| Popis: | We have previously shown that LHRH agonist [D-Trp6,Pro9-NEt]LHRH (LHRHA) results in reversible oligozoospermia when given to normal subjects for up to ten weeks. A fall in plasma testosterone was accompanied by loss of libido and potency. We now report six subjects who were evaluated by semen analysis and hormone profile at two-week intervals during ten-week basal, 20-week treatment, and post-treatment periods lasting at least ten weeks. Treatment consisted of LHRHA (50 microgram subcutaneously daily), and testosterone enanthate (100 mg intramuscularly every two weeks). Sperm density (mean basal 76.7 +/- 8.7 x 10(6)/ml) fell consistently in each subject to a mean nadir of 12.3 +/- 4.5 x 10(6)/ml (p less than 0.001). This is similar to the mean nadir of 11.6 +/- 5.8 x 10(6)/ml achieved when LHRHA was given alone. In each individual subject, sperm density returned to his basal level after cessation of treatment. No consistent changes were seen in sperm motility of morphology, or in semen volume. Libido and potency were maintained in all subjects. An additional three subjects received testosterone enanthate alone in identical dosage for 20 weeks. No change in sperm density was observed. In contrast to treatment with LHRHA alone, combination treatment produces reversible oligozoospermia without attendant change in potency. |
