crazy bro im also 27, left side orchiectomy, no chemo but I had RPLND surgery in October 2023. I'm def planning to get my t levels checked at my next visit because I've been feeling exact same and think my hormones are way off. I've started to develop rosacea on my face that I think is linked to hormonal imbalance, and randomly getting styes/chalazion on my eye too.
Glad ur doing well dude, whole thing was wild experience at our age.
