Semen characteristics in pubertal boys. IV. Semen quality and hormone profile.

The biological quality of semen was contrasted with levels of FSH, LH, and testosterone in plasma. The level of FSH rises significantly from azoospermia/cryptozoospermia (3.87 +/- 1.1 mU/ml) to asthenozoospermia (5.73 +/- 2.11 mU/ml). In normospermia, however (4.63 +/- 1.88 mU/ml), the level of FSH decreases in a statistically significant manner and remains at the standard level. Comparing the level of LH to the quality of semen, it rises in a statistically significant manner from azoospermia/cryptozoospermia (6.46 +/- 1.35 mU/ml) to oligozoospermia (9.03 +/- 3.35 mU/ml). The level decreases in a statistically significant manner in normospermia (7.15 +/- 1.69 mU/ml). The level of testosterone shows a progressive linear growth from azoospermia/cryptozoospermia (6.03 +/- 2.09 micrograms/ml) to normospermia (6.55 +/- 2.12 micrograms/ml). The growth is statistically insignificant.

Investigation and results of treatment in male sterility.

The authors present the results of treatment in 6548 cases of male sterility. According to their findings 598 (9.1%) men were ineligible for treatment. The various kinds of therapy resulted in an improvement of semen quality in 51.8% of the cases, 57.0% of the cases being eligible for treatment. The best results were obtained in patients with oligozoospermia, asthenozoospermia and teratozoospermia. The percentage of pregnancies was much lower (8.5%) than the improvement of semen quality.

Plasma testosterone levels before and after stimulation with HCG in anorchism.

The authors present four cases of operatively confirmed anorchism. The plasma levels of testosterone and 11-deoxy-17-ketosteroids and dehydroisoandrosterone in urine were low in all cases. After stimulation with HCG, plasma testosterone levels increased in two cases and did not change in another two. The levels of 11-deoxy-17-ketosteroids and dehydroisoandrosterone in urine did not increase.

Varicocelectomy in patients with azoospermia.

The results of surgical treatment of 33 men with azoospermia and varicocele are presented. Microscopic examination of a testicular biospy revealed the Sertoli-cells-only syndrome in nine subjects while degenerative changes in the seminiferous tubules of one or both testes were present in another six persons. In 15 cases decreased spermatogenesis was noted in the testis on the side ipsilateral to the varicocele. In the remaining three subjects the biopsy revealed active spermatogenesis but with absent spermiogenesis. In all cases the changes were equal or more advanced on the affected side. Improvement of the spermiogram was noted in 12 men (34%) and spermatozoa appeared in the ejaculate within 2 to 14 months after operation. In three spouses four gestations occurred. Only in one case where the spermiogram showed improvement were the degenerative changes present in both testes. In the remainder of subjects demonstrating improvement in semen quality, irreversible changes were absent in at least one testis.
