The findings in two new studies suggest that dietary habits of a woman are directly related to the success or failure of their infertility treatments. It has been warned that those of who are in the habit of drinking five cups of coffee a day or more are eliminating their chances of a successful in vitro fertilization (IVF) treatment.

During the course of the study, Danish researchers analyzed more than 4,000 women who underwent IVF. They subjected that those of who were heavy coffee drinkers and consumed a diet rich in fats, were stated to experience the same after effects as those produced for women, who smoke during their pregnancy.

It has been exclaimed that pregnancy rate is reduced by 50% and live birth by 40%, in case of drinking five or more cups of coffee in a day.

Dr Ulrik Schioler Kesmodel from Denmark's Aarhus University Hospital fertility clinic said “Although we were not surprised that coffee consumption appears to affect pregnancy rates in IVF, we were surprised at the magnitude of the effect”.

However, Dr. Kesmodel suggested that if coffee is taken in lower quantities during the period, then it doesn’t have any harmful effects. Moreover, he confirmed that the results obtained from the study were reasonable evidences to support the fact.
