The Robertsonian translocation of '21/22' in Nonobstructive Azoospermia: A Rare Case Report from India.

Robertsonian translocation is a subtype of balanced translocation involving two acrocentric chromosomes. Individuals who are carrier of this abnormality are at increased risk of infertility or bad obstetric history. This case is reported with the aim to describe a male who presented with nonobstructive azoospermia at a tertiary care center. The individual was phenotypically normal but carrier of a Robertsonian translocation of two acrocentric chromosomes. With this literature, we emphasize that conventional cytogenetic is an essential diagnostic tool for screening genetic factors in infertility.
