Lesson 2B Flashcards
What are the 4 stages for the endometrium?
- Early proliferative phase
- Late proliferative phase
- Secretory phase
- Menses
When does the early proliferative phase start?
Right after menses
- getting ready for another cycle
Why is the endometrium so thin during the early proliferative phase?
Because the layer was just shed and it needs time to get thick again
What days do early proliferative phase occur?
Days 5-6
What days is the later proliferative phase?
Days 8/9-13
What kind of appearance occurs during the late proliferative phase?
Triple line appearance
What day does ovulation occur?
Day 14
What days does the secretory phase occur?
Days 15-28
What hormone is more common in the secretory phase?
Progesterone
What is the echogenicity during the secretory phase?
Hyperechoic
What days does menses occur?
Days 1-5
What occurs during menses?
The functional layer of the endometrial is being shed
- if not pregnant
What is the size range of normal ovaries at the reproductive age?
6cc-18cc
- after 10cc they are considered to be a problem
- smaller in young and postmenopausal women
What is the normal measurement range of the dominant follicle?
2-2.5cm
What is the shape of normal ovaries?
Oval shaped
- some are more circular
- some are more elongated
How are normal ovaries seen sonographically?
Anechoic follicles are seen
- around the ovary
What does the follicular and luteal phase correspond to?
The change of the endometrium
What is a landmark for the ovaries?
The uterus
- can tell whether it is a left or right ovary
What are the 3 stages of egg depletion from the ovary?
- Reproductive age
- Just before menopause
- Menopause
What happens in terms of egg depletion from the ovary during reproductive age?
The ovary is full with eggs at different stages and is producing eggs
What happens in terms of egg depletion from the ovary just before menopause?
The ovary has less eggs than before and is producing less estrogen
What happens in terms of egg depletion from the ovary during menopause?
The ovary has no eggs and is not producing any estrogen
Where is it normal to see a bit of fluid after the late proliferative phase?
In the posterior cul-de-sac
What volume is considered abnormal for a postmenopausal ovary?
If it is greater than 8cc
