A contraceptive pill that could be taken by men as well as women could be on the horizon. 一种男女通用的避孕药即将问世。 A breakthrough in the understanding of the biology of sperm could lead to a unisex version of the Pill, US government-funded scientists said. 由政府资助的美国科学家团队近日宣布，他们在精子生物学领域的研究获得重大突破。以此为基础，他们可以开发出一种男女通用的避孕药。 They have identified a protein in sperm that gives it the energy it needs to power towards the egg and break its way into it. 他们发现，精子中有一种蛋白质负责提供其游向卵子并与之结合所需的能量。 As the researchers put it, the ABHD2 protein allows the tail to ‘crack like a whip’ and ‘power kick’ its way into the egg. 这种名为“ABHD2”的蛋白质能使精子“快马加鞭”，冲向卵子。 |
