Title
Levels of L-carnitine and L-O-acetylcarnitine in normal and infertile human semen: a lower level of L-O-acetylcarnitine in infertile semen
The level of L-carnitine was determined in normal human seminal plasma and sperm. Most of the L-carnitine is concentrated in the seminal plasma and its level is about 10 times higher than that in blood plasma. About 50% of total L-carnitine in normal human seminal plasma exists in the form of acetylcarnitine. Similar studies were also carried out in oligospermic and azoospermic human seminal plasma. The level of L-O-acetylcarnitine in both types of infertile samples is significantly lower than that in normal samples. On the other hand, the level of free L-carnitine is the same in fertile and infertile seminal plasma.
