Transgender Hormone Therapy Male-to-Female

Transgender Hormone Therapy Male-to-Female

What is Feminizing Hormone Therapy?

Feminizing hormone therapy is used to induce physical changes in your body caused by female hormones during puberty (secondary sex characteristics) to promote the matching of your gender identity and your body (gender congruence). If feminizing hormone therapy is started before the changes of male puberty begin, male secondary sex characteristics, such as increased body hair and changes in voice pitch, can be avoided. Feminizing hormone therapy is also referred to as cross-sex hormone therapy.

During feminizing hormone therapy, you'll be given medication to block the action of the hormone testosterone. You'll also be given the hormone estrogen to decrease testosterone production and induce feminine secondary sex characteristics. Changes caused by these medications can be temporary or permanent. Feminizing hormone therapy can be done alone or in combination with feminizing surgery.

Before Feminizing Hormone Therapy

Why it's done

Feminizing hormone therapy is used to alter your hormone levels to match your gender identity. Typically, people who seek feminizing hormone therapy experience distress due to a difference between experienced or expressed gender and sex assigned at birth (gender dysphoria). To avoid excess risk, the goal is to maintain hormone levels in the normal range for the target gender.

Feminizing hormone therapy can:

. Make gender dysphoria less severe

. Reduce psychological and emotional distress

. Improve psychological and social functioning

. Improve sexual satisfaction

. Improve quality of life

Although use of hormones is currently not approved by the Food and Drug Administration for the treatment of gender dysphoria, research suggests that it can be safe and effective.

If used in an adolescent, hormone therapy typically begins at age 16. Ideally, treatment starts before the development of secondary sex characteristics so that teens can go through puberty as their identified gender. Hormone therapy is not typically used in children.

Feminizing hormone therapy isn't for all Trans women. Your doctor might discourage feminizing hormone therapy if you:

. Had or have a hormone-sensitive cancer, such as prostate cancer

. Have a thromboembolic disease, such as when a blood clot forms in one or more of the deep veins of your body (deep vein thrombosis) or a blockage in one of the pulmonary arteries in your lungs (pulmonary embolism)

. Have uncontrolled significant mental health issues

What is Gender dysphoria?

Gender dysphoria is a condition where a person experiences discomfort or distress because there's a mismatch between their biological sex and gender identity. It's sometimes known as gender incongruence.

Biological sex is assigned at birth, depending on the appearance of the genitals. Gender identity is the gender that a person "identifies" with or feels themselves to be.

While biological sex and gender identity are the same for most people, this isn't the case for everyone. For example, some people may have the anatomy of a man, but identify themselves as a woman, while others may not feel they're definitively either male or female.

This mismatch between sex and gender identity can lead to distressing and uncomfortable feelings that are called gender dysphoria. Gender dysphoria is a recognized medical condition, for which treatment is sometimes appropriate. It's not a mental illness.

Some people with gender dysphoria have a strong and persistent desire to live according to their gender identity, rather than their biological sex. These people are sometimes called transsexual or Trans people. Some Trans people have treatment to make their physical appearance more consistent with their gender identity.

What causes gender dysphoria?

Gender development is complex and there are many possible variations that cause a mismatch between a person’s biological sex and their gender identity, making the exact cause of gender dysphoria unclear.

Occasionally, the hormones that trigger the development of biological sex may not work properly on the brain, reproductive organs and genitals, causing differences between them. This may be caused by:

. Additional hormones in the mother’s system – possibly as a result of taking medication

. The foetus’ insensitivity to the hormones, known as androgen insensitivity syndrome (AIS) – when this happens, gender dysphoria may be caused by hormones not working properly in the womb.

Gender dysphoria may also be the result of other rare conditions, such as:

. Congenital adrenal hyperplasia (CAH) – where a high level of male hormones are produced in a female foetus. This causes the genitals to become more male in appearance and, in some cases, the baby may be thought to be biologically male when she is born.

. Intersex conditions – which cause babies to be born with the genitalia of both sexes (or ambiguous genitalia). Parents are recommended to wait until the child can choose their own gender identity before any surgery is carried out.

Risks and Complications of feminizing hormone therapy

Talk to your doctor about the changes in your body and any concerns you might have. Complications of feminizing hormone therapy might include:

. A blood clot in a deep vein (deep vein thrombosis) or in a lung (pulmonary embolism).

. High triglycerides, a type of fat (lipid) in your blood

. Gallstones

. Weight gain

. Elevated liver function tests

. Decreased libido

. Erectile dysfunction

. Infertility

. High potassium (hyperkalemia)

. High blood pressure (hypertension)

. Type 2 diabetes

. Cardiovascular disease, when at least two other cardiovascular risk factors are present

. Excessive prolactin in your blood (hyperprolactinemia) or a condition in which a noncancerous tumor (adenoma) of the pituitary gland in your brain overproduces the hormone prolactin (prolactinoma)

Current evidence indicates that there is no increased risk of breast cancer.

