Comparison of Fertility on Intrauterine Insemination between Cryopreserved Ejaculated and Cauda Epididymal Sperm in Dogs.
Summary of "Comparison of Fertility on Intrauterine Insemination between Cryopreserved Ejaculated and Cauda Epididymal Sperm in Dogs."
The fertility was compared between ejaculated and cauda epididymal sperm sensitized with prostatic fluid in dog after freeze-thawing using the fertility of ova from the contralateral ovary after injection (2 × 10(8) sperm) into dog uterus on the unilateral ovariectomized side, on the basis of the presence or absence of conception. No significant difference was observed in sperm quality after freeze-thawing between the two groups and conception rates were equivalent and low. Therefore, to achieve a high fertility by intrauterine insemination of canine frozen-thawed ejaculated and cauda epididymal sperm, intrauterine insemination on both sides is recommended, rather than insemination with a lot of sperm of the uterine horn on one side.
