STUDY QUESTION

What structural (logistical) and psychological challenges do patients who cryopreserve oocytes or embryos for medical reasons face, including possible barriers to using their frozen materials?

SUMMARY ANSWER

The majority of women who underwent oocyte or embryo cryopreservation for medical reasons reported a desire to use their frozen oocytes or embryos but had been impeded by ongoing medical issues, the need for a gestational carrier, or the lack of a partner.

WHAT IS KNOWN ALREADY

Current data suggest that many women who have frozen oocytes or embryos for medical indications are concerned about the prospect of infertility and have unique emotional and financial needs that differ from patients with infertility. Further, most patients have not returned to use their cryopreserved materials.

STUDY DESIGN, SIZE, DURATION

This is a qualitative interview study of 42 people who cryopreserved between January 2012 and December 2021. Interviews were conducted between March 2021 and March 2022.

PARTICIPANTS/MATERIALS, SETTING, METHODS

All participants were cisgender women who had undergone oocyte or embryo cryopreservation for medical indications at an academic fertility center. Participants were invited to interview by email if they were younger than 40 years old when their oocytes or embryos were cryopreserved. Interviews were conducted over the internet and transcribed verbatim. Data were analyzed using thematic analysis with the constant comparison method.

MAIN RESULTS AND THE ROLE OF CHANCE

Saturation was reached at 42 interviews. The median age of participants was 35 years old (range 28–43) at interview and 31 years old (range 25–39) at cryopreservation. Of the 42 women, 30 had a cancer diagnosis, while 7 had non-cancer chronic medical conditions, and 5 had hereditary cancer susceptibility syndromes. There were 12 women who banked embryos and 30 who banked oocytes. The majority of women indicated a desire to use their cryopreserved materials, but many were unsure about how or when. Four had already used their frozen oocytes or embryos, while another four had conceived without assisted reproduction. The cryopreservation experience was described by the majority as highly emotionally challenging because they felt out of place among couples receiving infertility treatment and, for cancer patients, overwhelmed by the complex decisions to be made in a short time period. Common reported barriers to using frozen materials included ongoing medical issues preventing pregnancy, the need for a gestational carrier, the lack of a partner, and the desire for unassisted conception. Some were glad to have frozen oocytes or embryos to allow more time to meet a partner or if they were considering becoming single parents.

LIMITATIONS, REASONS FOR CAUTION

The majority of participants had their oocytes or embryos frozen at a single, urban, academic fertility center, which may limit generalizability. We also could not calculate a response rate because the snowball technique was used to identify additional participants, so did not know the total number of people invited to participate. Like other interview studies, our study may be subject to response bias because those who agreed to participate may have particularly positive or negative views about their experiences. Furthermore, the mean follow-up time since freezing was relatively short (3.3 years, median 2.7 years), which may not have been enough time for some patients to use their frozen materials.

WIDER IMPLICATIONS OF THE FINDINGS

Learning about the experiences of patients undergoing medically indicated oocyte and embryo cryopreservation can help clinicians better counsel these patients regarding decisions and hurdles they may encounter. We found that most patients had not returned to use their frozen materials because of ongoing medical issues, the need for a gestational carrier, lack of a partner, or the desire to attempt unassisted reproduction.
