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.
