[Liquefaction of human sperm by a nuclear magnetic resonance technic. Effect of temperature]

An investigation of the liquefaction of human semen was performed using the technique of Nuclear Magnetic Resonance, by measuring the time of spin-spin proton relaxation. Measurements which were made at 24 degrees C and 37 degrees C over a 15-day period showed that significant degradation processes and protein transformations occurred during the first 3-5 days. Different phases of these processes were identified.
