The embryo success rate is the key to the success of IVF treatment. Its quality defines the high rate of conception. Based on the embryo quality, your IVF journey can be started.
Embryo quality of 3ab grade is a “good” embryo using the most common Gardner grading system for embryos. The grade 3ab is said to have about 60% chance of success. But, this may be changed, based on several factors.
In this article, you will learn about the average success rate, how success rate can affect various factors, and the positive aspects of the 3ab embryo.
The average success rate of pregnancy with 3AB embryo
The average success rate can depend on several factors. The human body is not the same for all, right?
Likewise, if you are undergoing IVF treatment, firstly doctors will diagnose your body and suggest a suitable treatment process.
The success rate of the embryo also differs by person. It may depend on your age, hormonal changes, or medical condition. A 3AB embryo is said to have good-grade blastocysts, and the pregnancy rate is about 53-55%.
The average success rate is not assured as this is just general information. You need to consult with your fertility doctor for an accurate analysis.
Factors determining the success rate of a 3AB embryo
3ab embryo success rate can depend on various factors. Some of the key influences are listed below:
Age:
Age can play a vital role in pregnancy, especially in IVF treatment. The quality of the egg diminishes throughout the aging cycle.
Women who are above the age group of 35 have only limited or unhealthy eggs, which can lead to fewer chances of implantation rates for embryos, including those with 3AB grades.
Whereas, women who are under the age of 35, have healthy eggs as well and the rate of success is also high, for any embryo including 3AB grades.
Underlying medical conditions:
Some of the medical conditions like endometriosis, uncontrolled thyroid issues, and uterine fibroids can affect the implantation or pregnancy.
It is advised you find out the issues, make sure to diagnose the condition by your specialist, and get it treated.
Number of embryos transfers:
The number of embryos must be considered as an affecting factor, if there are single transfers, there will be fewer chances of success rate.
If two or more embryos are transferred, the chances of twins or triplets are as high as the rate of conception.
The positive aspect of a 3AB embryo
- The 3ab grade embryo is considered good quality and is ready for the process of implanting in the uterus lining.
- This grade indicates the well-developed blastocysts. It is the crucial stage for embryo development and successful implantation.
- As the 3 indicates the fully expanded blastocyst, A means (ICM) Inner Cell Mass is the good quality cells that are crucial for fetal development.
- B means trophectoderm (TE) – is a moderately packed cell which is the positive sign of embryo quality.
Conclusion
The 3ab embryo has a good success rate, however you need to confirm this with your fertility specialist. It is also said to have a higher chance of success rate compared to lower grades.
This can be based on individual factors like age, number of embryo transfers, and some medical conditions, uterine line quality. But, consult a doctor for the grade identification and result.
The study says a 3ab embryo is a good quality embryo, the pregnancy success rate in general was 53-55%. However, the estimation is not the same for all and is not guaranteed. Consult your doctor to identify the quality of the embryo for further treatment.
Yes, 3AB embryo is a good grade. Grade 3 indicates the fully expanded blastocysts, ‘a’ means (ICM) inner cell mass, and ‘b’ means (TE) trophectoderm.
However, the embryo quality may vary based on the age, hormones, health conditions, uterine lining, etc.,
In general, the grade 3ab is calculated as 53-55% of chances of success. But, in the clinic, doctors will analyze the grade, and give you the result based on the data and experience.
