About IRM

Institute of Reproductive Medicine


A brain child of Prof. B.N. Chakravarty was built in 1983 at Salt Lake (Old Building) to complete the unfinished job of Late Dr. Subhas Mukherjee who had pioneered the delivery of “First Test tube Baby” in India and 2nd in the world after his unfortunate demise.

Prof. B.N. Chakravarty trained a team of dedicated young doctors who with their sincerity, devotion, and knowledge helped the infertile couples at IRM to fulfill their dreams under the guidance of Sir who delivered 3rd Test tube Baby in November 1986.This was the most important milestone in Prof. B N Chakravarty’s clinical career.

Lack of adequate space at the old building due to gradual increase in number of infertile couplies desperate to achieve pregnancy, Sir built a second building of IRM at Salt Lake popularly known as new IRM building. About 3000 to 3500 new patients are turned up every year and 20 to 30 Doctors are enrolled for training program each year from all over the country. Till date about 6000 babies were born from IVF/ICSI.
