Measurement of concentrations of fructose, proteins, oxalacetic and pyruvic transaminases in seminal plasma were performed in a group of 20 normal males, 30 to 40 years old, subjected to vasectomy. There were no statistically significant differences among the values obtained before and 6 months after the vasectomy. In consecuence it is concluded that bilateral occlusion of the vas deferens do not modify the androgenic function of the testis, and that certain enzymes like glutamic oxalacetic and pyruvic transminases are not incorporated to the semen by the testis but rather by the prostate and/or by the seminal vesicles.
PIP: Fructose, proteins, and glutamic oxalacetic and pyruvic transaminases (GOT and GPT) were measured in the saminal plasma in a group of 20 normal males, 30-40 years old, subjected to vasectomy. The differences between the values obtained before and 6 months after the vasectomy were statistically insignificant. Therefore, it is concluded that the androgenic function of the testis is unaffected by the bilatera l occlusion of the vas deferens, and that certain enzymes, such as GOT a nd GPT, are incorporated in the semen by the prostate and/or by the seminal vesicles, rather than by the testis. The study reports for the 1st time the average concentrations of GPT in the seminal plasma of normal subjects.
