Men who drank two or more cups of strong coffee a day had just a one in five chance of becoming fathers through IVF. However, for those who drank less than a cup, the chance of having a child rose to nearly 52 per cent. The researchers at Massachusetts General Hospital, Boston, believe that caffeine may harm sperm at a molecular level.
In the UK we drink approximately 55 million cups of coffee per day, according to the British Coffee Association. Recent research suggests it can also help you live longer. The findings, published in the Nutrition Journal, reveal that daily caffeine intake it ok - up until a certain point.
By Shaoni Bhattacharya, San Antonio. Coffee makes sperm go faster, reveals a new study by Brazilian scientists. They suggest caffeine could form the basis of infertility treatment for some men.
Does caffeine make it harder for women to get pregnant as well as lower sperm count in men? A study conducted at The University of Nevada School of Medicine in Reno showed that caffeine interfered with the muscular contractions of the fallopian tubes. The fallopian tubes are responsible for moving the egg from the ovary to the uterus. It is in the fallopian tubes where conception takes place.

And that goes equally for men or women. When either men or women drank three or more cups a day of caffeinated drinks before pregnancy — sodas, energy drinks or coffee — the woman was nearly twice as likely to lose that pregnancy early on. And if women consumed more caffeine after they conceived, they were also more likely to miscarry.
Data sharing not applicable to this article as no datasets were generated or analysed during the current study. Semen quality, a predictor of male fertility, has been suggested declining worldwide. All pertinent reports were retrieved and the relative reference lists were systematically searched in order to identify any potential additional studies that could be included.
Drinking just three cups of coffee a day decreases men's ability to father normal children, new research suggests. The research is the latest of a series of studies showing how modern life cuts both the quantity and quality of sperm. One, by the US Government, shows that men now produce only about a third as much sperm as hamsters.
Coffee may not simply wake up the brain cells - it could also boost male fertility, new research suggests. Scientists have found that men who drink coffee have sperm that moves better than the sperm of those who lay off the caffeine. The study suggests that new coffee-based treatments should be developed for men with poor sperm movement - a defect that can cause fertility problems.
Men could help their chances of becoming fathers by drinking just two cups of coffee a day, a study suggests. Researchers looking at couples trying for a baby found the right level of caffeine intake in men in the week before a couple had sex appeared to double the chance of pregnancy. These results highlight the importance of lifestyle factors during sensitive windows of reproduction.
