Why Bungoma boda boda riders should be worried

Wednesday June 14 2017

Spending longer hours riding a bicycle causes erectile dysfunction, a study among boda boda operators has shown.

The study done in Bungoma County and released last Friday, says that riding boda boda for longer hours can also cause prostate cancer and impotence.

According to the study done on 230 participants of whom 115 were sugarcane cutters and 115 bicycle taxi riders, commonly known as boda boda, riding in the gym can also cause trauma to the blood supply to the male organ, resulting in erectile dysfunction.

Impotence is the inability for one to sustain an erection sufficient for sexual intercourse or achieve an erection.

Dr Francis Kagema, a gynecologist and one of the authors of the study, said organic erectile dysfunction is common in elderly men but is not prevalent in men below 40 years of age.



“Recent research show that boda boda riding, smoking, alcohol intake and diabetes mellitus cause erectile dysfunction in much younger men,” said Dr Kagema.

The study was done to evaluate the effects of long term bicycle riding on erectile dysfunctions among boda boda riders in Bungoma town.

The main finding of this study, published in the East African Medical Journal last month, revealed that when one rides mechanical bike for long period, they are likely to affect the ability to ejaculate.

Dr Aggrey Akula, western Kenya lead gynaecologists said that the problem is not only in boda boda drivers but also truck drivers.

“This is as far as temperature is concerned. They sit on their testicles for long hence the rising temperature in the area which can make one impotent,” he said.


The overall prevalence of erectile dysfunction among bicycle taxi riders in the study was 36 per cent and 34 per cent among sugarcane cutters.

The risk of erectile dysfunction increased as the hours of riding per week increased.

“None of those who rode for more than 60 hours per week had a normal erectile function. The type of bicycle used was significantly associated with the quality of erection and hardness of erection score,” he said.

Those who used mechanical (none motorised) bicycles had an increased risk of erectile dysfunction.

A British study also revealed that middle aged men who spend nine hours a week on their bike are more likely to be diagnosed with prostate cancer.

But the statistical link with prostate cancer could create a new, and unexpected, health concern for the millions of men who cycle regularly.
