Question

Quizplus · Accepted Answer

The boy's rapid growth and tall height, as well as normal body proportions and only slightly delayed sexual development suggest an excess of growth hormone, which stimulates growth and can cause gigantism if hypersecreted during childhood. Vitamin D synthesis, testosterone secretion, and adrenal tumors would not cause this combination of symptoms, and hyposecretion of growth hormone would lead to stunted growth.
