Abstract

PURPOSE: In order To investigate the effects of the pituitary and sex hormones in seminal plasma on male infertility, LH, FSH, prolactine, and testosterone were measured in blood and seminal plasma in infertile men, men who had undergone vasectomy, and a control group. The findings were studied in relation to semen analysis in these subjects.
RESULTS
1. The FSH concentration in blood plasma was lower in the control group than in infertile subjects (p<0.05). 2. The testosterone concentration in seminal plasma was significantly lower in the vasectomy and infertility groups than in the control group (p<0.05). Among the infertile men, the testosterone concentration in the seminal plasma was lower in azospermic than tn normospermic and oligospermic subjects (p<0.01). 3. LH, FSH, prolactin and testosterone concentrations in the control group were significantly lower in the seminal plasma than in the blood plasma (p<0.01). There was no relation between hormone concentration in the seminal plasma and that in the blood plasma (p<0.05).
CONCLUSION
Testosterone concentration in seminal plasma is low but nevertheless, may have an effect, not only on sperm density, but also on sperm function and survival. This value can be utilized as a diagnostic marker in the infertile man with serum FSH-related inadequate spermatogenesis.
