Abstract
The cryoprotective effects of dimethylsulphoxide, dimethylformamide, and ethylene glycol in definite concentrations of 3.5, 7.0, and 12.0 per cent were compared with glycol action in cryoprotective preservation of human semen. Motility behaviour in response to laboratory stress (due to incubation at + 40 degrees C) as well as respiratory activation quotients for succinate, digitonin, and 2.4-dinitrophenol were used as criteria of assessment. The cryoprotective effect of glycerol was in no single instance surpassed by any of the other compounds, with the concentrations tested.
