Syphilis Symptoms in Women

Generally, the symptoms of syphilis in women and men are similar according to the stage of the disease. In women, symptoms may include sores on the genitals, lips, cervix, or vaginal walls.

Syphilis Symptoms in Men

Symptoms in men are similar to those in women and may appear on the penis, around the scrotum, anus, groin area, and also inside the urethra.

A painless red bump with raised edges

Syphilis symptoms usually start with a sore at the site where the bacteria entered the body. The sore begins as a painless red bump that gradually enlarges, becomes firm to the touch, with raised edges, and its surface is covered with dried blood and lymph fluid.

In men, this type of sore commonly appears on the foreskin of the penis. In women, the sore is usually smaller and may show no symptoms. There may also be swollen lymph nodes in the groin area during the first stage of syphilis.

Rash all over the body, palms, and soles

There may be a rash covering the entire body, including the palms and soles. The rash is not painful or itchy and occurs during the secondary stage of syphilis.

Mouth ulcers – symptoms of syphilis

Ulcers in the mouth or on the tongue, along with rashes inside the mouth, can result from oral sex with an infected partner. These cause small sores on the tongue but usually do not cause pain. They typically appear between 10 days to 3 months after infection.

Syphilis sores around the anus

Syphilis symptoms around the anus can occur in both women and men who have sex with men. This happens through sexual contact involving the genital area and the skin around the anus. Typically, syphilis sores are firm, red or dark-colored bumps that usually don’t hurt much. However, sores around the anus can cause irritation or discomfort during bowel movements.

If the examining doctor is not experienced, these sores are often mistaken for hemorrhoids because firm lumps can be felt. A definitive diagnosis relies on blood tests for syphilis.
