Biological Parenthood in Relation to Future Artificial Reproductive Technologies : A Scoping Review of Definitions.
Article in Journal of bioethical inquiry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Future artificial reproductive technologies, including mitochondrial replacement therapy, in vitro gametogenesis, and ectogenesis raise important legal and ethical questions, such as: Who should be considered the parents of children born from these technologies? The concept of biological parenthood is commonly used as a basis for answering this question. Therefore, this study assesses the use and meaning of biological parenthood in relation to these future artificial reproductive technologies. Searches were conducted in six databases, including PubMed, PsycINFO, Web of Science, HeinOnline, Westlaw Classic, and Philosopher's Index. Articles were included only if they met one of the following conditions: 1) a definition of biological parenthood, 2) a definition of genetic parenthood, 3) a definition of gestational parenthood, 4) a definition of biological, genetic, or gestational parenthood combined with either mitochondrial replacement therapy, in vitro gametogenesis, or ectogenesis. Of the 6,304 studies retrieved, 131 results were included for analysis. The review found multiple meanings of biological parenthood, encompassing different biological ties (genetic, gestational, and postnatal) and diverse conceptual methods of interpreting its meaning. The definition of gestational parenthood appears to be less univocal than the term initially suggests, and that of genetic parenthood has evolved. The lack of consensus on the meaning and definition of biological parenthood leads to inconsistent determinations of biological parenthood in relation to future artificial reproductive technologies. This raises serious doubts about whether biological parenthood can continue to play the fundamental role in ethical and legal perspectives on parenthood that it has held for a long time.
