Comparación de la sobrevida y de los patrones de movilidad de espermatozoides incubados en medios HAM′S-F10 y G-IVF

objective: to compare survival and motility of sperm incubated in ham？s-f10 and g-ivf media. methods: subsamples of motile sperm recovered by density gradients of 31 normospermic men were incubated in each medium for 18-20 hours in 5 % co2 atmosphere. subsequently, sperm survival and motility were assessed. setting: unidad de fertilidad unifertes, clínica el ávila. caracas, venezuela results: average sperm survival and progressive motility were significantly higher in g-ivf (p<0.01). consequently, average percentage of immotile sperm was significantly lower (p<0.01). conclusion: sperm survival and progressive sperm motility were significantly higher in g-ivf medium than in ham？s-f10.
