title: Free amino-acid composition of human seminal plasma in different andrological diagnoses.
abstract: The free amino acid content of human seminal plasma was studied 30 min after ejaculation. Serine, threonine and tyrosine were the principal amino acids. A comparison of the amino acid concentration of four andrological diagnoses indicates that there was a connection between certain amino acids and spermatozoa.
