title: Effectiveness of hMG-hCG treatment for DNA/RNA syntheses in subfertile human testis in vitro.
abstract: To evaluate the effect of hMG-hCG treatment on spermatogenic impairment, DNA/RNA syntheses were measured in 25 patients with idiopathic male infertility by estimating the values of 3H-thymidine and 14C-uridine incorporation into the testicular tissue cultured with or without the hormonal treatment. Without the hormonal treatment, the levels of 3H-thymidine incorporation were in inverse correlation with the progress of spermatogenic impairment, whereas disturbances in responsiveness to the hormonal treatment directly correlated with spermatogenic impairment. Although the 14C-uridine incorporation increased both with and without the hormonal treatment, the values showed different patterns from those of 3H-thymidine incorporation. It would appear that the DNA synthesis in testicular tissue cultured with or without hMG-hCG treatment might predict the responsiveness to hormonal treatment for patients with idiopathic male infertility.
