You talk about "not having children" as a decision that you alone made, not a joint decision with your wife. (I'm assuming from the mention of a biological window that your spouse is a woman). I don't know if this is just the way you worded it but the first thing you should do if you haven't already is discuss this with her. Does she want children now? Others have pointed out that it's not necessarily too late biologically for a woman at 39 and I'd add my own experience to that - my wife had our children at 38 and 41, and we had no issues with either conception or pregnancy. So don't assume it's impossible. If you are in a place where she doesn't want children now and you do though then that puts your relationship in a very difficult place and perhaps you should try couples counseling if you haven't already. If she's open to looking after children but doesn't want to (or can't) go through a pregnancy then there are other options like surrogacy or adoption which might be open to you. A good couples counselor should be able to help you discuss this in a way which is safe both of you.
