Hyperandrogenism is a state of increased levels of steroid hormones, typically found in males, such as testosterone. This feature is responsible for the Male pattern hair distribution seen in such patients.
Polycystic ovary morphology is a feature seen on ultrasound or any applicable imagine technique.
The cause of this syndrome is unknown. But some factors have been implicated and includes;
• Abnormalities in estrogen and testosterone metabolism
• Hyperinsulinaemia as a result of increased insulin resistance, which causes the ovaries to produce more androgens.
• Abnormal function of the hypothalamic-pituitary-ovarian(HPO)axis.
The HPO axis is responsible for regulating the gonadal hormones, that is, estrogen, estradiol, prolactin and androgens.
