[Report from the congress on andrology in Montreal. Diagnosis and treatment of the "andropause"].

As reflected by the proceedings of the recent VIIth International Congress of Andrology in Montreal, Canada, modern andrology takes a wider responsibility for men's health than previously. The area has expanded not only into the fields of basal and clinical endocrinology but also into paediatrics and geriatrics. These changes also put pressure on laboratories of clinical chemistry to provide new and clinically more relevant endocrinological investigations such as lutropin assays which detect the biologically active isoforms, and assays of "bioavailable" testosterone, as well as of inhibin B and anti-Müllerian hormone.
