Background:Amino acids can elevate sperm count, motility, and morphology. Increasing the availability
of these amino acids can help to improve male fertility certain foods can help to improve sperm
parameters. This is due to the high concentration of specific amino acids. There are many amino acids
involved in the production, development and maintenance of sperm.
Aims:assessment of seminal plasma free amino acids among fertile men.
Patients and methods: this study done on 50 fertile menassessment of free amino acids in their seminal
plasma, Semen analyses were done and amino acids measured in seminal plasma using H.P.L C.
Results:The median and range of their semen analysis parameters were :volume 2(3-3),liquefaction
time 10(10-15), sperm concentration 60(50-75)million / ml ,total sperm motility80(80-80) %, abnormal
sperm35(30-40),viability 67.5(60-80)%the range of seminal plasma leucine was(1.68-1.87),isoleucine
(1.22-1.31),valine(0.33-0.53)tyrosine, (1.11-1.22),phenylalanine (0.79-0.89) ,histidine (1.28-1.51)
,Tryptophan (0.26-0.36).
Conclusions:Assessment of seminal plasma amino acids is very helpful in evaluation of male fertility.
