A normally functioning penis is important for urination, sexual activity, and fertility. Swelling of the penis can interfere with these functions and should be addressed. The size of the penis is impacted by drainage of lymphatic fluid and blood. Swelling may be a sign that drainage of one of these substances is not occurring as it should. The skin of the penis can also become swollen.
Changes in the penis, testicles, scrotum and urinary habits can indicate something is wrong and occasionally that urgent help is needed. However, the majority of penile conditions can be dealt with quickly and painlessly. We speak with a urologist and a sexual health expert about causes, treatments and when it is time to seek medical advice.
Balanitis is irritation of the head of the penis. It is more common in men who have not been circumcised. The area under the foreskin that covers the head of the penis is often warm and moist. This can cause the growth of bacteria or a fungus. This can make the penis sore, red, swollen, and itchy.
