The nature of the physiological mechanism of the appearance of an erection is directly related to many chemical reactions occurring in the reproductive system when sexual stimulation takes place. The chemical reaction consists of a series of successive links, the beginning of which is the release of NO from the epithelial cells of the cavernous bodies, and then the production of cGMP is automatically increased, which leads to a relaxation of the smooth muscle tissue and the vascular system of the penis. The penis is filled with blood as much as possible, and there is a permanent erection. Directly confronted with the potency of the enzyme PDE5, it is Sildenafil contained in generic Viagra can effectively restrain its amount, and thus provide a reliable and long lasting erection.
Generic Viagra is not a hormonal drug, its mechanism of action is entirely different, affecting only the humoral mechanisms. The main effect is a local increase in blood flow to the genital organs. The highly selective action of generic Viagra, only exclusively on the reproductive system and does not affect the work of other organs and systems in the body, which avoids the side effects inherent in these groups of means against impotence.

The Influence of Excess Weight on the Potency
The problem of erectile dysfunction among fat men occurs twenty-five times more often than among sportsmen of the stronger sex. With obesity, it is not easy to achieve a normal erection, but also reduces the quality and volume of sperm, which can make a man barren. What is the reason for this? Let’s consider the main causes of impotence in obesity.
- Disturbed hormonal balance. The subcutaneous fat layer actively synthesizes the sex hormones of women (which is why many women are advised to gain weight for ease of conception because the fat layer is physiological for a woman). At first, the male body struggles with the excess of female hormones and therefore produces a more male hormone, but in the future, if the weight of a man does not decrease, the body’s strengths are depleted, and the amount of testosterone produced decreases dramatically. As a result, the man notices an erection insufficient for sexual intercourse, too fast ejaculation and many other difficulties. Female sex hormones are formed in the male body, not only with the “assistance” of subcutaneous fat.
- Vegetable estrogens (isoflavones) in large quantities are contained in hops (in beer) and many sausages. These products are among the most dangerous, as their regular consumption very quickly leads to obesity and, as a consequence, to erectile dysfunction.
- Development of many concomitant diseases. Since obesity has a very negative effect on the entire male body as a whole, it becomes more prone to many other dangerous diseases. Among the most common concomitant diseases, it is possible to distinguish arterial hypertension and diabetes mellitus. Due to the development of diabetes, the man has a decrease in the sensitivity of the groin and penis area, disrupting the work of the brain region, which regulates erectile function and sexual desire.
The most terrible situation for a man is the combination of diabetes, obesity, and hypertension, which together constitute a metabolic syndrome, which is extremely difficult to treat. Generic Viagra can be taken when a patient is treating obesity.
