Men with dwarfism generally have normal sexual function if they are not combined with other pituitary hormone deficiencies. Dwarfism is caused by the lack of growth hormone secretion due to a variety of reasons, there are two aspects of congenital factors and acquired factors: 1. congenital factors: most of them are related to genetics, mainly short stature due to genetic inheritance, growth rate is lower than normal low value, sexual function is generally normal; 2. acquired factors: most of them are due to pituitary gland lesions resulting in growth hormone deficiency, the lack of growth hormone in early childhood will The lack of growth hormone in early childhood will show as slow growth, incomplete bone development, and height lower than the average height of normal peers. If there is no combination of other pituitary hormones such as gonadotropin deficiency, gonadal development is generally normal and there is normal reproductive capacity. If gonadotropin deficiency is combined with gonadotropin deficiency, gonadal development will be incomplete and sexual function will be affected.
