Full-sibling embryos created by anonymous gamete donation in unrelated recipients

The otherwise informative paper “Full-sibling embryos created by anonymous gamete donation in unrelated recipients” by Dicken et al. (1) was marred by use of limited evidence to support the claim that “most parents conceiving with the assistance of donor gametes do not disclose the nature of their conception to their resulting offspring.” A more thorough review of available literature than the two cited sources (2,3) reveals a more nuanced picture, as indicated by several European studies.
