1H nuclear magnetic resonance of human seminal plasma in in vitro fertilization attempts: use of automatic spectrum analysis.
Seminal plasma affects the quality of spermatozoa. The possible use of 1H nuclear magnetic resonance (NMR) analysis of human seminal plasma to determine a full biochemical profile that would allow the prediction of successful in vitro fertilization was examined. Two seminal plasma patterns (GI and GII) were found. The main compounds in GI were glycerophosphorylcholine, citrate and lactate, and in GII, choline and amino acids. These patterns did not fit into the usual spermogram classes. However, GI exhibited the higher pregnancy rate, suggesting that the equilibrium established between the components in seminal plasma affected not only the quality of spermatozoa but also embryonic quality.
