It's definitely a trend, and the handwriting is on the wall for anyone using chimpanzees in research.

Best Answer: CONCLUSION: Weight gain and elevated body weight are frequently associated with prolactinomas regardless of a mass effect on the hypothalamus or pituitary function. In this series, weight loss was recorded in 70% of prolactinomas patients and in 90% of male patients who normalized their prolactin levels. We propose the inclusion of hyperprolactinaemia in the differential diagnosis of endocrine obesity and weight gain.
In women, symptoms caused by the high prolactin levels can include: 1  Infertility. 2  Changes in menstruation. 3  The production of breast milk in women who are not pregnant or nursing.  Loss of libido (interest in 1  sex). Vaginal dryness.  Painful intercourse (because of vaginal dryness).
