Trans man (Or FtM/MtM) is a term which describes someone who is both a man and transgender/transsexual. Trans men were assigned female at birth, but their gender identity is male. They may be referred to as transmasculine. Some trans men wish to transition in order to change their sex characteristics and gender expression to become more masculine. Trans men can have any sexual orientation.


A flat chest can be achieved in many ways. There are commercially-made specialty binders available worldwide which are safe and effective for the compression of breast tissue and allow for normal breathing in most people.

Other methods of binding include compression bandages, back braces, tape, modified clothing, very firm sports bras and tight-fitting shirts. These methods are more popular with young people who have not yet come out as trans, or those who have limited financial means.

Dangerous binding methods

Binding with tape or elastic/compression bandages can cause serious injury and even death due to asphyxia. If applied incorrectly, they can compress the rib cage so greatly as to make normal breathing impossible.Tape is also ill-advised due to potentially permanent damage to the skin caused by adhesives, and due to the inflexibility of materials that puts the wearer at a similar risk as bandages

Hormone Replacement Therapy

see also Hormone Replacement Therapy

Allows the patient to "pass" or be seen as the gender they identify with. Introducing synthetic hormones into the body impacts it at every level and many patients report changes in energy levels, mood, and appetite. The goal is to provide patients with a more satisfying body that is more congruent with their true psychological gender identity.

Changes with HRT

  • Increase in muscle and decrease in body fat
  • Development of facial and body hair
  • Deepening of the voice
  • Male pattern baldness and receding hairline (for some people)

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 and possible shrinking and/or softening of breasts.

Reversible changes

Increased libido, redistribution of body fat, ovulation and menstruation, further muscle development, increased sweat and changes in body odor, prominence of veins and coarser skin, acne, alterations in blood lipids,  and increased red blood cell count.

Common Surgery Options:

Chest Surgery:

Double Incision Method:

Can be performed on transmasculine patients with sagging breasts. This usually requires a scar extending from underneath the existing breast fold to the lateral outside of the chest. The nipple and areola are removed, resized, and replaced as a “free nipple grafts” in a new position to give a “male” appearance to the chest. The scars are permanent, but most scars will fade and many patients are very happy with their new chest appearance.

Peri-areolar or Keyhole Method:

For transmasculine patients with small breasts who have little breast tissue, breast skin that does not sag, or breast skin that is too tight to perform a double incision method. Bottom Surgery: Metoidioplasty:

The removal of the ligaments surrounding a testosterone-enlarged phallus/clitoris, allowing it to protrude further from the body.

Bottom surgery:


Construction of a penis from tissue harvested from either the forearm, the side of the chest, the pubic area, or the thigh. Some bottom surgeries would give the persons ability to let them peeing standing up and still have feeling downstairs so they can have sex. With most phalloplasty they can have penetrating under sex as well.
