    Study Notes

    PCOS Overview

    • PCOS (Polycystic Ovary Syndrome) is a significant public health concern impacting reproductive, metabolic, and psychological well-being.
    • It's one of the most common conditions in reproductive-aged women, affecting 8-13% of this group with a higher prevalence in specific ethnicities.
    • A significant proportion (up to 70%) of affected women remain undiagnosed.

    Rotterdam Criteria

    • Two of the following three criteria are necessary for diagnosis:
      • Oligo/anovulation (irregular or absent menstruation)
      • Hyperandrogenism (either clinical, such as hirsutism or male-pattern baldness, or biochemical, meaning elevated levels of androgens)
      • Polycystic ovaries (identified on ultrasound)
    • Other conditions (such as congenital adrenal hyperplasia, androgen-secreting tumors, Cushing's syndrome, thyroid dysfunction, and hyperprolactinemia) need to be ruled out.

    PCOS Presentation

    • Key symptoms include :
      • Hirsutism and male-pattern balding
      • Acne
      • Irregular or absent menstrual cycles
      • Subfertility or infertility
      • Psychological symptoms (anxiety, depression, psychosexual dysfunction, eating disorders)
      • Metabolic features (obesity, dyslipidaemia, diabetes)

    PCOS Phenotypes

    • The NIH 2012 workshop categorized PCOS into phenotypes:
      • Phenotype A: Androgen excess + ovulatory dysfunction + polycystic ovarian morphology
      • Phenotype B: Androgen excess + ovulatory dysfunction
      • Phenotype C: Androgen excess + polycystic ovarian morphology
      • Phenotype D: Ovulatory dysfunction + polycystic ovarian morphology

    Oligo/anovulation

    • Irregular menstrual cycles are defined differently based on whether it's before or after reaching puberty:
    • Primary amenorrhea: No periods by the age of 15 or more than 3 years post-breast development (thelarche)
    • Secondary amenorrhea: Absence of menstruation for more than 3 or 90 days after reaching puberty.
    • Cycles of longer than 21 days or shorter than 45 days in the first year post-menarche (initial menstruation) are considered normal

    Hyperandrogenism

    • This is characterized by raised androgen levels, evidenced by symptoms like:
      • Hirsutism (excessive hair growth). Clinicians should recognise that many women treat the condition, so are not always reliable symptoms.
      • Acne
      • Male pattern alopecia (hair thinning/loss)
      • Biochemical hyperandrogenism (elevated androgen levels in the blood)

    Ovarian Morphology

    • Polycystic ovaries on ultrasound are diagnosed if 12 or more small antral follicles (fluid-filled sacs) are present per ovary, each measuring 2 to 9 mm in diameter, or if the ovarian volume exceeds 10 mL.
    • Ultrasound findings are not always reliable in adolescents and young women, and should not be used to diagnose PCOS within 8 years of menarche.

    PCOS Management

    • Management involves:
      • Lifestyle modification (healthy diet, weight loss, exercise): This can help restore menstrual regularity, control metabolic risk factors, and improve psychological well-being.
      • Medical treatment: This encompasses various options, such as combined oral contraceptives (COCPs) for irregular cycles, medications targeting hyperandrogenism, and other treatments for complications like diabetes and cardiovascular disease.
      • Surgical treatment (ovarian drilling): This is an option in some cases for improving ovulation.

    Subfertility

    • PCOS is a common reason for issues with fertility
    • Lifestyle modification (especially weight loss) is usually the first step in managing subfertility.
    • Women under 35 with an elevated BMI may benefit from focusing initially on a lifestyle program to address weight concerns to restore fertility.
    • If lifestyle changes don't improve fertility, a specialist should be consulted for possible further treatment.

    Ovulation Induction

    • First-line treatment for ovulation induction (in PCOS related infertility) is Letrozole.
    • Clomiphene citrate is the second line, followed by gonadotrophins.
    • More aggressive treatments like IVF/ICSI might be considered if the above options are insufficient

    Cardiovascular Risk Modification

    • Women with PCOS have an increased risk of cardiovascular disease, so proactive monitoring and management are crucial.
    • This includes assessing cigarette smoking, measuring weight regularly, monitoring blood pressure and glucose tolerance annually, and conducting lipid profiles in intervals as dictated by risk factors.

    Metformin

    • Metformin can be beneficial in cases of insulin resistance.
    • It may be used alongside lifestyle modification for managing hormonal and metabolic aspects of PCOS.
    • It might be used in combination with COCPs for cycle regulation.
