BLASTOCYST TRANSFER STUDY IN THE SENESCENT GOLDEN HAMSTER

Summary.: Blastocysts and late morulae were flushed from the uteri of young female donors (3- to 6-month-old) at 62 to 67 hours after ovulation and were transferred to the uteri of young (4- to 6-month-old) and senescent (14-to 15-month-old) pseudopregnant female hamsters 62 to 67 hr, 86 to 91 hr, or 110 to 115 hr after ovulation The highest percentage of ovum implantation and the greatest number of females with implantation sites were noted in the young female after ova were transferred 62 to 67 hr after ovulation and in the senescent female following transfers 86 to 91 hr after ovulation. This indicates a possible delay in uterine receptivity to blastocyst implantation in the senescent hamster and may contribute to the reduction in litter size noted in the senescent female.
