I'll preface this by saying I'm not a doctor. However, male hormones (AAS) are administered to transgender women transitioning to male. These drugs will eventually 'masculinize' certain parts of the female body that are irreversible from a hormonal resetting. For example, if the size or shape of the vocal chords have changed from introduction of male hormones, no lack of male hormones or increase in female hormones will restructure the vocal chords.

And to quote the almighty Wiki:

Reversible changes
  • Increased libido
  • Redistribution of body fat
  • Cessation of ovulation and menstruation
  • Increased musculature
  • Increased sweat and changes in body odor
  • Prominence of veins and coarser skin
  • Acne (especially in the first few years of therapy)
  • Alterations in blood lipids (cholesterol and triglycerides)
  • Increased red blood cell count

Irreversible changes
  • Deepening of the voice
  • Growth of facial and body hair
  • Male-pattern baldness (in some individuals)
  • Enlargement of the clitoris
  • Growth spurt and closure of growth plates if given before the end of puberty
  • Breast atrophy – possible shrinking and/or softening of breasts
