Is 9 Eggs Good for IVF? The Ultimate Fertility Guide

IVF, or in vitro fertilization, is a process in which eggs and sperm are combined outside of the body in a laboratory setting. This procedure is usually recommended when other fertility treatments have proven unsuccessful. IVF is a complex process that involves several steps, one of which is the retrieval of eggs. In this article, we will explore how many eggs to aim for in IVF, specifically, whether 9 eggs is a good number to have.

Understanding Egg Retrieval in IVF

The first step in IVF is to stimulate the ovaries to produce multiple eggs through the use of hormones. The eggs are then retrieved from the ovaries, usually around 36 hours after the final hormone injection. During the retrieval process, a needle is used to remove the eggs from the ovary. These eggs are then fertilized in a laboratory, and once they have grown into viable embryos, one or more embryos are transferred back into the uterus.

It is essential to retrieve a good number of eggs in IVF to increase the chances of fertilization and viable embryos. However, the number of eggs required is dependent on several factors. Some of these factors include age, ovarian reserve, and medical history. Therefore, discussing with your doctor is necessary to determine the optimum number of eggs to aim for.

Is 9 Eggs Good for IVF?

The number of eggs that doctors consider ideal in IVF varies depending on various medical factors. However, research indicates that having at least nine eggs during egg retrieval increases the chances of success in IVF. A study conducted in 2015 revealed that patients who had at least nine eggs collected during retrieval had higher rates of live births and viable pregnancies.

Although nine eggs are a good starting point, it is essential to remember that this number may vary depending on other factors, such as age and medical history. Your doctor will recommend the number of eggs you need to aim for that will maximize your chances of success in IVF.

The Role of Age in IVF Success

The age of a woman is a critical factor that affects the success rates of IVF. Usually, ovarian reserve declines with age, so women who are older may have fewer eggs available during retrieval. For example, a woman who is 35 years old may have approximately 10% of her original ovarian reserve, meaning that she may produce fewer eggs than a younger woman. Therefore, women over the age of 35 may be required to produce more eggs to achieve a successful outcome in IVF.

Ovarian Reserve in IVF

Ovarian reserve is a medical term that describes the number of eggs a woman has left in her ovaries. Having a high ovarian reserve is beneficial in increasing the chances of success in IVF. Women who have a low ovarian reserve may require higher doses of hormones to stimulate their ovaries to produce more eggs. A low ovarian reserve may also lead to a decrease in the number of eggs retrieved during the procedure.

Factors That Affect IVF Success Rates

The number of eggs is not the sole factor that affects the success of IVF. Several other factors influence the outcome of the procedure. These factors include:

  • The age of the woman
  • The quality of the eggs collected
  • The success of the embryos in vitro
  • The success of implantation back into the uterus
  • The use of donor eggs or sperm

The success of IVF is a result of multiple factors, and having a good number of eggs alone does not guarantee success.

What Can You Do to Boost IVF Success?

Several measures may be taken to boost the chances of a successful IVF outcome. Some of these measures include:

  • Implementing a healthy lifestyle to improve general health and fertility
  • Avoiding smoking and reducing alcohol intake
  • Reducing stress levels
  • Ensuring the eggs retrieved are of good quality
  • Using the best treatment protocol available


Having at least 9 eggs retrieved during IVF is generally considered a good sign and may increase the likelihood of success. However, the ideal number of eggs varies depending on several factors unique to each individual. It is essential to discuss with your doctor the optimum number of eggs to aim for in IVF.
