Lol both.
I actually want us both to get tested to see if we can. Back in 2016 she got pregnant but it ended up being an ectopic pregnancy. So we are wondering since that happened, if she still can. Since then, nothing.
It's actually quite common for couples to have issues. Lots of our friends have had issues. We were blessed in that regard. She got pregnant the first time within about a month of trying. I credit that with my exceptional virility.
