Diagnosis and treatment of infertility-related male hormonal dysfunction.
Treatment of infertility-related hormonal dysfunction in men requires an understanding of the hormonal basis of spermatogenesis. The best method for accurately determining male androgenization status remains elusive. Treatment of hormonal dysfunction can fall into two categories - empirical and targeted. Empirical therapy refers to experience-based treatment approaches in the absence of an identifiable aetiology. Targeted therapy refers to the correction of a specific underlying hormonal abnormality. However, the tools available for inferring the intratesticular hormonal environment are unreliable. Thus, understanding the limitations of serum hormonal assays is very important for determining male androgen status. Furthermore, bulk seminal parameters are notoriously variable and consequently unreliable for measuring responses to hormonal therapy. In the setting of azoospermia owing to spermatogenic dysfunction, hormonal therapy - relying on truly objective parameters including the return of sperm to the ejaculate or successful surgical sperm retrieval - is a promising treatment. This approach to the treatment of fertility-related hormonal dysfunction in men contrasts with the current state of its counterpart in female reproductive endocrinology. Treatment of male hormonal dysfunction has long emphasized empirical therapy, whereas treatment of the corollary female dysfunction has been directed at specific deficits.
