According to a recent study, babies that are born full-term, but conceived through fertility drugs, tend to be slightly shorter when they grow up than those that are naturally conceived. The study, however, assures that the overall physical health of such babies is not compromised throughout their life term. Researcher Tim Savage, MD, paediatrician and research follow at The Liggins Institute, University of Auckland, New Zealand, reassuringly said that such babies remained within their normal height and weight range for their age and sex. The research focused on determining whether there was a difference in the height of children born to a mother, who used fertility drugs, such as clompiphene, without the help of in vitro fertilisation.
The research team studied 84 children, who were conceived through fertility drugs alone and about 258 children, who were conceived naturally. It was found that the fertility drug-conceived children were 2 cm shorter considering their age and sex than children conceived naturally. When the groups were studied by their sex, the height difference was seen to be more distinct in boys compared with girls.
