WHERE ARE THE DONORS: DO DONOR CONCEIVED PEOPLE BECOME DONORS THEMSELVES?

      Objective

      Assisted reproductive technologies (ART) using donor gametes has become more common over recent decades, and allows the opportunity for family building for many people that would otherwise be unable to conceive. We seek to determine if donor-conceived people (DCP) are likely to be donors themselves.

      Materials and Methods

      A 31 question survey was distributed to adult DCP of the Donor Sibling Registry (DSR). Included in the survey were questions whether DCP had ever donated sperm, oocytes, or embryos. Bivariate statistics were used to compare DCP who became donors versus those who did not.

      Results

      529 people completed the survey. Overall, there was a low rate of donors amongst the respondents with only 10 (1.9%) of DCP having already donated sperm, oocytes, or embryos. DCP who were donors tended to be older (median (range): 34.5(20-61) v. 28 (18-77);p=0.09) and less likely to be female (60.0% v. 82.1%;p=0.09). DCP who became donors had similar education level and parity compared to non-donors (Table). DCPs perception regarding being donor-conceived did not factor into the likelihood of being a donor themselves, with 70% of donors having overall neutral/positive feelings regarding their donor-conceived status vs 78.8% non-donors having the same feelings (p=0.45). DCPs who were donors tended to be less likely to have an ongoing relationship with the donor who they were conceived from (50% vs 82.5%; p=0.16), but were no more likely to have an ongoing relationship with a half sibling(s) from the same donor (85.7% vs 75.4%; p=1.00). Time of life when people found they were donor-conceived did not differ between donors and non-donors (70% vs 63.3%; p=0.75).

      Conclusions

      Overall, DCP are not likely to become donors themselves, and having an overall positive experience being donor-conceived did not affect this decision. Trends reveal that DCP who become donors are slightly older, less likely to be female, and less likely to have an ongoing relationship with the donor they were conceived from compared to DCP who were non-donors.

      Impact Statement

      This is the first study to evaluate the whether being a DCP impacts the decision of becoming a donor themselves. There is a low rate of DCP who become donors which warrants further investigation.
