HSFY genes and the P4 palindrome in the AZFb interval of the human Y chromosome are not required for spermatocyte maturation

Abstract

Although the HSFY deletion is restricted to our infertile group, it has been transmitted naturally over many generations, indicating that HSFY genes make only a slight contribution to male fertility. Importantly, our study formally excludes HSFY genes as the AZFb factor required for progression through meiosis.
