Genital itching can be a symptom of many conditions which may include vaginal infections in females or jock itch in males. In either sex, itching may be caused by skin irritation, sexually transmitted diseases, and allergies.
In many cases, genital itching that is caused by irritation will clear up on its own if the irritation is removed. Other causes of itching may require more intensive treatment. If you are concerned about genital itching that does not go away, talk to your doctor or another health care professional.
