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.
射精后30分钟对人精浆中的游离氨基酸含量进行了研究。丝氨酸、苏氨酸和酪氨酸是主要氨基酸。对四种男性科诊断的氨基酸浓度比较表明，某些氨基酸与精子之间存在联系。
