P-209: Decreased Expression of Histone Acetyltransferase CDY1 Gene in Testis Tissue May Lead to Decreased Expression of Transition Protein (TNP) and Protamine (PRM) Genes,Causing Male Infertility

Background: Infertility is a complex medical problem. About 15% of couples are infertile, and male infertility being involved in roughly 50% of the cases. Among these, many cases are associated with a severe impairment of spermatogenesis.
