Coffee Bean.

Coffee is a delicious treat that can get your morning going. I know that I can’t start my day without a hot cup of joe. It’s fair to say I am addicted to the stuff. In fact, with coffee being such a huge industry I don’t think I am the only one that loves the stuff. When you drink as much coffee as I do, you wonder about the health effects and how it can impact your life. So I did some research on what the long term effects of extensive coffee use may be. I found that many people are concerned about coffee affecting fertility. Specifically having a large impact on male fertility. So iIlooked it up. So does coffee have an impact on the fertility of men? Well, I am going to show you what I found.

Does Coffee Affect Male Fertility?

Coffee is a drink that is comprised of a number of components in it, but the primary active ingredient is without a doubt caffeine. Caffeine is what gives coffee its punch and is what most people drink the stuff for in the first place. So it is no surprise that caffeine is the primary suspect when it comes to affecting male fertility.

Coffee Bean.

Research done on the effects of caffeine on male fertility and sperm at the University Department of Growth and Reproduction at Rigshospitalet in Copenhagen, Denmark found some interesting things out about the differences in caffeine delivery systems.They found that there is a difference in some caffeine based drinks when it comes to the impact on male fertility and sperm counts. Their research showed that people that would drink high levels of soda based caffeine drinks showed significantly lower sperm counts than those that got their caffeine from coffee and tea drinks.

Further research that was conducted out of Massachusetts General in Boston showed that men who consumed 265 mgs of coffee or more had far less chance of becoming a father. This was confusing findings at first because they did not note a significant change in sperm count or quality of the sperm. The thought is that there may be some mutation going on in the sperm themselves. The research here still showed that drinks like coffee and tea are still your best options in this sense, and cola and energy drinks have the largest effects on male fertility.


Like most things you can consume, there will be significant effects on your body, and caffeine is no different. The key to all things is moderation. And the more natural delivery systems are, the safer routes. If you are drinking coffee for your caffeine, you are going to watch the amount you consume. The research would suggest that typically if you stick to three or fewer cups of coffee, you will be unchanged in the fertility department. After three cups of coffee, you start to increase the chance of mutations to sperm produced. In fact, the research suggests that a man that drinks this increased amount of coffee, he will have a one in five chance of getting a woman pregnant.

Another interesting link between caffeine and fertility is the link between plural birth. It turns out that regular consumption of coffee in regulated amounts (about one cup a day for long periods of time) is linked with twins and triplets. The rate of pregnancy also goes up when using artificial insemination. A man that drinks this moderate amount of coffee will increase his chances of conceiving by about 52 percent when using artificial insemination. So if you want lots of kids, drink one cup a day, if you want no kids, three or more cups may be for you. Even though one cup of coffee does seem to energize the sperm in the short term, which makes it good for artificial insemination, it shortens the life of the sperm, so for traditional impregnation, you may notice an actual decrease in the rate of pregnancy. The extra energy provided to the sperm shortens the viability of them. They are much faster in laboratory conditions but take longer to reach eggs, if they even can.


In general, it seems that caffeine from different places affects fertility differently. It seems that drinks such as energy drinks and soda can actually reduce sperm counts, but coffee and tea do not. But there is still a change in the rate of pregnancy. So what is happening to the sperm that causes this change if there is not a reduction in the count of the sperm? Well, it is thought that caffeine itself may actually harm sperm on a molecular level. This is why it can appear that there is a high count, and they appear healthy, but they just don’t take and reduces the rate of pregnancy in men that drink too much caffeine. This is double for soda and energy drinks, as they can not only reduce the count but damage the sperm that it produced.

The damage to the sperm is actually represented in an increase in potential defects in their genetics. The damage to the sperm is serious, and the passed down chances of developmental problems should be taken seriously. If you choose to continue drinking coffee while you try to conceive, keep these in mind.

All this means, that if you are a hopeful father, you should consider monitoring your coffee drinking habits. Maybe stick to a small amount of coffee every day if you are interested in artificial insemination, and stay away from soda and energy drinks. Do not drink coffee to access as all of these things can negatively affect the chances of you helping conceive a child.

A Risk

There are many things that caffeine seems to do to a man’s ability to reproduce. Soda and energy drinks reduce sperm counts, while teas and coffees do not. Although coffee does seem to change the way that the sperm behaves. In laboratory conditions, small amounts of coffee seem to help with the rate of impregnation in labs and artificial insemination, but in the long term, it is still damaging to the sperm. High levels of coffee definitely reflect this, by reducing the chance of insemination greatly. In the end, it is the best to reduce coffee consumption if you are looking to be a father.
