Laptop computers can cause male infertility. Here is what one reproductive specialist says about the link between male infertility and the excessive use of laptops – plus several tips for overcoming male infertility.

According to Loyola, 40% of fertility issues are attributed to males. Causes of male infertility include varicocoeles (enlarged varicose veins in the scrotum, which can raise the temperature in the testicles and damage or kill sperm), genital injuries or defects, certain sexually transmitted infections, prostatitis (an infection or inflammation of the prostate), immune and hormonal disorders, and erectile dysfunction.

And, here are tips for overcoming male infertility caused by laptop computers…

The Link Between Male Infertility and Laptop Computers

“Laptops are becoming increasingly common among young men wired into to the latest technology,” said Suzanne Kavic, MD, director of the division of reproductive endocrinology at LUHS and associate professor in the department of obstetrics and gynecology and department of medicine at Loyola University Chicago Stritch School of Medicine.

“The heat generated from laptops can impact sperm count, production, and development making it difficult to conceive down the road.”

Tips for Overcoming Infertility Caused by Laptops

  • Place laptop computers on desktops to prevent damaging sperm and decreasing counts and motility.
  • Avoid hot tubs
  • Use boxers over briefs
  • Refrain from ejaculating too frequently (the recommendation is to only engage in intercourse every other day around ovulation)
  • Exercise moderately (one hour, three to five times per week)
  • Avoid exercise that can generate heat or trauma to the genital area
  • Eat well
  • Take vitamins and nutrients to increase fertility
  • Get eight hours of sleep per night
  • Stay hydrated and limit caffeine to no more than two cups per day
  • Refrain from smoking
  • Avoid drugs and excessive alcohol use
  • Minimize exposure to toxins
  • Avoid excessive weight gain or weight loss
  • Practice stress reduction techniques for infertility

Other causes of male infertility

“Medications for depression, blood pressure and certain heart conditions may lower libido or cause impotence,” said Kavic. “Men should talk with their physicians to see if medication is necessary or if they can switch to another with fewer side effects.”

  1. Thanks, I agree that weight does play an important role in fertility issues and getting pregnant. I suspect the laptop use isn’t as detrimental to sperm health as other things – especially genetics!

  2. Hi

    General maintenace of your health plays a major factor in these situations and sometime a trip to the doctor to get the dredded news, “its your weight” can sometime be the first step. I;ve seen many lives changed by turning denial into acceptance and then doing something about it. I run a site dedicated to maintaining good health, and have a section dedication to this proplem. Take a look

  3. Men who are infertile appear to have an increased risk of developing testicular cancer, according to a report in the Archives of Internal Medicine, one of the JAMA/Archives journals.

    Testicular germ cell cancer, the most common cancer among young men in industrialized countries, has become even more prevalent during the last 30 to 50 years, according to background information in the article. There is evidence that semen quality and male fertility have also declined during this time in industrialized nations; however, it is unclear whether these two trends are related.

    Thomas J. Walsh, M.D., M.S., then of the University of California, San Francisco, and now of the University of Washington School of Medicine, Seattle, and colleagues analyzed data from 22,562 male partners of couples seeking fertility treatment between 1967 and 1998 (4,549 of whom had male factor infertility, based on a clinical presentation with abnormal semen analysis criteria). Their records were linked to the state cancer registry, which includes information about cancer cases confirmed between 1988 and 2004.

    A total of 34 of the 22,562 men were diagnosed with testicular cancer at least one year after seeking treatment for infertility. Compared with men of the same age in the general population men in couples seeking treatment for infertility were 1.3 times more likely to develop testicular cancer. Men with male factor infertility were 2.8 more likely to develop testicular cancer than those without this condition.

    “In interpreting these data, we considered the postulate that male factor infertility or its treatment could cause testicular cancer,” the authors write. “However, this theory is highly improbable given that in many cases infertility treatment involves the use of assisted reproductive technologies rather than specific medical or surgical treatment of the male partner.”

    “A more plausible explanation is that a common exposure underlies infertility and testicular cancer,” the authors conclude. Faulty DNA repair, or errors in the way the body responds to small areas of damage in its genetic material, may contribute to both conditions, as may environmental factors.

  4. Increasing male age is a factor in some male infertility and damage sperm of an older male can produce autistic or schizophrenic offspring in families with no prior history of the disorders.
