[Sino-bronchial infections and male sterility. Presentation of a new variant]

The association of repeated sinus-bronchial-pulmonary infection and male infertility is well known in the literature in conditions such as cystic fibrosis, immotile cilia syndrome and Young's syndrome. Outside the context of these clinical entities, however, the association is unusual. We report the case of a 36-year-old man with sinusitis, bronchiectasis and sterility due to Sertoli-cell-only syndrome, an association that has not been described to date. Testicular biopsy showed absence of spermatogones and other germ cells, and non specific alterations were found in nasal cilia axonemes, in the presence of DNA branches. A sweat test was negative. Given that recent studies have shown an increase in the prevalence os Sertoli-cell-only syndrome, other cases might be described and this association may correspond to a specific entity.
