Hello Anon

Thank you for writing.

There is no difference between the bodies of married women or single women. There are many virgins who are not married but many women are single and not virgins. There are even virgin married women!

Follicles grow in the ovaries each month. They make hormones and release an egg during ovulation. In some cases, follicles may become cysts. There are two main types:

Functional cyst—occurs when a normal monthly follicle does not mature properly and the egg is not released
These cysts go away on their own within 1-3 menstrual cycles.
Follicular cyst—occurs after an egg is released
These cysts go away on their own in a few weeks.

These are a type of functional cyst.
Most are functional cysts. They only occur during childbearing years. Many other, less common types of benign cysts can also form from ovarian tissue. For example, if you have endometriosis , you may form cysts from the uterine tissue on an ovary.

Polycystic ovary syndrome is also linked to cysts. This happens when several small cysts (more than 10) grow in the ovaries.

In a small percentage of cases, cysts are caused by cancer .

Another condition linked to cysts is ectopic pregnancy . Your doctor will do a pregnancy test to rule this out.

Risk Factors
The main risk factor is being a woman of childbearing age, about ages 16-45.

Endometriosis - as talked about above - is often caused by a sexually transmitted disease. But many cysts have nothing to do with sex at all and have nothing to do with endometriosis. If you do not have a sexually transmitted infection (such as chlamydia or gonorrhea) then the fact that you are not a virgin is not important.

However, make sure you ALWAYS use condoms when you have sex - no exceptions.

It seems to me that your doctor is judging your negatively for having sex outside of marriage and blaming you for the cyst. My advice is to choose a less judgmental and more educated/enlightened doctor.

Best,
