I would be cautious, there is a big pseudoscience health scam going around convincing people they need to supplement testosterone - targeting both men and women. The current evidence is that there is no known minimum requirement of T in women, so be cautious about claims that women need testosterone supplementation - it's just not evidence based, and there are a lot of quacks trying to sell people on the idea. The article you linked was written by Cate Hall, a CEO of a bio-medical company that manufactures and sells testosterone, there is an obvious conflict of interest here.
Meanwhile we haven't even normalized women taking estrogen supplementation for menopause which does have good evidence is helpful for alleviating the awful symptoms from low E. I have heard so many stories of women having signs of low estrogen being told by their gynecologists they don't need it and they won't even run blood labs to test for low E.
