Over the past decade the number of births involving surrogacy with donor eggs and sperm has surged. What, experts wondered, does this mean for the mental and emotional health of the growing number of kids who may or may not know the truth about their distinctive origins?
A team of British researchers, led by Susan Golombok, a professor of family research and director of the Centre for Family Research at the University of Cambridge, has found that children born with the help of a surrogate may have more adjustment problems – at least at age 7 – than those born to their mother via donated eggs and sperm.
Their results, published in the June issue of the Journal of Child Psychology and Psychiatry, suggest that it’s more difficult for youngsters to deal with the idea that they grew in an unrelated woman’s womb, than with the concept that they are not biologically related to one or both parents.
With the number of births involving a surrogate or donated sperm or eggs on the rise, this issue may become increasingly relevant.
The latest statistics from the American Society for Reproductive Medicine (ASRM) show that the number of children who were created with a donated egg rose more than 30 percent from 7,284 in 2004 to 9,541 in 2011, while the number of births involving a surrogate jumped more than 200 percent, from 530 in 2004 to 1,179 in 2011. No one knows how many births have resulted from sperm donations, but estimates range from 30,000 to 60,000 per year, according to a New York Times report.
