Dear service user Thank you for writing to Healthcaremagic. I understand your concern about erectile dysfunction. Let me tell you that chickenpox does not cause any long term harm like sexual dysfunction or impotency. So, do not worry about it. Ayurvedic medications lack strong scientific research evidence for efficacy in ED. So It may not benefit you. Better to avoid it. An occasional episode of erectile failure due to functional or situational reasons like fatigue, tension or own pressure to perform rather to enjoy is very common. This is common in youngsters. There are other causes of ED like, 1. Diabetes (nerve damage and vessels narrowing) 2. Some medicines like anti depressants and anti psychotics 3. Performance anxiety (the most common reason) 4. Psychiatric disorders (depression, anxiety) 5. Alcohol use (nerve damage and testicular injury) 6. Smoking (vessels narrowing) 7. after some surgical procedures (nerve damage) I recommend you to discuss this problem with your psychiatrist. There are potentially effective medications and behavior therapies for erectile dysfunctions. When persons with similar problem approach at my clinic, I prescribe them Tab. Tadalafil 10 mg to be taken 1 to 2 hours before sex. It usually works. This medicine should be taken under medical supervision otherwise it may be harmful. Wish you good health.
