Seems that 'fertility doctor' is a simple hack for personal breeding program. There are more of these cases too.
One of these guys had 100+, and until he was caught, had zero child support costs. He's like a cockoo bird.
(Not saying it's moral, hacking may or may not be moral.)
I'm not sure most people get a medical degree to "obtain one suitable mate and have a few offspring". I think most people do that to be a medical practitioner.
You could say people want to be medical practitioners because they want to find love and start a family but you could also say they want it because they want to be comfortably wealthy and financially secure.
