Gender-Affirming Gynecology

TRANSforming gynecology: An introduction to hormone therapy for the obstetrician/gynecologist


 

Incorporating gender-nonconforming patients into practice can seem like a daunting task at first. However, obstetricians/gynecologists, midwives, and other advanced women’s health care practitioners can provide quality care for both transgender men and women. Basic preventative services such as routine health and cancer screening and testing for sexually transmitted infections does not require specialized training in transgender health. In fact, administration of hormonal therapy and some surgical interventions are well within the scope of practice of the general obstetrician/gynecologist, as long as the provider has undergone appropriate training to achieve expertise. For example, organizations such as the World Professional Association for Transgender Health (WPATH) not only provides standards of care regarding the treatment of transgender individuals, but they also have training and educational opportunities targeted at providers who wish to become certified in more advanced care of the transgender patient. If an obstetrician/gynecologist is interested in prescribing hormone therapy, seeking further training within the field is a must.

It is important to remember that the process by which transgender individuals express their gender is a spectrum. Not all patients who identify as transgender will seek hormone therapy or surgical procedures. However, even if a provider has not undergone more specific training to administer hormone therapy, it is still very important to have a basic understanding of the hormones, routes of administration, and side effects.

While cross-sex hormone therapy does differ in practice, compared with hormone replacement therapy in cisgender counterparts, the principles are relatively similar. Testosterone therapy is the mainstay treatment for transgender men who desire medical transition.1,2 The overall goal of therapy is to achieve testosterone levels within the cisgender male physiologic range (300-1000 ng/dL). While the most common route of administration is subcutaneous or intramuscular injections in weekly, biweekly, or quarterly intervals, other routes may include daily transdermal patches and gels or oral formulations.1 Within the first few months of use, patients will notice signs of masculinization such as increased facial and body hair, increased muscle mass, increased libido, and amenorrhea. Other changes include male-pattern hair loss, clitoromegaly, redistribution of fat, voice deepening, and mood changes.1

Hormone therapy for transgender women is a bit more complicated as estrogen alone will often not achieve feminizing characteristics that are satisfying for patients.3 Estrogen therapy can include oral formulations of 17-beta estradiol or conjugated estrogens, although the latter is typically avoided because of the marked increase in thromboembolic events. Estrogens can also be administered in sublingual, intramuscular, or transdermal forms. Antiandrogens are often required to help decrease endogenous testosterone levels to cisgender female levels (30-100 ng/dL).3 Spironolactone is most commonly prescribed as an adjunct to estrogen therapy. Finasteride and GnRH agonists like leuprolide acetate can also be added if spironolactone is not effective or not tolerated by the patient. Feminizing effects of estrogen can take several months and most commonly include decreased spontaneous erections, decreased libido, breast growth, redistribution of fat to the waist and hips, decreased skin oiliness, and softening of the skin.3

Overall, hormone therapy for both transgender men and women is considered effective, safe, and well tolerated.4 Monitoring is typically performed every 3 months within the first year after initiating hormone therapy, and then continued every 6-12 months thereafter. Routine screening for all organs and tissues present (e.g. prostate, breast) should be undertaken.3 While this simply highlights the therapy and surveillance for patients, it is important to remember that many transgender men and women will see an obstetrician/gynecologist at some interval during their transition. Ultimately, it is paramount that we as obstetricians/gynecologists have a basic understanding of the treatments available so we can provide our patients with competent and compassionate care.
