Индуцирование ложной беременности у самок мышей без необходимости вазэктомии самцов перед нехирургическим переносом эмбрионов или искусственным оплодотворением

Executive Industry Relevance

Efficient induction of pseudopregnancy in female mice is critical for scalable, reproducible assisted reproduction workflows in preclinical research. The standardized cervical manipulation technique eliminates the need for vasectomized males, streamlining vivarium operations and supporting the 3Rs principles. This advancement enhances the reliability and predictability of generating pseudopregnant recipients for embryo transfer and artificial insemination, directly impacting resource allocation and experimental throughput.
