Thank you for your question.

Obstetrics and Gynecology are two surgical–medical specialties dealing with the female reproductive organs in their pregnant and non-pregnant states, respectively, and as such are often combined to form a single medical specialty and postgraduate training program.

SRI RAMACHANDRA MEDICAL COLLEGE & RESEARCH INSTITUTE ( SRMCRI),CHENNAI for example has fees of 13 lakh per year. 

Kasturba medical college has an annual fees of around 15 lakh per year.

MAHATMA GANDHI INSTITUTE OF MEDICAL SCIENCES ( MGIMS WARDHA),WARDHA Has fees of around 6.5 lakh

On an average, you can expect fees around 5 to 10 lakh in a deemed university. 

Good luck .
