title: [Medical optimisation of sperm retrieval in non obstructive azoospermia].
abstract: Medical optimisation of sperm retrieval in non-obstructive azoospermia is reviewed. Gonadotropin treatment of hypogonadotropic hypogonadism allows obtaining sperms in the ejaculate in about 90% of cases provided the duration of treatment was long enough. TESE is indicated in case of persistent azoospermia at 2 years of continuous treatment. Some publications reported a possible effect of hormonal treatments (FSH, hCG, anti-estrogens, aromatase inhibitors) in primary spermatogenic failure, but mainly in cases selected for their favourable histology and normal hormonal levels. The effect on unselected cases remains doubtful. Conversely, the effect of the treatment of varicoceles is significant. Other medical treatments or advises need further investigations.
