Measurement of free amino acids in seminal plasma from fertile and infertile oligozoospermic subjects revealed a quantitative reduction of these molecules in infertile patients. Study of the effect of acidic media on seminal plasma appears to suggest the primary role of free amino acids in the "protection" of spermatozoa in the vagina, and the failure of sperm progression in the female genital tract may be due to a decrease of these molecules in semen of infertile patients.
对可育和不育少精子症患者精液中游离氨基酸的测量显示，不育患者体内这些分子的含量出现了定量减少。对酸性介质对精液影响的研究似乎表明，游离氨基酸在阴道内对精子的“保护”中起主要作用，而不育患者精液中这些分子的减少可能是导致精子在女性生殖道中前进受阻的原因。
