Plasma Gonadotrophic Hormones, Testicular Biopsy and Seminal Analysis in the Men of Infertile Marriages

Abstract

The first step in the investigation of infertile men is to obtain 2 seminal analyses 3 days after the previous ejaculation. Clinical assessment of testicular size is an unreliable means of assessing spermatogenesis and is best done by performing bilateral testicular biopsies. Azoospermic men with grossly elevated FSH levels should be advised to consider AID or adoption. Those with normal or mildly elevated FSH levels should undergo testicular exploration in an attempt to correct an obstructive lesion. Azoospermic men with subnormal FSH levels may have an isolated hormone defect which will respond to treatment with Pergonal. Different treatment programmes for oligozoospermic men depending on the results of the FSH and LH assays may lead to a more rational approach to therapy. Infertility associated with varicocele may possibly be associated with a local disturbance of "inhibin" and FSH concentrations.
