Concerns arise over sperm donors
英语课
Beijing, Sept. 6 (Xinhua) -- A sperm 1 donation scandal disclosed recently has aroused growing concern in the United States.
According to the New York Times' report, Ryan Kramer, the son of a donor 2, found that he has more than 150 half-siblings - they are all the children of the same donor.
"It's wild when we see them all together - they all look alike," said Cynthia Daily, mother of Kramer.
As more women choose to have children on their own, the demand for sperm donors 3 has surged.
Some sperm banks are earning huge profits by allowing too many mothers to receive sperms 4 from the same popular donors, according to the report.
And this trend will lead to risks: rare genetic 5 diseases could be spread more widely, and the children of the same donor could meet and, unbeknownst to them, commit incest, medical experts warned.
Parents and donors are calling for a tighter regulation so that donor children can know more about their donors, and the number of kids from each donor can be limited.
