It’s often said that size doesn’t matter. One study challenges this adage, as a smaller than normal penis can be a cause of infertility, according to recent research.
What is the normal size of a penis? If there is no rule, it seems that the smaller the penis, the greater the risk of infertility in men. This is the result of a study conducted by researchers at the University of Utah, and presented at the American Society for Reproductive Medicine conference. The survey included 815 participants who were followed for erectile dysfunction and difficulty in having children.
The difference in size is small, as researchers say that men with an average penis size of 5.28 inches are less likely to have fertility problems than those with an erect penis size of 4.9 inches or less.
“An inch may not be a striking difference, but the statistics are clear,” admits Dr. Austen Slade, who conducted the research. The relationship between penis size and infertility may be due to genetic factors, according to the doctor. For now, there is no need to worry because more studies need to be done to confirm these results. The next step is to define a minimum size limit that can predict fertility problems.
Other Infertility Factors
Men are having more and more trouble having children. In fact, infertility has increased 700% in the last 17 years. And it’s not just the size that counts. There are other factors, and other studies have shown it. Lifestyle is important, like smoking or a diet that’s too fat and too sweet. Also endocrine disrupters in the environment are believed to reduce the quality of spermatozoa. For example, sperm concentration decreased 32.2 percent between 1989 and 2005 in men aged 35. Some scientists believe that if this decline continues, the human species could be at risk.
