How lifestyle choices of both partners impact ICSI success rates?
When is ICSI needed?
- Male factor infertility – ICSI is recommended when sperm count, movement, or shape is significantly abnormal. Injecting a single healthy sperm directly into the egg helps overcome fertilisation barriers.
- High sperm DNA fragmentation – Even with normal semen reports, DNA damage in sperm can affect embryo development. ICSI helps improve fertilisation chances in such cases.
- Previous IVF fertilisation failure – Couples who have had low or no fertilisation in earlier IVF cycles may benefit from ICSI to bypass hidden fertilisation issues.
- Use of surgically retrieved sperm – When sperm is obtained through procedures like TESA or micro-TESE, numbers and motility are limited. ICSI is essential to achieve fertilisation.
- Unexplained infertility – When routine tests show no clear cause but pregnancy does not occur, ICSI may be used to maximise fertilisation potential.
- Advanced maternal age or poor egg quality – As egg quality declines, natural sperm penetration can become difficult. ICSI helps ensure fertilisation in such situations.
- Use of frozen eggs or sperm – Freezing can reduce fertilisation ability. ICSI improves the chances of successful fertilisation with frozen samples.
ICSI (Intracytoplasmic Sperm Injection) offers hope for many couples struggling with infertility. At Bavishi Fertility Institute, we believe that while it’s a powerful medical procedure, success isn’t determined solely by lab techniques — the everyday choices both partners make before and during treatment also play a vital role. Here’s how lifestyle can influence ICSI outcomes, and what couples can do to give themselves the best chance.
1. Diet & Nutrition — Building the foundation for healthy eggs and Sperm
- A balanced, nutrient-rich diet supports overall reproductive health. Adequate intake of vitamins, minerals, antioxidants and healthy fats helps maintain hormone balance, supports egg quality in women, and improves sperm health in men.
- Conversely, diets high in processed foods, refined sugar, excessive caffeine or unhealthy fats may lead to oxidative stress and inflammation — factors that can impair gamete quality and embryo development.
- Poor maternal nutrition and lifestyle choices, such as high consumption of sugar, artificial sweeteners, and soft drinks, have been shown to negatively impact oocyte quality and ICSI outcomes.

Takeaway: Both partners should aim for a wholesome, balanced diet well before starting ICSI treatment — plenty of fresh produce, lean proteins, whole grains, healthy fats and antioxidants, while avoiding excessive processed foods, sugar, soft drinks or junk foods.
2. Smoking — A significant risk to success
- Male smoking has been repeatedly linked with poorer ICSI outcomes: one study found clinical pregnancy rates of 22% when the male partner smoked versus 38% when he didn’t.
- Smoking affects semen quality, sperm motility and increases DNA damage in sperm, which may impair fertilization and embryo development.
- Though data are more limited for female smoking in ICSI cycles, smoking (active or passive) remains a known disruptor of ovarian reserve, egg quality and overall reproductive health.
Takeaway: Both partners — especially men — should strongly consider quitting smoking well in advance of ICSI treatment. Minimizing exposure to second-hand smoke is equally important.
3. Stress & Psychological well-being — The mind–body connection
- Undergoing fertility treatment can itself be stressful. Studies suggest that high levels of perceived stress in either or both partners may negatively influence ICSI outcomes.
- Psychological stress might alter hormonal balance or immune responses, potentially affecting embryo implantation or early development.
- On the other hand, couples who manage stress and support each other emotionally — e.g., through counselling, mindfulness, adequate rest — may improve their chances.
Takeaway: Managing stress is not optional — it’s part of fertility care. Couples preparing for ICSI would benefit from relaxation techniques, good communication, emotional support, and healthy lifestyle routines that support mental well-being.
4. Exercise & Body weight — Striking a balance
- Regular, moderate exercise supports general health, helps maintain optimal body weight and positive hormonal balance, all of which can benefit fertility.
- However — extremes (being underweight or overweight/obese) can have adverse effects. For instance, unhealthy body weight may disrupt ovulation in women, sperm quality in men, or alter hormone levels.
- Also, overly intense or extreme exercise regimes (especially for women) might disrupt menstrual cycles or ovulation — so moderation is key.
Takeaway: Engage in regular, moderate exercise (like walking, yoga, swimming) rather than extreme workouts, and aim to maintain a healthy weight before and during ICSI treatment.
5. Why it matters for couples — Shared responsibility, Shared outcomes
- Fertility is a shared journey. While much focus is often on the woman undergoing ICSI, evidence shows both partners’ habits matter. For instance, male smoking affects ICSI success rates irrespective of female smoking status.
- Pre-treatment lifestyle optimization — diet, quitting smoking, stress management, healthy weight — can improve egg and sperm quality, embryo development, implantation rates, and ultimately the chances of clinical pregnancy and live birth.
- The concept is simple: medical technology (like ICSI) gives couples a path — but lifestyle choices help pave that path.
Practical advice for couples at Bavishi Fertility Institute
- Start early: Begin healthy habits (balanced diet, no smoking, moderate exercise) as soon as you consider fertility treatment — at least a few months before stimulation.
- Make it a shared commitment: Both partners should adopt the changes. Fertility is a team effort.
- Seek support for stress: Consider counselling, stress-reduction techniques (yoga, meditation), adequate sleep — especially during treatment.
- Focus on moderation, not extremes: Balanced diet, moderate exercise, no unhealthy habits. Avoid crash diets, overly strenuous workouts, smoking, junk food, excessive soft drinks or caffeine.
- Communicate with your fertility specialist: Every couple’s health profile is different; your doctor at Bavishi Fertility Institute can guide you on personalized lifestyle recommendations along with medical treatment.
Conclusion
At Bavishi Fertility Institute, we believe ICSI outcomes are shaped not only by advanced medical protocols, but also by the lifestyle you and your partner lead. By adopting healthy habits, good nutrition, regular moderate exercise, quitting smoking, maintaining mental well-being you can significantly improve the chances of success. Think of ICSI as a journey and healthy lifestyle choices as the roadmap that helps you reach the destination.

Healthy Lifestyle Habits for Better IVF Outcomes
Most specialists recommend adopting healthy habits at least 3–6 months before starting ICSI, as both eggs and sperm take time to develop and respond to lifestyle improvements.
Yes. Even moderate alcohol intake may impact hormone regulation, egg maturation, sperm motility, and DNA integrity. Reducing or avoiding alcohol prior to ICSI can support better success rates.
Poor sleep affects stress hormones, metabolism, and reproductive hormone balance. Good-quality sleep (7–8 hours) supports healthier eggs and sperm.
Certain supplements like folic acid, Vitamin D, CoQ10, omega-3, and antioxidants may support gamete quality — but they should only be taken under medical guidance.
Frequent exposure to pesticides, plastics (BPA), industrial chemicals, excessive heat (saunas, hot tubs), or radiation can reduce sperm count and may affect egg health. Reducing these exposures helps optimize reproductive outcomes.
Prolonged heat exposure from laptops on the lap or carrying phones in front pockets may affect sperm motility. Men are advised to avoid direct heat near the groin.
Yes. Conditions like diabetes, thyroid imbalance, hypertension, or PCOS can impact reproductive health. Managing these conditions effectively improves the chances of success.
