Umesh N. Jindal, a gynaecologist, said the success rate of in-vitro fertilisation, a technique more than 35 years old, was 50 percent per attempt. The reasons for increased success rate are advances in embryology, freezing of embryos, and improved quality of equipment and medicine. Another gynaecologist, Abha Majumdar, spoke on the status of new medicine for the treatment of diseases like fibroids, endometriosis and low sperm count.
