Terms to know

Cervical Cap
The cervical cap is a form of barrier contraception. A cervical cap fits over the cervix and blocks sperm from entering the uterus.
Contraceptive Diaphragm
The diaphragm is a cervical barrier type of birth control. It is a soft latex or silicone dome with a spring molded into the rim. The spring creates a seal against the walls of the vagina.
Endocervix
The inner part of the cervix that forms a canal that connects the vagina to the uterus. The endocervix is lined with cells that make mucus. During a pelvic exam, cells may be scraped from the endocervix. The cells are checked under a microscope for infection, inflammation, and cancer or changes that may become cancer.
Endometrium
The layer of tissue that lines the uterus.
Fallopian Tubes
A slender tube through which eggs pass from an ovary to the uterus. In the female reproductive tract, there is one ovary and one fallopian tube on each side of the uterus.
Menstrual Cycle
The monthly cycle of hormonal changes from the beginning of one menstrual period to the beginning of the next.
Myometrium
The muscular outer layer of the uterus.
Ovaries
The ovaries are a pair of female reproductive glands in which the ova, or eggs, are formed. The ovaries are located in the pelvis, one on each side of the uterus.
Papanicolaou Test (Pap Smear)
A procedure in which cells are scraped from the cervix for examination under a microscope. It is used to detect cancer and changes that may lead to cancer. A Papanicolaou test can also show conditions, such as infection or inflammation, that are not cancer.
Uterus (Womb)
The small, hollow, pear-shaped organ in a woman's pelvis. This is the organ in which a fetus develops. Also called womb.
Vagina
The muscular canal that goes from the uterus to the outside of the body. During birth, the baby passes through the vagina.
