In specimens of semen kept at 37 degrees C sperm lose their motility and viability. If kept at 4 degrees C they retain their viability but lose their motility from so-called thermal shock. The best temperature to keep semen in order to preserve sperm motility is 20 degrees C. Loss of motility at 37 degrees C is not entirely prevented by prevention of bacterial contamination with antibiotics.
在37摄氏度保存的精液样本中，精子会丧失活力和生存能力。如果保存在4摄氏度，它们能保持生存能力，但会因所谓的热休克而丧失活力。为保持精子活力，保存精液的最佳温度是20摄氏度。用抗生素防止细菌污染并不能完全阻止精子在37摄氏度时丧失活力。
