IVF expert explains science behind multiple babies in short span

Dr Pallavi Prasad, a fertility consultant at Nova IVF Fertility, Basaveshwaranagar, Bengaluru, told indianexpress.com that couples “having good quality surplus embryos” can always choose to go for “vitrification” and freeze them for future use.

The expert adds that the number of embryos created during an IVF cycle depends on the number and quality of egg and sperm of the couple.

According to Dr Prasad, embryo freezing is suitable for:

Any couple going for IVF treatment, so they can have frozen embryos for multiple attempts or to have babies in future; these same embryos can be used.

Couples who want to get pregnant later in life (due to issues like financial stability, emotional readiness).

Couples undergoing treatment that may damage their sperm and eggs. For example, cancer treatments like chemotherapy.
