PCOS, Endometriosis, & Abnormal Growths Flashcards

About X% of normally ovulating women experience polycystic ovaries but do not experience other criteria surrounding a PCOS diagnosis.
25%
True or False: Polycystic Ovary Syndrome is characterized by a certain set of conditions rather than one standalone diagnostic parameter such as polycystic ovaries.
True
Why can’t PCOS be diagnosed through ultrasound alone?
We now understand is that this syndrome is way more complex, and is characterized by a certain set of conditions, rather than one standalone diagnostic parameter such as polycystic ovaries. It is said that about 25% of normally ovulating women experience polycystic ovaries but do not experience other criteria surrounding a PCOS diagnosis
There has been recent conversation of if Polycystic Ovary Syndrome is an accurate name for this condition, and if it should be renamed as BLANK, as not all cases have polycystic ovaries.
Metabolic Reproductive Syndrome
In order to diagnose PCOS properly, according to the Androgen Excess & PCOS Society Criteria, a woman must experience which 3 of the following biomarkers?
- Irregular cycle OR polycystic ovaries
- High androgens or symptoms of high androgens
- Ruled out other conditions that could potentially cuase hyperandrogenism
This criteria for diagnosing PCOS is perhaps more accurate than other forms but is met with high controversy in varying medical communities.
What is hyperandrogenism?
High androgens
Androgens like testosterone are sex hormones.
What are symptoms of high androgens?
- Deepening or hoarsening voice, acne, especially along the chin-line
- Hirsutism, which is characterized as male-patterned hair loss or hair thinning, facial, nipple, or other body hair growth.
What are other conditions that could potentially cuase hyperandrogenism?
- Congenital adrenal hyperplasia
- Cushing’s disease
- Ovarian or adrenal tumors
- Certain medications, such as progestin-only birth control with a high androgen index
What is the Rotterdam criteria?
Was formed to diagnose PCOS as an alternative criteria option with less rigorous parameters.
Although potentially less accurate, it is more commonly used to refer to and diagnose PCOS.
According to the Rotterdam criteria, a woman must have 2 of the 3 following biomarkers to get diagnosed with PCOS?
- Polycystic ovaries on ultrasound
- Irregular cycles
- High androgens or symptoms of high androgens (as well as ruling out other conditions associated with hyperandrogenism)
This means that a woman could technically be diagnosed with PCOS if she shows having polycystic ovaries and irregular cycles, but not hyperandrogenism, which is considered amongst many as a main characteristic of PCOS, as it tends to be the driving factor behind ovarian suppression leading to the other symptoms
What is the issue with the Rotterdam Criteria?
A woman could technically be diagnosed with PCOS if she shows having polycystic ovaries and irregular cycles, but not hyperandrogenism, which is considered amongst many as a main characteristic of PCOS, as it tends to be the driving factor behind ovarian suppression leading to the other symptoms.
What are some of the reasons that could cause a woman to experience anovulation and irregular cycles that aren’t specifically related to high androgens?
- Physical & psychological stress
- Elevated prolactin
- Exposure to endocrine-disrupting chemicals
- Decreased FSH
- Perimenopause
- Any other condition that would suppress or interfere with hypothalamic & pituitary hormone output
Prolactin is a hormone that’s responsibel for lactation, certain breast tissue development and milk production.
What are Polycystic Ovaries defined as and why?
12 or more pre-antral follicles measuring 2–9 mm and/or an increased ovarian volume.
Because in a normal ovulating woman, it is common for up to 12 pre-antral follicles to develop per ovulatory cycle, of which only one is chosen to become the primary antral follicle that will go on to ovulate an egg. The rest are merely suppressed and may resemble small cysts during the follicular phase until they are reabsorbed by the ovaries
Teenage girls may exhibit up to BLANK pre-antral follicles per ovulatory cycle, so the definition of polycystic ovaries may vary upon age.

Should a doctor diagnose a teenage girl with PCOS?
Only time can tell for these young women if they do indeed have PCOS or not, as their pre-antral follicle count may eventually lower to average levels, and their body may become accustomed to their hormonal cycles, leading to more regular ovulatory cycles.
Despite all the varying diagnostic criteria, there is a general consensus that PCOS is characterized by BLANK and BLANK
ovulatory failure and high levels of androgens
Although this may seem simple, we have to consider that there are varying driving factors that contribute to these situations, which may be different for each individual.
For many, PCOS tends to be a low-BLANK stage, which goes against the common belief that excess estrogen can drive PCOS symptom. Why is this?
Estrogenic
Often the result of improper aromatization due to leptin resistance and abnormalities in the follicular granulosa cells, which can be partial to blame for both hyperandrogenism and anovulation in women with PCOS.
Because women with PCOS do not ovulate regularly, they tend to experience BLANK dominance by ratio, potentially contributing to symptoms such as PMS and heavy periods.
Estrogen
Roughly 70% of women with PCOS have been shown to have decreased BLANK sensitivity, suggesting that BLANK may be an extremely common factor behind many PCOS cases
Insulin; insulin resistance
Interestingly, there may also be a connection between BLANK downregulation in women with PCOS, further contributing to dysregulated blood sugar and insulin resistance.
GLUT4
Why do we refer to Insulin resistance-driven PCOS as Ovarian PCOS?
Because high insulin levels can increase LH production, causing the ovaries to produce more androgens and less estrogen.
Lutenizing Hormone, spurs ovulation and helps with the hormone production needed to support pregnancy.
What may account for the abnormal elevation in LH in women with PCOS?
Altered GnRH pulsation, as well as lowered Inhibin B,
Gonadotropin-releasing hormone is a releasing hormone responsible for the release of follicle-stimulating hormone and luteinizing hormone from the anterior pituitary
What is a common pattern we see in PCOS?
A higher LH to FSH ratio (high LH, low FSH), typically a ratio of 3:1
High insulin can contribute to increased BLANK and BLANK.
