Transgender pregnancy

Transgender pregnancy is the gestation of one or more embryos or fetuses by transgender people. As of 2024,^[update] the possibility is restricted to those born with female reproductive systems. However, transition-related treatments may impact fertility. Transgender men and nonbinary people who are or wish to become pregnant face social, medical, legal, and psychological concerns. As uterus transplantations are currently experimental, and none have successfully been performed on trans women, they cannot become pregnant.

Pregnancy is possible for transgender men who retain functioning ovaries and a uterus, such as in the case of Thomas Beatie.^[1] Regardless of prior hormone replacement therapy (HRT) treatments, the progression of pregnancy and birthing procedures are typically the same as those of cisgender women. Delivery options include conventional methods such as vaginal delivery and cesarean section, and patient preference should be taken into consideration in order to reduce gender dysphoric feelings associated with certain physical changes and sensations.^[2] It has been shown that historical HRT use may not negatively impact ovarian stimulation outcomes, with no significant differences in the markers of follicular function or oocyte maturity between transgender men with and without a history of testosterone use.^[3]

Among the wide array of transgender-related therapies available, including surgical and medical interventions, some offer the option of preserving fertility while others may compromise one's ability to become pregnant (including bilateral salpingo-oophorectomy and/or total hysterectomy).

Exposing a fetus to high levels of exogenous testosterone may damage an embryo or fetus, especially the urogenital system of a female fetus.^[4] This is particularly important in the first trimester when many pregnancies have not been discovered yet.^[5] Previous studies of pregnancies in women suggest that high levels of endogenous androgens are associated with reduced birth weight, although it is unclear how prior testosterone in a childbearing trans person may affect birth weight.^[2] Future pregnancies can be achieved by oophyte banking, but the process may increase gender dysphoria or may not be accessible due to lack of insurance coverage.^[6]

Additionally, patients experiencing amenorrhea (a common side effect of HRT) may experience additional challenges in identifying early pregnancies due to the lack of regular menstrual cycling that could indicate a pregnancy if missed, for example.^[5] For this reason, it is important for patients and healthcare practitioners to comprehensively discuss fertility goals, family planning and contraceptive options during gender-affirming care.^[5] Many trans men who had planned pregnancies were able to conceive within six months of stopping testosterone.^[6] Testosterone-induced changes to the reproductive tract may be partly or completely reversed after stopping HRT.

HRT for trans men eventually decreases fertility. Continued use of testosterone suppresses the ovarian cycle and uterine cycle, which would otherwise cause oocyte maturation, ovulation, and menstruation every month. Testosterone therapy also causes atrophy of the vagina and uterus.^[7] Testosterone use in trans men and other transmasculine individuals affects the ovaries, leading to an increased amount of ovarian cysts, which is also seen in cisgender women with PCOS. Individuals studied also displayed follicular atresia, overgrowth of the stroma, and the replacement of ovarian tissue with collagen. The uterine tubes of many trans men studied were also closed or partially closed; normally, the uterine tubes are clear, allowing for fertilized oocytes to move to the uterus. However, observation of trans men and studies on lab mice reveal that testosterone treatment does not affect the number of available gametes (eggs/sex cells).^[8]

In a study of American trans men, 28.3% reported that they were afraid of not being able to become pregnant because of hormone therapy. Because some trans men want to carry children, it is important for providers to discuss fertility preservation options with trans male clients before prescribing HRT.^[9]

Despite its effects on fertility, testosterone therapy is not an effective contraceptive. Trans men and nonbinary people who take testosterone may still become pregnant even if their periods have stopped.^[2][10] Trans men may experience unintended pregnancy,^[6][9] especially if they miss doses.^[6]

Another important postpartum consideration for trans men is whether to resume testosterone therapy. There is currently no evidence that testosterone enters breast milk in a significant quantity.^[11] However, elevated testosterone levels may suppress lactation and healthcare guidelines have previously recommended that trans men do not undergo testosterone therapy while chestfeeding (breastfeeding).^[12] Trans men who undergo chest reconstruction surgery may maintain the ability to chestfeed.^[13]

Chestfeeding is not off the table for many trans men who medically transition, but it is rarely discussed by doctors who prescribe testosterone or complete chest masculinization surgeries. While chestfeeding can be a dysphoric activity for some trans men and nonbinary people, some find it fulfilling and a practice that connects them to their baby.^[14]

Some chest masculinization surgeries prohibit people from chestfeeding at all, but some surgeries maintain the mammary glands and just remove breast tissue. With these surgeries, the baby can have trouble latching and milk supply may be diminished.^[15] This can be bypassed with medication and support from doctors.

For people that are attempting chestfeeding without chest masculinization surgery, Chest binding has an effect on milk supply. Binding for years or binding unsafely for long periods of time prior to pregnancy can negatively affect glandular tissue and chestfeeding ability, and binding during a chestfeeding period is not recommended, as it can cause mastitis.^[16]

Special consideration of the mental health of transgender people during pregnancy is important. It has previously been shown that transgender individuals often experience higher rates of suicidality than cisgender people and lesser degrees of social support from their environment and familial relationships.^[17][18] Relatedly, many transgender individuals experiencing pregnancy reported that choices of healthcare providers were substantially impacted by the views of the healthcare worker, and many transgender people prefer midwifery services rather than experience labor and delivery in a hospital.

