Getting vaccinated against Covid-19 won’t affect a couple’s chances of getting pregnant, but contracting the coronavirus could impair male fertility.

接种新冠疫苗不会影响一对夫妇的受孕几率，但是感染新冠病毒可能会损害男性的生育能力。

Those are the main conclusions of a study funded by the National Institutes of Health, refuting a common myth about the vaccine and sending a warning to men who avoid it.
这个结论来自于美国国家卫生研究院资助的一项研究，该研究驳斥了关于疫苗的普遍误解，并向拒绝接种疫苗的男性发出提醒。

Researchers at Boston University studied more than 2,000 couples and found no differences in their chances of conception if either partner was vaccinated compared to unvaccinated couples.
波士顿大学的研究人员对2000多对夫妇进行了研究，发现与未接种疫苗的夫妇相比，接种疫苗的夫妇受孕的几率没有差异。

But the couples’ chances of conceiving decreased slightly if the male partner had contracted the virus 60 days or less before a menstrual cycle, an indication of diminished male fertility.
但是，如果男性伴侣在女性月经周期前60天内或更短时间内感染了新冠病毒，夫妇的受孕几率会略有下降，这表明男性伴侣生育能力有所下降。

One possible reason for that, researchers theorized, is the likelihood that coronavirus infection would cause a fever, which has been known to reduce sperm count.
研究人员推测，一个可能原因是感染新冠病毒可能会导致发烧，而众所周知，发烧会减少精子数量。
