Does Caffeine Affect Conception?

Does Caffeine Affect Conception?


Studies show that caffeine may have an effect on conception.

More Info: Does caffeine affect conception? That question is hard to answer. There are so many contradicting medical studies that the answer to whether or not caffeine consumption can lead to infertility remains a little vague.

Caffeine Is a Stimulant

One thing that all of the medical professionals agree on is the fact that caffeine is a stimulant. It has a broad range of effects on the body under normal conditions. It is known to increase blood pressure and disrupt sleeping patterns. It also plays a key role in upsetting the digestive system and kidneys. With these stressors on the body, doctors suspect that caffeine might play a key role in delayed conception as well.

Ingesting Caffeine Delays Conception

Medical studies have shown that women who regularly ingest large quantities of caffeine experience delayed conception. In these studies, it took women a year or longer to successfully become pregnant than women who did not ingest high amounts of caffeine. The theory that the medical studies have come to is that caffeine may interfere with the eggs ability to implant to the uterine wall and begin developing. Doctors also suspect that once an egg is attached and growing, caffeine may have an effect on the baby’s ability to draw the nutrients and oxygen from the placenta.

Caffeine Has Negative Effects on Pregnancy

Though it is still unclear in the medical field how caffeine may affect conception there is one thing that the doctors agree on, caffeine can have negative effects on pregnancy. It has been well documented that the consumption of caffeine during pregnancy can increase a woman’s chance for miscarriage. Caffeine may also play a role in other complications such as low birth weight. With all of these negative aspects of caffeine consumption, there is one piece of advice that stands true. Once a woman has decided to conceive, cutting out the caffeine should be part of that pre-conception regimen.
