Hello everyone, i am a 21 year old male 175 cm 74 kilograms with fat mostly concentrated around the belly. I have had low testosterone and low SHBG since several years and i have been trying to figure our what is the cause. Recently i had my Hba1c tested and it turned out 5.8, which as i read is pre diabetic, but strangely several months ago i had had a fasting glucose test which turned out to be normal. So i am wondering which one is more precise and if i am prediabetic is this causing my testosterone problems ? Thank you.
