According to a new study from researchers at the Stanford University School of Medicine in California, obese and overweight men are more likely to have a lower sperm count, and to have lower quality sperm than average weight men.
According to a new study from researchers at the Stanford University
School of Medicine in California, obese and overweight men are
more likely to have a lower sperm count, and lower quality semen than average weight men.
The study involved 468 couples from Texas and Michigan who were intending
to conceive.
The men donated sperm and had it tested for several attributes.
They were also weighed and had their waists measured for comparison.
The results of the study show that the size of the subject’s waist,
and their body mass index were connected with the volume and
quality of semen they produced.
Subjects with waists larger than 40 inches reportedly has a 22 percent
lower sperm count than subjects whose waist size was 37 inches or
smaller.
A 2011 study on the same subject conducted in Europe with over 19
hundred subjects yielded very similar results.
A scientific director at Eylau-Unilabs in Paris is
quoted as saying: “Excess weight causes a modification in sperm
characteristics, probably as a result of hormonal disturbance, which
results in lower sperm numbers, motility and vitality.”
In the European study, sperm counts were ten percent lower in
overweight men, and 20 percent lower for men who were obese.
