“High prolactin may decrease pulsatile GnRH secretion by the hypothalamus, leading to a decrease in pituitary gonadotropin secretion and subsequent testicular dysfunction. This hypogonadotropic hypogonadism will result in low testosterone levels. Testosterone deficiency in men is associated with a number of complaints related to sexual dysfunction.”
From what I understand, levels associated with Prolactinomas are generally found to be MUCH higher than the reference range (ie, often in the 30-100s, in the 100s, or 1000s). Regardless, a guy approaching the upper end of the reference range (ie, 13 in a range of 1-15 for Prolactin) or above it may want to discuss an MRI scan or possible dopamine agonist treatment options to lower prolactin. I recall reading somewhere that Dr. Shippen likes to keep prolactin between 3-5, but I could be wrong.
Besides being caused by a prolactinoma, Prolactin can also be increased due to elevated estrogens (common in ex-Fin users) and due to Hypothyroidism (also a problem some guys have post-Fin) –

“Excess production of prolactin may occur in people with hypothyroidism — insufficient hormone production by your thyroid gland. This usually occurs only in people with longstanding untreated hypothyroidism.”
