Bodyweight can often be a delicate topic, but it is necessary to address it, as it can have a huge effect on a person’s overall health as well as the capability to reproduce. The BMI which is known as the Body Mass Index is the key index relating weight to height and represents an accurate measurement which permits physicians to know if someone is overweight, underweight, extremely obese or obese. When overweight, your health can be affected adversely as conditions like heart disease, diabetes and hypertension among others are much more common.
Just like women who develop fertility issues related to BMI, men also experience the same problems. If men are overweight, it can affect the sperm motility (how the sperm cells move) and sperm count. When the male hormone production is disturbed because of the increased body mass index, it may affect the man’s capability to produce healthy sperm on a regular basis. Also, the natural balance of estrogen and testosterone could be impaired, which may, in the end, affect the whole process of sperm production (spermatogenesis). Men who are obese also suffer from excess warming of the scrotum. If the temperature of the scrotum increases just by 1 or 2%, it can impair the production of sperm or sperm survival. Maintaining a healthy BMI leads in various ways towards proper spermatogenesis. Men normally produce millions of fresh sperm cells on a daily basis, so striving towards a healthy lifestyle is of huge importance. Sperm cells take about 74 days to mature in the male body which means that those who make positive lifestyle changes or those who lose weight might need to wait up to 3 months before sperm production and quality is improved.
There may be several ways in which excess body fat affects male fertility, and in many cases, many factors contribute at the same time towards defective spermatogenesis. Some common problems include:
Although erectile dysfunction represents a complicated condition, obesity affects negatively self-esteem which can be a major problem in many otherwise healthy individuals, leading to erectile problems. Additionally, many obese people develop conditions like diabetes or hypertension which impair the blood flow towards the penis leading to problems achieving a satisfactory erection.
