15 Ways to Prevent Declining Sperm and Testosterone Level

A recent meta-analysis from the Hebrew University of Jerusalem notes that sperm counts, or the concentration of sperm in ejaculate, among men have declined by a little more than 52 percent over the last four decades.

The study’s authors were careful to look only at research that did not involve men known to have infertility problems and that used the same sperm counting method. They also waffled on the reasons why the decline is happening. Altogether, the meta-analysis looked at 185 studies that involved nearly 43,000 men from western countries (including Australia, Europe, North America, and New Zealand) or from elsewhere.

The authors reported the following findings:

• Sperm concentrations have fallen from 99 million per milliliter in 1973 to 47.1 million per milliliter in 2011

• Among the same men, total sperm count (the number of sperm in a sample of semen) declined by nearly 60 percent

• The authors also noted a less dramatic drop in sperm concentration among western men who had conceived with a partner.

According to Richard Sharpe, professor at the University of Edinburgh and an expert in male reproductive health, researchers are still not certain what the reason is for the decline in sperm. Allan Pacey, professor of andrology at the University of Sheffield, said “We have got very little epidemiological evidence to say what might be causing it [the decline in sperm concentration], so we are still scratching our heads a little bit in my view.”

Why sperm counts are declining

For example, a 2014 article in Frontiers in Public Health pointed out that the banned substance polychlorinated biphenyls (PBCs) can interfere with the production and development of sperm. Another study found that BPA (bisphenol A), a substance found in many plastics, can cause sperm DNA damage. Various studies have identified phthalates (another common plastic component) and their metabolites as disrupting sperm production, quality, concentration, and motility.

Other damage to males from environmental pollutantsIn a report from the Endocrine Society, experts warned that exposure to high levels of phthalates, which are found in personal care products and plastics, can reduce testosterone levels. In particular, the authors noted that reduced T levels were associated with increased exposure to phthalates in several populations, including boys, ages 6 to 12, and men, ages 40 to 60. Disrupted testosterone in young males can have a negative impact on their reproductive development, while low T in later years can affect libido, energy, cognitive function, sexual performance, and bone health and contribute to the formation of man boobs.

How to avoid BPA and other endocrine disruptors

To help maintain sperm health as well as testosterone levels, avoid endocrine disruptors whenever possible.

1. Check labels on personal care products for the presence of chemicals such as phthalates, parabens, and others. In fact, it is best to stick to all-natural shampoos, lotions, after shave, soaps, and similar products.

2. Select products without fragrance, as phthalates are typically found in fragrances.

3. Choose organic produce, grains, low-fat dairy, meats, and beverages whenever possible to avoid exposure to pesticides.

4. Buy fresh or frozen fruits and vegetables, not canned.

5. Steer clear of BPA by not using plastic food containers or water bottles. Always avoid plastics with the numbers 3, 6, or 7; safer numbers are 1, 2, and 4.

6. Avoid foods and beverages in cans, as BPA can leach into the contents. Choose glass containers or frozen foods instead.

7. Use all-natural cleaning products.

8. Say no to sexual lubricants, which can disrupt hormones. Try coconut oil instead.

9. Filter your water to help reduce phthalate content.

10. Heat and store food in stainless steel, ceramic, and/or glass–no plastic!

11. Steer clear of plastic toys for infants and children and sex toys for adults.

12. If you don’t know whether a product is BPA or phthalate free, contact the manufacturer and ask.

13. Choose safer options than plastic wrap, such as parchment paper, glass jars, or ceramic containers.

14. Always bring your own coffee or other hot beverage mug, as disposable paper cups are typically lined with plastic.

15. Ask your dentist whether she or he uses BPA-free sealants or composites.
