    • Efeito da varicocele e de sua correção cirúrgica nos mecanismos moleculares proteômicos e inflamatórios do sêmen 

      Camargo, Mariana [UNIFESP] (Universidade Federal de São Paulo (UNIFESP), 2016-12-13)
      Introduction: Varicocele is the main treatable cause of male infertility. On the other hand, not all men with varicocele will be infertile. There are several proposed mechanisms to explain varicocele-derived infertility, ...
