Does Nutrition Affect IVF Success Rates? Expert Insights in National Nutrition Week 2025

For couples undergoing IVF, the right diet can improve egg quality, sperm health, and even increase the chances of implantation.

In this blog, we’ll explore what science says about the link between nutrition and IVF success rates, and why eating right could bring you one step closer to parenthood.

Why Nutrition Matters in IVF Success?

Nutrition plays a big role in how well IVF treatment works. The food you eat affects your body’s hormones, egg and sperm quality, and even how your uterus prepares for pregnancy. Eating the right foods gives your body the strength and balance it needs to support fertilisation and implantation.

For example, a diet rich in vitamins, minerals, proteins, and healthy fats can improve egg health, boost sperm count, and increase the chances of a healthy embryo attaching to the uterus. On the other hand, poor eating habits like too much junk food, sugar, or processed items can reduce IVF success.

According to Nutrition and Fertility, nutrition highly impact IVF by improving egg quality, sperm growth, hormone regulation and overall fertility health.

How Does Poor Nutrition Affect Fertility and IVF Outcomes?

Just like a car needs good fuel to run smoothly, your body also needs the right food to function properly. When nutrition is poor, it can create many hurdles in your fertility and IVF journey.

Weak egg and sperm health: Lack of important nutrients like protein, iron, and vitamins can reduce egg quality and sperm count.

• Hormone imbalance: Junk food, excess sugar, and unhealthy fats can disturb hormones that are needed for ovulation and sperm production.
• Poor uterine lining: Without enough nutrients, the uterus may not prepare properly to hold the embryo.
• Reduced energy and stress control: Eating unhealthy foods can make you feel tired, stressed, or anxious, which indirectly affects IVF outcomes.
• Fertility Expert Advice: Poor nutrition lowers the body’s ability to support fertilisation, implantation, and pregnancy. This is why following a healthy diet is so important during IVF.

Foods to Improve and Avoid for High IVF Success Rates

The food you eat during IVF can either boost your chances of success or reduce them. A fertility-friendly diet supports healthy eggs, sperm, and a strong uterus for implantation. On the other hand, unhealthy food can harm hormone balance and reduce IVF outcomes.

Here’s a quick look at foods to eat vs. foods to avoid during IVF:

Does a Male's Nutrition and Diet Also Affect IVF Success?

Yes, male nutrition & diet matters just as much as female nutrition when it comes to IVF success. Just like eggs need proper nutrients, sperm also need the right balance of vitamins, minerals, and antioxidants to stay healthy and strong.

Understand how male nutrition also affects IVF chances:

• Poor diet in men (junk food, alcohol, too much sugar) can lower sperm count, reduce movement, and increase DNA damage.
• A healthy diet in men (fruits, veggies, nuts, lean proteins, whole grains) improves sperm quality, which directly increases the chances of IVF success.
• Nutrients like zinc, vitamin C, vitamin E, folate, and omega-3 are especially important for sperm health.

How Weight and Nutrition Work Together in IVF?

When it comes to IVF, both weight and nutrition go hand in hand. Your body needs the right balance to prepare for pregnancy, and being either overweight or underweight can lower IVF success rates.

Here is how weight and nutrition work together in IVF:

• Overweight (high BMI):

It can lead to hormonal imbalance, poor egg quality, and lower chances of embryo implantation.

• Underweight (low BMI):

May cause irregular periods, poor ovulation, and a weaker uterine lining for embryo support.

• Right Nutrition:

Eating a balanced diet (whole grains, lean proteins, fruits, veggies, and healthy fats) helps maintain a healthy weight, improves egg and sperm quality, and supports the body during treatment.
