4% of total Vorinostat sperm (Fig.?4G), suggesting that the majority of sperm in the JE was categorized in group I during the observed time period. The UM wave velocities in the group I sperm were significantly higher at the posterior midpiece (P?SB203580 manufacturer & Dent 1986; Ukita et?al. 1999). To evaluate the specific feature of the sperm motility state in the jelly substances included in JE, we characterized the motility state of sperm in a hyposmotic solution. Sperm were suspended in 10?mmol/L Hepes-NaOH (pH6.9) and, after 1?min, motility was recorded in 83 sperm for 9?min. Only 35?��?7.7% of the total sperm maintained a continuous UM wave throughout the midpiece and principal piece during the observed time period (Fig.?2). Although these sperm often exhibited no forward movement, they showed a variety of UM wave velocities both in the anterior and posterior midpiece (Fig.?3C,D). The group I sperm showed wave velocities of 274?��?16.0?��m/s at the anterior midpiece and 329?��?21.2?��m/s at the posterior (Fig.?4B). The group II sperm showed wave velocities of 158?��?49.5?��m/s at the anterior midpiece and 141?��?9.03?��m/s at the posterior. The group III sperm showed wave velocities of 169?��?45.9?��m/s at the anterior midpiece and 71.2?��?9.37?��m/s at the posterior. The wave velocities of the UM at the posterior midpiece of the group I sperm were significantly higher (P?GPX5 lower (P?
