Liquefaction of Human Semen by Spin-Spin Proton Relaxation Technique

Abstract

An investigation of the liquefaction of human semen was performed using a technique of nuclear magnetic resonance, by measuring the time of spin-spin proton relaxation. Measurements made at 24°C over a 15-day period showed that significant degradation processes and protein transformations occurred during the first 5 days. Different phases of these processes were identified.
