Preparing for IVF or ICSI in Thailand involves more than medications and appointments. The food you eat before and during treatment helps support your body’s overall health, hormone balance, and reproductive function. While no single food or supplement can guarantee pregnancy, good nutrition supports a healthier environment for egg development, sperm production, embryo implantation, and pregnancy.
Many couples ask which food is good for IVF treatment, what to eat during IVF, or whether there is a special diet that improves IVF and ICSI success rates. Although there is no universal fertility diet, research consistently supports eating a balanced dietary pattern rich in vegetables, fruits, whole grains, lean proteins, healthy fats, and antioxidant-rich foods.
At Bangkok Central Clinic, we encourage patients to view nutrition as one part of a comprehensive fertility plan. Alongside advanced IVF and ICSI treatments, healthy lifestyle choices can support reproductive health before, during, and after treatment.
Why Diet Matters for IVF and ICSI Success
Nutrition affects many aspects of fertility in both women and men. While IVF and ICSI overcome many barriers to conception, treatment outcomes still depend on the health of the eggs, sperm, uterus, and developing embryos.
A nutritious diet helps support healthy egg development, sperm production and motility, hormone regulation, and endometrial (uterine lining) development. It also supports a healthy body weight and reduces oxidative stress. Because egg and sperm cells are particularly sensitive to oxidative stress, diets rich in antioxidants may help protect reproductive cells from damage.
For women, proper nutrition supports ovarian function, follicle development, and endometrial receptivity. For men, nutrition influences sperm concentration, movement, shape, and DNA integrity.
This is why fertility specialists encourage both partners to improve their eating habits several months before beginning IVF or ICSI.
Best Foods to Eat Before IVF Treatment
One of the most common questions patients ask is what food to eat before IVF. Ideally, healthy dietary changes should begin at least two to three months before treatment. This timeframe corresponds with sperm development and the later stages of egg maturation.
Rather than focusing on individual “superfoods,” aim for an overall eating pattern that includes plenty of colorful vegetables, fresh fruits, whole grains, lean proteins, and healthy fats. Adequate hydration is also important. This approach provides vitamins, minerals, antioxidants, fiber, and healthy fats that support reproductive health.
Foods for Female Fertility Support
A woman’s nutritional status influences ovulation, hormone production, egg quality, and uterine health. While nutrition cannot reverse age-related fertility decline, healthy eating supports the body’s natural reproductive processes.
Leafy Green Vegetables: Spinach, kale, bok choy, broccoli provide folate, iron, vitamin C, and magnesium. Folate supports DNA synthesis and healthy cell division, making it particularly important before conception.
Whole Grains: Brown rice, oats, quinoa, and Whole wheat bread. Whole grains provide steady energy while supplying B vitamins, fiber, and magnesium.
Healthy Fats: Avocados, olive oil, nuts, and seeds. Healthy unsaturated fats support hormone production and reduce inflammation.
Omega-3 Fatty Acids: Salmon, sardines, trout, and mackerel for hormone balance, cell membrane health, and early fetal brain development after conception.
Folate-Rich Foods: Lentils, beans, asparagus, leafy greens, and citrus fruits.
Dairy Foods: Moderate amounts of dairy products provide protein, calcium, vitamin D, and iodine.
Foods for Male Fertility Support
Male fertility contributes to approximately half of infertility cases. Improving nutrition before ICSI may support sperm production, motility, and overall sperm quality.
A healthy male fertility diet includes fruits, vegetables, whole grains, fish, legumes, nuts, seeds, and lean poultry. Lifestyle changes are equally important. Men preparing for ICSI should aim to maintain a healthy weight, stop smoking, limit alcohol, exercise regularly, get adequate sleep, and manage chronic stress.
Several studies have shown that healthier dietary patterns, particularly those similar to the Mediterranean diet, are associated with better semen quality.
Foods That Support Sperm Quality
Patients often ask whether there are specific foods that can naturally improve sperm quality. While no single food can dramatically change fertility, consistent healthy eating over several months can support normal sperm production.
Fruits and Vegetables: Aim for at least five servings daily. These foods provide antioxidants that help protect sperm cells from oxidative damage.
Fish: Oily fish supplies omega-3 fatty acids that contribute to healthy sperm membranes and motility. Choose lower-mercury varieties and consume them in moderation.
