The American Society for Reproductive Medicine doesn't track how many women have been given the wrong embryos, said Eleanor Nicoll, a spokeswoman.

美国生育医学学会并不追踪调查过有多少位被植入了错误的胚胎，其发言人埃莉诺尼诰说。

At least half of the group did eventually contact their donor father and some met him, says data released at the American Society for Reproductive Medicine meeting in San Francisco.

这些透露身份的捐精者后代最终有一半联系了自己的捐精者父亲，有些人还与捐精者父亲见了面——数据来源于美国生殖医学协会在旧金山的会议。

Research reported at the annual meeting of the American Society for Reproductive Medicine last week produced two other possible causes: taking anti-depressants and the prolonged use of mobile phones.

美国生殖医学会上周的年会上所报告的研究提出另两种可能的原因：服用抗抑郁药和长期使用移动电话。
