From Today.com, a research study found that kids born through donor egg/sperm showed no difference in behavior issues as those conceived naturally:
For the study, Golombok and her colleagues followed 30 surrogacy families, 31 egg donation families, 35 sperm donation families and 53 natural conception families until the children were 10 years old. The researchers surveyed the moms when the children were ages 3, 7 and 10 to get an idea of how well-adjusted the youngsters were.
“Signs of adjustment problems could be behavior problems, such as aggressive or antisocial behavior, or emotional problems, such as anxiety or depression,” Golombok says.
There was no difference between children born through egg and sperm donation or children conceived naturally in terms of behavioral adjustment, the researchers found.
