Can Soft Drinks Have a Negative Effect on Fertility?

Can Soft Drinks Have a Negative Effect on Fertility?

Research now suggests that when a couple is trying to conceive, not only should both the male and female quit smoking and reduce their alcohol intake, they should also stop consuming soft drinks, because these sugary drinks may reduce their chances of conceiving.

A study of 3800 women and 1000 of their male partners revealed that women who had a minimum of one soft drink per day had a 25% lower monthly probability of conception, while the partners of men who consumed the same amount were 33% less likely to conceive. The study did not include diet soda or fruit juices; but interestingly, when a couple consumed energy drinks their fertility was reduced even more.

The last half of this century has seen a large increase in the amount of sugar added to the average diet, with one third of the total sugar intake coming from sugar-sweetened drinks, like soda. This overload of sugar is associated with Type 2 Diabetes and weight gain. Interestingly, consuming soft drinks has also been tied to poor semen quality and early menstruation.

What the Experts Say

Professor of Epidemiology, Elizabeth Hatch, said that positive associations were found between lower fertility and the intake of sugar-sweetened beverages. These results were consistent after researching other factors, including caffeine intake, obesity, smoking, alcohol, and overall diet quality. Her advice was that couples trying to conceive should consider reducing (or quitting) their consumption of these types of drinks.

A Melbourne based gynaecologist, obstetrician, infertility and IVF specialist, Doctor Joseph Sgroi, said he believed couples should not consume soft drinks while trying to conceive. His reasons were that soft drinks increase insulin levels, which might place you in a prediabetic range, thus affecting fertility. Dr Sgroi suggested drinking water, maintaining a healthy weight, regular exercise, decreasing alcohol intake, stopping smoking, and avoiding all drugs of substance in order to optimise a couple’s chances of getting pregnant.

In another study, 524 patients were tested, and it was determined that there is a link between artificial sweeteners and lower fertility rates. It was also determined that the sugar consumed in coffee and soft drinks leads to poorer quality eggs and embryos.

A leading fertility expert in Britain warned that women who are trying to conceive should never underestimate the effects that food additives can have on their ability to conceive.

Why Are Soft Drinks so Detrimental to Fertility?

Sugar

Did you know that a single can of soft drink contains approximately 10 teaspoons of sugar? This is more sugar than almost anything else you consume. Consumption of this huge amount of sugar results in fluctuations of your hormones and blood sugar. It’s also linked to poor dental health, obesity, and diabetes. So it’s probably safe to say that consuming so much sugar is going to undermine not only your general health, but also your fertility.

Aspartame

Many people concerned about the amount of sugar they were consuming stopped drinking soft drinks and switched to diet soda, but this in itself is a problem. The sweetener Aspartame is used in diet sodas, and this product has been connected to a number of health issues. When referring to fertility and pregnancy, it’s now believed that Aspartame can be linked to miscarriages and infertility.

Obesity

Any couple trying to conceive should endeavour to maintain a healthy body weight. Eating a healthy diet and maintaining a healthy weight gives a couple the best chance of conceiving, maintaining a healthy pregnancy, and producing a healthy baby. Eliminating soft drinks is possibly one of the easiest ways for an overweight or obese person to reduce excess calories and sugar. The calories you save can now be invested in nutrient-rich foods.

Caffeine

It’s still not entirely clear what the effects of caffeine are on fertility; however, many studies suggest that an ovulation cycle can be affected by the consumption of caffeine because caffeine consumption can lead to irregular hormone levels. Many women trying to conceive either reduce or completely cut out caffeine both while trying to conceive and during their pregnancy. It’s very important to point out here that caffeine is found in many sodas, like Cola.
