During the process of preparing for pregnancy, many people think that it is mainly the responsibility of women, but in fact, having a healthy baby requires the joint efforts of both partners. Mr. Wang's case vividly reveals this point. Mr. Wang, 31 years old, is 170 cm tall and weighs over 240 pounds. After six years of marriage, he has not been able to have children. After examination, it was found that the problem was with Mr. Wang, specifically manifested as short reproductive organs and poor sperm quality, which were closely related to his obesity.

 

Obesity has many adverse effects on the human body, some of which also affect fertility. First, obesity affects heart function and the cardiovascular system. Obese people’s blood pressure circulation and metabolism are affected, blood stasis and poor vascular circulation lead to problems with vascular elasticity and hardness, increasing the heart’s burden and further affecting its normal function.

 

An increasing number of studies indicate that male obesity not only affects fertility, but also has adverse effects on offspring. Obesity can affect the genetic information in male sperm, transmitting dietary information to offspring. Obesity has a certain degree of heritability, and male obesity during preconception can increase the risk of cancer in offspring.

 

Specifically, regarding fertility, obese men often have insufficient androgen levels, leading to short penises, affecting sexual life, and thus affecting fertility. Excess fat accumulation around the scrotum can compress the spermatic blood vessels, causing testicular ischemia and affecting sperm production. Leptin secreted by adipose tissue also negatively affects sperm production. Additionally, the high-temperature environment in the scrotum is not conducive to sperm generation, leading to a decrease in sperm count and an increase in dead sperm.

 

Mr. Wang was troubled by infertility caused by obesity, and he began to consider achieving his fertility dream through IVF. However, studies have found that male obesity adversely affects the success rate of IVF. A study published in the British journal "Scientific Reports" under "Nature" Weekly showed that overweight or obese men affect the effectiveness of IVF treatment. The study found that a high body mass index (BMI) in men leads to shortened sperm telomere length, decreased mitochondrial activity, and increased sperm DNA fragmentation rate, ultimately affecting embryo quality and pregnancy rates.

Controlling weight within a reasonable range not only helps with natural pregnancy but also improves the success rate of IVF.
