title: Recent advances in the microinsemination of laboratory animals.
abstract: Microinsemination techniques were applied to laboratory animals, including mice, Mongolian gerbils, mastomys, guinea pigs and cynomolgus monkeys. After micro-insemination with spermatozoa or round spermatids, their oocytes were successfully fertilized and subsequently developed into 4-cells to blastocysts, depending on species. The efficiencies of microinsemination techniques for producing fertilized oocytes were comparable with, or superior to those of IVF in these species.
