Origin of the Ferriman Gallwey Score

The original Ferriman Gallwey scoring system, an objective means of assessing the degree of hirsutism at the bedside, was first published by D. Ferriman and Gallwey in an article published in the journal of clinical endocrinology and metabolism in 1961. It can be caused by an underlying medical condition, such as polycystic ovary syndrome (PCOS), or it can be a side effect of certain medications, such as testosterone replacement therapy. Hirsutism can also occur in healthy women with no known cause.

The modified Ferriman Gallway score

The original assessment of hirsutism using the Ferriman-Gallway score assigned a grade ranging from 0 to 4, depending on the presence and extent of terminal hair distribution involving 11 anatomic sites [1]. A score of 0 (no hair growth) to 4 (severe hair growth) at each anatomic site.

To calculate the Ferriman-Gallwey score, simply add up the scores for each of the 9 body areas. It is a quick and easy way to estimate the degree of hirsutism in women. The score ranges from 0-36, with a higher score indicating more severe hirsutism. A total score of 8 or more is generally considered to be indicative of hirsutism.

Modified FG Score:

$$ \text{Ferriman-Gallwey Score} = \sum_{i=1}^{9} S_i $$

Where:

\( S_i \) represents the score for hair growth in each of the following 9 body areas:

  • Upper lip
  • Chin
  • Chest
  • Upper back
  • Lower back
  • Upper abdomen
  • Lower abdomen
  • Upper arms
  • Thighs

The score for each area ranges from 0 (no hair) to 4 (extensive hair).

Total Score: The sum of all \( S_i \) values, ranging from 0 to 36, is the Ferriman-Gallwey Score. A score of 8 or higher suggests hirsutism and may require further evaluation.
