Lifestyle affects fertility: Fertility isn’t just about age or genetics. While those certainly play a role, your daily lifestyle choices have a significant impact on your ability to conceive, whether you’re a man or a woman.
From what you eat to how much you sleep, your body is constantly responding to your environment. And when it comes to reproductive health, even small changes in habits can make a big difference.
Let’s explore how lifestyle factors influence fertility, and what you can do to support your journey to parenthood.

Stress: The Invisible Fertility Blocker
Modern life is full of deadlines, screens, and sleep deprivation, and chronic stress can quietly disrupt reproductive function.
In women, stress may interfere with ovulation, delay periods, or worsen conditions like PCOS.
In men, prolonged stress can reduce testosterone levels and sperm count.
Tip: Prioritise relaxation, whether through yoga, meditation, journaling, or simply stepping away from work when needed.
Diet: What You Eat Affects Your Eggs and Sperm
A nutrient-poor diet loaded with processed foods, sugars, and trans fats can lead to hormonal imbalances, insulin resistance, and inflammation, all of which negatively affect fertility.
Women benefit from a Mediterranean-style diet rich in whole grains, healthy fats, fruits, and leafy greens.
Men need zinc, selenium, and antioxidants to improve sperm quality and motility.
Tip: Add nuts, seeds, avocados, lean protein, and colourful vegetables to your meals. Avoid excessive caffeine, alcohol, and sugary drinks.
Smoking & Alcohol: Major Fertility Disruptors
In men, smoking reduces sperm count and damages DNA in the sperm.
In women, it accelerates ovarian ageing and lowers the chances of implantation.
Excessive alcohol impacts hormone levels, ovulation, and libido in both genders.
Tip: If you’re planning a pregnancy, quit smoking completely and limit alcohol to occasional, moderate use.
Sleep: The Forgotten Fertility Pillar
Poor or irregular sleep disturbs hormonal cycles like melatonin and cortisol, which in turn can affect estrogen, testosterone, and ovulation.
Aim for 7–9 hours of restful sleep every night.
Tip: Set a regular sleep schedule, reduce screen time before bed, and avoid heavy meals or caffeine at night.
Weight Matters, For Both Partners
Women with underweight or overweight BMI may face ovulatory issues and irregular cycles.
Men with obesity often experience lower testosterone and decreased sperm quality.
Tip: Achieving and maintaining a healthy weight through a balanced diet and exercise can significantly boost natural fertility.
Environmental Exposures: Toxins That Harm Reproductive Health
Exposure to certain chemicals, like BPA, pesticides, and heavy metals, can interfere with hormones and sperm quality.
Tip: Choose glass over plastic, wash fruits and vegetables thoroughly, and avoid exposure to industrial chemicals when possible.
