@ankara-- As far as I know, yes it can. Testicular atrophy is due to low levels of testosterone, correct? And since low LH will result in low testosterone levels, it indirectly can cause testicular atrophy.
Not just this, but it can also cause depression, breast growth and many other symptoms.
I have a friend who experienced many of these due to steroid use. Low LH and low testosterone can be side effects of steroids.
