Endometriosis diagnosed by ultrasound is associated with lower live birth rates in women undergoing their first IVF/ICSI treatment

• ObjectiveTo study the cumulative live birth rate (CLBR) after the first in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment in women with or without deep-infiltrating endometriosis (DIE) and/or endometrioma diagnosed by transvaginal ultrasonography (TVUS), using the International Deep Endometriosis Analysis (IDEA) group definitions.DesignProspective observational cohort study at a university hospital.Patients(s)In total, 1,040 women with subfertility aged 25 to ≤39 years were undergoing their first IVF/ICSI treatment between January 2019 and October 2022. Of these, 234 (22.5%; 95% confidence interval [CI], 20.0–25.0) women were diagnosed with DIE and/or endometrioma at systematic TVUS before starting their treatment.Intervention(s)All women underwent their first IVF or ICSI treatment. Fresh and/or frozen embryos from the first cycle were used until pregnancy was achieved or no embryos remained.Main Outcome Measure(s)Cumulative live birth rate after the first IVF/ICSI cycle in women with or without DIE and/or endometrioma.Result(s)The CLBR after the first IVF/ICSI treatment in the total cohort of women was 426/1,040 (41.0%; 95% CI, 38.0–44.0). Women with DIE and/or endometrioma had a lower CLBR (78/234, 33.3%; 95% CI, 27.3–39.4) than women without the disease (348/806, 43.2%; 95% CI, 39.8–46.6). The crude relative risk (RR) for cumulative live birth for women with DIE and/or endometrioma was 0.77; 95% CI, 0.63–0.94, and after adjustments were made for age, body mass index, s-antimüllerian hormone, stimulation protocol, and day for embryo transfer, the adjusted RR was 0.63; 95% CI, 0.48–0.82. There was no difference in the number of retrieved mature oocytes, fertilization rate, or good quality embryos between the 2 groups.ConclusionThe presence of DIE and/or endometrioma diagnosed by TVUS lowers the chance of live birth in women undergoing their first IVF/ICSI treatment.
