Transvaginal Oocyte Retrieval (Egg Retrieval) for In Vitro Fertilization (IVF)
What is Transvaginal Oocyte Retrieval (TVOR)?
TVOR, also known as egg retrieval, is a procedure used in IVF to collect eggs (oocytes) from the ovaries. These eggs will then be fertilized with sperm outside the body in a laboratory setting.
When is the procedure performed?
Egg retrieval occurs after the follicles containing the eggs have reached maturity. This is typically determined through ultrasound measurements and hormone tests.
What happens during the procedure?
- Anesthesia: You will receive medication (anesthesia) to ensure the procedure is painless.
- Egg aspiration:
- A thin needle is inserted into the vagina and guided by ultrasound to reach the ovaries and follicles.
- The fluid within the follicles is gently suctioned out, carrying the eggs with it.
What happens after the procedure?
- The eggs are sent to the IVF lab for further processing.
- You will be monitored in a recovery room for several hours before being discharged, typically within 2-3 hours.
- Your partner will be asked to provide a sperm sample the next day for fertilization.
