How long before IVF should I start lifestyle changes?

Ideally three months before, since eggs and sperm take about that long to mature. Starting later still helps.

Which foods improve IVF success?

No single food does. Pulses, vegetables, fruit, whole grains, nuts, and dairy, with fewer processed foods, are linked to better outcomes.

Is bed rest needed after embryo transfer?

No. Studies show prolonged bed rest does not improve success. Normal light activity is usually allowed, but follow your clinic's instructions.

Can Lifestyle Changes Improve IVF Success Rates?

Yes, lifestyle changes can improve IVF success rates, but only to a degree. Age, ovarian reserve, embryo quality, sperm health, and the cause of infertility matter more. Still, a healthy weight, quitting tobacco and alcohol, balanced nutrition, and regular sleep are linked to better egg and sperm quality, better embryo implantation, and more live births. Both partners should start these changes about three months before the cycle, as eggs and sperm take roughly that long to mature.

Weight and IVF Success: Does BMI Matter?

Weight can influence reproductive health and IVF treatment. Obesity in women has been associated with ovulatory problems, altered ovarian response, and lower IVF birth rates. It can also increase pregnancy-related risks.

A study linked both obesity and being underweight to lower pregnancy and live birth rates. A healthy BMI is 18.5 to 22.9, and 23 or above is overweight. Losing 5 to 10% of body weight can improve ovulation and hormone balance, especially in women with PCOS. Avoid crash diets during treatment, as they can disturb hormone levels.

Does Diet Affect IVF Success?

A balanced diet can help support general health before IVF. Include a variety of vegetables, fruits, whole grains, pulses, nuts, seeds, dairy or suitable alternatives, and protein sources such as eggs, fish, poultry or legumes.

Observational studies link a Mediterranean-style pattern to better IVF outcomes. An Indian version includes:

Dal, rajma, chana and other pulses
Seasonal vegetables and fruits
Whole-grain chapati, millets and brown rice
Curd, nuts, seeds and fish (if non-vegetarian)

Other points to note:

Folic acid: Take at least 400 mcg daily, starting a month or more before treatment. Your doctor may advise a higher dose.
Vitamin D and B12: Deficiency is common in India, and B12 deficiency is more likely in vegetarians. Get tested and supplement only as advised.
Limit: Fried snacks, packaged foods, sweets, and sugary drinks.
Caffeine: Keep it under 200 mg a day, about two cups of coffee or three to four cups of tea.

Healthy choices can support health, but they can't promise IVF success. Keeping a healthy weight, eating well, being active, sleeping well, not smoking, and limiting drinks can support your body and health.Dr Sushma K, Consultant, Obs & Gyn, Apollo Hospitals

Smoking, Alcohol, and Tobacco Chewing: IVF Success

Smoking lowers IVF success, raises miscarriage risk, and may mean more cycles are needed. This applies to cigarettes, bidis, and hookah.

Research reviewed by the American Society for Reproductive Medicine has linked smoking with reduced fertility and poorer outcomes with assisted reproductive technology. Smokeless tobacco such as gutka and khaini is linked to poorer semen quality. Avoid second-hand smoke too.

Heavy drinking is associated with lower success rates. Most fertility clinics advise both partners to avoid alcohol during treatment.

Exercise, Sleep and IVF Success

Moderate activity, such as brisk walking, yoga, or cycling for about 150 minutes a week, helps control weight and blood sugar. During ovarian stimulation, however, the ovaries enlarge; fertility specialists may advise reducing high-impact or strenuous exercise because of the risk of ovarian complications.

Aim for 7 to 9 hours of sleep. Irregular sleep and night shifts are linked to hormonal disruption and lower outcomes in a study.

Stress and IVF Failure: Does It Matter?

Research is mixed, and there is no proof that stress alone causes IVF failure. Stress can, however, disrupt sleep, eating, and exercise routines.

Yoga, meditation, and counselling improve coping and emotional wellbeing during treatment, though they have not been shown to raise pregnancy rates on their own.

Male Partner Lifestyle: Sperm Quality and IVF

A male factor contributes to roughly half of infertility cases. Sperm take about 74 days to develop; changes made for three months before egg retrieval matter. Men should:

Quit smoking, tobacco chewing and alcohol
Maintain a healthy weight
Avoid prolonged heat exposure, such as hot baths, saunas and a laptop on the lap
Take antioxidant supplements only if prescribed

Lifestyle changes cannot replace medical treatment, but when both partners start them about three months before IVF and follow the guidance, they can support egg and sperm quality and improve the chances of success.
