Everything from heat to drugs to hormones to abuse during childhood can affect the number and health of sperm. Experts give tips on how to give a chance at fatherhood your best shot.
Studies underscore the importance of regular sex for sperm health, too. All kinds of factors play a role in sperm health, from the environment a man lives in, to what he eats, and even his mental health. While the study was small, fertility specialists agree that there has been a steady decline in sperm quality over the past 20 years, which could be partly explained by a stressful contemporary lifestyle and partly by stress in childhood.
Infertility is a widespread problem and while we frequently focus on compromised female ability to reproduce, which accounts for a third of cases, a third is caused by male fertility issues — and a third by both.
It is estimated that one in 20 men has some kind of fertility problem. A complete lack of sperm occurs in about 10 per cent to 15 per cent of men; a hormone imbalance or blockage could be responsible. In some cases, a man produces less sperm than normal. The most common cause of this is a varicocele — an enlarged vein in the testicle. Male infertility can be caused by complications that need medical intervention — varicoceles, tumours, infections, hormone imbalances, and physical defects such as undescended testes and blocked tubes, Ng says.
Sometimes, medical intervention itself, such as radiation Colds sperm and 90 days for cancer, X-rays and certain medications, may trigger problems. But there are a host of other factors that impact male fertility that can be addressed much more easily, and by the men themselves.
The testicles need to maintain a temperature about two degrees Celsius cooler than core body temperature. If the testicles are too hot for too long, sperm quality and quantity are affected. Dr Ng warns men not to keep radiation- and heat-emitting mobile phones in their trouser pockets.
Even sitting for too long can cause the testes to get too warm, so get up and get moving — the man-spread might not be genteel but it is healthier. Healthy sperm need a healthy diet. Dr Yik refers to a pair of Harvard studies. One found that men who ate between one and three servings of processed meats a day had worse quality sperm than those who ate the fewest servings.
Another found that men who ate fruits and vegetables with higher levels of pesticide residues had lower sperm counts Colds sperm and 90 days those who ate produce with lower pesticide residue levels.
Excessive alcohol use hastens the conversion of testosterone to estradiol — the primary female sex hormone. A study of 1, men found a link between obesity and a lower volume of semen, sperm count, concentration and motility how swiftly and strongly they swimand greater sperm defects.
Both experts warn that smoking, too, has been proven to reduce sperm count and motility.
So give up the cigarettes along with the booze and the bacon butties if you want to be a father. Dr Ng adds that overexposure to certain environmental elements such as chemicals, pesticides and heavy metals can affect sperm health. Drug use — recreational and prescription — can also affect sperm quality and quantity.
Marijuana might seem harmless but it can decrease testosterone levels in the testes. Opioids do the same.
Cocaine is among the worst as it constricts bloody supply, including to the testicles. Perhaps paradoxically, given that they are often used to promote a macho image, steroids are also hugely damaging. Without good testosterone production, your testicles start to shrink. The less time sperm spends in the testicles, the less likely it is to be damaged. Brief abstinences from sex, though, promotes sperm health — motility and morphology healthy shape.
Men need about 48 hours post-ejaculation to produce optimum amounts of sperm.
Having sex more frequently or much less frequently with long periods of abstinence can result in a lower sperm count and decreased sperm motility. Sperm needs time to recover in the libidinous energetic, but the longer you go without sex, the lazier sperm gets. Men with low levels of folic acid exhibit a higher rate of abnormal Colds sperm and 90 days in their sperm, and if such sperm fertilises an egg, it may result in miscarriage or birth defects.
More than half of first-trimester miscarriages are caused by chromosomal abnormalities in the embryo. A good multivitamin or foods that are high in folate — beans, leafy green vegetables, whole grains, citrus fruits, and folate-enriched cereals, breads, and pastas — Colds sperm and 90 days help reach the recommended daily dose of mg of folic acid. Tomatoes are a rich source of lycopene, an important antioxidant known to improve sperm structure and sperm count.
A single glass of tomato juice every day can be a powerful way to boost sperm count.
Adding olive oil to cooked tomatoes helps your body absorb lycopene. Eggs are one of the healthiest sources of protein and vitamin E. Regular consumption of eggs improve sperm count and motility and protect them from oxidative stress.
Berries — strawberries, blackberries, raspberries, and cranberries — are a rich source of vitamins and antioxidants. The anti-inflammatory properties of berries protect sperm from free radicals and help produce healthier, stronger sperm in higher volumes.
The Vitamin B6 and selenium in garlic play an important role in healthy sperm production. Garlic has cleansing properties, too, which remove impurities from arteries to improve blood flow; poor blood supply to the testes contributes to infertility.
It also contains zinc, which is known to increase testosterone, sperm motility and sperm count.
Aim to have 15mg of zinc a day. The food of love, chocolate also contains arginine, an amino acid that can improve sperm count and quality. Skip to main content.
