Yes, weight loss can help reduce androgen levels in women with PCOS. Since overweight or obese women with PCOS are more likely to have insulin resistance, losing even a small amount of weight (5-10% of body weight) can improve insulin sensitivity, reduce androgen levels, and help manage hirsutism.

Excess facial hair is a symptom of hormonal imbalances in PCOS, but it does not directly affect fertility. However, the underlying cause of the hair growth, such as elevated androgen levels, can also impact ovulation, making it more difficult to conceive. 

Yes, abnormal facial hair is often accompanied by other symptoms of PCOS, including:

• Irregular periods or absence of periods
• Acne or oily skin
• Thinning hair on the scalp
• Weight gain or difficulty losing weight
• Infertility or difficulty conceiving
• Darkening of the skin (acanthosis nigricans), often around the neck or underarms
• Mood swings or anxiety related to hormonal fluctuations

Managing the underlying hormonal imbalance and insulin resistance can help address these symptoms simultaneously.

You should consult a doctor if:

• Your facial hair growth is becoming more severe or affecting your quality of life.
• You are experiencing other symptoms of PCOS, such as weight gain, acne, or irregular periods.
• You are having difficulty managing your symptoms with over-the-counter treatments or lifestyle changes.
• You want to explore medical options like birth control, anti-androgen medications, or laser hair removal.