Some individuals reported having gender dysphoria and feelings of isolation due to the public reception of their gender identity and drastic changes in appearance which occur during pregnancy, such as enlarged breasts.^[19] Some state feeling disconnected or alienated from their pregnant bodies. Both social gender dysphoria (related to perception by others) and physical gender dysphoria (perception of one's own body) can occur while a trans person is pregnant.^[20][21]

Unintended pregnancy can also be dangerous to a trans person's mental health. According to a study of American transgender men between the ages of 18 and 45, 30.5% reported being afraid of pregnancy.^[22] Unwanted pregnancy can cause severe gender dysphoria and suicidal ideation in trans people. One nonbinary person who performed a self-induced abortion stated,^[23]

[I used] blunt force to [my] abdomen. Considered drinking poison, as my insurance did not cover an abortion. Luckily, I was able to get on state insurance which did cover the procedure, so it did not come to that. I 100% would have done it. Dying was a better alternative to forced pregnancy.

According to the National Transgender Discrimination Survey, postpartum rates of suicide and depression in trans individuals has been found to be higher than the adult average.^[18] This may be attributed to factors such as lack of social support, discrimination, and lack of adequate healthcare practitioner training.^[18]

Transgender people, including trans men and nonbinary people, are more likely than the general population to experience homelessness, food insecurity, intimate partner violence, and adverse child experiences. All of these can impact pregnancy outcomes. Additionally, trans people experience minority stress and may be at higher risk of substance use than the general population. Some also report avoiding medical care or mistrusting medical professionals because of discrimination.^[24]

Some trans men who carry pregnancies are subjected to discrimination, which can include a variety of negative social, emotional, and medical experiences, as pregnancy is regarded as an exclusively feminine or female activity. Several studies indicate a lack of awareness, services, and medical assistance available to pregnant trans men.^[19] Inaccessibility to these services may lead to difficulty in finding comfortable and supportive services concerning prenatal care, as well as an increased risk for unsafe or unhealthy practices.

Unintended pregnancies can result in transgender men or nonbinary people considering or attempting self-induced abortion. Many transgender men report attempting a self-induced abortion because of lack of safe, effective abortion methods.^[23] Studies differ on abortion rates in trans men. Different studies report that between 12%^[9] and 21% of trans people's pregnancies end in abortions. Some trans people report choosing between abortion and suicide because pregnancy causes them intolerable gender dysphoria.^[23]

According to figures compiled by Medicare for Australia, one of the few national surveys as of 2020, 75 male-identified people gave birth naturally or via C-section in the country in 2016, and 40 in 2017.^[25]

Pregnancy is not possible for transgender women as they lack a female reproductive system. As of 2019, uterus transplantation has not been successfully performed in transgender women.^[26] The Danish transgender painter Lili Elbe died in 1931 from surgical complications following an attempt at such an operation.

Uterine transplantation, or UTx, is in its infancy and is not yet publicly available. As of 2019, in cisgender women, more than 42 UTx procedures had been performed, with 12 live births resulting from the transplanted uteri as of publication.^[27] The International Society of Uterine Transplantation (ISUTx) was established internationally in 2016, with 70 clinical doctors and scientists, and currently has 140 intercontinental delegates.^[28]

In 2012, McGill University published the "Montreal Criteria for the Ethical Feasibility of Uterine Transplantation", a proposed set of criteria for carrying out uterine transplants, in Transplant International.^[29] Under these criteria, and because no research has been conducted in genetic males, only a genetic female could ethically be considered a transplant recipient. The exclusion of trans women from candidacy is justified by the lack of research to determine how to conduct the surgery, rather than an inherent bar.^[30] In 2021, authors of the Montreal Criteria published a revised set of criteria in Bioethics with an ethical framework for consideration of genetic males' (and other genetic XY individuals') eligibility for uterine transplants.^[31]

Some trans women can induce lactation, allowing them to breastfeed babies they did not biologically birth. Practices such as medical lactation induction can simulate the changes of breasts during pregnancy and begin lactation with the assistance of medication. ^[32]

Non-binary people with a functioning female reproductive system can give birth.^[33]

Nonbinary people taking testosterone to transition must interrupt HRT in order to carry the pregnancy, as testosterone is a teratogen.^[4] Unintended pregnancies by non-binary people on testosterone therapy may be more common if they are on a low dose of testosterone.^[6] Nonbinary parents choose whether to be called "mom," "dad," or newly coined gender-neutral or nonbinary titles.^[34]

Non-binary people who have written or been profiled about their experiences of pregnancy include Rory Mickelson,^[35] Braiden Schirtzinger,^[36] and Mariah MacCarthy.^[37]

In 1583, an intersex person that had masculine gender expression reportedly became pregnant in Beaumaris, Wales.^[38]
