diapers cause infertility due to heat. Period, end of story. They trap way too much heat.
When my wife and I had our first child she got pregnant the very first week we tried. Over the next year, my incon started and by the time we started trying for our 2nd kid, I was in diapers every night and pullups during the day.
We tried for a full year and she just wouldn't get pregnant. I read this study and was convinced it was the diapers. I stopped wearing to bed and slept on a pile of towels every night. Sure enough, about 70 nights without diapers, just as the study results would predict, she got pregnant.
The timing is too spot on to be a coincidence and given that with our first child we got pregnant the first time we tried but struggled so much the second time with diapers being the ONLY variable, I'm certain this was the cause.

You may need to find a diaper alternative for a few months (cath or condom cath?)
