In the IVF treatment, the embryos should be of good quality for transfer to be successful. The rate of success depends on the embryo’s quality.
So, the fertility specialist will use a grading system to identify and finalize the embryo for the treatment process. The grading system can play a vital role in analyzing the success rate of embryo transfer.
It might differ in the various fertility clinics. The grade shows whether an embryo is good to transfer or not or whether you should choose another fertilized egg.
The average success rate of pregnancy with 2AB embryo
The average success rate of pregnancy cannot be told to match all the clinics. It may differ with some of the factors and reasons. But, in general, you can have a grading system like:
Excellent ( 3AA or higher): 60-70% of success rate.
Average (4BB or 2AB): 40-50% of success rate.
Poor grades also mean a lower chance of success. This is a general information only. You can consult your doctor, who will give you the appropriate grade result for the embryo.
The two different reasons which may vary on the grades:
- Clinic-specific grading system
- Limited data on variations
The Gardner grading system might vary for these reasons.
Factors Affecting Success Rates with 2 AB Embryo Transfer
Five important factors can affect the success rate of 2AB Embryo transfer:
- Age of the mother
- Underlying medical conditions
- Number of embryos transferred (single vs. multiple)
- Quality of the uterine lining
- Other factors specific to each patient
Age of the mother
- Women who are under the age of 35 have a higher number of healthy eggs, and there is a high rate of implantation success including the 2AB-graded ones.
- In the 2AB grades, the fertility rate and egg quality start decreasing for women aged above 35.
Underlying medical conditions
- Particular medical conditions can impact embryo transfer. It might also affect pregnancy development. It includes endometriosis, uterine fibroids, & uncontrolled thyroid issues. If the problems or symptoms are addressed prior, it can help to improve the rates of success chances.
Number of embryos transferred (single vs. multiple)
- Single embryo transfers:
There is no chance of twins or triplets. However, the chances of pregnancy success can be reduced due to only one embryo being transferred.
- Multiple embryo transfers:
There is a high chance of success rate. Remember, you will have to face simultaneously the high rate of twins or triplets.
The number of embryos can be suggested by the specialist according to your age, embryo quality, including 2AB, and your preferences, which also takes place when the number of embryos is chosen.
Quality of the uterine lining
- A 2AB embryo depends on factors like hormonal imbalance or thin lining, which can cause less implantation.
- Also, a healthy endometrium is crucial for embryo success rate.
- Maintain a healthy endometrium, and if there is any issue, figure it out and solve it with your doctor’s guidance to improve your chances.
Other factors specific to each patient
- Lifestyle factors such as smoking, obesity, or alcohol consumption can affect the rate of pregnancy.
- If you find these factors and make the appropriate changes can help you to improve the rate of success including 2AB embryo.
Conclusion
The above-said 2AB embryo success rates are for your general information. You must visit your fertility clinic for an accurate result. However, 2AB might give you an average success rate of 40-50% of the conception rate.
Remember, your rate of success completely depends on your embryo quality, age, lifestyle changes, hormonal factors, etc.,
According to research, the general informational study says the embryo’s average success rate is 40-50% if the grade is 2AB or 4BB.
This is only the example, not the accurate result. Visit your doctor to have a specific result of the success rate.
Some factors can affect 2AB embryos, like the age of the mother, the number of embrys transferred, the quality of uterine lining, and medical conditions.
Among these, any issue can impact conception, but if you figure out and make the necessary changes, the success rate will increase.
