The membranous sac (amnion) containing amniotic fluid that surrounds the developing baby in the uterus.
Inflammation of the glans (head of the) penis, usually as a result of bacterial, fungal or viral infection. Some forms of balanitis are sexually transmitted, such as herpes, thrush and trichomoniasis. Other causes of balanitis are allergy, chemical or mechanical irritation, and the various dermatitises. Balanitis is more common in uncircumcised males, especially if the foreskin is tight. Symptoms are pain, redness and swelling of the glans, often with discharge of pus. Treatment is by rest, analgesics, bathing to remove discharges, antibiotics if appropriate. Further attacks can mostly be avoided by good hygiene. If the foreskin is difficult to retract because it is too long or too tight, circumcision may be necessary.
