London, July 8 : Women with fertility problems should stay away from guzzling too much coffee, for a new study has found that the drink can worsen the chances of women with poor fertility becoming pregnant.
Dutch researchers conducting the study followed 9,000 women who had received IVF in the Netherlands between 1985 and 1995 to see if they would conceive naturally.
The boffins from Radboud University in Nijmegan found that women who had more than four cups of coffee a day cut their chances of getting pregnant by 26 percent.
The women were asked to fill questionnaires, based on which the researchers analysed how lifestyle factors their chances of pregnancy.
It was found that excessive caffeine intake had the same risk as drinking alcohol at least three times a week.
A further noting was that smoking more than one cigarette a day and being overweight reduced the chances of pregnancy even more.
Lead researchers Dr Bea Linsten, present the study at the European Society for Human Reproduction and Embryology conference in Barcelona recently, reports the BBC.
She said: "We have to remind our patients that they may influence their chance of spontaneous pregnancy after IVF with a healthy lifestyle."
