Overview

Presented case reports illustrate clinical manifestations of two women with polycystic ovary syndrome who had extremly low serum SHBG levels (Sex Hormone Binding Globulin) due to homozygote carriership of the rare Pro156Leu SHBG polymorphism.

Key words:
SHBG –  polymorphism –  polycystic ovary syndrome
