41
Q

Cycling females may consider collecting in their midluteal phase, between days
___ and ___ of a 28-day cycle, If the cycle is different than 28 days
in length, simply subtract ___-___ from the cycle length. For example: collect on days 17-20 for a 26-day cycle. If there are irregular cycles, consider collecting 5-7 days after ovulation. Ovulation can be determined by following BBT and with an OPK, see Figure 1.11 as well as “Basal Body Temperature (BBT)” and “Ovulation Predictor Kits (OPKs)” below, to learn how to use BBT and OPKs. It may be helpful to collect in the luteal phase to understand if ovulation has occurred, if the corpus luteum is making adequate progesterone, and if estrogen is well balanced with progesterone.

A

19 and 22 , 6-9

42
Q

Preovulatory BBTs range from about ___-___ degrees Fahrenheit. After ovulation, BBT rises to about 97.8 degrees or higher. This is because after a female ovulates, the follicle that released the egg turns into the corpus ____ and begins making progesterone. Progesterone is thermogenic meaning it increases body temperature.

A

97.0 to 97.7 , luteum

43
Q

which pathway is carcinogenic for estrogen

A

4-OH-estrogen

44
Q

studies, which have found that ___-___ mg of oral or 45-90 mg of vaginal progesterone, nightly, protects the endometrium.

A

100-200

45
Q

at the _____ level, whereas the beta androgen metabolites (5b-androstanediol and ______) have little to no androgen activity

A

tissue, etiocholanolone

46
Q

If excessive testosterone replacement therapy (TRT) is used, symptoms of androgen excess (facial hair growth, body hair growth, scalp hair ____, acne, mood changes, etc.) will often manifest.

insulin. anorexia,

53
Q

DHEA converts to DHEA-S with hydroxysteroid sulfotransferase while DHEA-S converts to DHEA with steroid sulfatase; these interconvert in different locations within the body.

DHEA-S may be decreased by: Low cysteine, inflammation, LPS, ketoconazole, ____ licorice.

A

St. John’s Wort, progestin,

54
Q

May be increased by: ______, smoking, PAHs.

May be decreased by: Flavonoids, resveratrol.

A

Inflammation,

55
Q

May be increased by: Cruciferous vegetables, DIM/IC3, ______,____ fish oil, rosemary extract, thyroxine, flaxseed.

May be decreased by: High sugar diet, moderate alcohol consumption, ______, pterostilbene.

A

56
Q

Day one of the menstrual cycle (and day one of the follicular phase)
is marked by the onset of menses. During the follicular phase, follicle stimulating hormone (FSH) stimulates multiple follicles to grow
within the _____. While this is happening, _____ ______ stimulates ovarian theca cells to make androgens and FSH stimulates the aromatase enzyme to convert these androgens to estrogens in the ovarian granulosa cells. A single, dominant follicle is selected around cycle days ___-____ This selected follicle will go on to release an egg later in the cycle. The other follicles that were not selected degenerate.

A

ovary.
luteinizing hormone (LH)
5-7.

57
Q

The follicular phase is followed by the ovulatory phase. During the ovulatory phase, surging estradiol released by the dominant follicle signals the pituitary to release a large amount of LH. About ____-____ hours after LH peaks, ovulation occurs, and an egg is released from the follicle.
The remaining part of the follicle becomes the corpus _____
a temporary endocrine structure that produces progesterone through the end of the menstrual cycle. If pregnancy occurs, the corpus luteum will continue to make progesterone until the placenta takes over at the end of the 1st trimester. If there is no pregnancy, then _____ and _____ levels decrease, triggering menstrual bleeding and starting the next cycle.

A

10-12.
luteum,
estradiol and progesterone

58
