Some women experience growth of unwanted chin hair which resembles beards at one point in their lives. A condition known as hirsutism according to healthline.com which is brought about by the production of androgens in high quantities, especially testosterone. This phenomenon is obviously a result of hormonal imbalances that can be brought about by certain health defects which the website explains as:
Polycystic ovarian syndrome
Denoted as PCOS is a disorder that affects women of childbearing age and in menopause. It involves overproduction of male reproductive hormones androgens (which supposed to be released in very minimal quantities) in the ovaries. The resultant physiological changes include irregular menstruation cycles, the growth of beards and other masculine related characteristics.
Cushing syndrome
This disorder leads to unwanted facial hair in women and can be brought about by two things; defect in the pituitary glands and corticosteroid medication. The pituitary glands hosted in the female reproductive system produce ACTH hormones and are responsible for the production of cortisol by adrenal glands. A problem with the glands can, therefore, lead to overproduction of ACTH and cortisol and hence the facial hair. Corticosteroid medication famous for treating asthma and arthritis often results in feminine beards because of all the cortisol produced.
Congenital adrenal hyperplasia
Though rare this condition can lead to the growth of hair in women’s chins. It is caused by failure of adrenal glands to provide sufficient cortisol causing strong male characteristics. It is estimated to be affecting at least 15000 worldwide.
