Introduction
Erectile dysfunction (ED), commonly referred to as impotence, is a condition where a man experiences difficulty in achieving or maintaining an erection sufficient for sexual activity. In simpler terms, it’s the inability to sustain an erection during sexual encounters. Although this issue can be frustrating and embarrassing, it is a common condition that many men face at some point in their lives.
ED can arise from various causes, including physical health problems, emotional or psychological challenges, and lifestyle factors. Identifying the precise cause may not always be straightforward, but recognizing that it is a widespread issue can help reduce stigma and foster open discussions about sexual health. Many men successfully manage and overcome ED by seeking appropriate medical advice and addressing its underlying factors. Best Doctor for Treatment of Erectile Dysfunction in Delhi
Definition of ED
Erectile dysfunction, or impotence, is defined as the persistent inability to achieve or maintain an erection firm enough for satisfactory sexual intercourse. It is a multifactorial condition influenced by physical, psychological, and lifestyle factors. The severity of ED can vary from mild to severe and may be temporary or chronic.
Global Statistics for ED
According to the World Health Organization (WHO), approximately 150 million men worldwide are affected by erectile dysfunction, a number projected to rise to 322 million by 2025. The global prevalence of ED varies across regions, ranging from 3% to 76.5%. The Massachusetts Male Aging Study (MMAS) reported an overall prevalence of 52% in men aged 40-70 years, with 17.2% experiencing mild, 25.2% moderate, and 9.6% severe ED.

Rising rates of chronic diseases such as diabetes, hypertension, and obesity
Increased awareness and reporting of sexual health issues
Indian Statistics for ED
In India, with its vast population and diverse demographics, ED presents a significant health burden. A study in the Indian Journal of Urology estimated that around 50% of Indian men aged 40-70 years experience some degree of ED. Another study spanning eight Indian cities found a 49.5% prevalence in men aged 18-75 years.
Key factors influencing ED prevalence in India include:
Age
Urbanization
Education levels
Socioeconomic status
The association of ED with comorbidities such as diabetes, hypertension, and heart disease is notable. Approximately 50% of diabetic men in India suffer from ED. Cultural stigma surrounding discussions of sexual health in India often leads to underdiagnosis and undertreatment. A 2019 survey revealed that only 10% of Indian men with ED sought medical assistance, and just 50% of those diagnosed received treatment. BEST SEXOLOGIST DOCTOR IN DELHI
Physiology of Erection and Pathogenesis of Erectile Dysfunction
Understanding the physiological mechanisms behind erections and the factors leading to ED is crucial for effective treatment. Below is an overview of these processes:
Physiology of Erection
Erections involve a complex interplay of the nervous, vascular, and endocrine systems, as well as the smooth muscles and connective tissues within the penis. The following steps outline the process:
Sexual Arousal: Sensory and mental stimulation activate the parasympathetic nervous system, triggering the release of neurotransmitters like nitric oxide (NO) from nerve endings in the penis.
Vasodilation: NO stimulates cyclic guanosine monophosphate (cGMP) production, relaxing smooth muscle cells in penile arteries and erectile tissue (corpora cavernosa). This relaxation increases blood flow to the penis, filling the corpora cavernosa and compressing veins to trap the blood.
Erection Maintenance: Continuous NO release and smooth muscle relaxation maintain the erection. The pressure from the trapped blood keeps the penis rigid.
Erection Resolution: After ejaculation or cessation of stimulation, the sympathetic nervous system releases norepinephrine, causing smooth muscle contraction. This reduces blood flow to the penis, allowing trapped blood to exit the erectile tissue, returning the penis to a flaccid state.
