SEXUAL DESIRE, TESTICULAR MEASUREMENTS AND SEMEN QUALITY OF BUFFALO BULLS TREATED WITH COMBINATIONS OF TRACE ELEMENTS AND VITAMIN E. [PDF]
Journal of Animal and Poultry Production, 2010 A total of twenty healthy Egyptian buffalo bulls with an average of 500 kg live weight and 2.5 - 4.0 years old was used to study the effect of selenium and vitamin E (Se+Vit. E), Se and zinc (Se+Z), Vit. E+Z and Se, Vit. E+Z) on sexual desire, testicular

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development
PROTEOMICS, EarlyView.ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

The use of deidentified organ donor testes for research
Andrology, EarlyView.Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Andrology, EarlyView.ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.