Whole Grains: Whole grains provide complex carbohydrates and micronutrients that support overall health and energy metabolism.
Legumes: Beans, lentils, and chickpeas provide plant protein, iron, zinc, and folate.
Nuts and Seeds: Walnuts, almonds, pumpkin seeds, and sunflower seeds supply healthy fats, selenium, vitamin E, and zinc.
Lean Protein: Skinless poultry, eggs, fish, tofu, and beans. Limit processed meats and excessive red meat, as diets high in processed meat have been associated with poorer semen quality in observational studies.
Good nutrition should be paired with regular physical activity, adequate sleep, and avoiding smoking or excessive alcohol consumption. Together, these lifestyle habits help create the healthiest possible environment before ICSI begins.
Foods to Avoid During IVF
Knowing the foods to avoid during IVF is just as important as knowing what to eat.
Alcohol: Alcohol has been associated with reduced fertility in both women and men. Many fertility specialists recommend avoiding alcohol entirely during IVF treatment.
Excess Caffeine: Moderate caffeine intake appears safe for most women. Current guidelines generally recommend limiting caffeine to approximately 200 mg per day, which is roughly equivalent to one regular 12-ounce cup of coffee.
High-Mercury Fish: Avoid fish known to contain higher mercury levels, including shark, swordfish, king mackerel, tilefish, marlin, and bigeye tuna. Instead, choose lower-mercury fish such as salmon, sardines, trout, cod, and tilapia.
Highly Processed Foods: Try to reduce foods high in refined sugar, saturated fats, and artificial trans fats, such as fast food, sugary beverages, packaged snacks, processed meats, and other processed foods.
Raw or Undercooked Foods: During IVF and early pregnancy, avoid raw oysters, sushi containing raw fish, and raw eggs.

Frequently Asked Questions About Foods to Eat During IVF and ICSI
Q: What is the best food to eat before and during IVF treatment?
A: There is no single “best” food. A balanced diet rich in vegetables, fruits, whole grains, lean proteins, healthy fats, and omega-3-rich fish provides nutrients that support overall reproductive health during IVF.
Q: What foods improve egg quality quickly?
A: Egg quality develops over several months, so there is no food that improves it immediately. Eating antioxidant-rich foods such as berries, leafy greens, nuts, and fatty fish, along with maintaining healthy lifestyle habits, may support egg health over time.
Q: Should men follow the IVF diet too?
A: Yes. Male fertility contributes to fertilization and embryo development. A nutritious diet rich in antioxidants, zinc, selenium, omega-3 fatty acids, and adequate protein can support normal sperm production and quality.
Q: Can I drink coffee during an IVF cycle?
A: Moderate caffeine intake, generally up to 200 mg per day, is considered acceptable for most women trying to conceive. If you have specific medical concerns, discuss caffeine intake with your fertility specialist.
Q: Is pineapple really good after embryo transfer?
A: Pineapple contains bromelain, but there is currently insufficient scientific evidence about pineapple being a food to help in IVF embryo implantation. It can be enjoyed in moderation as part of a balanced diet.
Q: How long before IVF should I change my diet?
A: Ideally, begin making healthy dietary changes 2–3 months before IVF or ICSI. This timing aligns with sperm development and the later stages of egg maturation, allowing your body time to benefit from improved nutrition.
Q: Are supplements necessary for IVF?
A: Many patients are advised to take supplements such as folic acid before and during pregnancy. Other supplements, including vitamin D, omega-3 fatty acids, iron, or CoQ10, may be recommended based on individual nutritional status, laboratory results, and medical history. Always consult your fertility specialist before starting supplements.
Q: What food should I eat after IVF transfer?
A: After embryo transfer, focus on eating a balanced diet that includes lean proteins, whole grains, fruits, vegetables, and healthy fats. Good choices include eggs, chicken, salmon, leafy greens, berries, avocados, yogurt, beans, and brown rice. Stay well hydrated and continue taking your prescribed prenatal vitamins. Although many people search for a specific food to eat after an IVF transfer or to help with implantation in IVF, there is no scientific evidence that any single food can improve implantation. Instead, maintaining a nutritious diet and following your fertility specialist’s advice provides the best support for your body during the two-week wait.
