quality for intrauterine insemination. Men with azoospermia may produce ejaculated sperm adequate for ICSI. Even if a man remains azoospermic, varicocele repair may enhance spermatogenesis allowing enough sperm production for ICSI. Finally, microsurgical varicocelectomy will improve testosterone levels in a majority of men, which is a men’s health issue aside from infertility."
