Uterotubare Transportstörung bei Adenomyose und Endometriose – Ursache der Infertilität
This paper investigates the role of uterotubal transport disorders, stemming from basal endometrial displacement, as a cause of infertility in patients with endometriosis and adenomyosis.

The paper studied women with laparoscopically confirmed endometriosis using T2-weighted uterine MRI to assess the subendometrial transition zone (JZ) and, in those with a desire for children, hysterosalpingoscintigraphy (HSSG) to evaluate periovulatory uterotubal sperm transport. It found that 62.5% (35/56) of women with endometriosis had a significantly widened JZ (11 mm vs 5 mm), with JZ widening >9 mm indicating adenomyosis, and that women with signs of adenomyosis had poorer HSSG results, with 66% (12/18) showing no periovulatory positive sperm transport (negative HSSG). In contrast, among women with endometriosis without radiologic adenomyosis signs, 88% (15/17) had intact uterotubal transport (positive HSSG), though 45% showed an unphysiological contralateral transport pattern; in controls, transport to the dominant follicle side occurred in 70% (negative HSSG in 15%), and negative HSSG corresponded to an estimated 90% exclusion of spontaneous pregnancy. The paper is centrally about endometriosis and adenomyosis — it links endometriosis-associated JZ changes to adenomyosis and uses uterotubal transport imaging to explain infertility mechanisms in this population.
