Última Seasonal variations in the heterologous binding of viscacha spermatozoa: A scanning electron microscope study Biocell Aguilera Merlo,Claudia; Muñoz,Estela; Dominguez,Susana; Fóscolo,Mabel; Scardapane,Luis; de Rosas,Juan Carlos. Seasonal changes in the reproductive activity of the adult male viscacha (Lagostomus maximus maximus) were investigated during the annual reproductive cycle. Assays of heterologous in vitro binding between compatible gametes were used to evaluate the ability of viscacha spermatozoa to achieve primary binding during its annual reproductive cycle. Sperm were collected by mincing cauda epididymis in HECM-3 medium and the sperm concentration and motility were evaluated. Cumulus-free and zona-free oocytes obtained from superovulated hamsters were inseminated in vitro with capacitated sperm suspensions, incubated at 37ºC, 5% CO2 for 3 h, and then processed for studies by scanning electronic microscopy. Statistical analysis was used to compare the quantitative...
