This is just another way to get you to prioritize work (them) over family (you).

Putting things off for later tends to mean putting them off forever. You aren't getting any healthier. Running after little ones isn't easier when you are old. Maybe you freeze a few... but is that enough? Maybe you will really like having kids.

Also, freezers fail. I think it was just a few months back that a large facility had a huge failure that wiped things out for a huge number of couples. Oopsie, so sorry! Getting a refund is unsatisfying when you were expecting a child born of your own flesh and blood.
