This question arises: how many embryos do you get from IVF? In a study of over 125,000 in vitro fertilization procedures, researchers compared the outcomes for women under 40 to those for older women in one of the most comprehensive investigations ever. The finding that there is no medical justification for transferring three or more embryos, even in women over 40, has major consequences in the United States, where 1 out of 3 IVF procedures involves transferring more than two embryos. So how many embryos are made in IVF?
How many eggs fertilized IVF?
One of the most common questions is: what percentage of eggs fertilize in IVF? IVF has been called one of the most significant medical achievements of the 20th century. More than 5 million children have been born using this technology, which is currently being used in over 100 countries.
It is important to understand how many eggs fertilized IVF? What is the ultimate objective of IVF treatment? A clinical pregnancy is the primary goal. Initially, clinicians transferred too many embryos, hoping that at least one of them would successfully implant and give a favorable pregnancy outcome. However, as time went on and expertise and knowledge in the subject increased, it became apparent that the outcome was related to the number and quality of embryos available for transfer rather than the quantity of embryos transferred.
There are a lot of questions that any couple undertaking or planning IVF has on their minds. The process, the time required, the financial requirements, and what they must do to achieve success, for example, are just a few of the many questions that burden their minds. Everyone wonders about the number of embryos produced in an IVF treatment cycle. There is no set answer for this query because the quantity of embryos produced in an IVF treatment cycle is determined by a variety of factors. Every patient is unique, just like no two people are the same.
The quantity of embryos created during an IVF procedure is heavily dependent on the quantity and quality of eggs or oocytes, as well as the sperm count and its morphology. Other important factors include the age of the man and woman, how women respond to hormonal stimulation, the quantity of eggs produced through hormonal stimulation, body mass index, and other systemic and lifestyle factors.
A woman's age has a significant impact on the number of embryos that are formed. The number and quality of eggs that are collected are the most critical factors. After 35 years old, the quantity and quality of eggs decrease in women. The woman's age has a significant impact on the quantity of eggs collected in ovarian stimulation and the number of eggs produced. As a woman's age increases, ovarian reserves decline, and the likelihood of producing good quality embryos decreases. A decrease in the quantity of eggs produced in polycystic ovarian syndrome (PCOS) may increase the likelihood of developing more embryos. However, the quantity of eggs may increase and the quality may be compromised, resulting in poor quality embryos or no embryos at all.
What percentage of eggs fertilize in IVF?
So what percentage of eggs fertilize in IVF? Between 70-85% of patients usually have 70-85% of their mature eggs fertilized. In standard IVF, immature eggs cannot be injected and will not fertilize. In these instances, the fertilization may be lower than usual because the eggs are of poorer quality or the sperm is of very low quality.
How many embryos do you get from IVF?
All eggs do not mature at the same rate during ovarian stimulation, so we must time oocyte retrieval such that we obtain the greatest number of mature eggs. Mature eggs are more likely to develop into viable embryos than young eggs that may not fertilize at all, therefore we should be more concerned with the timing of oocyte retrieval.

It is important to know the cause of infertility in order to predict the number of embryos formed in each IVF cycle, as this quantity will always be unique for each patient. Age and ovarian reserve are among the causes of infertility.
We hope we were able to answer the question: how many embryos do you get from IVF?
