Abstract/OtherAbstract:

A quantitative method was used to determine whether the spermatozoa of foreign species could pass through the uterotubal junction (UTJ) of the hamster as efficiently as homologous (hamster) spermatozoa. Estrous female hamsters were artificially inseminated with epididymal spermatozoa of homologous and heterologous (foreign) species. The number and distribution of spermatozoa in the oviduct were determined several hours after insemination (shortly before ovulation). The passage of immotile (dead) hamster spermatozoa through the UTJ was also examined. It was found that the spermatozoa of all foreign species tested (rat, mouse, guinea pig, and rabbit), as well as immotile hamster spermatozoa, could pass through the UTJ but did so in much smaller numbers compared to live hamster spermatozoa. This was not specifically due to poor survival of foreign spermatozoa in the hamster uterus, as the viability of all inseminated spermatozoa (including hamster spermatozoa) was considerably reduced by 1 h after insemination. While a large number of live hamster spermatozoa were distributed throughout the caudal isthmus at the time of examination, none or only a very few foreign spermatozoa had advanced this far. The few foreign and immotile spermatozoa that reached the caudal isthmus were confined to the first ascending loop of this segment. Some possible causes for the small number and retarded advance of foreign spermatozoa in the hamster oviduct were discussed. |
