Some research shows that caffeine is associated with a decrease in sperm quality, especially when consumed in excess; other studies demonstrate that moderate caffeine consumption might actually be good for sperm. Caffeine intake may negatively impact a couple's chances of conception.
Coffee drinking was correlated with increases in sperm density and percentage of abnormal forms. Among non smokers, coffee drinkers had a higher percentage of motile sperm as compared to non-coffee drinkers.
Spinach and Carrot Juice: A winning combination of vitamins A, C, and E, as well as folic acid, which are essential for sperm health. Beet and Apple Juice: Packed with nitrates that improve blood flow and antioxidants that protect sperm from damage.
Men who consume moderate amounts of caffeine showed no real impact on sperm health. A small cup of coffee can help with sperm motility. However, excess use can decrease sperm quality and fertility.
Curb caffeine. Female fertility doesn't seem to be affected by caffeine intake below 200 milligrams a day. Consider limiting your caffeine intake to one or two 6- to 8-ounce cups of coffee a day. Be wary of overexercise.
Although researchers haven't been able to find a clear connection between moderate caffeine intake and fertility problems, it's generally considered safe to consume 200 to 300 milligrams (mg) of caffeine daily while trying to conceive.
Some research suggests that increasing body mass index (BMI) is linked with decreasing sperm count and sperm movement. Eat a healthy diet. Choose plenty of fruits and vegetables, which are rich in antioxidants — and might help improve sperm health. Prevent sexually transmitted infections (STIs).
Lifestyle choices can lower sperm numbers. Smoking, drinking alcohol, and taking certain medications can lower sperm numbers. Other causes of low sperm numbers include long-term sickness (such as kidney failure), childhood infections (such as mumps), and chromosome or hormone problems (such as low testosterone).
Caffeine generally has a positive impact on testosterone levels. It has been shown that men that consume caffeine on a regular basis, on average, have more testosterone than those that don't. Not only this but the estradiol levels, both free and total, have been reduced.
Overheated testicles and tight clothing.
Since testicles, which store sperm, are outside of the body, they are vulnerable to heat. That means prolonged and regular use of hot tubs is not recommended as the heat can kill sperm cells.
Caffeine intake may have a negative impact on male fertility, including sperm count and testicular function, especially when used in excess and when found in sugary beverages like cola and energy drinks.
Caffeine Affects Men as Well
While a few cups of coffee, tea, or cola aren't known to have an impact on the father's fertility, caffeine in excessive amounts, such as that found in 4-6 cups of coffee per day (400 mg) or more can lower sperm counts.
Sodas and energy drinks
Similarly, energy drinks have been linked to decreased semen quality, with the impact of these drinks increasing in line with the number of energy drinks men consumed. These, too, can reduce sperm count, making it more difficult for males to conceive.
A trained expert checks your sperm count, their shape, movement, and other characteristics. In general, if you have a higher number of normal-shaped sperm, it means you have higher fertility. But there are plenty of exceptions to this. A lot of guys with low sperm counts or abnormal semen are still fertile.
Certain factors, however, can contribute to a reduction in male ejaculate, including your age, particular medications, or even a surgical procedure you've had. Experts note that low testosterone levels, which affect about 5 million American men, can also result in the release of less semen during ejaculation.
Men start losing their fertility at age 40.
In a study of more than 1,900 couples, irrespective of the woman's age, IVF attempts involving men 40 or older failed 70 percent more often than IVF attempts involving men younger than 30. Previous theory: Older men produce fewer kids because they get less sex.
Normal semen is generally a clear, white, or gray color. Changes in its color may be temporary and may resolve without medical treatment. However, if people experience changes in semen that do not go away or come with other symptoms, such as infection or inflammation, they should seek medical attention.
Some studies suggest that moderate ejaculation (2–4 times per week) is associated with a lower prostate cancer risk. However, ejaculating more often doesn't mean your cancer risk drops even more.
Men, nutrition and fertility
Diets rich in fruits, vegetables, wholegrains and fish are linked to better sperm quality. Eating a portion of walnuts a day was shown to help with sperm motility (ability to swim).
Several studies have shown that coffee (even decaffeinated coffee) can diminish fertility. One Dutch study showed that 4 cups of decaf or regular coffee a day lowered a woman's* chance of having a baby by 25%. Some studies have linked coffee to miscarriage and some have linked it to low sperm count.
