A quantitative description of flagellar movement in golden hamster spermatozoa.
Flagellar movement of golden hamster spermatozoa obtained from the testis and the caput and cauda epididymides was observed by a light microscope while holding them at their heads with a micropipette. Flagellar movement of capacitated spermatozoa and of reactivated spermatozoa demembranated with Triton X-100 was also observed. Testicular and caput epididymal spermatozoa showed weak movement in ...
متن کاملQuantitative analysis of flagellar movement in hyperactivated and acrosome-reacted golden hamster spermatozoa.
Caudal epididymal spermatozoa of golden hamsters were incubated in capacitation medium. Their movement patterns changed as they became hyperactivated and underwent the acrosome reaction. To understand the basic mechanism by which changes in movement pattern are brought about, digital image analysis was carried out on the flagellar movements recorded with a video system.

متن کاملOocyte penetration by fresh or stored diluted boar spermatozoa before and after in vitro capacitation treatments.
This study examined whether washing and preincubation of boar spermatozoa was necessary to achieve high in vitro penetration rates of pig oocytes. In experiment 1, diluted, sperm-rich fractions, stored for 24 h at 16 degrees C (stored diluted sperm) were used. After centrifugation once at 50 g for 3 min, the supernatant was concentrated at 1200 g for 3 min. The pellets were washed (1200 g for 3...
