Attention Clomid users: Study finds children may be shorter

Many couples who are struggling with becoming pregnant opt for fertility drugs such as Clomid.

Many couples who are struggling with becoming pregnant opt for fertility drugs such as Clomid. This helps to stimulate ovulation in females, often making it easier for couples to conceive. In fact, professionals indicated that about 5 percent of all live births are possible thanks to in vitro fertilization. Although the side effects of the drug are minimal, a recent study has found that children of users may be shorter.

This information was uncovered when researchers from The Liggins Institute compared 84 children who were conceived with Clomid and other fertility drugs with 258 kids who were conceived naturally. Collectively, the children were all full-term babies and ranged from ages 3 to 10. Furthermore, findings were based on infants who were born at normal birth weights.

"Reassuringly, these children remained well within the for both their sex and age," Dr. Tim Savage said in a statement.

Of the children studied, those who were conceived by way of fertility drugs were an average of 2 centimeters shorter than the others. This was after the parents' height was taken into consideration - as this is the No. 1 factor in determining how tall a child will be.

More specifically, findings indicated that the difference was more prominent in males than females. When split up into groups based on gender, the boys were an average of 3 centimeters shorter if their mothers were taking fertility drugs. However, the collected information gave no indication of the reasoning behind this difference.

It's important for parents considering the use of Clomid to note that although the children were slightly shorter than their peers, they did not show any general health differences than kids who were naturally conceived. Researchers specifically looked at weight and body fat percentage, which remained healthy across the board.
