Obesity & Fertility

Will My Weight Affect My Chances Of Conceiving?

Finding ways to boost infertility is not a big puzzle, it certainly can be achieved without any professional supervision. You need to only follow a healthy routine, maintain certain body weight, and keep a track record of your ovulation peak. It may be harder to conceive if you’re significantly overweight or underweight because both conditions can interfere with normal ovulation or the monthly release of an egg from one of your ovaries.

Studies have shown that people who are overweight have more difficulty with conception. Shedding even a few pounds would do the trick. Obesity in males, makes the levels of testosterone go up, which in turn causes low sperm motility.

In our body, the expenditure of energy and the intake of food is controlled by a protein called leptin, which is produced by the fatty tissue. It is also responsible for regulating reproductive function in our body. When the intake of food exceeds the energy expenditure, body weight increases, leading to obesity and hence, infertility.


Know Your BMI:

Body Mass Index (BMI) is an indication of your body weight and can be calculated by dividing weight by height. You should aim for a BMI of between 22 and 24.9, as this will optimize your chances of conception. If a woman’s BMI falls below 19(Underweight), the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. If your BMI is between 25 and 29.9, then you are considered overweight and if your BMI is over 30 then it is termed as Obese. Adults with a BMI greater than or equal to 40 are considered extremely obese. When a person has accumulated so much body fat that it starts having an adverse effect on their health, this condition is called obesity.

Obesity can happen for many different reasons. From the intake of too many calories, sedentary lifestyle, obesity causing genes and even medications that cause weight gain, obesity can almost happen because of anything.



Whatever the case may be, obesity can hamper fertility in men as well as women. Many don’t know but obesity is directly connected to infertility and reproductive functions. Other than hurting your chances of becoming pregnant excess weight can have the following adverse effects on your body:


  1. Hormonal Imbalance

Once the BMI is more than thirty, many hormonal changes occur in the body. These hormonal changes, decrease the chances of conceiving a child. Women, who are overweight have fewer chances of conceiving than women who are not. They are likely to take a year more than healthy women to be able to conceive. Even if she conceives, the chances of pre-eclampsia almost double sometimes triple up. They carry twice the risk of developing gestational diabetes in comparison to healthy women. The chances of miscarriage are also twice, in comparison to other women.

2. Insulin Resistance

Obesity is likely to cause insulin resistance, which technically elevates the chances of developing type 2 diabetes, or diabetes mellitus. Moreover, insulin resistance or IR can also affect your fertility and menstrual cycles. It leads to anovulation, a condition in which ovaries do not produce eggs properly.


How Underweight Affects Fertility:

People who are underweight aren’t far from same, either. Body strength is as tied up to carry out pregnancy as healthy fertility. Research has shown that, on average, women who are underweight take longer to conceive than those who are a healthy weight. You’re more likely to have an irregular menstrual cycle if you’re underweight, which means that you may not release an egg (ovulate) during each cycle. This makes it more difficult to conceive. Fortunately, getting to a healthy weight should improve your chances.

Being over and underweight can lead to infertility and the fertility treatments might also not work. Regularly exercising will boost your fertility fivefold, and keep you healthy at best. Adopting a healthy lifestyle gives you increased fertility that subsequently leads to a healthy baby. So, eat healthily and exercise regularly.
