Food therapy: Intake of Coffee Caffeine > 300mg/day Increased Risk of Delay Conception

By Kyle J. Norton


In compared to herbal medicine, food therapy even takes longer to ease symptoms, depending to stage of the treatment which directly addresses to the cause of disease.

Caffeine found in coffee consumption may increase risk of delayed conception depending to amount of caffeine intake per day, a renowned European institute study suggested.

Infertility is defined as inability of a couple to conceive after 12 months of unprotected sexual intercourse or can not carry the pregnancy to full term. It effects over 5 millions couple alone in the U. S. and many times more in the world.

Coffee, becoming a popular and social beverage all over the world, particular in the West, is a drink made from roast bean from the Coffea plant, native to tropical Africa and Madagascar.

In a collected retrospectively on time of unprotected intercourse for the first pregnancy of a randomly selected sample of 3,187 women aged 25-44 years from five European countries (Denmark, Germany, Italy, Poland, and Spain) between August 1991 and February 1993, women drinking more than 500 mg of caffeine per day,  showed significantly increased odds ratio (OR) of 1.45, in risk of delay first pregnancy, in compared to women who consumed less than the maximum amounts.

The study also mentioned that, fertile women who are smokers and consumes over 500mg caffeine per day are associated higher related risk of 1.56 in compared to non smokers with same amounts of caffeine intake,

In first pregnancy, maximum or over maximum amounts of caffeine intake showed an increased time of waiting by 11%..

Other, in the examine of the retrospective study of 1,430 non-contracepting, parous women interviewed between July 1989 and June 1990 at Fishkill, New York, and Burlington, Vermont. and 2,501 pregnancies since 1980. Women's reported consumption of caffeinated beverage during the first month of pregnancy, range of daily caffeine intake of none, 1-150, 151-300, and > or = 301 mg with women who did not smoke and who consumed no caffeine used as a reference group, we found that women who drank none to 300 mg of caffeine showed a same relative risk of  in delay of conception among nonsmokers in compared to reference group.

Women, who do not smoke, intake more than 300 mg caffeine, showed a significantly increased delay conception odd ratio of 2,65.

Dr. Stanton CK, the lead author said, "Fecundability was reduced among nonsmokers who consumed more than 300 mg caffeine daily (fecundability ratio = 0.74, 95% CI 0.59-0.92)".

Interestingly, even though smoking reduced the ratio of delay conception, but caffeine consumption showed no effects on fecundability among women who smoked.

In support to the above differentiation, the Danish study also indicated that
nonsmoking women with a caffeine intake less than 300 mg/day in compared to nonsmoking women who consumed 300-700 mg/day of caffeine had a fecundability odds ratio (FR) of 0.88 against FR of 0.63 in higher consumption group.

The finding evidences suggested that women who want to get pregnant should reduce intake of caffeine to less than 300mg per day.
