Ratnam several sperm motility parameters in semen prepared by the swim-up technique were compared with ivf rates in 84 patients. Computerized motility analysis provides a number of objective measures of sperm motion characteristics taken from tracks of large numbers of sperm, including percentage of motile sperm, percentage of progressively motile sperm (i.). Purpose the direct effects of lepidium meyenii (maca) on sperm remain unclear. Herein, we examined the direct effect of maca on in vitro fertilization. Methods we examined the fertilization rate in a mouse model and the rate of acrosome reaction in sperm from transgenic mice expressing enhanced green fluorescent protein (egfp) in a maca extract-containing human tubal fluid (htf) medium. Prognostic significance of computerized motility analysis for in vivo fertility. Garrett, c, liu dy, clarke gn, rushford dd and baker hw (2003). Automated semen analysis zona pellucida preferred sperm morphometry and straight-line velocity are related to pregnancy rate in subfertile couples.

Samples were analyzed at different time points (0, 60, 150, 240, and 300 minutes) based on the half-life of ra in plasma. All concentrations of ra used in this study significantly (p0. 05) increased sperm motility with a maximum after 240 minutes of incubation (fig.).
