متن کاملCryopreservation of Boar Semen Studies on sperm viability in vitro and fertility
Eriksson, B. 2000. Cryopresewation of boar semen. Studies on sperm viability in vitro and fertility. Doctoral thesis. ISSN 1401-6257. ISBN 91-576-5903-6 The world’s pig population is consistently being upgraded through the international trade of superior genetics. The two major systems that are used for this purpose are the transport of live animals and the export of frozen boar semen. The main...
متن کاملOxidoreductive capability of boar sperm mitochondria in fresh semen and during their preservation in BTS extender.
The purpose of our study was to determine the effect of dilution and liquid-preservation of boar sperm on oxidoreductive capability of their mitochondria. The semen was diluted with BTS extender produced from water purified by destillation or by reverse osmosis. The spermatozoa were stored over a four-day period at 16-18 degrees C. The function of sperm mitochondria was assessed using the scree...
متن کاملResponse to capacitating stimuli indicates extender-related differences in boar sperm function.
Spermatozoa, especially those of the porcine species, are highly susceptible to in vitro chilling and ageing. Extenders are continuously developed to protect boar spermatozoa from chilling injury. New semen extenders and other modified preservation strategies require sensitive testing for essential sperm functions. The key process on the pathway of fertilization is capacitation. The aim of the ...
متن کاملAcrosin release and acrosin activity during incubation in capacitating media using fresh and frozen-thawed dog sperm.
We evaluated the effect of time and temperature on acrosin release from the acrosomal cap and the activity of this enzyme during in vitro capacitation in fresh and frozen/thawed dog sperm. Sperm-rich fractions of six ejaculates from three dogs were processed as fresh and frozen samples. Each sperm sample was incubated in canine capacitation medium (CCM) for 0, 1, 2 and 3 h at 20°C and at 37°C. ...
