Abstract excerpt
Genetic mechanisms are implicated as a cause of some male infertility, yet are poorly understood. Meiosis is unique to germ cells and essential for reproduction. The synaptonemal complex is a critical component for chromosome pairing, segregation and recombination. Hormad1 is essential for mammalian gametogenesis as knockout male mice are infertile. Hormad1-deficient testes exhibit meiotic arrest in the early...
