Since the Sertoli<unk> s are not affected by<unk> , anti-Müllerian hormone is secreted normally and so there are no Müllerian structures. Wolffian structures, such as the prostate, vasa deferentia, and epidydimides are present. In type I, abdominal testes are revealed on ultrasound; in type II testes may be descended or undescended. People with<unk>  type I display no response to the hCG stimulation test; there is no increase in serum levels of testosterone and dihydrotestosterone.<unk>  type II can display either a pronounced rise of testosterone levels or no rise. In any case, the diagnosis is confirmed on biopsy of the testes, revealing either absent or hypoplastic<unk> <unk> s. The inside of the testis will be grayish and mucous, displaying arrested spermatogenesis and the presence of Sertoli<unk> s. The diagnosis can also be confirmed by looking for mutations in the gene for the LH receptor. A diagnosis of<unk>  is usually made in the neonatal period, following the discovery of ambiguous genitalia, or at puberty, when secondary sex characteristics fail to develop. Puberty is the most common time for<unk>  to be diagnosed.
