How Many Eggs Are Retrieved for IVF?
The amount of eggs retrieved in an IVF cycle will largely depend on a variety of factor such as age, amount of medication and ovarian reserve. The optimal number of eggs retrieved based on research is 4-15 eggs for women under 35. Age matters greatly during IVF because as a woman ages, the number of eggs required increases.
The egg quantity and egg quality are different things, with egg quality referring to an eggs ability to be fertilized, grown into a healthy embryo and result in a successful pregnancy. This means that good quality eggs often have a better chance of fertilizing and developing normally, with the resulting embryos most likely to implant.
Although it’s impossible to guarantee a specific number of eggs retrieved, there are some things you can do to maximize the chances of higher egg retrieval such as:
-
Eating a well-balanced diet
-
Exercise Regularly
-
Keep Body Mass Index (BMI) Within a Healthy Range
-
Cut Back on Smoking
-
Avoid Alcohol
Side Effects of Egg Retrieval
Although egg collection procedures are generally low risk and minimally invasive, there are some side affects you may experience due to the nature of the procedure. Side effects of egg retrieval may include:
-
Bloating or feeling full
-
Light spotting
-
Feeling constipated
-
Cramping
We know that it can be difficult managing the symptoms associated with egg retrieval. Having a strong support system in place and getting rest will help with managing these side effects.
Wondering About the Embryo Creation Process?
How Attrition Rate is Calculated
When you’re beginning the IVF process, one thing to remember is that not every embryo will progress through the necessary stages to implant and create a baby. The IVF attrition rate and means that viable eggs/embryos will slowly taper off once they’re in the lab. This is normal and often happens to every patient.
The number of eggs retrieved isnt always going to result in an equal number of mature embryos. Instead, the number will gradually decrease as the embryos go from retrieved egg to fertilization and through various growth stages.
Below is how attrition rates are typically calculated:
-
80% of eggs retrieved will be mature
-
80% of the mature eggs will fertilize
-
Roughly 40% of the fertilized eggs will reach the blastocyst stage.
What is a Blastocyst?
A blastocyst is an early-stage embryo that forms about five to six days after fertilization. An embryo that makes it to the blastocyst stage used in IVF has a high chance of resulting in a successful pregnancy.
Below, using the percentages above, we’ve calculated the estimated attrition rate of how many embryos may result from a specific amount of eggs retrieved.
• Eggs that are mature: 1-2 • Eggs that will fertilize: 1-2 • Day 5 embryos: 0-1 • Eggs that are mature: 2-3 • Eggs that will fertilize: 1-2 • Day 5 embryos: 0-1 • Eggs that are mature: 3-4 • Eggs that will fertilize: 2-3 • Day 5 embryos: 1-2 • Eggs that are mature: 4 • Eggs that will fertilize: 3-4 • Day 5 embryos: 1-2 • Eggs that are mature: 4-5 • Eggs that will fertilize: 4 • Day 5 embryos: 1-2 • Eggs that are mature: 5-6 • Eggs that will fertilize: 4-5 • Day 5 embryos: 2 • Eggs that are mature: 6-7 • Eggs that will fertilize: 4-5 • Day 5 embryos: 2 • Eggs that are mature: 7-8 • Eggs that will fertilize: 5-6 • Day 5 embryos: 2-3 • Eggs that are mature: 8 • Eggs that will fertilize: 6-7 • Day 5 embryos: 2-3Egg Retrieval Success Rates [2-10 Eggs]
• Eggs that are mature: 10-11 • Eggs that will fertilize: 8 • Embryos for transfer: 3-4 • Eggs that are mature: 14-15 • Eggs that will fertilize: 11-12 • Day 5 embryos: 4-5 • Eggs that are mature: 20 • Eggs that fertilize: 16 • Day 5 embryos: 6-7 • Eggs that are mature: 28-29 • Eggs that fertilize: 23-24 • Day 5 embryos 9-10Egg Retrieval Success Rates [11-40 Eggs]
Your Next Steps
The number of eggs retrieved during an IVF cycle can greatly impact the chances of success. While factors such as age and egg quality also play crucial roles, retrieving a higher number of eggs generally increases the probability of achieving a successful pregnancy.
For the best outcomes, working closely with a fertility specialist can help tailor the treatment to your specific needs. We know that your journey to parenthood has been an emotional rollercoaster. With this guide, you’ll be on the right track toward understanding egg retrieval success rates and creating the family you’ve always dreamed of.
