Sperm donor conception and disclosure to children: a 10-year retrospective follow-up study of parental attitudes in one French center for the study and preservation of eggs and sperm (CECOS).

Objective: To evaluate the percentage of parents in one French center for the study and preservation of eggs and sperm who disclose their use of donated spermatozoa to their children.

Design: A questionnaire survey of couples who had a child using donated spermatozoa.

Setting: University hospital laboratory.

Patient(s): One hundred five couples.

Intervention(s): Questionnaire sent by mail.

Main Outcome Measure(s): The percentage of parents who disclose their use of donated spermatozoa to their child.

Result(s): Among the 157 questionnaires sent, 105 couples answered, which corresponded to 138 children. There were 40 (38%) couples who had already disclosed the donor origin to their child and 65 (62%) who had not. Of the 40 couples who disclosed the donor origin, 37 (93%) had intended to do so before making use of assisted reproductive techniques (ART), but two (5%) had not wanted to do so before ART. Among the 65 couples who did not inform their child, 42 (65%) planned to inform their child soon, but 20 (31%) wanted to keep the sperm origin secret. Of the 20 couples who wanted to keep the origin secret, nine couples had told other persons about the gamete donation but had not informed their child and do not intend to inform their child in the future.

Conclusion(s): This first report about disclosure attitude in a large cohort of parents of donor-conceived offspring in France showed that most parents had already disclosed their use of donated spermatozoa to their children or intended to disclose it soon and had an attitude after birth consistent with their intentions prior to ART.
