Do all patients with prolactinomas need treatment?
Most do. If you have infertility problems, excessive milk production or a large tumor causing pressure symptoms, then there is a clear case for treatment. If not, then the need may not seem so clear. However, prolonged sex-hormone deficiency (estrogen in women and testosterone in men) causes thinning of the bones, or osteoporosis, or in some cases, other problems. Therefore, most doctors believe that women without regular periods should receive treatment. The same applies to men with low testosterone levels.
