Conventionally, in order to "produce offspring from transplanted fertilized eggs", it was required to create pseudopregnant females by vasectomized males.
"Pseudopregnant mouse and rat production device ~EGET~" does not require a vasectomized male, achieves artificial pseudopregnancy induction.
This method enables the production of spawn from transplanted fertilized eggs in a compact, and simple operation. It is expected to reduce the number of animals used and the time required.
In addition, pseudopregnant animals can be produced on the day of transplantation.
It can also be used as a backup for conventional methods.
