6.1.6 Conclusions
Current information fits with the hypothesis that in some men the presence of vahcocele is associated with progressive testicular damage from adolescence onwards and consequent reduction in fertility. However, in infertile couples this impaired fertility potential will only be manifest if female fertility is also reduced.
While treatment of varicocele in adolescents may be effective, there is a significant risk of overtreatment. Data from an ongoing study will provide more information in this respect [10].
By the time the couple are aged 30 or over it is probably too late to treat varicocele in the context of infertility because the damage may be far proceeded and thus irreversible. Randomized studies and meta-analysis of randomized studies indicate no fertility benefit from varicocele ligation.
RECOMMANDATIONS
1. Treatment is recommended for adolescents who have progressive failure of testicular development documented by serial clinical examination.
2. Treatment is probably recommendable for adolescents with ipsilateral testicular atrophy. Further clinical studies are needed with long-term follow-up.
3. Treatment may be indicated for adolescents who have varicocele associated with an exaggerated response to releasing factor. Clinical trials are needed.
4. There is no evidence indicating benefit from varicocele treatment in adolescents who have no ipsilateral testicular atrophy and no endocrine abnormalities. In this situation, varicocele treatment cannot be recommended except in the context of clinical trials.
5. Meta-analysis of randomized clinical trials indicates no fertility benefit after varicocele ligation in adults. However, restoration of spermatogenesis has been reported, e.g. in an azoospermic man, proven by pre- and postoperative semen analyses and testicular biopsy [36]. Varicocele ligation for infertility should not be done unless there has been full discussion with the man about the uncertainties of treatment benefit.
6. It may be worth selecting subgroups of men from infertile marriages according to endocrine measurements (e.g. inhibin) for further clinical studies.
7. There is observational evidence that older men with varicocele may have lower testosterone levels than those without, but clinical trials are lacking to address whether varicocele ligation helps in this respect.
