Sexual infantilism or genital infantilism is the syndrome of delayed or arrested development of sexual organs i.e., delayed puberty or absent puberty observed for a number of congenital and endocrine disorders.
Examples of disroders that exhibit sexual infantilism are the Turner syndrome and various forms of congenital adrenal hyperplasia.
Abhormal pubertal progressing may be observed for testicular failure, associated with low testosterone levels and high gonadotropin levels, with most common cause being the Klinefelter syndrome. Other possible causes of testicular failure are mumps orchitis, Coxsackievirus B, irradiation, chemotherapy, and trauma. Testicular failure is treated with testosterone replacement.
Observed for gonadotropin deficiency, as in boys and with primary ovarian failure.
