The progesterone is an attempt to slough the lining, not increase it. This is a common problem with the onset of menopause, as the balance between estrogen and progesterone starts to shift. Most women will experience this problem in the transition to menopause. My friend has venereal warts, but she will not go to a gynecologist to have them treated. She is not sexually active.
Venereal warts are due to a virus.
This is usually human papillomaviruses. Some of the sub-groups increase the risk of cervical and penile cancer and some advocate typing the virus as well as treatment. They will not lead to blindness or systemic disease other than the risk of cancer locally, which is a long term risk. There is no perfect way to eliminate the virus. Cryotherapy and different local chemical preparations are used with long term surveillance to ensure that early lesions are detected and treated.
