Erectile Dysfunction

Erectile dysfunction, sometimes called "impotence", is the repeated inability to get or keep an erection firm enough for sexual intercourse.


Erectile dysfunction is resulted because the blood flow into the penis is not enough to make it expand to sustain an erection. 

Erectile dysfunction can be caused by physical factors, psychological factors or sometimes a combination of them.  Some of the factors are as follows:

  • High blood pressure
  • High cholesterol level
  • Diabetes
  • Nervous system disease
  • Previous injury to pelvis or spinal cord
  • Stress or anxiety
  • Fatigue
  • Depression

Unhealthy lifestyle habits like smoking, alcohol and drug abuse and taking certain prescription medications may lead to erectile dysfunction.

Actually, inability to maintain an erection firm enough for sex on an occasional basis can be normal.  Since fatigue, getting not enough sleep and mental stress may affect penis erection.


Erectile dysfunction is treatable in most cases.  Making the following healthy lifestyle changes is important as it may help regaining sexual ability:

  • Take a balanced diet, increase physical activity, get more sleep and be relaxed
  • Do not abuse drugs
  • Avoid excessive alcohol
  • Stop smoking

Treatments for erectile dysfunction include taking oral medications (e.g. vasodilators or male hormones), injecting medications directly into the penis, using vacuum device to make penis erect, implanting a pump under the skin of penis, having counseling by psychologist or counselor etc.  You should always seek advice from your doctors in order to choose the most suitable treatment option.

The most commonly used medications for treating erectile dysfunction is a class of drugs called phosphodiesterase (PDE) inhibitors including Sildenafil, Tadalafil and Vardenafil.  They work by relaxing the muscles in the penis upon sexual stimulation to increase blood flow to achieve an erection.

Common side effects are headache, facial flushing, dizziness and temporary vision blurring etc.  Men who take nitrate-based drugs should not take these medications because the combination can cause a sudden drop in blood pressure.  Men with heart disease, history of stroke or heart attack should seek medical advice in advance.

According to the Pharmacy and Poisons Ordinance, Chapter 138, Laws of Hong Kong, a product containing Sildenafil, Tadalafil or Vardenafil must be registered before it can be sold in Hong Kong.  It can be sold only on a doctor’s prescription and dispensed under the supervision of a pharmacist.

From time to time, the Department of Health receives reports of persons feeling unwell after consuming virility products with undeclared western drug ingredients that are purchased while traveling abroad.  Recently, some products offered for sale on the internet were also found to contain undeclared western drug ingredients.  

Products not registered according to the Pharmacy and Poisons Ordinance are potentially harmful as their safety, efficacy and quality cannot be ascertained.  Members of the public should not buy products of unknown or doubtful composition and source. Persons who have sexual dysfunction should consult medical professionals and not to use any unevaluated product.
