PCOS impacts significantly on various hormonal cycles. With PCOS, luteinizing hormone (LH) levels become higher than follicle stimulating hormone (FSH) levels. Because of this increase in LH levels, the LH surge does not take place and ovulation doesn't carry out which results in irregular menstrual cycle. The irregular menstrual period produces oligomenorrhea (few menstrual periods) or amenorrhea (no menstrual periods) and infertility due to irregular or lack of ovulation. PCOS also produces high levels of masculinizing hormones with symptoms of acne and hirsutism, hypermenorrhea involving heavy and prolonged menstrual periods and androgenic alopecia (increase hair thinning and diffused hair loss). The other metabolic syndromes associated with PCOS are increased risk of type 2 diabetes, high cholesterol levels and obesity.
