Pregnancy in transgender men ============================ * Kimberley G.S. Thornton * Fiona Mattatall ## Routine care for transgender men should include discussions of fertility goals Fertility planning for all transgender men, particularly those with a uterus, should be discussed at regular intervals without assumption of type of sexual activity or fertility goals.1 For patients aiming for pregnancy, clinicians should discuss both medical and psychosocial expectations from preconception to postpartum.2,3 ## Testosterone is not a form of contraception, even in patients who are amenorrheic Transgender men with a uterus are at risk of unplanned pregnancy. Limited literature suggests similarly high rates of unplanned pregnancies in this population as in ciswomen and similar uptake of all contraceptive options, from barrier methods to hormonal contraceptives.1 Oral contraceptives may be used concurrently with androgenic hormone therapy. ## Preconception counselling in transgender men must include discussion around continuation of testosterone therapy Testosterone has teratogenic effects; specifically it can cause abnormal urogenital development in a female fetus. Therefore, testosterone should not be used while attempting conception or during pregnancy.1,4 ## Whether pregnant transgender men are at higher risk of peripartum complications is unknown No high-quality data are available regarding the incidence of pregnancy complications (e.g., gestational diabetes or hypertension) for transgender men.2 Vaginal birth is possible for transgender men, and counselling should include all options to optimize patient agency and birth experience. 2,3,5 Chestfeeding can be explored postpartum if the patient chooses.2,3 ## Psychosocial support is a critical component of pregnancy care for transgender men Few gender-sensitive resources on pregnancy exist for transgender men, but this does not reflect lack of need.2 Fears of stigmatization by their community, the wider population and health care providers are prevalent. Inclusive and sensitive care includes attention to pronouns, environment and language (such as “chest” instead of “breast”).2,3,5 *CMAJ* invites submissions to “Five things to know about …” Submit manuscripts online at [http://mc.manuscriptcentral.com/cmaj](http://mc.manuscriptcentral.com/cmaj) ## Footnotes * **Competing interests:** Fiona Mattatall is co-chair of the Transgender Working Group of the Society of Obstetricians and Gynaecologists of Canada.
