<human>: Can you provide a brief overview of the text?

So I got the news a couple of days ago, that due to low sperm count my chances of fathering children are astronomical. I was never sure I really wanted kids to be honest so I'm indifferent about the whole thing at the moment. 

One thing playing on my mind is how long should I wait to tell my partner, we've only been together for 3 months so having kids isn't on the agenda, however I'm not getting any younger and any relationships in future need to be looked at as "grown-up" relationships where marriage and kids could be a possibility.

It's awkward because it seems an odd thing to say to someone after such a short term relationship but on the other hand it wouldn't be fair to wait too long, fall in love and then tell them afterwards, it could cause them to make a decision based on that over what they would have really wanted.

Whats my best course of action here? Both for now and any potential future relationships?
