Post-Meiotic Intra-Testicular Sperm Senescence in a Wild Vertebrate [PDF]
, 2012 There is growing interest in sperm senescence, both in its underlying mechanisms and evolutionary consequences, because it can impact the evolution of numerous life history traits. Previous studies have documented various types of sperm senescence, but

Semen collection and evaluation of captive coatis (Nasua nasua)
Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2012 Semen samples (n=105) were collected through eletroejaculation from six adult male coatis (Nasua nasua) between January 2007 and December 2008 at Universidade Federal de Mato Grosso Zoo, Cuiabá, Brazil. Mean values were: volume (mL); concentration (sperm/
