After an vaginal ultrasound. I was told I have folliccales on my ovary. Is this of concern?

Not usually a concern at all. In basic terms, the follicles surround an egg and help with preparing the eggs to be released. Prior to ovulation, follicles help in the process of an egg becoming mature. At ovulation, a follicle will rupture to release a mature egg in hopes of becoming fertilized, after which it helps in the early stages of supporting a pregnancy. So it is perfectly normal, and desirable to have follicles on an ovary.

However, sometimes a follicle does not rupture to release an egg and it may become known as an ovarian cyst. This too usually is not a concern and is pretty common, but sometimes can cause discomfort and may need to be treated depending on the cause and type of cyst.
