Glucose ingestion was associated with a 25% decrease in mean T levels (delta = -4·2 ± 0·3 nm, P < 0·0001). T levels remained suppressed at 120 min compared with baseline (13·7 ± 0·6 vs 16·5 ± 0·7 nm, P < 0·0001) and did not differ across GT or BMI. Of the 66 men with normal T levels at baseline, 10 (15%) had levels that decreased to the hypogonadal range (<9·7 nm) at one or more time points. SHBG, LH and cortisol levels were unchanged.

*hypogonadal means castrate levels. It was pure Glucose as we find in Cola, Sweets, Fastfood and stuff like this. Normal Sugar is a di-sacharid glucose+fructose and honey is mostly fructose yes. Fructose is not fast acting. Paper. They used 75g (which is high but achievable for fast and junkfood eaters) but when you do high intensive training your metabolism is altered anyways.
