Q

What is the MOA of letrozole? (2)

A
  1. An aromatase inhibitor that is used off-label (1st line) to help with anovulation
  2. As aromatase is suppressed, so are estrogen levels, and the hypothalmus & pituitary gland increase FSH output which stimulates ovarian follicles to develop and mature in the ovary so ovulation can occur

Q

Compare efficacy of letrozole and clomiphene

51
Q

Describe basal body temperature (BBT) (4)

A
  1. BBT is the temperature that occurs prior to rising in the am
  2. Progesterone is thermogenic (elevated levels cause an increase in temp). With ovulation, the corpus luteum releases progesterone causing an increase in temperature of approx. 0.5ºF or 0.28ºC.
  3. The rise in temperature is caused by ovulation, therefore measure temp. to find most fertile period
  4. Temperature rise occurs over a period of up to 3 days and is usually maintained until day 1 of menses.
52
Q

What are some counseling tips regarding BBT charting? (4)

A
  1. Take 1st measurement on 1st day of menstrual period.
  2. Take temperature for at least 5 minutes each morning upon awakening, before any activity or getting out of bed.
  3. Record information for 1-3 cycles in order to identify a pattern
  4. Chart temp on graph daily. Indicate on chart when intercourse occurs, illness, changes in sleeping pattern, when meds are taken…
53
Q

How do ovulation prediction kits work?

A

These kits detect the LH surge that precedes ovulation by measuring its concentration in urine

54
Q

How to use an ovulation prediction kit? (2)

A
  1. Chart menstrual cycle ahead of time so that ovulation may be predicted; it also useful to know that the most fertile period is 14 days before the next menses –> hence count backwards
  2. Begin testing 2-4 days before anticipated ovulation at same time of day (usually am)
55
