“…VCL, VSL and ALH were all documented to correlate with the fertilizing ability of spermatozoa [6] as well as reproductive outcomes [5,14,151. Chan et al [5] reported that in women undergoing in vitro fertilization, VCL was much higher for fertile couples when compared with fertile couples.…”

“…A film clip was recorded, the clips were edited to constant length (1 s, 25 frames) and analyzed using CellTrak 1.5 software (Motion Analysis Corporation, Santa Rosa, CA, USA). Sperm swimming speed was determined as average curvilinear velocity of motile sperm cells in each film clip [44]. Sperm velocity threshold of less than 10 µm s −1 was used to calculate percentage of motile sperm.…”

Larval stages are among those most vulnerable to ocean acidification (OA). Projected atmospheric CO 2 levels for the end of this century may lead to negative impacts on communities dominated by calcifying taxa with planktonic life stages. We exposed Mediterranean mussel (Mytilus galloprovincialis) sperm and early life stages to pH T levels of 8.0 (current pH) and 7.6 (2100 level) by manipulating pCO 2 level (380 and 1000 ppm). Sperm activity was examined at ambient temperatures (16-17• C) using individual males as replicates. We also assessed the effects of temperature (ambient and ≈20• C) and pH on larval size, survival, respiration and calcification of late trochophore/early D-veliger stages using a cross-factorial design. Increased pCO 2 had a negative effect on the percentage of motile sperm (mean response ratioR = 71%) and sperm swimming speed (R = 74%),Water 2013, 5 1891 possibly indicating reduced fertilization capacity of sperm in low concentrations. Increased temperature had a more prominent effect on larval stages than pCO 2 , reducing performance (R Size = 90% andR Survival = 70%) and increasing energy demand (R Respiration = 429%). We observed no significant interactions between pCO 2 and temperature. Our results suggest that increasing temperature might have a larger impact on very early larval stages of M. galloprovincialis than OA at levels predicted for the end of the century.

“…Hinting et al [24] reported the best discrimination between fertile and subfertile men was the proportion and concentration of sperm with rapid linear progressive velocity. In the present study, the values of VAP and VCL representing the sperm swimming speed were significantly decreased by the administrations of dinoseb.…”

Abstract. The computer-assisted sperm motion analysis (CASA) system has been used as one of the useful means for reproductive toxicity studies in male animals. Since various parameters of sperm motility are measured by the CASA system, we investigated the effects of a herbicide dinoseb, a testicular toxicant, and which parameter was the most appropriate for detecting changes. Crj:CD(SD)IGS mature male rats were administered dinoseb at a dose of 0 (corn oil), 5 or 7.5 mg/kg for 3 consecutive days, and were necropsied for cauda epididymal sperm analysis after a 12-day (Day15) or 19-day (Day 22) withdrawal period (Experiment I). No sperm motility parameters of dinoseb-treated rats were changed on Day 15, but on Day 22, the percentage of motile sperm (MOT) was significantly decreased in rats treated with dinoseb at 7.5 mg/kg. Other parameters, such as path velocity (VAP), curvilinear velocity (VCL), and amplitude of lateral head displacement (ALH) were significantly decreased as well. In Experiment II, no parameters of sperm motility showed any change in rats treated with dinoseb at 7.5 mg/kg three times per week when evaluated on Day 21. It was concluded that MOT, VAP, VCL, and ALH were more sensitive to dinoseb effects on sperm in the CASA system.
