What are the most common STD symptoms reported for men?

The most common STD symptoms in men are painful urination, swollen testicles, genital warts and penile discharge caused by chlamydia, gonorrhea and human papillomavirus, states Healthline. The symptoms of other common STDs, such as hepatitis B, herpes simplex and syphilis, include jaundice, swollen lymph nodes, and genital blisters and sores.

Some of the STDs sometimes show no symptoms, such as HPV, or their symptoms are mistaken for other diseases, such as hepatitis B mistaken for the common cold. Despite this, most of them are curable, and all are treatable, states WebMD. Treatment involves antibiotics for bacterial STDs, such as syphilis, and medication to manage viral STDs, such as herpes.
