[Gonadotrophin therapy (author's transl)].

Strict selection of patients is of paramount importance with a view to obtaining optimum results in the treatment of infertile men with gonadotrophins (HMG/HCG). The use of algorithmic tables permits the exclusion of cases of primary orchiopathy, or of genetic or other causes of infertility independent of the endocrine system. Within the scope of a retrospective study this paper gives an account of the results obtained with gonadotrophin therapy in 25 men presenting severe oligozoospermia. The patients had been selected according to the above-mentioned algorithmic schedule, and their serum levels of FSH, LH and testosterone were determined before and after GNRH stimulation. The present study establishes criteria for the selection of such patients as can be treated successfully with gonadotrophin.
