Menopause Definitions
The Menopause Society has compiled a comprehensive list of definitions for terminology related to menopause, perimenopause, and other terms relating to midlife women’s health issues.
A
Abdomen. The part of the body below the ribs and above the pelvis.
Abnormal uterine bleeding (AUB). Bleeding that is abnormal in frequency, severity, or duration. Different from normal irregular periods during perimenopause or bleeding from hormone therapy including estrogen and progestogen.
Amenorrhea. The absence of a woman’s monthly period not related to menopause.
Anal incontinence. Loss of anal sphincter control leading to involuntary leakage of gas or solid or liquid stool sufficient to impair quality of life.
Androgenetic alopecia. Thinning of the hair on the scalp in midlife women.
Androgens. A group of hormones that promote the development and maintenance of male secondary sex characteristics and structures. They are produced in smaller quantities in women and are important in the synthesis of estrogen. They also play a role in sexual function, muscle mass and strength, bone density, distribution of fat tissue, energy, and psychological well-being.
Antidepressants. Prescription therapy government approved to treat depression and anxiety.
Antihypertensives. Prescription therapy government approved to treat high blood pressure.
Anti-inflammatory drug. A type of prescription and nonprescription therapy used to relieve inflammation, swelling, stiffness, and joint pain.

Anxiety. A feeling of apprehension, fear, nervousness, or dread accompanied by restlessness or tension.
Aromatase inhibitors. A class of prescription drugs government approved for the prevention and treatment of breast cancer.
Arthritis. A disease of inflammation in the joints that may be associated with pain, stiffness, swelling, and redness as well as deformities of those affected joints.

They are active in many cells throughout the body by interacting with estrogen receptors. Several types of estrogen therapies are available for menopause indications.
Estrogen patch. Also estrogen skin patch or estrogen transdermal delivery system. A form of estrogen therapy contained in a special patch that is adhered to the skin. The patch technology allows a gradual release of estrogen through the skin directly into the bloodstream, where it circulates throughout the entire body (systemically), affecting many different tissues.

Specifically, a sex hormone (such as estrogen, progesterone, testosterone) produced by the ovaries (in women), testes (in men), or adrenal gland (in both women and men) that affects the growth or function of the reproductive organs or the development of secondary sex characteristics. Also includes non-sex hormones such as thyroid hormone.
Hormone therapy (HT). Prescription drugs used most often when treating menopause symptoms.
Hot flash. A condition resulting in a red, flushed face and neck, perspiration, an increased pulse rate, and a rapid heartbeat, often followed by a cold chill.

Menorrhagia. Increased menstrual bleeding occurring at regular intervals or bleeding that last more than 7 days.
Menses. The menstrual period.
Menstrual cycle. The time each month (typically every 4 weeks) when an egg develops in the ovary, the lining of the uterus thickens, and the egg is released into the uterus. If the egg is not fertilized by sperm, the lining of the uterus (with the egg tissue) is shed through menstruation and the cycle begins again. This cycle typically becomes irregular during perimenopause and ends completely at menopause.
Menstruation. A woman’s “period”—the discharge of blood, secretions, and tissue debris from the uterus that recurs in nonpregnant women.

Oophorectomy. Surgical removal of an ovary.
Orgasm. Sexual climax.
Osteoarthritis (OA). The most common form of joint disease. Increases in frequency with the “wear and tear” of aging and particularly affects aging women.
Osteoporosis. Postmenopausal osteoporosis is a disease of older women in which the bone density of the skeleton has decreased to a point where bone has become fragile and at higher risk for fractures, often with little or no trauma. In most women, bone loss accelerates during the first few years after menopause, which is related to the decline in estrogen levels.

Ovarian cyst. A sac filled with fluid or a semisolid material that forms on or within one of the ovaries, usually noncancerous.

A span of time that begins with the onset of menstrual cycle changes and other menopause-related symptoms and extends through menopause (the last menstrual period) to 1 year after menopause. Perimenopause is experienced only with spontaneous (natural) menopause, not induced menopause. Also called the menopause transition. See also Induced menopause.

Premenopause. The span of time from puberty (onset of menstrual periods) to perimenopause.
Primary ovarian insufficiency (POI). A condition that occurs at an earlier age than 40 in which many periods in a row are skipped or there are no periods at all, which can be a sign of menopause or of very few eggs left in the ovaries. POI differs from premature menopause in that ovarian activity may resume.
Progesterone. A female hormone that is released by the ovaries after ovulation to prepare the lining of the uterus (endometrium) to receive and sustain the fertilized egg and thus permit pregnancy. If pregnancy does not occur, progesterone (and estrogen) levels fall, resulting in menstruation. Available in prescription and nonprescription therapies (as a bioidentical hormone).
Progestin. A class of progestogen compounds synthesized to act like progesterone in the body. Available in oral prescription drugs and combined with estrogen in prescription skin patches.

T
T-score, Z-score. Values that report the results of evaluating bone strength and predicting fracture risk. The Z-score compares the bone density to similar-age women and is a rough index of the need for extra diagnostic studies, whereas the T-score compares bone density to young women and is a rough index of the need for treatment.
Testosterone. The male androgen hormone that is essential for sperm production and responsible for inducing and maintaining male secondary sex characteristics. In women, testosterone (partially produced by the ovaries) may regulate sexual desire and may also help maintain bone and muscle health.

Vaginal atrophy. A condition in which estrogen loss causes tissues of the vulva (the external parts of the female genital organs) and the lining of the vagina to become thin, dry, and less elastic. Vaginal secretions diminish, resulting in decreased lubrication.
Vaginal dryness. Inadequate lubrication of the vagina that can be caused by low estrogen levels, medication, or lack of sexual arousal.
Vaginal estrogen. Prescription estrogen therapy that is applied vaginally (as cream, ring, suppository, or tablet) and is government approved to treat moderate to severe vaginal dryness and atrophy. Most vaginal estrogen therapies provide local, not systemic, treatment.
Vaginal lubricant. Nonprescription, water-based products that are applied to the vagina to decrease friction and reduce discomfort during intercourse.
