Mild androgen insensitivity syndrome presenting as male infertility with azoospermia

Androgen insensitivity syndrome results from a mutation in androgen receptor gene. It has wide spectrum of phenotypic presentations. Mild androgen insensitivity syndrome (MAIS) is the milder form, present as undervirilized male syndrome. In some instances, the only observed abnormality appears to be male infertility; therefore, MAIS could explain some cases of idiopathic male infertility. Here we describe a case of MAIS in a 38 years old male who presented with azoospermia and infertility.
