“As a pioneer in medicine and specifically reproductive health, Dr. Jain has changed the landscape of reproductive medicine and advancements in fertility, both in chemistry as well as approach.
I was honored to have worked with him for over a decade while he was innovating and changing the course of fertility medicine, and happy to see novel ideas being born, along with thousands of babies. You can take a look at his resume for everything that he invented, but once you meet him and his team, you know instantly that this is not only a change agent but an expert in medicine and fertility, from germ cell to bouncing baby.”
