Is this true? I have never heard of that before.
Most cells have similar numbers of mitochondra, regardless of sex. There may be modest groupwise differences between sexes in muscles, based on strength and fitness, but this has little to do with succeptibility to ME/CFS or Longcovid.
The number of mitochondria in major muscle groups is always in excess to what is required to achieve VO2Max anyway, including in CFS patients. (VO2Max is limited by the cardiovascular system - the heart/vascular system for most people, and the lungs in COPD patients and elite athletes with a very high level of training)
