Murray Koffler Urologic of urological Wellness Centre and Head of Urology at Mount Sinai Hospital, Toronto, Keith Jarvi, say, the heavier man, the more likely they are a little sperm. " Unfortunately, not many men are aware of it, " he said.
Is Michael Eisenberg of Stanford University School of Medicine in California, whose team conducted an analysis of 468 couples in Texas and Michigan who were in the program of pregnancy. The researchers conducted several measurements of sperm in the semen of the husband. In addition, they also measured the body mass index ( BMI ) of participants.
As a result, the more obese a man, the less they spend sperm volume during ejaculation. " Every aspect of semen quality is very important. Moment of ejaculation, some compounds also issued to provide safe conditions for sperm. If the number of sperm released a little, this will certainly be an issue, " said Eisenberg.
Total sperm count sperm is released in each cc of cement. Jarvi said, the more volume of cement is issued, an average of 2-5 milliliters usually have more sperm. Meanwhile, if the cement is issued under 1.5 milliliters increased risk of infertility.
" But if the volume is too much is also not good, " he said.
In this study, men with a normal BMI sperm with an average volume of 3.3 milliliter of ejaculate. While in men with high BMI or obesity category average of 2.8 milliliters issued.
However, a study published in the journal Human Reproduction that does not state there is no difference between motility, vitality, and physical appearance of sperm among people with normal BMI with obesity.
