Effects of coffee consumption on testosterone production Does consumption of coffee affects hormone, precisely testosterone production in a noticeable way? And if so does it increases it or decreases it?

Also I'm not looking for any type of super scientific answer I just wanted to know to satisfy my own curiosity.
In short, caffeine may increase "Sex Hormone Binding Globulin" which results decreased levels of testosterone in both men and women.

However, I don't know how effective it is. Or if this decrease is serious and supported by many studies. I have encountered this study presents that caffeine's inverse effect on women testosterone level, which is somewhat related to osteoporosis as far as I can interpret.
