IVF is one of the most successful assisted reproductive technologies available today. IVF, or In-Vitro Fertilization, is a technique where both the eggs of the female and male sperm are retrieved and combined in a laboratory. Fertilization occurs outside the human body. Once fertilization is successful, it is transferred onto the woman’s uterus.

IVF success rates vary depending on many factors, many of which are discussed in this article; however, specific medical options and lifestyle changes can play a part in improving these rates. IVF treatments have undergone numerous changes in recent years, and we now have more research and data available to us to determine what factors contribute to IVF success.

Many factors have the ability to affect the likelihood of success of an IVF procedure. If these are correctly discussed with your doctor, valuable guidance can be derived, and your chances of success may be higher.


Our bodies are naturally more receptive to pregnancy attempts in certain age ranges. However, there is no reason to be discouraged from undergoing IVF if you are outside the optimal age range. Generally, women between the ages of 24-34 are believed to have the highest chances of IVF success.

As per SART data, the percentage of live births through IVF in 2020 was:

– Under 35 years: 44.6%
– 35-37 years: 31.5%
– 38-40 years: 19.9%
– 41-42 years: 9.7%
– More than 42 years: 2.9%

Hence, age plays a pivotal role in IVF success rate. However, appropriate self-care, along with modern medical advice and technology, can significantly increase your chances of conception even if you have crossed the above-mentioned age limits.


Lifestyle habits also play a part in deciding the likelihood of success of IVF. For both men and women, consumption of alcohol and smoking are both strongly discouraged. Women trying to conceive naturally or through IVF should steer away from consuming alcohol. The British Fertility Society states that a lady should stop alcohol consumption at least three months before IVF.

In addition, couples trying to conceive through IVF should focus on reducing psychological stress, which is found to affect IVF outcomes. Apart from these, caffeine consumption too should be kept in check. Studies suggest that the couple’s activity levels and environmental pollutants, too, play a subtle role in IVF success. Therefore, the couple should adapt to a healthy, stress-free and active lifestyle to increase the chances of IVF success.

Sperm and Embryo Quality:

Sperm and Embryo quality plays a crucial role in the success of IVF. Without good quality sperm and embryo, conception becomes difficult even outside the human body.

Two key factors that determine sperm quality are sperm count and sperm mobility. A high sperm count increases the statistical chances of fertilization, and high mobility allows these sperm to reach the egg.

One can improve the quality of sperm by-

  • Improving the Body Mass Index (BMI)
  • Incorporating a healthy diet with plenty of fruits, vegetables and antioxidants
  • Preventing sexually transmitted infections
  • Managing stress
  • Getting more active physically.
  • Avoiding smoking and limiting alcohol
  • Avoiding lubricants during intercourse

Similarly, women, too, can work towards improving the quality of the embryo. Just like men, they should also work on improving their food habits and incorporating an active lifestyle. When ovaries get ample oxygen, the embryo quality automatically improves. Hence, women should drink plenty of fluids and oxygen-rich food while trying to conceive.

One can improve the embryo quality by-

  • Improving blood flow
  • Incorporating a healthy and oxygen-rich diet
  • Keeping stress in check
  • Avoiding smoking and alcohol
  • Managing healthy weight
Medical Guidance and Choice of Procedure:

Of course, the IVF Procedure must be done carefully and with the proper expertise. Antagonist and short protocols are the most common types of protocols used for IVF treatment. Both have roaring success rates. However, you should consult an IVF expert to understand what would be the right course of treatment for you. The medical professional will also inform you about the IVF treatment costs during consultation.

One of the most critical procedures your doctor will discuss with you, which increases the probability of success, is embryo transfer into the uterus.

Thickness of Endometrium:

The uterus has an inner lining called the endometrium. An appropriate endometrium thickness, between 7-14 mm, leads to the highest possibility of implantation.

If this ideal is not present, there are medical and lifestyle solutions, the latter being eating iron-rich foods, such as nuts, beans, and dark leafy greens.

Healthy Weight:

It is also often overlooked that maintaining a healthy weight is also helpful in making conception more likely. For both sexes, keeping weight within the optimal BMI range of 20-25 is one of the most important lifestyle factors that can affect your fertility. Excessive weight can interfere with hormones and medications.
