Amenorrhea Danielle, Kelsey, Joe, Matt Table 3 Period 3
An Overview
An Overview Amenorrhea is defined as the absence of menstrual bleeding and may be primary or secondary.
An Overview Primary Amenorrhea is the absence of menstrual bleeding and secondary sexual characteristics in a girl by age 14. -OR- The absence of menstrual bleeding with normal development of secondary sexual characteristics in a girl by age 16.
An overview For a woman to have a regular menstrual cycle, her HYPOTHALAMUS, PITUITARY gland, OVARIES and UTERUS should all be functioning normally.
An overview The Hypothalamus stimulates the pituitary gland by releasing follicle stimulating hormones (FSH) and luteinizing hormone (LH). This causes the ovaries to produce the hormones estrogen and progesterone.
An overview Estrogen and progesterone are responsible for the cyclical changes in the endometrium ( uterine lining), including menstruation.

Causes
Hypothalamic causes Craniopharyngioma - a brain tumor near the pituitary gland. Teratoma -a tumor made up of a mixture of tissues. Sarcoidosis - the formation of nodules in different parts of the body.
Hypothalamic causes Kallmann Syndrome- Deficiency of gonadotropins, which are hormones capable of promoting growth and function of reproductive hormones. Nutritional Deficiency Low Body Weight
Pituitary Causes Prolactinemia - High blood levels of prolactin, a hormone that stimulate the secretion of breast milk. Pituitary Tumors Postpartum Pituitary Necrosis- Death of pituitary cells after a woman delivers a baby.
Pituitary causes Autoimmune Hypophysitis - Cells of the pituitary gland destroyed by the body’s own defense system Pituitary Radiation
Ovarian Causes Anovulation- Lack of the release of an egg Hyperandrogenemia - High blood levels of male hormones Polycystic ovary syndrome Premature Ovarian Failure Turner Syndrome-Genetic disorder characterized by underdeveloped ovaries, short stature.
Ovarian Causes Pure Gonadal Dysgenesis - Defective development of the ovary Autoimune O ophoritis - Cells of the ovaries destroyed by the body’s own defense system Radiation or Chemotherapy Abnormalities of the genital tract
