Definition
Cysts in the ovaries.
Epidemiology
About 1 in 10 women has PCOS! It is the most common cause for infertility in women.
Pathophysiology
The cause is unknown, but it leads to irregular or missed periods, excess androgens and large, cystic ovaries. There is some genetic link, and there is a link with diabetes. Patients with PCOS often have excess insulin in the body.
Risk Factors
Due to the uncertainty of the cause, it is difficult to associate risk factors with this syndrome. Hence, I don't really know what else to write. If anybody does some badass study into it, please feel free to concisely add the findings to this section.
Clinical Features
- Oligomenorrhea, amenorrhea - irregular, few, or absent menstrual periods.
- Infertility - generally resulting from chronic anovulation (lack of ovulation).
- Hirsutism - excessive and increased body hair, typically in a male pattern affecting face, chest and legs.
- Hair loss - appearing as thinning hair on the top of the head
- Acne, oily skin, seborrhea.
- Obesity - one in two women with PCOS are obese.
- Depression.
Investigations
- History taking is a key point - some consider it to be diagnostically conclusive.
- Ultrasound - looking for a characteristic string of pearls appearance.
- Elevated free testosterone levels.
To rule out other conditions
- TSH - hypothyroidism can present in a similar way
- Prolactin - to rule out hyperprolactinemia
Management
Prognosis
Women with PCOS are more at risk of type 2 diabetes, endometrial cancer, hypertension, heart disease and strokes.
