The efficiency of the Improved Genome Editing via Oviductal Nucleic Acids Delivery (I-GONAD) method is comparable to traditional microinjection, which requires zygote collection from donor females and transfer to pseudo-pregnant females. This protocol demonstrates its effectiveness by introducing CRISPR/Cas9-induced mutations into the ROSA26 locus on chromosome 6.

This video describes the technique of transferring embryos into the oviduct of a recipient female rabbit via Laparoscopy. It allows embryo remodeling in rabbits during its migration through the oviduct, eventually helping in successful implantation. This technique can also be used for stored embryos with good efficiency.

A method for microdissection of the mouse oviduct that allows collection of the individual segments while maintaining RNA integrity is presented. In addition, non-enzymatic oviductal cell dissociation procedure is described. The methods are appropriate for subsequent gene and protein analysis of the functionally different oviductal segments and dissociated oviductal cells.

FAQs
Maintaining the relationships among the infundibulum, ampulla, and isthmus allows observations to remain connected to the tract’s functional organization. If these regions are separated without preserving their arrangement, researchers may lose important anatomical context. Careful preparation therefore supports more reliable comparisons between reproductive tract structure and processes such as gamete transport or early embryo movement.
The method makes the oviduct’s tissue organization directly observable rather than leaving its role as an abstract description. Examining identifiable regions in relation to one another helps students and researchers interpret how reproductive anatomy supports transport-related functions. This anatomical perspective is especially useful when studying fertility, reproductive development, or changes associated with experimental conditions.
Comparing specimens can show whether an experimental condition is associated with visible changes in oviduct organization or regional structure. These observations provide anatomical context for investigating altered fertility, embryo transport, or reproductive development. The comparison is most informative when tissues are examined under consistent conditions and the structural relationships among regions are preserved during preparation.
A basic workflow consists of exposing the reproductive tract, carefully isolating the oviduct, separating it from surrounding tissue under controlled conditions, and examining its identifiable regions. The infundibulum, ampulla, and isthmus can then be recognized while their arrangement is preserved. This sequence supports systematic anatomical examination without losing the relationships needed for interpretation.
Controlled handling and careful tissue separation are central preparation requirements described for this method. The oviduct must be exposed and isolated without unnecessarily disrupting its regional arrangement, so the infundibulum, ampulla, and isthmus remain interpretable. Attention to these conditions improves the value of observations used to relate tissue organization to reproductive function.
This approach is useful when learners or researchers need to examine reproductive anatomy directly, compare normal and experimentally altered specimens, or investigate links between structure and reproductive outcomes. Its applications include studies of fertility, embryo transport, reproductive development, and disorders affecting the female reproductive system. It also helps connect anatomical observations with broader biological questions.
