Fertility preservation and family-building in transgender and non-binary patients: 14 years at a UK centre

How is assisted reproductive technology used by trans and/or non-binary (TNB) individuals and their partners at London Women's Clinic?

This retrospective observational study examined treatments undertaken by TNB people at London Women's Clinic between 2011 and 2025. Demographic information on patients' age, body mass index, anti-Mullerian hormone, antral follicle count and history of gender-affirming hormone therapy/surgery was analysed. Outcomes included the types of treatment pursued, ongoing pregnancies, and live births.

Sixty-four individuals who identified as TNB (n = 42) or had a TNB partner (n = 22) attended the clinic. Treatments included egg freezing (22 cycles), intrauterine insemination (IUI; 17 cycles) and IVF (25 cycles). A minority of IVF cycles involved intra-partner donation (reciprocal IVF; 2/25) or donor eggs (2/25). Three couples' journeys involved surrogacy arrangements. Most TNB individuals attended the clinic with a partner (n = 30), with the exception of those undertaking egg freezing. Of the individuals/couples attempting pregnancy (n =24), most (n =20) were using donor spermatozoa, with the exception of four couples (two involving transgender women who had frozen spermatozoa, and two involving cisgender men). Thirteen live births were achieved and four individuals were discharged from the clinic with ongoing pregnancies.

TNB individuals in the UK are successfully using the spectrum of assisted reproduction options, often with donor gametes and occasionally surrogacy, to build families. In this study, IVF out-performed IUI, underscoring that with inclusive, legally informed care pathways, family formation for TNB patients is both feasible and effective.
