Executive summary
Becoming pregnant after taking testosterone typically requires stopping testosterone, restoring ovulation (sometimes with medications), and choosing either unassisted conception or assisted reproductive techniques such as intrauterine insemination (IUI) or in vitro fertilization (IVF); fertility preservation before testosterone is an alternative pathway for those who anticipate wanting biological children [1] [2] [3]. Clinical guidance stresses that testosterone is not a reliable contraceptive and is contraindicated during attempts to conceive and pregnancy because of teratogenic risks to a fetus [4] [5].
1. Pause testosterone and address teratogenic risk
The first medical step is stopping masculinizing testosterone under medical supervision because exogenous testosterone can cause abnormal urogenital development in a female fetus and is therefore contraindicated when attempting conception or during pregnancy [5] [6]. Clinical programs and fertility guidelines consistently advise cessation of testosterone prior to conception attempts and emphasize the need for prompt consultation if pregnancy is suspected while on testosterone [6] [1].
2. Wait for ovulation to resume — variable timelines and uncertainty
After stopping testosterone, many transgender men experience the return of menses and ovulation within weeks to months — studies report most resume menstruation within three to six months, though some conceive before periods return and others may need longer or never regain regular ovulation, reflecting incomplete data on long-term ovarian effects of testosterone [1] [7] [2]. Because the timing is variable and research remains limited, clinicians monitor hormone markers and menstrual return rather than relying on fixed timelines [8].
3. Use ovulation induction or fertility medications if needed
If ovulation does not resume or timing is uncertain, fertility clinics can use medications to stimulate follicle development and induce ovulation — a standard approach for trans men attempting pregnancy after testosterone comparable to cisgender infertility treatments [8] [2]. Published reviews and clinic guidance note that assisted methods often mirror standard reproductive protocols, though data on outcomes in those with prior testosterone exposure are still emerging [8] [9].
4. Choose conception pathway: natural sex, IUI, or IVF
Options include unassisted intercourse if a partner provides sperm, intrauterine insemination (IUI) as a lower-intervention assisted method, or IVF with egg retrieval and embryo transfer for greater control — IVF also allows use of frozen eggs or donor gametes when indicated [2] [1] [3]. Several case series and clinic reports document successful pregnancies after pausing testosterone, and some studies found similar oocyte retrieval outcomes in people with prior testosterone compared with controls, although larger studies are needed [8] [7].
5. Consider fertility preservation before testosterone and alternative family-building
Because the long-term impact of testosterone on egg quality and ovarian response is not fully understood, many experts recommend discussing options such as oocyte or embryo cryopreservation before initiating hormone therapy; ovarian tissue cryopreservation is also discussed though feasibility varies [1] [10] [8]. For those who prefer to avoid pregnancy or who have diminished ovarian reserve after testosterone, options include using previously frozen gametes, embryo transfer to a gestational carrier, or adoption [3] [1].
6. Medical follow-up, monitoring, and psychosocial care during pregnancy
Once pregnant, standard prenatal care applies, but clinicians should monitor for complications and counsel on hormone safety; continuous testosterone is contraindicated during pregnancy and lactation considerations (including chestfeeding) are individualized [5] [11]. Reporting and reviews highlight gaps in provider knowledge and the need for gender-sensitive reproductive care, with advocacy groups pushing for more research and inclusive services [12] [5].
7. Limits of current evidence and competing incentives
Available evidence includes case reports, clinic series, and small comparative studies that generally show pregnancy is possible after testosterone but acknowledge limited long-term data on gamete quality and uterine receptivity; fertility clinics and advocacy organizations may emphasize different points — clinics focus on technical options (egg retrieval, IVF, surrogacy) while advocacy groups stress access, informed consent, and the psychosocial burdens of pausing hormones [8] [3] [1]. Given this mix of clinical optimism and scientific uncertainty, individualized counseling and transparent discussion of unknowns remain essential [7].
