HARRISBURG, Pa. A court ruling in Pennsylvania could cause potential sperm and egg donors to have second thoughts. The Pennsylvania Superior Court has ordered a sperm donor to pay child support for twin boys born nearly ten years ago. In its ruling, the court invalidated a verbal agreement apparently reached between the woman and the male sperm donor, saying it had to act in the best interests of the children. An attorney for the sperm donor says he may appeal. An ethicist at the University of Pennsylvania says any sperm donor needs to understand "that their identity could be made known to any child that's produced." The California Cryobank says as many as 200-thousand artificial inseminations are performed every year in the United States. http://www.kesq.com/Global/story.asp?S=2083161 .
