Being overweight, particularly obesity when trying to conceive can have a negative impact on male fertility. Several studies have shown that obese men have a higher risk of infertility than men of healthy weight. Here are some of the ways in which obesity can affect male fertility:
-
Hormonal imbalances: Obesity can lead to hormonal imbalances, such as decreased testosterone levels and increased estrogen levels, which can affect sperm production and quality.
-
Sperm quality: Obese men may have lower sperm quality, such as reduced motility (ability to swim), decreased count, and abnormal morphology (shape and size). These factors can make it difficult for sperm to fertilise an egg.
-
Erectile dysfunction: Obese men may also have a higher risk of erectile dysfunction, which can make it difficult to achieve or maintain an erection for sexual intercourse.
-
Increased oxidative stress: Obesity can cause increased oxidative stress in the body, which can damage sperm cells and reduce fertility.
-
Inflammation: Obesity can also cause chronic inflammation, which can affect sperm quality and production.
-
Poor lifestyle habits: Obesity is often associated with poor lifestyle habits, such as a sedentary lifestyle and unhealthy eating habits, which can further contribute to poor sperm quality and fertility.
Therefore, it is important for obese men who are trying to conceive to make lifestyle changes, such as losing weight, improving their diet, and increasing physical activity to help improve their fertility. Seeking medical advice and treatment options may also be helpful for those struggling with male infertility.
