by what mechanism prolactine drives your testosterone low?

I need to know the mechanism. I know it is a big cause of infertility in men and women but how?

Does it saturate ARs and T converts to E and then through negative loop back E drives our LH and FSH to go down?
OR
high prolactine cuases damage to brain and pitutary?

Guys come on. I need to know how prolactine decreases your Testosterone? what is the mechanism.

Use Google.

When I was Prolactin (25) over the limit (2~17) my Testosterone was in 210 (190~781), take blood test if high take Dostinex
