Carnitine in seminal plasma: its significance in diagnostic andrology.

Carnitine estimation in human semen is of diagnostic value for epididymal function. About 95% of the free carnitine originates from the epididymis. In patients with euspermia the median value of carnitine is 7 +/- 3 mg%.

Glutamic acid concentration in human semen--its origin and significance.

Glutamic acid content of semen was determined photometrically in over 400 semen specimens. Glutamatic acid content was found to increase proportionately to temperature in the first few hours post ejaculation. The glutamate estimation should therefore be performed on semen at 30 min.
