[Etiologic evaluation of oligo-astheno-teratospermia].

The numerous etiological factors of male hypofertilities and the lack of precision relating to physiopathological mechanisms explain the weak therapeutic armamentarium. It is therefore absolutely necessary to perform a clinical, biological and paraclinical evaluation, logical and standardized, in order to determine etiology which can be cured and attempt a prognosis. The interview, the clinical examination and the sperm count represent the basis from which additional explorations (hormonal assays, biochemistry of the semen, immunological work-up, caryotype, paraclinical examinations) may be requested and provide more specific data.
