Disorders of Female and Male Reproductive Tract (Final Exam) Flashcards
this is defined as the absence or suppression of menstruation
amenorrhea
does this describe primary or secondary amenorrhea: no menses for 6 months in a previously menstruating women
secondary amenorrhea
does this describe primary or secondary amenorrhea: failure of onset of menstrual periods by age 16
primary amenorrhea
what are some causes of amenorrhea
- normal physiological process (e.g. athletes, pregnancy)
- disorders of the uterus, ovaries, hypothalamus or pituitary
amenorrhea may be caused by disorders of the ovaries. would the following describe primary or secondary amenorrhea: premature loss of follicles
- genetic
- lymphocytic oophoritis (Autoimmune disease)
- chronic anovulation
- chemo/radiation
primary
amenorrhea may be caused by disorders of the ovaries. would the following describe primary or secondary amenorrhea: decreased gonadotropin stimulation
- hormonal feedback disorders
- pituitary disorders
- hypothalamic disorders
secondary
this is a primary disorder of the ovaries that causes amenorrhea. this is a condition that only affects females, and results when one X chromosome is missing or partially missing. it can cause short height, failure of the ovaries to develop and heart defects.
Turner syndrome
this is a primary disorder of the ovaries that causes amenorrhea. this disease happens when the immune system mistakenly attacks the ovaries causing inflammation, atrophy and fibrosis. elevated FSH and LH plasma levels are seen here
lymphocytic oophoritis
this is a primary disorder of the ovaries that causes amenorrhea. Adequate number of follicles failure to mature and ovulate. there is an increased risk of endometrial cancer here, and this disorder is commonly associated with thyroid disease
chronic anovualtion
chronic anovulation can cause this syndrome, which is characterized by
- obesity
- hyperinsulemia with insulin resistance
- dyslipidemia
- elevated plasma estrogen
- hirsutism
- amenorrhea
polycystic ovary syndrome (PCOS)
how does hyperinsulinemia cause amenorrhea
- increased insulin is released because of insulin resistance
- decreased liver production of steroid hormone binding globulin (SHBG-1) and insulin like growth factor binding protein (IGFNP-1)
- increase free IGF-1 and steroid hormones therefore this is overstimulation of IGF-1 receptors
- increased production of LH and decreases production of FSH
- increased ovarian production of androgens
- = amenorrhea
this is a secondary disorder of the ovaries. may be caused by head trauma (new unsure infertility with amenorrhea). Sheehan syndrome (postpartum hemorrhage resulting in necrosis of the pituitary gland) is related to this secondary disorder.
pituitary disorders
this is a secondary disorder of the ovaries. the arcuate nucleus generates a stimulus for GnRH, which can be affected by
- medications and illicit drugs
- psychological stress
- vigorous exercise
- hyperprolactinemia
- hypothyroidism
hypothalamic disorders
what do these symptoms describe
- delayed puberty (breast development and pubic hair)
- cyclic episodes of pain from obstructive menstruation
- hot flashes
- infertility
- atrophic vaginitis
- osteoporosis
- increased risk for endometrial cancer
amenorrhea
this is slight bleeding from endometrium during ovulations (~ day 14). may be caused by
- uterine malignancy
- endometrial polyps
- estrogen therapy
intermenstrual bleeding
