Actually it reads......
"It might be possible that the effect of zinc supplementation on free testosterone depends on exercise."
SO it might be, or it might not be.

This study is investigating hypogonadism in Korean men aged 40-60. Hypogonadism is a lack of hormones. Specifically in this case, testosterone. It's a little baffling as to how this study could be referenced to support Zinc intake affecting testosterone. All this study shows is that when testosterone levels are low, so are Zinc levels. It doesn't show that Zinc increases testosterone at all. It only describes the inverse relationship. When testosterone levels drop, so do Zinc levels. That's doesn't do any good in proving the opposite though.
This happens a lot. People will reference some silly study, and not bother to actually apply what the study says to the statement they're making.

Apparently you didn't want to quote that study.
Here you go.....

Subjects with normal testosterone group had a significantly higher Zn level compared to low testosterone group.
Normal testosterone is associated with a higher Zn level. Decreased serum testosterone is significantly associated with a high level of Cu and elevated Cu/Zn ratio in hair tissue.

Which is what I have said all along. If you are low in zinc you might also be low in natural test, or vice versa. So yeah, I'm right.
