It is said that Gandhari gave birth to a piece of flesh, after being pregnant for 2 years. If you take an actual gestation period, it is actually 10 months and 2 years is something abnormal. And in a lifetime, even if she had twins/quadruplets or multiplets, its not possible to have 101 children.
Sage Vyasa actually advised her to save the foetuses in small earthen pods and he filled it with some ghee and herbs and used his powers. After another 2 years of waiting, all 101 children were born (100 boys and 1 girl) in the Kauravas clan.
So, the modern day’s test-tube baby birth actually dates back to Mahabaratha era. It seems as simple as this but it involves such a complex procedure and the success rate is also less.
Now, is the In vitro fertilization (IVF), is a discovery or an invention?
