Rajshree Patil with family and Dr Puranik 

The medical process of semen cryopreservation has helped a city-based family get back their son. A teacher by profession, Rajashree Patil, 50, used the preserved semen of her unmarried son, a 27-year-old who died of brain tumour two years ago, to have grandchildren. After an aunt of the deceased volunteered to become the surrogate mother, doctors fused the son's semen with the donor's eggs and transferred them to the latter's womb. Prathamesh Patil's aunt delivered healthy twins – a boy and a girl – this week at Sahyadri Speciality Hospital on Ahmednagar road.
