This retrospective study found a 5.9% prevalence of congenital uterine anomalies in women with endometriosis, noting that those with both conditions were more likely to have severe endometriosis and dysmenorrhea.

The provided text does not contain the body of a biomedical research paper but rather a security warning from a website protection system called Anubis. This message explains that the site uses a Proof-of-Work scheme to prevent automated scraping by AI companies and requests users to disable certain browser plugins. Consequently, no study on endometriosis or congenital uterine malformations is available for summary. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.
Abstract
STUDY OBJECTIVE: The association between endometriosis and congenital uterine anomalies (CUAs) has been discussed for decades, but existing evidence about this association is scarce. Our study aimed to evaluate the prevalence of CUAs in women with endometriosis and to identify specific characteristics in women with both CUAs and endometriosis in a large cohort of patients.
DESIGN: This is a retrospective single-center observational study conducted between January 2006 and June 2021.
SETTING: Swiss tertiary hospital.
PATIENTS: Women with histologically confirmed endometriosis at laparoscopy.
INTERVENTIONS: All women included in this study underwent a preoperative 2-dimensional ultrasound by an experienced sonographer. In cases of suspected intrauterine pathology, bleeding disorders, or infertility, an additional hysteroscopy was performed.
MEASUREMENTS AND MAIN RESULTS: Of 1566 women with histologically confirmed endometriosis, 93 were diagnosed as having CUAs (5.9%). The most frequent malformations were U1c (arcuate uterus) (41 of 93, 44.1%), U2a (partial septate uterus) (19 of 93, 20.4%), U3b (complete bicorporeal uterus) (17 of 93, 18.3%), and U3a (partial bicorporeal uterus) (10 of 93, 10.8%). Women with both CUAs and endometriosis were more frequently diagnosed as having endometriosis revised American Society for Reproductive Medicine stage IV (p = .017) and presence of dysmenorrhea (p = .019) in comparison with women with endometriosis and a morphologically normal uterus.
CONCLUSIONS: To the best of our knowledge, this is the largest endometriosis population examined for the prevalence of CUAs. According to our findings, the prevalence of CUAs in women with endometriosis does not seem to be higher than in the general population. However, women with CUAs and endometriosis are more likely to have severe endometriosis (revised American Society for Reproductive Medicine stage IV) and dysmenorrhea than patients with endometriosis without CUA.

You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites. This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.
Anubis is a compromise. Anubis uses a Proof-of-Work scheme in the vein of Hashcash, a proposed proof-of-work scheme for reducing email spam. The idea is that at individual scales the additional load is ignorable, but at mass scraper levels it adds up and makes scraping much more expensive.
Ultimately, this is a placeholder solution so that more time can be spent on fingerprinting and identifying headless browsers (EG: via how they do font rendering) so that the challenge proof of work page doesn't need to be presented to users that are much more likely to be legitimate.
Please note that Anubis requires the use of modern JavaScript features that plugins like JShelter will disable. Please disable JShelter or other such plugins for this domain.
