Compared with men of normal weight, overweight and obese men were more likely to have low sperm count, or not have any viable sperm, researchers in France found.
"These data strongly suggest that excess body weight affects sperm production," the researchers wrote in their conclusion.
They found that among men who were normal weight, 24 percent had a low sperm count and 2.6 percent had no viable sperm. Among the overweight men, 25.6 percent had a low sperm count and 4.7 percent had no viable sperm. Of the men who were obese, 32.4 percent had a low sperm count and 6.9 percent had no viable sperm.

TODAY'S BOOK SUGGESTION:
Test tubes and testosterone (Male Infertility)
-- What do you need to make a baby? A willing partner? A good sense of timing? Some wine maybe? A nice meal and some amorous music? Not always. There are times when all the romance (and luck) just simply will not do. In those times, what you need is a specimen pot, a heap of drugs, so many ultra-sound scans that your wife or partner begins to glow in the dark and an unfeasibly large amount of tea.
Providing a rare yet enlightening male perspective on the world of IVF, 'Test tubes and testosterone' is one man's experience of infertility and the IVF journey he embarked on with his wife in order to start a family. Told with humour, wit and insight, this book sheds light on issues that can be hard to discuss even with the closest of friends or relatives, making it a valuable book for anyone contemplating or going through IVF.
