• Chronological Changes in Fertilized Eggs of the Mongolian Gerbil (Meriones unguiculatus).

抄録

There have been very few reports about fertilized eggs of the Mongolian gerbil. This study was therefore designed to determine the chronological changes in fertilized eggs of the Mongolian gerbil. Superovulated females were monogamously paired with males and pregnant females were killed at 16, 19 and 22 hours after hCG injection. After slaughter, the presence of female and male pronuclei and sperm tail was examined. Rates of female and male pronuclei increased with the collection time for fertilized eggs (24.5, 58.9 and 67.9% at 16, 19 and 22 hr, respectively). Rates for a fertilizing sperm tail out of the total number of fertilization eggs decreased with the collection time for fertilized eggs (85.0, 58.0 and 28.0% at 16, 19 and 22 hr, respectively).
