Initiation and outcomes of women pursuing planned fertility preservation

To study cycle outcomes of women who choose to pursue oocyte cryopreservation, using published age-specific oocyte recommendations.

Retrospective cohort.

Clinic.

A total of 5,915 patients seeking planned oocyte cryopreservation, 3,504 ultimately underwent ovarian stimulation with oocyte retrieval and cryopreservation, 425 of this cohort subsequently thawed with intent to use embryo transfer.

Planned oocyte cryopreservation.

Planned oocyte cryopreservation consultation, fertility preservation cycle(s) and ovarian stimulation outcomes.

A total of 5,915 women were seen in the initial consultation for planned fertility preservation (2012-2022). Ethnicity and the highest level of education were significant in predicting who would move forward with oocyte stimulation for fertility preservation. Women who reported working within the law and public policy and in the fields of health and medicine were statistically more likely to proceed with a cycle than those who listed other occupations. Of 3,504 women in the study cohort who underwent ovarian stimulation and egg retrieval, 1,331 (38.0%) achieved the age-based recommended number of oocytes to freeze. Only 57 (4.3%) of these women who met their age-based oocyte goal did so after their initial cryopreservation cycle. There was a significant association between ethnicity and number of cryopreservation cycles, specifically showing that Black or African American women were less likely to complete two or more cycles. Patients whose education background included graduate or professional degrees were more likely to have completed more than one cycle.

Self-identified ethnicity was significantly associated with the odds of moving forward with oocyte stimulation for fertility preservation and egg retrieval after initial consultation with ethnic minorities significantly less likely to continue treatment. Of those who undergo egg freezing, most women pursue more than one stimulation and cryopreservation cycle, yet the majority never meet their recommended number to freeze.
