Cross-species summary: Previously known as Sex reversal: XY female, SRY-negative. The present name (ovotesticular DSD) corresponds to the recommendations on nomenclature for disorders of sexual development (DSD) proposed by Lee et al. (Pediatrics 2006;118;e488; DOI: 10.1542/peds.2006-0738).

Species-specific name: sex-reversal

Species-specific description: Kurtz et al. (2021) "successfully generated a knockout of the porcine SRY gene by microinjection of two CRISPR-Cas ribonucleoproteins, targeting the centrally located "high mobility group" (HMG), followed by a frameshift mutation of the downstream SRY sequence. This resulted in the development of genetically male (XY) pigs with complete external and internal female genitalia, which, however, were significantly smaller than in 9-mo-old age-matched control females. Quantitative digital PCR analysis revealed a duplication of the SRY locus in Landrace pigs similar to the known palindromic duplication in Duroc breeds. Our study demonstrates the central role of the HMG domain in the SRY gene in male porcine sex determination." These animals are considered genetically-modified organisms (GMO).
