Y chromosome microdeletions frequency in idiopathic azoospermia oligoasthenozoospermia and oligospermia

摘要

Background:Genetic factors are candidates for about 30% of male infertility with sperm production-related abnormalities. Y chromosome microdeletions are responsible for around 10% of male infertility. These microdeletions generally occur in azoospermia factor on the Yq. That is often associated with the quantitative reduction of sperm.
