Hi Guys/Ladies

I have been reading that after using BO males get shrinkage in testicles and penis. I want to know that the reason behind it. I read here many claims it is due to new circuits in brain but I don't see any concrete/scientific evidenc to support it. Is it possible that testicles stop working after getting damaged by BO?Would somebody will help me to understand the shrinkage of tisticles here.

thanks

Estrogen shrinks testicles. Estrogen => lower LH from hypothalamus. LH is needed to activate testicles.

Look up "Hypothalamic–pituitary–gonadal axis". This one has a nice diagram:
