Yes, high blood pressure is a precursor for erectile dysfunction affecting the majority of men with chronic cardiovascular or systemic diseases.
Erectile dysfunction is commonly known as impotence.
And it is a disease in males characterized by the inability to obtain and maintain a healthy erection.
Many underlying lying causes precipitate the occurrence of erectile dysfunction such as co-morbidities, addictions, psychosocial stress, and drug side effects.
The percentage of erectile dysfunction is more in older adults as compared to the young ones.
However, it can also occur in the young ones owing to other relatable factors.
Blood pressure also plays its role and is often associated with causing systemic diseases or a risk factor for circulatory pathology.
Blood pressure has its ranges from normal to highly pathological values.
A blood pressure range of 90/60mmHg to 120/80mmHg is normal and below 90/60mmHg falls in the category of low blood pressure.
High blood pressure starting from 130/89mmHg and above falls in the first stage of hypertension and above 140/90 is called the 2nd stage of hypertension.
Mechanism of an Erection and Where The Problem Lies:
A sound amount of blood flow to the erectile organ is required to cause an erection.
In response to a sexual stimulus, the cavernosal muscles in the penis relax that open up the cavernosal sinuses.
At the same time vasodilation of the vessels to the genitals occurs resulting in a rush of blood to fill these sinuses.
An enzyme Phosphodiesterase type-5 (PDE-5) causes the contraction of smooth muscles in the arterial walls.
It happens by reducing the levels of cyclic Guanosine monophosphate (cGMP) responsible for smooth muscle relaxation.
These events collectively lead to a healthy erection, but any blockage of blood to the erectile tissues tends to not causes a healthy erection in men with erectile dysfunction.
Tadalafil is a Phosphodiesterase type-5 inhibitor that blocks the PDE-5 enzyme and improves circulation to the penis.
What Could Be The Possible Causes of Reduced Blood Flow?
- A blocked artery as a result of injury or embolism
- Blocked veins due to varicosities, as in the case of varicocele.
- Failure of vasodilation in scenarios where a brain lesion does not allow the signals to pass to the vessels.
- Hormonal imbalance causing a prolonged vasoconstriction
- When the cavernosal muscles are unable to relax.
How is Hypertension Responsible For Erectile Dysfunction:
A patient with hypertension has very small or narrow arteries with a reduced blood flow to the organs.
That is why hypertensive individuals have slow internal body functions and slow metabolism.
As by now, we understand that blood flow tot the penis is required to obtain an erection.
And in hypertension, the blood flow to the penis is reduced because of three reasons,
- Reduced oxygenated blood inflow: Constricted arterial walls and narrow arterial lumen reducing the circulation of oxygenated blood.
- Reduced deoxygenated blood outflow: The venous return and drainage of deoxygenated blood away from the penis are reduced.
- Testosterone decline: A decile in the amount of testosterone occurs due to high blood pressure.
Testosterone is the hormone for sexual arousal in men, and its deficiency can lead to a lack of interest with consequent failure of erection.
The production of testosterone may remain good but due to lack of circulation testosterone hormone cannot reach its target site.
Or even if it reaches the amount is not enough for arousal.
Treatment For ED:
One of the most effective options of treatment for erectile dysfunction is Tadalafil that is sold under the brand name Cialis.
It blocks the PDE-5 enzymes, increasing the blood flow to the genitals so that an erection is easy to achieve and maintain for a longer time.
