Contemporary challenges and advanced technologies in the management of subfertile men with varicocele.

Varicocele, closely linked to male fertility, requires urgent and focused research due to many unresolved questions. The absence of clear reference values distinguishing "normal" from "abnormal" semen parameters in the 6th World Health Organization (WHO) laboratory manual significantly complicates diagnosis and treatment. Additionally, the clinical relevance of total progressively motile sperm count (TMSC) remains unclear, leaving practitioners without critical guidance. The decision to perform varicocelectomy, particularly in cases of isolated teratozoospermia, is fraught with uncertainty. Furthermore, the best treatment strategy for those experiencing subfertility after varicocele surgery is still undetermined, adding another layer of complexity. These pressing issues, along with contentious debates surrounding isolated teratozoospermia treatment, highlight the need for large-scale multicenter randomized clinical trials. Such studies are essential to fully understand varicocele's impact on male fertility and to develop evidence-based management protocols.
