To do so, method unification, transparency, biobanking, and robust clinical phenotyping of patient-derived samples will be necessary to fully leverage organoids as a powerful resource for advancing the gynaecological field and reproductive biology. Specifically for endometriosis, organoids offer an unprecedented opportunity to study this complex... See more

rganoids are a promising innovative tool to investigate the mechanistic features of endometriotic aetiology and advance the identification of potential novel therapeutic targets to treat those whose lives are compromised by endometriosis.

Endometriosis remains one of the most poorly understood conditions due to its molecular, hormonal, cellular, and heterogeneric complexity, and an overall lack of funding for research into female-only diseases (Smith, 2023; Zondervan et al. , 2023).

Primary endometrial epithelial cells cultured on hard plastic (i.e. polystyrene) dishes rapidly undergo de-differentiation (Zhou et al. , 2022) and, in the presence of serum, further lose physiological attributes (Ghosh and Sengupta, 1995) and epithelial barrier integrity, and have increased cellular senescence by the third cell passage (Arnold et...

The lack of menstrual shedding and the immune differences in animal models of endometriosis limit the translational potential to human applications.

While animal models of endometriosis are important to study the establishment, progression, and regression of endometriosis via the surgical induction of disease (Bruner et al. , 1995; Grümmer, 2012; Burns et al. , 2025; Dodds et al. , 2025; Hull et al. , 2025), most of these experimental animals do not naturally develop this disease and limit...

ndometriosis lesions are complex multicellular tissue deposits composed of endometrial-like stromal cells with or without epithelial cells or glands embedded within a microenvironment of extracellular matrix, fibrosis, scarring, and sometimes haemorrhage (Clement, 2007; Vigano et al. , 2018). Additionally, lesions are infiltrated by blood vessels,... See more

The overwhelming prevalence of endometriosis and the unknown aeteology highlight the need for a better understanding of the basic biology of endometriosis formation and persistence to enable subsequent identification of targets for effective therapies for endometriosis.

here is no known cure, and treatments are associated with low long-term success rates and significant side effects (Johnson et al. , 2013).
