Embryos transfer

Embryos transfer

DEFINITION

• Embryo transfer is an artificial method of breeding whereby newly formed embryos prior to implantation are removed from a female animal and transferred into the reproductive tract of another female of the same species where they develop to term.

STEPS

• Superovulation:
• Insemination:
• Embryo Recovery:
• Embryo Evaluation:
• Recipient Preparation:
• Embryo Transfer:
• Pregnancy Monitoring

Superovulation

• Hormonal Treatment:
• The process typically starts with administering Follicle Stimulating Hormone (FSH), which promotes the development of multiple follicles in the ovaries.
• This is often combined with Gonadotropin-Releasing Hormone (GnRH) to induce a surge of Luteinizing Hormone (LH), triggering ovulation.
• The regimen usually spans about 4-7 days, and doses are adjusted based on the donor’s response.
• Monitoring:
• Ultrasound imaging is used to monitor ovarian follicles. The size and number of follicles are assessed to determine the optimal time for insemination.

Insemination

• Artificial Insemination:
• This can be performed transcervically, using a catheter inserted through the cervix, or laparoscopically, where a surgical approach is taken.
• Timing is critical; insemination should occur about 12 hours before ovulation for optimal fertilization.
• Semen is usually collected from a male with desirable traits and may be frozen or used fresh.
• Semen Preparation:
• Semen may be processed to remove non-motile sperm and other components, improving the chances of successful fertilization.

Embryo Recovery

• Timing:
• Embryo recovery is typically performed 6-8 days post-insemination, when embryos are at the blastocyst stage.
• Flushing Procedure:
• A sterile saline solution is introduced into the uterus through a catheter.
• After the solution is flushed, it is collected in a sterile container.
• The embryos are filtered from the flush solution using nylon mesh or gauze to retain them while removing excess fluid.

Embryo Evaluation

• Quality Assessment:
• Embryos are examined under a microscope for developmental stage, size, and overall morphology.
