Abstract

Study question
Is adolescents’ intention to request information about their open-identity donor associated with donor type, family form, or adolescent gender?

Summary answer
Adolescent girls were less likely than boys to intend requesting information about their open-identity donor, irrespective of donor type (oocyte/sperm) and family form.

What is known already
Individuals conceived by open-identity gamete donation have the right to obtain identifying information about their donor. However, there is little knowledge about the level of interest in requesting such information as donor conceived (DC) persons approach the age when they can obtain this information, as well as their interest in contact with the donor and persons who share the same donor. The present study aims to investigate factors associated with adolescentś intention to request information about their open-identity donor and their interest in contact with the donor and donor-siblings.

Study design, size, duration
The study is based on the fifth wave of data collection in the prospective, longitudinal Swedish Study on Gamete Donation, conducted in 2022-2023. Participating parents provided consent to contact their donor conceived children (ages 13-16), who were approached with a postal/web-survey. A total of 98 adolescents participated (77% response rate): adolescents conceived with sperm donation in lesbian-couple (SD-lesb, n = 48) and heterosexual-couple families (SD-het, n = 27), and those conceived with oocyte-donation in heterosexual-couple families (OD-het, n = 23).

Participants/materials, setting, methods
The study was part of the longitudinal Swedish Study on Gamete Donation, including couples starting gamete donation treatment at university hospitals between 2005-2008. The current fifth wave of data collection is the first to include children self-report. Participating adolescents included 48 girls and 50 boys with a mean age of 14.44 for girls and 14.28 for boys. The survey comprised of socio-demographics, study-specific items and validated instruments. Data was analyzed with multinominal regression analysis.

Main results and the role of chance
Roughly half (56%) of the adolescents intended to request information about their open-identity donor, while 12% planned not to and 32% were unsure. Multinominal regression analysis showed a significant effect for gender, but not for family/donation type (SD-lesb, SD-het, OD-het). Girls were significantly more likely than boys to state that they did not intend to request donor information (OR = 4.66, 95% CI [1.13, 19.34]). Among those adolescents who planned to request identifying donor information, a subset stated that they intended to contact the donor (30% boys, 15% girls). Concerning interest in contact with persons who share the same donor, participants were evenly divided between an interest (29%) or no interest (27%) and remaining were unsure (44%). No differences were found with regard to groups or gender.

Limitations, reasons for caution
The relatively small sample size could affect the results of the statistical analysis, making it harder to get significant results and creating large confidence intervals. There is a possible attrition bias with less well-functioning families not participating. The study was conducted within the Swedish context of identity-release gamete donation.

Wider implications of the findings
Approaching adulthood, about half of donor-conceived individuals plan to request information about their open-identity donor, highlighting that many DC people want this possibility. The gender difference found contrasts with earlier research findings and points to the need to understand the specific motivations of different groups of DC adolescents.
