The inhibitory effect of Old Coke, caffeine-free New Coke, New Coke, Diet Coke and Pepsi-Cola on human sperm motility was studied with a trans-membrane migration method. None of them could decrease sperm motility to less than 70% of control within one hour. A previous study which claimed a marked variation of spermicidal potencies among different formulations of Coca-Cola could not be confirmed. Even if cola has a spermicidal effect, its potency is relatively weak as compared with other well-known spermicidal agents.
采用跨膜迁移法研究了原味可乐、无咖啡因新可乐、新可乐、健怡可乐和百事可乐对人类精子活力的抑制作用。在一小时内，它们均无法使精子活力降低至对照的70%以下。之前一项声称可口可乐不同配方的杀精效力存在显著差异的研究未能得到证实。即便可乐有杀精作用，与其他知名杀精剂相比，其效力也相对较弱。
