Nowadays we\u2019ve all heard of BMI: the calculation based on weight and height that gives you a BMI \u2018score\u2019. Many of us probably have a rough idea of our own BMI and know whether we come somewhere in the range of normal. We mostly use this number to calculate if we are over or under the ideal weight for our height. It is therefore associated with weight management. But there is also a great deal of evidence that BMI and infertility<\/strong> are directly linked in a way that may come as a surprise to some.<\/p>\n In this IVI blog article, we look how BMI and infertility<\/strong> are connected. We show you how to calculate your BMI. We also explain the various ways in which being over or under a normal weight can not only have an impact on your fertility but, if you do become pregnant, can cause problems for you and your unborn baby.<\/p>\n Body Mass Index (BMI)<\/a> is a measure calculated by dividing your weight in kilograms by your height in metres squared. So if you weigh 65 kilos and are 1.7 metres tall, the sum would be 65 \/ (1.7 x 1.7), with the result being a BMI of 22.5, which is a healthy weight. You don\u2019t need to get the calculator out, as you can find plenty of online apps that will do the sum for you. Just search for BMI calculator. Here\u2019s what the results generally mean:<\/p>\n The relationship between BMI and fertility is not always straightforward. Generally, having a high amount of body fat can cause disruption to the normal hormone balance. However, in some cases an underlying imbalance can cause weight gain in the first place. This is why, if an eventual link between your weight and infertility <\/strong>concern you, it\u2019s sensible to see a doctor. Being overweight can cause fertility problems in several ways:<\/p>\n According to the European Journal of Public Health, there are significantly more overweight people, at 53% of the population, than underweight, at only 2%. While this illustrates the difference in the scale of the problem, there are still many individuals whose fertility is compromised by being underweight, that is with a BMI of less than 18.5.<\/p>\n For men who are overweight, there could be a link to changes in the balance of hormones, particularly testosterone, which are crucial for reproduction. An imbalance can result in a low sperm count and low sperm motility. A study published in the Harvard School of Public Health found that obese men had a 42% higher chance of a low sperm count than normal-weight men, and were 81% more likely to produce no sperm at all. However, it is not completely clear at this stage if the low sperm count was directly caused by obesity or by other underlying health issues.<\/p>\n Having a BMI that is too high not only compromises your likelihood of becoming pregnant. It also brings a higher likelihood of risks to a healthy pregnancy for you and your baby. These risks include:<\/p>\n We should emphasise that these are risks, not inevitabilities. It is perfectly possible to have a healthy pregnancy if you have a high BMI. It’s true that the progress of your pregnancy will need to be closely monitored over a course of antenatal sessions.<\/p>\n We know that there is no magic wand for people who are overweight and who may have been struggling to manage the situation for many years. However, the good news is that if you can manage to bring your BMI down by just a few points, it will have a big impact on your pregnancy prospects. The first step is to contact your healthcare professional to discuss a plan based around a healthy balanced diet<\/a> and an appropriate level of exercise.<\/p>\n If you are concerned about BMI and infertility<\/strong>, it\u2019s quite possible that there are other conditions underlying your weight gain and preventing you from getting pregnant. For example, polycystic ovarian syndrome (PCOS) have often to do with weight gain and could well be the cause of your infertility rather than the weight itself. At IVI we have a wealth of experience in treating PCOS with IVF<\/a> and other treatments to resolve fertility problems.
