  • Endometriosis diagnosed by ultrasound is associated with lower live birth rates in women undergoing their first IVF/ICSI treatment
  • Ingår i: Fertility and Sterility. - 1556-5653.
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Prevalence of adenomyosis features in women scheduled for assisted reproductive treatment, using the Morphological Uterus Sonographic Assessment group definitions
  • Ingår i: Acta Obstetricia et Gynecologica Scandinavica. - 1600-0412.
  • Tidskriftsartikel (refereegranskat)abstract
    • IntroductionStudies that use standardized ultrasonographic criteria to diagnose adenomyosis in subfertile women are needed. These would improve the understanding of the disease burden and enable further studies on its impact on fertility and assisted reproductive treatment (ART) outcome. The aim of this study was to determine the prevalence of different features of adenomyosis in women scheduled for their first ART, diagnosed at two (2D) and three-dimensional (3D) transvaginal ultrasonography (TVUS) using the revised Morphological Uterus Sonographic Assessment (MUSA) group definitions.Material and methodsThis was a prospective, observational cross-sectional study of subfertile women aged 25 to ≤39 years, that were referred to a university hospital for their first ART between December 2018 and May 2021. Of 1224 eligible women, 1160 women fulfilled the inclusion criteria and consented to participate in the study. All women underwent a systematic 2D and 3D TVUS examination. The primary outcome was the presence of direct and indirect features of adenomyosis, as proposed by the MUSA group. Secondary outcomes were to describe the ultrasonographic characteristics of the different features, as well as any difference in the diagnostics at 2D or 3D TVUS and any association with clinical characteristics such as endometriosis.ResultsAt least one direct or indirect feature of adenomyosis was observed in 272 (23.4%, 95% confidence interval [CI] 21.0–25.9) women. Direct features that are pathognomonic for the disease were observed in 111 (9.6%, 95% CI, 7.9–11.3) women. Direct features were visible only at 3D TVUS in 56 (4.8%, 95% CI 3.6–6.1) women, that is, 56/111 (50.5%) of women with at least one direct adenomyosis feature. Direct features were more common in women with endometriosis (OR 2.8, 95% CI 1.8–4.3).ConclusionsWe found than one in 10 women scheduled for ART had direct features of adenomyosis at ultrasound examination. The present study suggests that the use of 3D TVUS is an important complement to 2D in the diagnostics of adenomyosis. Our results may further improve the counseling of women scheduled for ART and enables future studies on the impact of different features of adenomyosis on subfertility, ART results and obstetric outcomes.

  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To estimate the prevalence of endometrioma and deep infiltrating endometriosis (DIE), assessed by systematic transvaginal ultrasound examination, in women with subfertility accepted for their first assisted reproductive treatment and to describe the prevalence of endometriotic lesions in different anatomical locations of the pelvis. Design: Cross-sectional study. Setting: Reproductive Medicine Center, Department of Obstetrics and Gynecology, University hospital. Patient(s): A total of 1,191 women with subfertility aged 25–39 years accepted for their first assisted reproductive treatment between December 2018 and May 2021. Intervention(s): All women underwent a systematic transvaginal ultrasound examination. The endometriotic lesions visible on ultrasound examination were described according to the International Deep Endometriosis Analysis group consensus opinion for systematic approach to assess endometriotic lesions. Main Outcome Measure(s): Prevalence of endometrioma and DIE in women with subfertility and prevalence of endometriotic lesions in various anatomical locations of the pelvis. Result(s): Endometriosis prevalence was 21.8%, with endometriotic lesions found in 260 of the 1,191 women. Overall, 125 (10.5%) women had endometrioma and 205 (17.2%) women had DIE. Of these 260 women, 197 (75.8% of women with endometriosis) did not have any previous knowledge about having endometriosis. The most common location for endometriotic lesions was the uterosacral ligaments, with lesions found in 151 (12.7%) of all women. The second most common location was the ovaries containing endometrioma, found in 125 (10.5%) women. Most women had 1 (n = 121, 10.2%) or 2 (n = 82, 6.9%) endometriotic lesions. Conclusion(s): The prevalence of endometrioma and DIE in women with subfertility, diagnosed by systematic transvaginal ultrasound examination, was 21.8%. Of these, three-fourth of women had no knowledge about the presence of disease.

