Oh no... Back in 2017 a large study found that male sperm counts had dropped over 50% since the 1970s in North America, Europe, and Australia. Declining every year, year after year, for over 40 years. This has serious implications for fertility - if sperm counts drop too low, it's very difficult to conceive a baby.
Now those same researchers have published data from 53 countries showing that the sperm count decline is also occurring in Asia, South America, and Africa. And that the decline in male sperm counts is actually accelerating in North America and Europe. Yikes!
Note that this is in men who weren't being screened for fertility problems issues. In other words, random healthy men. Some had already fathered a baby.
Globally, the decline was about 1.16% per year from 1973 to 2018 (resulting in a 52% decline). When the researchers reexamined the data and looked at many more studies, they realized that since 2000 the decline accelerated at 2.64% per year.
Average global sperm concentration was 49 million per milliliter of semen in 2018. The researcher Dr. Swan pointed out that when sperm count drops below roughly 45 million per milliliter, the ability to cause a pregnancy begins to plummet dramatically, and at 40 million and lower the chances of conception are very low without reproductive assistance (e.g., IVF).
Interestingly, sperm counts are not just a male fertility issue, but also an indicator of men's health. Low levels of sperm are associated with increased risk of chronic disease, testicular cancer, and a shorter lifespan. With a decline in sperm numbers there is also a decline in testosterone and male genital anomalies - thus a decline in male reproductive health.
Why is this happening? Several possibilities are probably contributing: mainly lifestyle and also all the chemicals and plastics in our lives (environmental chemical exposure). Endocrine disruptors, phthalates, pesticides! Yes, they are all around us - in the air, the water, consumer products, and our bodies.
Some examples: pesticides, flame retardants, stain and water resistant products. Plastics leach and outgas and we get them into us various ways (skin, inhale them, ingest them in our foods and water). List of ways to reduce exposure to harmful chemicals.
THINGS YOU CAN DO TO IMPROVE SPERM COUNT AND HEALTH:
Lifestyle: Don't smoke. Don't drink or drink very little. Don't do drugs. Don't sit in hot tubs or saunas. Get exercise or physical activity. Eat a diet rich in fruits, vegetables, whole grains, legumes, seeds, nuts. Avoid canned foods, minimize fast food take-out. Eat as much organic as possible. Lose weight, if needed.
Chemical exposure: We can't totally avoid all the chemicals, but we can minimize our exposure. For starters, stop using non-stick cookware, avoid pesticides in the home and yard (look for nontoxic alternatives and view weeds as wildflowers), don't use dryer sheets, buy unscented products (and avoid fragrances). List of ways to reduce exposure to harmful chemicals.
An international team led by Professor Hagai Levine of Hebrew University of Jerusalem's Hadassah Braun School of Public Health, with Prof. Shanna Swan at the Icahn School of Medicine, Mount Sinai, New York, along with researchers in Denmark, Brazil, Spain, Israel and the USA, published the first meta-analysis to demonstrate declining sperm counts among men from South and Central America, Asia and Africa. ...continue reading "Sperm Counts Are Still Dropping Throughout the World"
