Q

List the 9 steps that will describe the hormone changes in the Menstrual Cycle.

A
  1. Corpus Luteum dies, Estrogen and Progesterone levels FALL
  2. Pituitary responds to Fallin E and P by INCREASING FSH secretion
  3. FSH recruits large antral (Follicles secrete LOW amounts of ESTROGEN and INHIBIN B)
  4. E and INHIBIN B negatively feed back on FSH
  5. Declining FSH will cause Follicular Atresia except for DOMINANT follicle (Produces HIGH levels of ESTROGEN)
  6. High E has positive feedback on the gonadotropes LH (and some FSH) SURGES
  7. LH surge induces meiosis maturation, ovulation, and luteinization. The Corpus Luteum Produces HIGH P, E, and INHIBIN A
  8. HIGH P, E, and INHIBIN will NEGATIVELY feed back on LH and FSH, returning them to basal levels
  9. Corpus Luteum progressively becomes less sensitive to basal LH and will DIE if levels of LH-LIKE activity (hCG) does not increase!

Q

What happens when a female keeps having miscarriages around the 10th week?

A

LOW Progesterone! Normally the placenta is going to take over the production of Progesterone but there may be a problem there.

Q

List the changes that occur when you are in the Secretory Phase within the endometrium.

A

A

Anemia

23
Q

Define Polymenorrhea.

A
  • TOO many cycles

- < 21 days per cycle

24
Q

Define Oligomenorrhea.

A
  • NOT ENOUGH cycles

- > 35 day cycles

25
Q

Define Menorrhagia.

A

Excessive and/or prolonged menses (> 80 cc and > 7 days) occuring at REGULAR intervals

26
Q

A

IRREGULAR episodes of Uterine Bleeding

27
Q

Define Menometrorrhagia.

A

HEAVY and IRREGULAR Uterine Bleeding

28
Q

Define Intermenstrual Bleeding.

A

SCANT bleeding at OVULATION

29
Q

Define Dysfunctional Uterine Bleeding (DUB). What is the usual cause? When is this usually going to occur?

A
  • Abnormal Uterine bleeding that cannot be attributed to: Medications, Systemic Disease, Trauma, etc.
  • Cause is changes in the H-P-O Axis
  • Most DUB occurs around the years of menarche (11-14 years) or perimenopause (45-50 years)
30
Q

Explain the PALM-COEIN pneumonic for Abnormal Uterine Bleeding (AUB).

A

Structural Causes: Polyp, Adenomyosis, Leiomyoma, Malignanacy & Hyperplasia

Non Structural Causes: Coagulatory, Ovulatory Dysfunction, Endometrial, Iatrogenic, and Not yet classified

31
Q

Which tool would you use to visualize a Polyp in the Uterus?

A

Hysteroscope

32
Q

Define Adenomyosis.

A

Enlargement of the Uterus due to HYPERPLASTIC nodule in the myometrium

Q

What are the three most common places for Leiomyoma in the myometrium of the Uterus?