  • Anti-müllerian hormone levels are associated with live birth rates in ART, but the predictive ability of anti-müllerian hormone is modest
  • 2018
  • Ingår i: European Journal of Obstetrics, Gynecology, and Reproductive Biology. - : Elsevier BV. - 0301-2115. ; 225, s. 199-204
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: The aim was to evaluate the association between serum Anti-Müllerian Hormone (AMH) level and cumulative live birth rates (LBR) in patients undergoing their first in vitro fertilization (IVF) treatment cycle, and to compare serum AMH levels with Antral Follicle Count (AFC) and Ovarian Sensitivity Index (OSI) as predictors of live birth. Study design: A prospective cohort study of 454 patients under the age of 40 and with a regular menstrual cycle of 21-35 days, undergoing their first IVF treatment cycles between September 2010 and June 2015. Participants were divided into three groups based on their AMH level, (AMH ≤10, AMH 10-<30 and AMH ≥30 pmol/l). Any difference in AMH-distribution between patients with or without live birth was analyzed using a Mann-Whitney-test, and live birth rates were compared between groups by a chi-squared test for linear trend. The ability of AMH, OSI and AFC as predictors of live birth was assessed by a receiver operating characteristics-analysis and the area under the curve (AUC) was calculated. Results: Patients with live birth had a higher AMH, median (range) 26 [0-137] pmol/l, compared with patients without live birth, AMH 22 [0-154] pmol/l, p = 0.035. Mean live birth rate (SD) was 0.36 (0.48) in the total cohort, 0.26 (0.44) in AMH-group <10, 0.34 (0.48) in AMH-group 10-<30, and 0.41(0.49) in AMH-group ≥30. Thus live birth rates increased with 8% per AMH-group (95% CI: 0.02 −0.14, p = 0.015). The AUC for AFC was 0.56, for AMH 0.57 and for OSI 0.63, respectively. Conclusion: AMH concentration in serum is associated with live birth rates after IVF. Our results suggest that both AMH, AFC and OSI have an equal but modest predictive ability in relation to live birth rate.

  • Interaction between serum levels of Anti-Mullerian Hormone and the degree of sperm DNA fragmentation measured by sperm chromatin structure assay can be a predictor for the outcome of standard in vitro fertilization
  • 2019
  • Ingår i: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 14:8
  • Tidskriftsartikel (refereegranskat)abstract
    • Serum levels of Anti-Mullerian Hormone (AMH) have been shown to be biomarker for prediction of the quantitative aspects of ovarian reserve. On the male side, sperm chromatin structure assay (SCSA) DNA fragmentation index (DFI) has been demonstrated to be an important predictor of outcomes in standard IVF procedures but to less degree in intracytoplasmic sperm injection procedures (ICSI). The purpose of this study was to investigate whether the combination of female AMH serum levels and sperm DFI adds to prediction of the outcome of assisted reproduction. A total of 352 couples was included (ICSI-148: IVF-204) A venous blood sample was drawn for AMH analysis before IVF/ICSI treatment. DFI was measured in the ejaculate used for assisted reproduction. Regression models for the following odds ratio calculations were constructed: for obtaining at least one Good Quality Embryo; for live birth in all procedures; for pregnancy in procedures where embryo transfer was performed; for miscarriage. For DFI increase by 10 percentage points (not increased DFI as reference) odds ratio for Good Quality Embryo was statistically significantly lower when AMH was at lower quartile (AMH <12 pmol/L; OR = 0.29, 95% CI: 0.14-0.59,) but not when AMH was at upper quartile (AMH ≥ 36 pmol/L; OR = 0.95, 95% CI: 0.43-2.13,). The marginal effect of an increase in DFI by 10 percentage points was statistically significant only when AMH < 25.2 pmol/L. Similar results were obtained as considers live birth following standard IVF. No interactions were seen for standard IVF in relation to the risk of miscarriage and for any of the outcomes when ICSI was used as method of treatment. We conclude that the impact of high DFI on the outcome of standard IVF is most pronounced if the female partner has relatively low AMH levels. This finding may help in defining the role of sperm DNA integrity testing in management of infertile couples. It may also explain some of the heterogeneity in results of studies focusing on predictive value of DFI measurements in assisted reproduction.
