One way to increase your fertility is to bring your weight to a healthier level. Being over or underweight can upset hormone balance, leading to lower sperm counts.
Not sure if your weight is within the healthy zone? Check your body mass index (BMI). Your BMI is a measurement of your weight that also takes into account your height.
In a study on thin men, they found that men with a BMI less than 20 had lower sperm concentration and a 28.1% lower total sperm count. They also found that FSH, a hormone that plays a role in the reproductive system, was higher in slim men.
In a separate study, men with obesity had lower testosterone levels. Also, as BMI levels went up, the incidence of lower sperm counts went up. For example, for men with a normal BMI, 5.32% were found to have low sperm count. In overweight men, 9.52% had low sperm counts, and in obese men, 15.62% had low sperm counts.
