If you had the choice to go back into the womb of your mom, for whatever reason, would you?
Thankfully it can't be done, but there may be times when some moms would wish that their baby could go back into the womb. To correct an issue that could've prevented a miscarriage.

To be born again would be to save a life. And just like Jesus mentions to Nicodemus that you can't enter the Kingdom of God unless you are Born Again.  Religion can't take you there, You Must Be Born Again?
