P–477 The child’s right to know vs. the parents’ right not to tell: the attitudes of couples undergoing fertility treatments towards identity-release gamete donation

Study question Do couples undergoing assisted reproduction treatments (ART) have a different perception of anonymous vs identity-release gamete donation than a population interested in the subject? Summary answer Compared with a population interested in the subject, more couples undergoing ART believed the child shouldn’t be given information that would identify the gamete-donor. What is known already Recent research has investigated the psychological well-being of parents and children born through gamete donation, focusing on the possibility of having the donor’s identity revealed. Gamete donors have traditionally been anonymous to recipients and offspring; however, there is a global trend towards programs using donors that are identifiable to the resulting offspring at maturity. While some countries only allow the use of identity-release egg donation, others only allow anonymous-donation, and in some countries both types of donation are practiced. However, the attitudes concerning anonymous vs identity-release gamete donation, in a country where only anonymous donation is allowed, are still unknown. Study design, size, duration This cross-sectional study was performed from 01/Sep/2020 to 15/Dec/2020. For that, surveys through online-platforms were conducted, including either patients undergoing ART, (ART-group, n = 358) or those interested in the subject, who accessed the website of a university-affiliated IVF-center (interested-group, n = 122). Participants in the ART-group were invited via e-mail, with a cover-letter outlining the survey and a link to access it and participants in the interested-group accessed the questionnaire via website. Participants/materials, setting, methods The survey collected information on demographic characteristics and the participant’s attitudes towards anonymity of gamete donors. The questions were: (i) In the case of children conceived through ART, do you believe that revealing the method of conception may affect the relationship between children and their parents? (ii) Once the method of conception is revealed, do you believe that the child has the right to know the gamete donor? (iii) If yes, when? Main results and the role of chance Most of the participants answered that the relationship between children and parents wouldn’t be affected by the child’s knowledge of the origin of their conception, regardless of the group (83.6% vs 82.7%, for ART-group and interested-group, respectively, p = 0.868). Most participants in the ART-group answered that the sperm donor identity shouldn’t be revealed to the child, while only half of the interested-group stated the same (65.4% vs 50.8%, p = 0.044). The same result was observed when participants were asked if the oocyte donor should be identifiable (64.8% vs 50.8%, p = 0.050). When asked when the donor’s identity should be revealed to the child, no significant differences were noted in the responses among the groups (p = 0.868). Most of the participants who believe that the child has the right of learning the donor’s identity, stated that “the donor’s identity should be revealed if the child questions its biological origin” (67.2% vs 67.5%, for ART-group and interested-group, respectively). “Since birth” was the second most common response, (21.0% vs 19.7%, for ART-group and interested-group, respectively), while “when the child turns 18 years-old” (9.2% vs 11.2%, for ART-group and interested-group, respectively), and “sometime during teenage years” (2.5% vs 2.4%, for ART-group and interested-group, respectively) were less common answers. Limitations, reasons for caution Lack of adequate opportunities to conduct face to face interview and lack of knowledge of the real state of the website participants, concerning infertility or being involved in ART. The retrospective nature of the study and the small sample size may also be reasons for caution, Wider implications of the findings: It has been discussed that, whether or not children or parents are harmed by knowing their biological origins, donor offspring have the right to know. However, when facing the situation, couples undergoing ART would argue that in case of gamete donation, there are reasons for not telling the child. Trial registration number Not applicable
