2025
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.

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.

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.

The microinjection of mouse oocytes is commonly used for both classic transgenesis (i.e., the random integration of transgenes) and CRISPR-mediated gene targeting. This protocol reviews the latest developments in microinjection, with a particular emphasis on quality control and genotyping strategies.
FAQs
Transport in the oviduct ampulla depends on two coordinated systems: epithelial cilia beat to help move contents, while smooth-muscle contractions propel and regulate movement through the tube. Their combined action affects the position and timing of sperm, oocytes, and early embryos, making transport a functional part of reproductive success.
Epithelial secretions help establish and maintain the local conditions needed for gamete interaction and initial development. This means the ampulla is not merely a passageway: its lining contributes to the environment in which sperm and oocytes can interact and in which early embryos begin their transit. Changes to these conditions may therefore influence fertility outcomes.
Within this region, successful fertilization depends on more than bringing gametes into the same location. The specialized tubal environment supports sperm-oocyte recognition, while coordinated movement helps align reproductive timing. Studying these linked processes can clarify how transport and cellular interaction work together before the early embryo continues through the oviduct.
Research on the oviduct ampulla can connect cellular events with whole-tube function. Investigators can examine sperm-oocyte recognition, ciliary and muscular transport, epithelial support, and the movement of early embryos as related processes. This integrated view helps identify whether a reproductive problem reflects altered interaction, disrupted transport, or changed tubal conditions.
Disrupted ampullary function may affect fertility in several ways, including impaired movement of gametes or embryos and altered conditions for fertilization. This makes the region relevant to infertility research and to studies of ectopic pregnancy, where abnormal tubal transport is an important context. The ampulla therefore links basic reproductive biology with clinically significant outcomes.
Researchers also examine the ampulla in reproductive toxicology and assisted reproductive technologies. These applications focus on how altered tubal conditions or transport may affect fertility outcomes and fertilization-related events. Findings can help interpret why conditions within the oviduct matter when researchers investigate gametes and embryos.
