TV Viewing Linked to Low Sperm Quality.

sperm_640Over the last few decades, researchers have discovered that sperm quality has deteriorated. Nonetheless, it’s unclear why this phenomenon is happening.

In an article published in the British Journal of Sports Medicine, researchers set out to determine if a sedentary lifestyle may be a contributing factor to poor sperm quality. For the study, the semen quality of 189 men between the ages of 18 and 22 were examined. Side note: Sounds like a fun job.

Participants were asked a number of questions about the quantity and intensity of weekly exercise, how much time they spent watching TV and movies, reproductive health problems, diet, stress, smoking status and more.

According to the data, the most physically active men (15+ hours a week of vigorous exercise), had a 73% higher sperm count than the least physically active. Notably, exercise didn’t affect other sperm factors like shape, motility or sample volume (lol). Low intensity exercise didn’t affect sperm count.

According to the study:

In this population of healthy men, higher moderate-to-vigorous activity and less TV watching were significantly associated with higher total sperm count and sperm concentration.

For future studies, researchers want to evaluate how different types of exercise affect sperm quality. So… more to come. Pun intended.

    This deterioration of sperm quality is also being investigated as to whether there is a link to certain conditions like autism, birth defects ect. Autism is now effecting 1 in every 10 boys born.

  2. There is also a recent study that looks into how sperm quality and quantity is affected by laptops and wi-fi signals. The study concluded that wi-fi signals affected sperm motility and quality when in close proximity to the testes — like having your laptop on your lap for long periods of time.

    Since the study you referenced sampled only 18 to 22 year olds, I’m guessing many of them are college students with laptops. I wonder if that is part of it.

    And don’t forget the ever-present “smart” phone in your front pocket (guys), right next to your gonads and lymph nodes, with the signal emitting radiation 24/7. It hasn’t been proven cancerous? Cell phones are safe? You each have this one life and you’re going to voluntarily subject it to experimentation? Not me. I don’t need to stay in touch that badly.
