title: Implantation in both of the uterine horns after the unilateral intrauterine insemination in rabbits.
abstract: Artificial insemination was carried out by injecting semen into the upper part of the left uterine horn in rabbits with a duplex uterus. Ovulation was then induced by administration of hCG. As a result, implanted fetuses were observed not only in the left uterine horn but also in the right uterine horn. However, when similar insemination was carried out after ligation of the right utero-tubal junction, fertilization did not occur in the right oviduct. From these finding, we conclude that some of the spermatozoa injected into the left uterine horn was discharged into the vagina, entered the right uterine cervical canal, and reached the right oviduct to fertilize the ova.
