Dear Felix:

Realistically, for a guy 43 years old isn’t too old for anything, including starting a family. There are many men who had kids in their 50s and they live long enough for those kids to grow up and start their own families. Although it is harder to start a family later in life, due to physical limitations, as you say, it’s not impossible, and for many it’s worked just fine.

And another thing, it’s not just physical health that matters for a happy family, it’s also mental and emotional health. Now you’re much more mature and self-aware than 15 years ago, and you have a much better chance to sustain a happy marriage and have happy, healthy kids. Many immature young men end up having children and messing them up. You’re lot less likely to do that. So there’s even a benefit of starting a family when you’re more mature.

You also mention culture limitations. What exactly did you have in mind?
