Hypergonadism is a condition where there is a hyperfunction of the gonads.[1] It can manifest as precocious puberty, and is caused by abnormally high levels of testosterone or estrogen, crucial hormones for sexual development. In some cases, it may be caused by a tumor, which can be malignant, but is more commonly benign.[2] Anabolic steroids may also be a major cause of high androgen and estrogen functional activity. Other possible causes include head injuries and brain inflammatory diseases.[3] Hypergonadism may contribute to symptoms such as precocious puberty and abnormal facial hair growth in females.[4]
