Can a tumor cause low testosterone?

Why would a tumor on the pituitary gland affect levels of testosterone?

Overproduction of prolactin from a pituitary tumor (prolactinoma) can cause a decrease in normal levels of sex hormones — estrogen in women and testosterone in men. Excessive prolactin in the blood affects men and women differently. In women, prolactinoma might cause: Irregular menstrual periods.

Can pituitary tumour be seen on CT scan?

Does pituitary stalk compression cause hyperprolactinemia?

Hyperprolactinaemia may be caused by either disinhibition (e.g., compression of the pituitary stalk or reduced dopamine levels) or excess production from a prolactinoma (a type of pituitary adenoma ).
