Confirms ovulation

Whats the accuracy?

A

BBT should begin “Day 1 “ of the cycle in the morning (do not drink or excercise before reading)

The length of cycle tell you when to begin testing

8
Q

What does Home urinary LH kits set out to prove?

accuracy?

A

Predicts ovulation

Accuracy 92%

9
Q

How does Home urinary LH kit work?

A

Measures LH surge ( contains monoclonal antibies that bind to the LH in urine)

10
Q

Which patient population does Home urinary LH kits accuracy decrease for?

PCOS, perimenopause,hyperthyroidism, and endometriosis.

11
Q

Women: Non pharmacological treatment, whats recommend for diet and exercise?

5% decrease in weight may restore ovulation

5% decrease in weight my decrease androgen level in patients with PCOS

Why does Clomiphene have low pregnancy rates when used?

Ovulation - 80%
Pregancy - 40%

A

Ovulation - 80%
Pregnancy - 40%

Low pregnancy rate do to antiestrogenic effects, most preeminent in endometrim (poor curvical mucus)

21
Q

What patients should use insulin sensitizers (metformin)?

A

Patients with PCOS (Polycystic ovary syndrome), Ovulation problems (hormone dysfuntion)

22
Q

Whats the mechanism of action for metformin?

A

decrese hepatic glucose production

Increase menstrual cyclically

decrease andorgen levels

23
Q

whats more effective metformin or Clomiphene?

A

Clomiphene

24

A

yes

A

Cost: cheap

No known effects on the fetus

No need for strict monitoring

Side effects: minimum (GI symptoms)

27
Q

What is the the mechanism of action of Aromatase inhibitors?

A

Aromatase is an enzyme that converts androgens (testosterone and androstendione) to estradiol and estrone.

MOA: reduce estradiol level and therefore increase pituitary gonadroropin output (FSH)
