What is Egg Retrieval in IVF Treatment?
Egg retrieval is a medical procedure in which a fertility specialist collects mature eggs from a follicle. A follicle is a mature egg container in a woman’s ovaries. The doctors collect eggs and surrounding fluid using a thin needle( Aspiration needle). Then, the retrieved egg and fluid are moved to the test tube from the needle.
The oocyte retrieval is a crucial procedure in assisted reproductive technologies, such as in vitro fertilization (IVF).
The egg extraction process takes about 30-60 minutes.
Why is egg retrieval done?
Here’s a closer look at the reasons why egg retrieval is performed:
1. IVF Treatment
For couples or individuals undergoing IVF, egg retrieval is an essential first step. It allows healthcare professionals to collect mature eggs from the ovaries. These eggs are then fertilized with sperm in a laboratory to create embryos. The healthiest embryos are then selected for implantation into the uterus, potentially leading to pregnancy.
2. Egg Freezing for Future Use
Egg collection isn’t just for immediate pregnancy attempts. Some individuals choose to undergo an egg extraction process to freeze their eggs (egg freezing) or embryo freezing.
This can be a valuable option for those who:
- Are not yet ready to start a family but want to preserve their fertility for the future.
- May experience a decline in egg quality or quantity due to age or medical conditions. Freezing eggs at a younger age can offer more options for future IVF cycles.
3. Egg Donation
Egg retrieval also plays a vital role in egg donation. These donated eggs can then be used by individuals or couples facing infertility due to various factors, such as premature ovarian failure or poor egg quality. Egg donation allows them to pursue their dream of parenthood through IVF.
How does Egg Retrieval process start?
The process starts with reviewing your medical history, physical examination, blood test, and ultrasound monitoring.
Let’s understand it in detail.
Medical History Review
This in-depth discussion focuses on your overall health and reproductive history.
You’ll likely discuss:
- Past surgeries or illnesses.
- Current medications and supplements.
- Menstrual cycles (length, regularity, flow).
- Previous pregnancies, miscarriages, or terminations.
- Your partner’s medical history may also be reviewed, including any potential risk factors for male infertility.
2. Physical Examination:
A physical exam allows the doctor to assess your overall health and identify any potential underlying conditions that might affect fertility.
This may involve:
- A general physical exam to check for any abnormalities.
- A pelvic exam for women to evaluate the uterus, cervix, and ovaries.
3. Blood Tests
Blood tests measure hormone levels that play a critical role in ovulation, egg quality, and sperm production.
Common hormone tests might include:
- Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) to assess ovarian function.
- Estrogen and progesterone to understand ovulation timing.
- Thyroid-stimulating hormone (TSH) to rule out thyroid problems that can impact fertility.
- Testing for sexually transmitted infections (STIs) that can affect fertility if left untreated.
4. Ultrasound Monitoring
Ultrasound helps to visualize detailed images of reproductive organs.
- The size and shape of the uterus and ovaries.
- The presence of uterine fibroids or blockages in the fallopian tubes.
- The number of follicles (potential egg sacs) in the ovaries.
After all these necessary tests, reviews, and monitoring the doctors know your overall reproductive health and make a treatment plan.
The next step is to prepare your body for the egg retrieval process.
Preparing your body for the egg retrieval Process
If you’re not ovulating regularly or have low egg production, ovarian stimulation medications are recommended. These medications help stimulate the ovaries to produce more eggs.
After the use of medications:
- Regular transvaginal ultrasounds are done.
- Hormone Level Tests are done.
- And, you will get a trigger injection 34-36 hours before the egg retrieval procedure.
What happens during egg collection day?
During egg collection day, a high-resolution ultrasound probe is inserted into the vagina to see the ovaries and follicles. Then, a thin needle is inserted through the vagina and into each follicle to collect the fluid containing the eggs. The collected eggs are transferred to a lab for further processing.
Are there risks associated with the egg retrieval process?
Egg retrieval is generally considered a safe procedure but there are certain risks and potential complications associated with it. Patients undergoing this procedure may experience discomfort or pain during and after the procedure. Understanding these risks can help patients make informed decisions and take necessary precautions.
What is a good result from egg retrieval?
The fertility specialists typically aim to retrieve 8 to 15 mature eggs. Younger women with a healthy ovarian reserve might have a higher number of retrieved eggs compared to women with diminished ovarian reserve or undergoing IVF at an older age.
While having a sufficient number of eggs is important, the quality of those eggs also matters.
So, Quality Oocyte Identification is done to increase the chance of fertilizing with sperm and developing into healthy embryos.
Egg retrieval Timeline
Doctors usually collect eggs from the ovaries about 10 to 12 days after giving hormone medications. The medications help the ovaries make more eggs.
The exact Gamete collection day depends on your follicular growth and egg development. It is monitored through ultrasound and bloodwork.
Recovery
Recovery is generally minimal due to the minimally invasive nature of the surgery.
Risks are relatively low, including bleeding, infection, and rare damage to the bowels or bladder.
