Idiopathic Oligozoospermia

Meaning

A clinical diagnosis in male reproductive health characterized by a low concentration of spermatozoa in the semen, termed oligozoospermia, for which no definitive underlying medical cause can be identified following a thorough diagnostic evaluation. The ‘idiopathic’ classification highlights a likely multifactorial etiology involving subtle genetic, environmental, or endocrine disturbances that evade standard clinical detection. It represents a significant clinical challenge in the management of male factor infertility.
