What is the newly developed drug for?

A fertility drug designed to produce a pregnancy leading to an early single birth instead of dangerous multiple births has been developed by a doctor who says it could be marketable in four or five years. Dr. Roseberg, research director at City Hospital’s Medical Research Institute, will seek permission from the U. S Food and Drag Administration next week to start testing the drag on women in the United Sates. She said hormonal preparations available to date for treatment of female infertility due to hormonal im0alance carry the risk of inducing multiple pregnancies which may result in physical danger to the mother and newborns.
