Measure FSH
1) Is it high?

What is Tanner Staging (a sexual maturing rating of secondary sexual characteristics) a reflection of?
True or False: LH, FSH, and Estrogen are low prior to Puberty
True
Three major sites of Estrogen (E2) Biosynthesis?
- Ovary
- Peripheral Tissues
- Estrogen Target Tissues
- Androstenedione–originating from adrenal, ovary, or both–to E1 then to E2
In sexually active females, __ is greater than ___
A. E1>E2
B. E2>E1
B. E2>E1
What are two important enzymes for E2 biosynthesis from androgen precursor?

Four common causes of secondary amenorrhea?
True or False: Low FSH and LH, as well as an estrogen deficiency is associated with Functional Hypothalamic Amenorrhea (secondary amenorrhea)
True
True or False: Normal secondary sexual characteristics are typical in individuals with Functional Hypothalamic Amenorrhea (secondary amenorrhea)
True
How do you restore LH and FSH in Functional Hypothalamic Amenorrhea (secondary amenorrhea)?
Exogenous GnRH
Describe The Female Athlete Triad (Functional Hypothalamic Amenorrhea)
How does the Triad affect:
- GnRH
- LH pulse frequency
- estrogen
- ovulation
- leptin
- ghrelin
True or False: Many CNS substances regulate kisspeptin secretion and hence hypothalamic GnRH secretion.
True
Anterior pituitary gonadotrophs
synthesize and secrete __ and __
FSH/LH
