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.

A method of gene transfer into chicken embryos at later incubation stages (older than Hamburger and Hamilton stage (HH) 22) is described. This method overcomes disadvantages of in ovo electroporation applied to older chicken embryos and is a useful technique to study gene function and regulation at older developmental stages.

Utero-tubal embryo transfer uses the utero-tubal junction as a barrier to prevent the embryo outflow that may occur when performing uterine transfer. Vasectomized males are required to obtain pseudopregnant recipients for embryo transfer. Both techniques are discussed.

We demonstrate a method for grafting cultured cells into defined sites of early mouse embryos to determine their in vivo potential. We also introduce an optimized electroporation method that uses glass capillaries of known diameter, allowing the precise delivery of exogenous DNA into a few cells in the embryos.
FAQs
Hormonal preparation helps synchronize the recipient’s reproductive cycle with the developmental stage of the embryo. This timing places the embryo in a uterine environment that is biologically suitable for continued development. In human assisted reproduction, synchronization is therefore important because the embryo must encounter an appropriately prepared endometrium when it is deposited.
The endometrium, the lining of the uterus, provides the tissue in which the embryo may implant after transfer. Its condition contributes to whether development can continue within the uterus. Embryo transfer therefore connects laboratory-supported early development with the biological processes required for implantation and subsequent reproductive progression.
The intended outcome is that the embryo remains in a suitable reproductive environment, implants in the endometrium, and continues developing. Transfer does not itself guarantee implantation or ongoing development. Instead, it places the early embryo at the anatomical site where these later biological processes may occur.
In human assisted reproduction, clinicians use a thin catheter to place the embryo through the cervix and into the uterine cavity. The procedure follows preparation of the recipient’s reproductive cycle when hormonal synchronization is used. After deposition, the embryo remains in the uterus, where implantation may occur in the endometrium.
Embryo transfer is used in in vitro fertilization, fertility preservation, and some fertility treatments. In these settings, it provides a route for placing an early embryo into the reproductive tract so development can continue in a suitable biological environment. The specific context differs, but each application depends on subsequent implantation and development.
Beyond human fertility treatment, related embryo-transfer procedures support animal breeding and research. The technique can help study implantation and early development while also improving the reproductive use of valuable embryos. These applications make it possible to examine early biological processes and use selected embryos more effectively within reproductive programs.
