DOI: 10.1002/bies.202200039
Abstract: Sex reversal, a mismatch between phenotypic and genetic sex, can be induced by chemical and thermal insults in ectotherms. Therefore, climate change and environmental pollution may increase sex‐reversal frequency in wild populations, with wide‐ranging implications… read more here.

DOI: 10.1038/s41437-021-00406-z
Abstract: The view that has genotypic sex determination and environmental sex determination as mutually exclusive states in fishes and reptiles has been contradicted by the discovery that chromosomal sex and environmental influences can co-exist within the… read more here.

DOI: 10.1111/and.13585
Abstract: Testicular disorder of sex development (TDSD) is a rare condition, characterised by a female karyotype, male phenotype, small testes and cryptorchidism. Only a few studies have investigated the genetic causes of male sex reversal. This… read more here.

DOI: 10.1111/jfb.15241
Abstract: This study examined the changes in sex ratios and sex reversal rates in pejerrey Odontesthes bonariensis, that occur with the progression of the spawning season in a seminatural setting. Four groups of hatchery-produced pejerrey larvae… read more here.

DOI: 10.1111/mec.16404
Abstract: The sex of vertebrates is typically determined genetically, but reptile sex can also be determined by developmental temperature. In some reptiles, temperature interacts with genotype to reverse sex, potentially leading to transitions from a chromosomal… read more here.

DOI: 10.1126/sciadv.abk0275
Abstract: Sex determination and differentiation in reptiles are complex. In the model species, Pogona vitticeps, high incubation temperature can cause male to female sex reversal. To elucidate the epigenetic mechanisms of thermolabile sex, we used an… read more here.

DOI: 10.1242/bio.050054
Abstract: ABSTRACT The teleost fish, medaka (Oryzias latipes), employs the XX/XY genetic sex determination system. We show here that the phenotypic sex of medaka is affected by changes in lipid metabolism. Medaka larvae subjected to 5 days… read more here.

DOI: 10.1371/journal.pone.0173974
Abstract: Background The natural sex reversal severely affects the sex ratio and thus decreases the productivity of the rice field eel (Monopterus albus). How to understand and manipulate this process is one of the major issues… read more here.

Abstract: Sex determination in mammals is controlled by the dominance of either pro-testis (SRY-SOX9-FGF9) or pro-ovary (RSPO1-WNT4-FOXL2) genetic pathways during early gonad development in XY and XX embryos, respectively. We have previously shown that early, robust… read more here.
