Q

Estrogen dominance can occur when estrogen (E1, E2) and progesterone are within the PMP range, but ___ ___ ___ ____ are above the PMP range

A

phase 1 estrogen metabolites (2-OH, 4-OH and 16-OH phase 1 estrogen metabolites can actively bind to estrogen receptors.)

18
Q

Estrogen dominance may be observed when estrogen replacement therapy (ERT) is used ____ progesterone therapy

A

without (or with inadequate)

19
Q

When a female has a uterus, ERT must be used in combination with progesterone to protect the ______ from hyperplasia and cancer.

A

endometrium

20
Q

The DUTCH Test measures two progesterone metabolites in the urine:____ and _____

A

a-pregnanediol and
b-pregnanediol,

21
Q

a-Pregnanediol modulates ____ receptors in the central nervous system (CNS) and can lead to improvements in ____ and sleep. b-Pregnanediol is the major _____ metabolite, but unlike a-pregnanediol, it does not modulate
GABA receptors.

A

GABA, mood. progesterone

22
Q

In postmenopausal females, progesterone supports ____ , ____, memory, and bone mineral density.

A

sleep, mood,

23
Q

In postmenopausal females, progesterone is predominantly made in the ____ glands.

A

adrenal

24
Q

The progesterone to estrogen ratio can be calculated using b-pregnanediol (the most prominent progesterone metabolite) and E2.

  • Pg/E2 ratio = b-Pregnanediol/E2

The ratio is typically 50-300 in the follicular phase,
<100 during ovulation and
100-500 in the luteal phase.

A

true

25
Q

Low Pg in PMP females who are not prescribed MHT may result in ____ , insomnia, irritability, anxiety, weight ___ and low bone mineral density.

A

26
Q

In PMP females with a uterus who are prescribed MHT, Pg dosing must balance ___ endometrial proliferative effects. When Pg dosing is inadequate, PMP females may be at increased endometrial cancer risk.

27
Q

In PMP females who are not prescribed MHT, HPA axis dysfunction may contribute to ___ Pg levels.