Your fertility

Because feminizing hormone therapy might reduce your fertility, you'll need to make decisions about future childbearing before starting treatment. The risk of permanent infertility increases with long-term use of hormones, especially when hormone therapy is initiated before puberty. Even after discontinuation of hormone therapy, testicular function might not recover sufficiently to ensure conception.

If you want to have biological children, talk to your doctor about freezing your sperm (sperm cryopreservation) before beginning feminizing hormone therapy.

Other side effects of estrogen use in Trans women include reduced libido, erectile function and ejaculation. Erectile function might improve with the use of oral medications such as sildenafil (Viagra) or tadalafil (Adcirca, Cialis).

How you prepare

Before starting feminizing hormone therapy, your doctor will evaluate your health to rule out or address any medical conditions that might affect or contraindicate treatment. The evaluation might include:

. A review of your personal and family medical history

. A physical exam, including an assessment of your external reproductive organs.

. Lab tests measuring your lipids, blood sugar, blood count, liver enzymes, electrolytes and the hormone prolactin.

. A review of your immunizations

. Age- and sex-appropriate screenings

. Identification and management of tobacco use, drug abuse, alcohol abuse, HIV and other sexually transmitted infections.

. Discussion about sperm freezing (sperm cryopreservation)

. Discussion about use of potentially harmful treatment approaches, such as unprescribed hormones, industrial-strength silicone injections or self-castration

You might also need a mental health evaluation by a provider with expertise in transgender health. The evaluation might assess:

. Your gender identity and dysphoria

. The impact of your gender identity at work, school, home and social environments, including issues related to discrimination, relationship abuse and minority stress.

. Mood or other mental health concerns

. Sexual health concerns

. Risk-taking behaviors, including substance use and use of nonmedical-grade silicone injections or unapproved hormone therapy or supplements

. Protective factors such as social support from family, friends and peers

. Your goals, risks and expectations of treatment and your future plans for your care

Adolescents younger than age 18, accompanied by their parents or guardians, also should see doctors and mental health providers with expertise in pediatric transgender health to discuss the risks of hormone therapy, as well as the effects and possible complications of gender transition.

During Feminizing Hormone Therapy

What you can expect

During the procedure

Typically, you'll begin feminizing hormone therapy by taking the diuretic spironolactone (Aldactone) at doses of 100 to 200 milligrams daily. This blocks male sex hormone (androgen) receptors and can suppress testosterone production.

After six to eight weeks, you'll begin taking estrogen to decrease testosterone production and induce feminization. Estrogen can be taken in a variety of methods, including as a pill, by injection or in skin preparations, such as a cream, gel, spray or patch. Don't take estrogen orally, however, if you have a personal or family history of venous thrombosis. Use of gonadotropin-releasing hormone (Gn-RH) analogs to suppress testosterone production might allow you to take lower estrogen doses and wouldn't require the use of spironolactone. However, Gn-RH analogs are more expensive.

Additional therapies might include:

. Progesterone that's been reduced to tiny particles (micronized), which might improve breast development

. Finasteride (Propecia) or topical minoxidil (Rogaine) or both for people prone to male-pattern baldness

After Feminizing Hormone Therapy

After the procedure

Feminizing hormone therapy will begin producing changes in your body within weeks to months. Your timeline might look as follows:

. Decreased libido. This will begin one to three months after starting treatment. The maximum effect will occur within one to two years.

. Decreased spontaneous erections. This will begin one to three months after treatment. The maximum effect will occur within three to six months.

. Slowing of scalp hair loss. This will begin one to three months after treatment. The maximum effect will occur within one to two years.

. Softer, less oily skin. This will begin three to six months after treatment.

. Testicular atrophy. This will begin three to six months after treatment. The maximum effect will occur within two to three years.

. Breast development. This will begin three to six months after treatment. The maximum effect will occur within two to three years.

. Redistribution of body fat. This will begin three to six months after treatment. The maximum effect will occur within two to five years.

. Decreased muscle mass. This will begin three to six months after treatment. The maximum effect will occur within one to two years.

. Decreased facial and body hair growth. This will begin six to 12 months after treatment. The maximum effect will occur within three years.


During your first year of feminizing hormone therapy, you'll need to see your doctor approximately every three months for checkups, as well as anytime you make changes to your hormone regimen. Your doctor will:

. Document your physical changes

. Monitor your hormone concentration, and use the lowest dose necessary to achieve desired physical effects.

. Monitor changes in your lipids, fasting blood sugar, blood count, liver enzymes and electrolytes that could be caused by hormone therapy.

. Monitor your mental health stability

After feminizing hormone therapy, you will also need routine preventive care, including:

. Breast cancer screening. This includes monthly breast self-exams and age-appropriate mammography screening after five to 10 years of estrogen therapy.

. Supplementation. This includes standard calcium and vitamin D supplementation, along with bone density assessment according to the female age-appropriate recommendations.

. Prostate cancer screening. This should be done according to age-appropriate recommendations. With estrogen treatment, your PSA is expected to decrease by about 50 percent.
