On average, the success rate for IVF depends on the patient’s age, previous pregnancies, type of fertility problems, status of male fertility , lifestyle habits and other physiological factors. The potential mother has to go through a comprehensive physical examination and examination of the eggs reserve is especially important. It might be 50-60 percent in women under thirty-five or 10 percent in women over forty-three.
The success rate also depends on technical factors such as the doctor’s training and experience and quality control of the fertility center. A selected fertility clinic should be the one which is able to maintain the average success rate while at the same time doing their best for individual patients.
Egg retrieval for IVF
Every fertility clinic has their own set of protocol on how they conducted the IVF and egg retrieval procedures. In general, it you are planning to go through with IVF, you should focus on your physical health and conscientiously follow the doctor’s advice.
In some patients, the doctor can only manage to retrieve a small amount of eggs which is not ideal for IVF because the more eggs that are successfully retrieved, the better the chance of having a successful fertilization will be. However, getting fewer eggs does not necessarily mean that the IVF won’t be successful. As long as the quality of the retrieved eggs are good, the success rate is very high.
Why do some women only release a few eggs?
- Age is an important factor. Older women above the age of 40 have declining ovarian function and therefore won’t be able to release as many eggs. Some infertile young women whom suffer from impaired ovarian function due to some diseases would also face the same issues.
- It takes between 35-36 hours for the eggs to be fully matured after the final medication known as the “trigger” shot is given. The “trigger” shot is the last injection the woman receives after ovulation until the time for egg retrieval and functions to promote the egg maturation, easier release from the ovary as well as retrieval.
- The follicles are monitored by ultrasound during the ovulation period. The doctors can identify how many eggs are maturing. However, they cannot determine the quality of the maturing eggs.
- The quality of follicles is often related to your genes. If there are chromosomal problems, or some genetic problems then there may be a lot of empty follicles, and even the quality of the eggs taken out might not be good.
There are many reasons that will cause the release of fewer eggs, and these are usually related to the age and health of the reproductive organ. Therefore, it is always best to get pregnant at the right age, exercise regularly, maintain a healthy and balance lifestyle, and cooperate with your doctors to help address any problems that you might have.
