Does being overweight cause Male infertility?

Being overweight can cause male infertility. In this post, I will try to answer the question “how does being overweight cause Male infertility?” For our two failed IVF treatments, I was overweight. This may have been one of the reasons for my unexplained infertility. If you are carrying an extra few pounds and plan on having a baby then you should focus on shedding that excess body weight. Unless you are one of those lucky bastards with a fast metabolism, that can eat shit until the cows come home and still remain ripped, then weight loss will take a lot of hard work. To increase the chances of you and your partner getting pregnant and having a healthy baby, you should start with a healthy diet exercise plan as soon as possible.

Being overweight causes both male and female infertility.

For women that are overweight, it can take much longer to get pregnant and there is a greater risk of complications during pregnancy. When we were going through our first two IVF treatments, I was slightly overweight and needed to shed some extra pounds. Before each IVF treatment, I started a rigorous exercise regime but it wasn’t until the third treatment that I got my diet in order that I saw serious results.

Weight loss is 80% diet and 20% exercise. Following a strict diet is considerably harder than working out. If you eat 5 meals a day and five snacks, that’s 10 times per day that you have to watch what you are eating. For a healthy exercise program, you will only have to be strict about working out once per day, 3-5 times per week. Working out is physically more demanding than your diet but it there is fewer instances per day where you have to be strict. If you are serious about having successful IVF then you have to be strict about what you eat too. It takes hard work and commitment.

How can I tell if I’m overweight or not? Does being overweight cause Male infertility?

The best way to find out if you are overweight is by calculating your body mass index(BMI). BMI is a ratio of your weight and height. Wikepdidia describes the calculation as “The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m2, resulting from mass in kilograms and height in metres.” There are many tools online for calculating BMI.

BMI and being overweight cause Male infertility. Which category of BMI do you fall into?

  1. underweight (BMI less than 18.5)
  2. average weight (BMI between 18.5 & 24.9)
  3. overweight (BMI between 25.0 & 29.9)
  4. obese (BMI 30.0 and above)

How can I lose weight?

The best way to lose weight is to follow a strict diet and regular exercise plan. It can be difficult to maintain but it’s necessary if you want to have successful IVF treatment. It is amazing what can be achieved in just 12 weeks. If you follow a strict diet and exercise plan for 3 months then you can see amazing results even if you are overweight or obese.

How does being overweight cause male infertility?

It is a fact that men who are both overweight and obese have a much lower sperm quality than men with a healthy BMI. Carrying excess weight may also cause hormonal imbalances that can potentially reduce fertility and sex drive. It is also common for men that are overweight to suffer from erectile dysfunction. A combination of these factors greatly reduce the chances of overweight men fathering a child.

Further Reading:

A veteran of 3 ICSI treatments, I have learnt a lot on my journey. For our third and final IVF treatment, many changes were made to my lifestyle. I got fit and healthy and my weight went from 96 to 88 kilos in three months. After all of the changes, the IVF treatment worked.  I’m not sure if weight loss was the reason that last IVF treatment was a success. It was one of the factors that could have been hindering us so I made a big effort and lost a lot of weight. If you are serious about having a successful fertility treatment then losing weight may be one of the changes that you will have to make if you want to have a family.
