One of the main characteristics of this disorder is<unk>  insufficiency, which is a reduction in<unk>  gland function resulting from incomplete development of the gland's outer layer (the<unk>  cortex).<unk>  insufficiency typically begins in infancy or in childhood and can cause vomiting, difficulty with feeding, dehydration, extremely low blood sugar (hypoglycemia), low sodium levels, and shock. However, adult-onset cases have also been described. See also Addison's disease. Affected males may also lack male sex hormones, which leads to underdeveloped reproductive tissues, undescended testicles (cryptorchidism), delayed puberty, and an inability to father children (infertility). These characteristics are known as hypogonadotropic hypogonadism. Females are rarely affected by this disorder, but a few cases have been reported of<unk>  insufficiency or a lack of female sex hormones, resulting in underdeveloped reproductive tissues, delayed puberty, and an absence of menstruation.
