Size matters ..if you want to conceive

Their penises are around a third of an inch shorter when erect, on average, than those of men without fertility issues, according to analysis of sexual health clinic data.

Fertile men had an average length of 5.27in, with the infertile at 4.92in.

Study leader Dr Austen Slade of the University of Utah, Salt Lake City, said: “It may not be a striking difference but there was a clear statistical significance.

“It remains to be determined if there are different penile length cut-offs that would predict more severe infertility.” He said a shorter penis could indicate factors linked to fertility. But he added: “For now, men with shorter penises don’t need to worry about fertility.”

The study of 815 men going to a clinic over three years was presented at the world’s biggest fertility conference in Denver, Colorado, US.

But Prof Sheena Lewis of Queen’s University in Belfast said: “One thing that scares men is that size matters. To now say they have a smaller chance of becoming a father is not a good message.”
