Corrigendum to "ART in Latin America: The Latin American Registry, 2020" [JBRA Assist Reprod. 2023;27(3):514-538].

In 2020, for the first time, collaborating institutions were asked to describe the type of endometriosis when this was part of a primary or secondary diagnosis. This included how the diagnosis was reached, and when reached surgically (mostly laparoscopic), centers were asked to describe the type of surgery performed, classified into five categories: peritoneal fulguration, cystectomy, or drainage of endometrioma, deep infiltration, partial oophorectomy and a combination of the above. Endometriosis was diagnosed by direct visualization in 753 out of 39,418 initiated cycles (1.9%). The number of oocytes collected as well as the delivery rate, stratified by age, were compared in women having endometriosis either as a primary or secondary diagnosis, excluding freeze-all cycles, and women having tubal and/or endocrine factors, excluding ovarian insufficiency. As seen in Supplementary Table 7, in spite of the fact that the number of eggs recovered in cases with endometriosis was significantly lower at all ages the delivery rates appeared to be higher in women with endometriosis compared with women with tubal or endocrine factors, although the difference was not statistically significant. These findings follow a similar direction of a study by Opøien et al. (2011) who showed better ART outcomes in minimal or mild endometriosis after surgical removal of endometriotic tissue; and a review by Senapati et al. (2016), using the SART database, showing, that in the absence of comorbidity, endometriosis yields fewer oocytes but higher pregnancy and delivery rates. The authors would like to apologize for any inconvenience caused.
