What is ovulatory dysfunction?
Describes a patient who
Is not ovulating (anovulation)
Has infrequent or irregular ovulation (oligoovulation)
What is Adolescent HPO Immaturity?
Cycles vary during first few years after menarche due to irregularities in ovulation
True or false, The older you are when menarche hits, the longer it takes for your cycle to regulate
True. Duration of time it takes to establish regular ovulatory cycles increases with increasing age at time of menarche
If a patient hits menarche at <12 years old, when can they expect their cycle to be ovulatory?
1 year
If a patient hits menarche between 12 and 13 years old, when can they expect their cycle to be ovulatory?
3 years
If a patient hits menarche at >13 years old, when can they expect their cycle to be ovulatory?
4.5 years
In Adolescent HPO Immaturity, what causes estrogen to be sustained in absence of progesterone?
No midcycle LH surge
In Adolescent HPO Immaturity, estrogen secretion being sustained in absence of progesterone leads to what?
Proliferation of the endometrium beyond ability of estrogen to maintain it
In Adolescent HPO Immaturity, what is the result of the uncontrolled proliferation of the endometrium?
Irregular, heavy bleeding occurs when the endometrium becomes unstable and continues until estrogen-induced repair takes place

Endocrine disorder that can cause androgen excess, hirsutism, and infertility
When does PCOS typically begin?
Soon after menarche
True or false, insulin resistance can be an etiology of PCOS?
True.
What is insulin resistance?
Insulin resistance causes cells to become less sensitive to insulin —> the body increases insulin (hyperinsulinemia) to maintain normal blood glucose levels

How is PCOS diagnosed?
2 of 3 features required for diagnosis": Rotterdam Criteria
Oligo-ovulation or anovulation manifested by irregular menstrual cycles (oligomenorrhea or amenorrhea 3+ months without menses)
Biochemical or clinical evidence of hyperandrogenism (hirsutism, alopecia, acne)
Polycystic ovaries on Ultrasound- at least 1 ovary must have >20 follicles/ovary and/ or ovarian volume > 10 mL in either ovary - PCOM (polycystic ovary morphology)

This is “ovulatory PCOS” = hyperandrogenism + PCOM, no oligoanovulation
What doe Phenotype D of PCOS consist of?
This is “non-hyperandrogenic PCOS” = includes oligoanovulation + PCOM , no hyperandrogenism

Acne, hirsutism, androgenic alopecia, acanthosis nigricans
Pelvic exam: ovarian enlargement
True or false, There needs to be 2 polycystic ovaries on ultrasound to confirm PCOS diagnosis.
False. Presence of 1 polycystic ovary is sufficient to provide diagnosis.
What labs should be drawn to rule out other causes of PCOS symptoms?
B-hCG
Prolactin
TSH
17-OHP- to rule out congenital adrenal hyperplasia
FSH and Estradiol
What should be drawn to establish hyperandrogenemia?

Low dose CHCs
True or false, We are concerned about increased risk of endometrial hyperplasia and cancer in every patient with irregular menses.
False, if menstrual bleed occurs at least every 3 months they are having endometrium shedding often enough to prevent increased risk of endometrial hyperplasia or endometrial cancer

What causes hyperprolactinemia?
Anterior pituitary secretes prolactin —> excess prolactin inhibits secretion of GnRH —> production of FSH and LH is affected
What are causes of hyperprolactinemia?
Hypothyroidism; most common cause
Prolactin-secreting pituitary adenomas or other pituitary or hypothalamic tumors
tumors disrupt delivery of dopamine
Breast/chest wall surgery, cervical spine lesions, or herpes zoster
Renal insufficiency and macroprolactinemia due to decreased clearance
What is the relationship between hypothyroidism and hyperprolactinemia?
Decreased levels of T4 —> increased levels of thyrotropin releasing hormone —> increased prolactin secretion
Prolactin suppresses GnRH secretion —> low gonadotropin and estradiol—> amenorrhea
What is a common cause of secondary amenorrhea?
Hyperprolactinemia
Prolactin suppresses which process?
GnRH secretion. This results in low gonadotropin and estradiol and leads to amenorrhea
