Fertility is the ability to conceive and have a baby. It is influenced by various factors, including age, hormonal imbalances, and body weight.

While it is commonly known that being overweight or underweight can affect fertility, the precise connection between fertility and body weight is not well understood.

What is a Healthy Body Weight?

The body mass index (BMI) is a measure of body fat based on height and weight. It is used to categorize individuals as underweight, normal weight, overweight, or obese.

A BMI of 18.5 to 24.9 is considered normal, while a BMI of 25 to 29.9 is overweight, and a BMI of 30 or more is considered obese.

The Impact of Weight on Fertility

Weight impacts fertility in both men and women. Studies have shown that being overweight or obese can reduce a man’s sperm count, motility, and morphology. Obesity can also cause hormonal imbalances in men that affect fertility.

In women, being overweight or obese can cause polycystic ovary syndrome (PCOS), which is one of the leading causes of infertility. PCOS is characterized by irregular periods, hormonal imbalances, insulin resistance, and high levels of male hormones (androgens). Women with PCOS have difficulty ovulating and conceiving as a result.

Being underweight can also affect fertility. Women who are underweight (BMI less than 18.5) often have irregular periods or stop menstruating altogether.

This is because their bodies do not have enough fat to produce estrogen, which is necessary for ovulation. Underweight women may also have more difficulty conceiving because their bodies are not in an optimal state for fertility.

How Weight Affects Fertility Treatments

Weight can also impact fertility treatments, such as in vitro fertilization (IVF). Studies have shown that obese women have a lower chance of success with IVF than women of normal weight.

This may be because obese women have lower quality eggs and embryos or because their bodies do not respond as well to fertility drugs. Conversely, being underweight can also affect IVF success rates. Women who are underweight may produce fewer eggs during IVF, reducing their chances of conceiving.

What Can You Do?

If you are struggling with fertility and are overweight or underweight, making lifestyle changes to achieve a healthy body weight can help improve your chances of conceiving. Here are some tips:.

1. Eat a Balanced Diet

Eat a diet that is low in processed foods, sugars, and unhealthy fats, and rich in fruits, vegetables, and lean proteins.

A balanced diet will help you achieve a healthy body weight and provide your body with the nutrients it needs for optimal fertility.

2. Exercise Regularly

Regular exercise can help you achieve a healthy body weight, reduce stress, and improve hormonal balance. Aim for at least 30 minutes of moderate-intensity exercise, such as brisk walking, cycling, or swimming, most days of the week.

3. Get Enough Sleep

Getting adequate sleep is important for hormonal balance and fertility. Aim for 7 to 8 hours of sleep each night, and create a sleep-conducive environment by keeping your bedroom cool, dark, and quiet.

4. Manage Stress

Stress can disrupt hormonal balance and affect fertility. Find ways to manage stress, such as through meditation, yoga, or counseling.

5. See a Fertility Specialist

If you have been trying to conceive for over a year (or six months if you are over 35), and have not been successful, see a fertility specialist.

A specialist can help assess your fertility and recommend treatments to improve your chances of conceiving.

Conclusion

Being at a healthy body weight is important for overall health and fertility. Being overweight or underweight can reduce fertility in both men and women, and can affect the success of fertility treatments.

By eating a balanced diet, exercising regularly, getting enough sleep, managing stress, and seeking help from a fertility specialist if necessary, you can improve your chances of conceiving.
