Résumé
The application of fertility preservation, initially intended for oncological patients prior to gonadotoxic treatment, has extended in recent years to transgender and gender-non-conforming individuals undergoing therapy for gender compatibility. To examine semen quality and survival in transgender women pursuing semen cryopreservation in the presence or absence of gender-affirming hormonal medication. In this retrospective cohort study, we reviewed data of 74 consecutive transgender women presenting for semen cryopreservation at a single center between 2000 and 2019. Semen parameters before and after cryopreservation were compared to a control group composed of 100 consecutive sperm bank donor candidates. A subgroup analysis of subjects who had used gender-affirming hormonal treatment was also performed. Compared to the control group, transgender women had lower total sperm count (144.0 vs. 54.5 million, respectively, p < 0.001), lower sperm motility percentage (65.0% vs. 51.0%, respectively, p < 0.001), and lower total motile sperm count (94.0 vs. 27.0 million, respectively, p < 0.001). Values were further decreased in transgender women who had received hormonal treatment before sperm cryopreservation. Post-thawing motility rate remained lower in the transgender group compared to the control group (20.0% vs. 45.0%, respectively, p < 0.001), and the total motile count remained lower as well (2.7 vs. 9.0 million, respectively, p < 0.001). Following sperm cryopreservation, the post-thaw decreases in total motile sperm count were higher in the transgender group compared with the control group (91.5% vs. 90.0%). Further subdivision in the transgender group showed that the decrease in total motile sperm count was lower for transgender women who did not use gender-affirming hormonal treatment compared to those who did (-89.7% vs. -92.6%, respectively, p < 0.01). Sperm parameters in transgender women are poor compared to candidates for sperm donation representing the general population. Specimens collected after discontinuation of gender-affirming hormone treatments were further impaired. Moreover, post-thawing sperm total motile count, motility, and overall sperm survival were reduced in transgender women.

BACKGROUND
The application of fertility preservation, initially intended for oncological patients prior to gonadotoxic treatment, has extended in recent years to transgender and gender-non-conforming individuals undergoing therapy for gender compatibility.
OBJECTIVES
To examine semen quality and survival in transgender women pursuing semen cryopreservation in the presence or absence of gender-affirming hormonal medication.
MATERIALS AND METHODS
In this retrospective cohort study, we reviewed data of 74 consecutive transgender women presenting for semen cryopreservation at a single center between 2000 and 2019. Semen parameters before and after cryopreservation were compared to a control group composed of 100 consecutive sperm bank donor candidates. A subgroup analysis of subjects who had used gender-affirming hormonal treatment was also performed.
RESULTS
Compared to the control group, transgender women had lower total sperm count (144.0 vs. 54.5 million, respectively, p < 0.001), lower sperm motility percentage (65.0% vs. 51.0%, respectively, p < 0.001), and lower total motile sperm count (94.0 vs. 27.0 million, respectively, p < 0.001). Values were further decreased in transgender women who had received hormonal treatment before sperm cryopreservation. Post-thawing motility rate remained lower in the transgender group compared to the control group (20.0% vs. 45.0%, respectively, p < 0.001), and the total motile count remained lower as well (2.7 vs. 9.0 million, respectively, p < 0.001). Following sperm cryopreservation, the post-thaw decreases in total motile sperm count were higher in the transgender group compared with the control group (91.5% vs. 90.0%). Further subdivision in the transgender group showed that the decrease in total motile sperm count was lower for transgender women who did not use gender-affirming hormonal treatment compared to those who did (-89.7% vs. -92.6%, respectively, p < 0.01).
DISCUSSION AND CONCLUSION
Sperm parameters in transgender women are poor compared to candidates for sperm donation representing the general population. Specimens collected after discontinuation of gender-affirming hormone treatments were further impaired. Moreover, post-thawing sperm total motile count, motility, and overall sperm survival were reduced in transgender women.
