A

GIFT

17
Q

During the first trimester, the serum quantitative human chorionic gonadotropin hormone levels…

A

Double every 48 hours.

18
Q

What hormone causes ovulation ?

A

Luteinizing hormone

19
Q

What phase of the uterus corresponds to the lateral phase of the ovaries?

A

Secretory phase.

20
Q

What imaging tool should be used in order to quickly assess placement of an IUD that has migrated? (IUD has metal component)

A

X-ray.

21
Q

What helps aid in the union of the sperm and the ovum?

A

Rhythmic contractions of the fallopian tube, the flagella of sperm, and myometrial contraction

22
Q

When may a patient experience ovarian hyper stimulation syndrome?

A

after ART

23
Q

What is something that would lead to a subnormal rise in hCG?

A

Ectopic pregnancy.

24
Q

When does Implantation happen?

A

21 days from LMP

(Note: NOT “21 days after ovulation”)

25
Q

What three things occur with hormonal contraception techniques?

A

-There are changes in the endometrial lining
-Ovulation is inhibited
-Cervical mucous thickens

(Note: NOT “the endometrium remains in the secretory phase”)

26
Q

True/False:

Ovulation and corpus luteum formation can still occur when using inert intrauterine contraceptive devices?

A

True

27
Q

When is the greatest risk for IUD perforation?

A

Upon insertion.

28
Q

True/False:

When follicles are aspirated in preparation for artificial reproduction techniques the needle punctures through the vaginal wall to reach each one of the ovaries.

A

True

29
Q

(Written)

Describe sequential hormone replacement therapy (hormone(s), effects, how/when its taken)

A

For the entirety of a patients cycle while doing sequential HRT, estrogen is taken and the endometrium is at its thickest; then, during the last half of their cycle, they are given progesterone and the endometrium thins. This combination will cause a withdrawal bleeding that resembles a period.

30
Q

Name two IUDs that are no longer in the United States

A

Copper 7
SafeTCoil

31
Q

Name two imaging techniques used to evaluate tubal patency.

A

Sonohystography

Salpingiography

32
Q

Two IUD’s that ARE available in the USA:

A

Paraguard
