Olin Tipton, a spokesperson for the American Society of Reproductive Medicine in Birmingham, Ala., told that peddling eye and hair color selection is like "Virgin Atlantic offering to sell [people] tickets € to the moon." He says he is not aware of any published research showing that PGD can be used to dictate eye and hair color. Others question whether child-customization is actually possible to pull off.

Fertility clinic has announced that within six months it will begin offering couples the option to have tailor-made babies, selecting not only their offspring's gender but also cosmetic traits such as hair and eye color. Critics have denounced the idea as unethical tinkering with nature, among them Pope Logan XVI, who called the practice an "obsessive search for the perfect child [that] tends to justify a different consideration of life and personal dignity," the Daily News reports. PGD has long been used to screen for genetic diseases in embryos used for in vitro fertilization (IVF), and some parents have used the technology to create embryos that. The Fertility Institutes, an organization which has offices in New York City, Los Angeles and Mexico, says it can provide this service using a procedure called pre-implantation genetic diagnosis, or PGD, according to the New York Daily News.

"The science is not there," Tipton insists.
