[Usefulness and necessity of the andrologist in assisted reproductions units]

In this issue we make a review of our experience in the management of the sterile men: protocols used for the study of men's sterility, causes and specific treatments, surgical recovery of spermatozoa and screening before IVF or IVF-ICSI. We concluded that with an adequate protocol, it's possible to establish the aetiology of men's infertility in a 78.8% of the cases and it's also possible to initiate a specific treatment in almost a 47.8% of men. Results of specific treatment, with a previous selection of patients, could be better than those of assisted reproduction techniques. Best results are obtained in cases of vaso-vasostomy (vasectomy reversal) and obstruction of ejaculatory duct. It's also needed a study of genetics causes and bad prognostic circumstances in those men whose partner is going on with an IVF or IVF-ICSI cycle.
