For anyone who hasn't looked at the draft SOC, I thought you might enjoy the following quote which explains why transgender people require specialist contraceptive advice.
Gender diverse individuals who currently have a penis and testicles may engage in sexual activity with individuals who have a uterus, ovaries, and tubes of any gender. Gender diverse people who have a penis and testicles can produce sperm even while on gender-affirming hormones (i.e.,estrogen), and although semen parameters are diminished among those who are currently using or who have previously used gender-affirming hormones, azoospermia is not complete and sperm inactivity is not totally suppressed(Adeleye, Reid, et al., 2019; Jindarak et al., 2018; Kent et al., 2018). Therefore, contraception needs to be considered if pregnancy is to be avoided in penis-in-vagina sexual activity between a person with a uterus, ovaries, and tubes and one witha penis and testicles,irrespective of the use of gender-affirming hormones by either partner. Currently, contraceptive methods available for useby the sperm-producing partner are primarily mechanical barriers (i.e.,external condoms, internal condoms),permanent sterilization (i.e.,vasectomy), andgender-affirming surgery (e.g.,orchiectomy, which also results in sterilization). Gender expansive contraceptive counseling that considers sperm producing, egg producing, and gestating partners (as relevant) is recommended.
