Abstract:
A sample of 225 men examined at the Infertility Service Unit of this hospital had spermiograms, standardized in accordance with WHO guide lines, and a hormone stimulation test with injection of gonadotropin releasing hormone, thyrotropin releasing hormone, and ACTH. The serum concentrations of the following hormones were assessed: follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin, oestradiol (E), thyroid stimulating hormone, cortisol, 21-desoxycortisol, 17-hydroxypregnenolone, 17-hydroxyprogesterone, dehydroepiandrosterone, dehydroepiandrosteronesulphate, androstenedione, testosterone (T), and dihydrotestosterone. The results of the spermiograms were found to be related to the concentrations of the following hormones: FSH, LH, T, and E. Thyroid and adrenal function in men without signs of endocrinological diseases failed to influence spermatic parameters.
