Not really true.
Anyway, if you don't want children then you don't need to consider this. And when it comes to relationships, then maybe you should try and get into therapy to address your anxiety / rejection sensitivity and self-esteem issues. I would not buy into any pua stuff. You're better off just focusing on further developing empathy, social skills, and putting yourself in positions where you can actually meet women, on a regular bases. Eventually something will happen.
That's fair enough, there is the option of a sperm bank though which will mitigate the issue. For women they can freeze their eggs as well but pregnancy can be hard on their bodies and being older can be tougher to go through it, recovery ability drops with age too. In general men do have less worry on this than women do.
When you say PUA tip I hope you don't mean it about what I said! It's not PUA at all just a form of gradual exposure, skill and experience building which can be tried if he just can't approach.
The idea is to try yourself and develop the way to talk to ladies organically and not follow some pattern or rulebook someone else wrote for you (which is what PUA is) so you can naturally attract those who are genuinely a good match for you.
