Every ob.gyn. expects that the topic of gender will come up at some point in a patient’s pregnancy. “When will I find out the gender?” asks the 24-year-old at her first prenatal visit. “We want the gender to be a surprise!” exclaims the couple at their anatomy scan for their second in vitro fertilization pregnancy. “Do you know what you’re having?” asks the obstetrician anticipating an imminent delivery.

The topic of gender is in fact so ingrained in our practice that we don’t bat an eye when approached with questions about fetal gender. But what exactly are we talking about when we discuss the gender of an unborn baby?
As we established in our previous column, gender identity is an internal experience of gender that one feels to be a part of oneself. So, then, what does an ultrasound actually reveal? Objectively, ultrasound can show the provider the presence or absence of a hyperechoic anatomical structure between the fetal legs that may become a penis, a vagina, or an ambiguous form of genitalia. While ultrasound is an incredible tool for anatomical and other forms of antenatal testing, ultrasound cannot detect identity characteristics because identities are, by definition, socially and internally experienced without respect to anatomy.

The distinction between gender identity and sex assigned at birth in discussions of antenatal ultrasonography is more than just a simple problem of semantics or vocabulary. To describe a fetus as a boy or a girl based on the presence/absence of a projection between the fetal legs seen on ultrasound is to reinforce the idea that gender identity and sex assigned at birth are equivalent. This conflation also erases nonbinary, genderqueer, and many other groups that identify with genders other than “boy” or “girl.” To be clear, unborn fetuses do not have a gender identity. Studies have shown that children begin to self-label their gender as early as 18-24 months of age, and similarly those who grow up to inhabit gender-nonconforming identities usually already are starting to show signs of their nonconformity starting at age 2 years.1 Some of the deepest traumas that trans and gender-nonconforming people experience are rated to the enforcement of unwritten gender laws during early childhood that are applied based on the sex assigned at birth.
Obstetricians can help to break the cycle of inappropriate gender assignment by correctly using the terms “gender” and “sex assigned at birth.” One opportunity for addressing patients’ questions about fetal gender might be to avoid the term “gender” altogether when discussing fetal sex assigned at birth, emphasizing instead what fetal ultrasound is actually able to do: Give us information about the appearance of external genitalia to help predict what sex will be assigned at birth.2 We have used this strategy when performing anatomy scans, and our experience has been that patients often will make their own assumptions about what it means to see certain external genitalia on ultrasound between the fetal legs. Motivated providers who want to go the extra mile may use a patient’s exclamation about their understanding of the fetus’s gender as an opportunity to educate the patient on the distinction between gender and sex assigned at birth, but even just smiling and moving onto the next part of the scan is an appropriate way of maintaining an atmosphere of inclusion and respect.
Dr. Andrea B. Joyner
One of the roots of gender-based violence and gender dysphoria later in life is the conflation of gender and sex assigned at birth. While there is an entire social and political framework that enforces and polices gender after birth, the obstetrician can take steps to break the cycle starting before the birth has even occurred. Obstetricians are tasked with the unique challenge of providing care for the mother-fetus dyad, and much of the work is in setting up the fetus for the best possible life. Our scope of inclusion should be sufficiently wide to account for nonanatomical variations that could develop later in life in the infants we deliver.
