Introduction
In today's blog post, we will explore the fascinating relationship between weight and fertility in men. Understanding this connection is crucial for those who are planning to start a family, as it sheds light on the potential impact of Body Mass Index (BMI) on male fertility. We will be sharing key insights from a groundbreaking research paper by Shayeb et al. (2011) that delves into this topic. By the end of this post, you will have a better understanding of the importance of maintaining a healthy weight range and how it can potentially affect your journey to fatherhood.
What is BMI?
Body Mass Index (BMI) is a numerical value calculated from a person's weight and height. It is commonly used as an indicator of whether an individual has a healthy body weight in relation to their height. BMI provides a general assessment of body fat and is widely used in medical and health fields to evaluate the risk of certain health conditions associated with weight, such as obesity and related diseases. It is important to note that while BMI is a useful tool for population-level assessments, it does not take into account other factors such as muscle mass or distribution of body fat.
What is the Impact of BMI on Male Fertility?
The research reveals that obese men are more likely to have a low semen volume and fewer spermatozoa with normal morphological characteristics when compared to men within a healthy weight range. In simple terms, as BMI increases, the quality and quantity of a man’s sperm may decrease. This begs for urgent attention, especially since the global trends reveal an escalation in obesity cases.
There are a couple of mechanisms that explain the effect of body weight on male fertility. The first mechanism has to do with hormones. Increased weight is usually associated with lower levels of testosterone and higher levels of estrogen. The regulation of these hormones is critical for sperm production. Secondly, obese men are more likely to have cardiovascular diseases and type 2 diabetes. This is associated with erectile dysfunction. Third, the temperature of the scrotum needs to be a couple of degrees lower than body temperature. Excess fat between the thighs can lead to increased scrotal temperature (Khan, 2017).
