Improved assessment of frozen/thawed mouse spermatozoa using fluorescence microscopy
Ann-Kathrin Diercks, Heinrich F. B?rgers, Anna Schwab, Johannes Schenkel* 대한수의학회 Journal of Veterinary Science 8 Pages

the same mouse line might be heterogeneous and the cryopreservation procedure might also be error-prone. However, only limited amounts of material are available for analysis. To improve the monitoring of frozen/thawed spermatozoa, commonly used in vitro fertilization (IVF) followed by embryo transfer were replaced with animal-free techniques. Major factors for assessing spermatozoa quality (i.e., density, viability, motility, and morphology) were evaluated by fluorescence microscopy. For this, a... -
A comparative study of Sephadex, glass wool and Percoll separation techniques on sperm quality and IVF results for cryopreserved bovine semen
Hae-Lee Lee, Sue-Hee Kim, Dong-Beom Ji, Yong-Jun Kim* 대한수의학회 Journal of Veterinary Science 7 Pages

sperm quality and in-vitro fertilization (IVF) results for cryopreserved bovine semen. Sephadex, glass wool and Percoll gradient separation techniques were used for sperm separation and sperm motility, morphology and membrane integrity were evaluated before and after separation. Also, cleavage and blastocyst developmental rate were investigated after IVF with sperm recovered by each separation technique. The motility of samples obtained by the three separation techniques were greater compared to... -

controls) on quality parameters (membrane integrity, progressive motility, path average velocity) in either species. Similarly, there were no detrimental effects after cryopreservation in either species. The fertilizing potential of encapsulated and cryopreserved semen was evaluated after AI in 25 buffalo and 113 bovine females. Pregnancy rates were not affected in either species. The results of this study show proof of concept for the use of frozen semen controlled-release devices in buffalo. -
Development of in vitro produced porcine embryos according to serum types as macromolecule

This study was conducted to establish an in vitro maturation (IVM) system by selection of efficient porcine serum during porcine in vitro production. To investigate the efficient porcine serum (PS), different types of PS [newborn pig serum, prepubertal gilt serum (PGS), estrus sow serum, and pregnancy sow serum] were used to supplement IVM media with or without gonadotrophin (GTH) and development rates of parthenogenetic activation (PA) and in vitro fertilization (IVF) embryos were then... -
돼지 정액의 간편 동결 방법 확립과 동결 정액의 융해 후 생존성 평가

본 연구는 돼지정액의 보다 간편하고 손쉽게 동결시킬 수 있은 방법을 확립하기 위하여 수행하였다. 돼지정액은 3시간에 걸쳐 $5^{circ}C$까지 냉각 후 Straw에 봉입하고 다양한 방법 및 step에 의해 스티로폼 용기 내에 들어있는 $LN_2$ 중에서 동결하였다. 정자의 생존성은 $LN_2$ 표면으로부터 10 cm 위에서 10분간 정치 후 침적할 경우 가장 높게 나타났다(54.0%). Straw를 $-102^{circ}C$에서 10분간 정치시킨 처리구가 여타구보다 높은 생존성이 얻어졌다(74.0%, P<0.05). 응해 방법에 따른 동결정액의 생존성 실험에서는...
