Abstract
Study objective:
The aim of this study was to characterise the severity of adenomyosis on MRI in infertile women, and to assess if MRI characteristics of adenomyosis severity are associated with worse IVF/ICSI pregnancy outcomes versus male infertility controls.
Materials and methods:
This single-centre retrospective study was carried out at Catharina Hospital in Eindhoven, The Netherlands. The MRIs of 124 infertile women undergoing their first, fresh embryo transfer during IVF/ICSI, diagnosed with adenomyosis only (
Results:
Patients with adenomyosis had significantly worse IVF/ICSI outcomes compared to male infertility controls. When assessing individual MRI parameters, adenomyosis patients with a mean junctional zone (JZ) of >12 mm, a JZ/Myometrium ratio of >40%, presence of myometrial cysts and presence of endometriosis (specifically deep invasive endometriosis(DIE)) showed statistically significantly worse outcomes compared to patients with milder disease.
Conclusion:
The results of this retrospective study suggest that individual MRI markers for severe adenomyosis (mean JZ > 12 mm, myometrial cysts), especially when combined with (severe) endometriosis, may be associated with fewer pregnancies during IVF/ICSI when compared to male infertility controls. Future prospective studies should investigate the prognostic potential of these markers for prediction of IVF/ICSI success.
