Sex-related patterns in the profiles of human urinary amino acids.
The urinary amino acid profiles of 79 young women and 72 young men were studied with an automated highpressure amino acid analyzer. A nonparametric statistical analysis was applied for detecting profile differences related to sex and other variables. A strong sex-related pattern was confirmed and its power for sex determination was evaluated. For the women, profile differences related to the use of oral contraceptives were also discovered and evaluated. No correlation with the menstrual cycle was detected.
