I am not a man, but this reminds me of a time years ago when I started to have allergic reactions to things several times a day. My allergist put me on a strict elimination diet of triggers. I could only use unscented products for bathing and laundry, organic food only, and I even had to get rid of my teflon pans and use only stainless steel or cast iron. It sucked but it did seem to help, maybe you could try something like that too.
I really didn't consider brand. I thought it would be easy enough to determine a copper pan versus a teflon or iron pan that branding wouldn't offer any advantages.
I had some relatively severe allergic reactions to (apparently) enzymes in laundry detergent, once we stopped that it went away, and doesn't seem to come back even with minor enzyme encounters.
Well if you spend too much time sitting and don't reduce your calorie intake to match, you get fat. Being fat generally does bad things to your health, and one known example of that is that being fat reduces your fertility.
Being fat correlates with reduced fertility. It may ultimately be caused by whatever thing that results in reduced fertility, but there is no evidence of being fat causing reduced fertility.
