Analysis of factors affecting pregnancy rate after laparoscopic surgery for infertility associated with endometriosis.

OBJECTIVE: To analyze the factors that might influence the pregnancy rate in patients with infertility related to endometriosis (EMs) after undergoing laparoscopic surgery, providing guidance for our clinical diagnostic and therapeutic decision-making. METHODS: A retrospective analysis was conducted on clinical records and 1-year postoperative pregnancy outcomes of 335 patients diagnosed with endometriosis-related infertility via laparoscopic surgery, admitted to our department from January 2018 to December 2020. RESULTS: The overall pregnancy rate for patients with endometriosis (EMs) related infertility 1-year post-surgery was 57.3 %, with the highest pregnancy rate observed between 3 to 6 months after surgery. Factors such as Body Mass Index (BMI) (P = 0.515), presence of dysmenorrhea (P = 0.515), previous pelvic surgery (P = 0.247), type of EMs pathology (P = 0.893), and preoperative result of serum carbohydrate antigen 125 (CA125)（P = 0.615）had no statistically significant effect on postoperative pregnancy rates. The duration of infertility (P = 0.029), coexistence of adenomyosis (P = 0.042), surgery duration (P = 0.015), intraoperative blood loss (P = 0.050), preoperative result of serum anti-Müllerian hormone (AMH) (P = 0.002) and age greater than 35 (P = 0.000) significantly impacted postoperative pregnancy rates. The post-surgery pregnancy rate in patients with mild (Stage I-II) EMs was notably higher than those with moderate to severe (Stage III-IV) EMs (P = 0.009). Age (P = 0.002), EMs stage (P = 0.018), intraoperative blood loss (P = 0.010) and adenomyosis (P = 0.022) were the factors that affected the postoperative live birth rate. CONCLUSION: For patients with EMs-related infertility undergoing laparoscopic surgery, factors such as age > 35 years, infertility duration > 3 years, concurrent adenomyosis, severe EMs, surgery duration ≥ 2 h, intraoperative blood loss ≥ 50 ml, and low AMH before surgery are detrimental for the pregnancy rate within the first postoperative year. However, BMI, dysmenorrhea, past history of pelvic surgery, EMs pathology types (ovarian, peritoneal, deep infiltrating),and preoperative result of serum CA125 barely show any statistical difference in their effect on postoperative pregnancy rates. In terms of postoperative live birth rate, age > 35 years, severe EMs, intraoperative blood loss ≥ 50 ml, and adenomyosis were adverse factors.

First-line surgery versus first-line assisted reproductive technology for women with deep infiltrating endometriosis: a systematic review and meta-analysis.

Background: The efficiency of different first-line treatments, such as first-line surgery and assisted reproductive technology (ART), in women with deep infiltrating endometriosis (DIE) is still unclear due to a lack of direct comparative trials. This systematic review and meta-analysis aim to elucidate and compare the efficacies of first-line treatments in patients with DIE, with an emphasis on fertility outcomes. Methods: An exhaustive search of PubMed Central, SCOPUS, EMBASE, MEDLINE, Cochrane trial registry, Google Scholar, and Clinicaltrials.gov databases was done to identify studies directly comparing first-line surgery and assisted reproductive technology (ART) for DIE, and reporting fertility-related outcomes. Pooled estimates for each of the binary outcomes were reported as odds ratios (ORs) with 95% confidence intervals (CIs). The results were pooled using a random-effects model with the Mantel-Haenszel technique. Results: Our results show that pregnancy rate per patient (OR, 1.47; 95% CI, 0.59 to 3.63), pregnancy rate per cycle (OR, 1.16; 95% CI, 0.45 to 2.99), and live births per patient (OR, 1.66; 95% CI, 0.56 to 4.91) were comparable in DIE patients, treated with surgery or ART as a first line of treatment. When both complete and incomplete surgical DIE excision procedures were taken into account, surgery was associated with a significant enhancement in the pregnancy rate per patient (OR, 1.63; 95% CI, 1.11 to 2.40). Conclusion: The available evidence suggests that both first-line surgery and ART can be effective DIE treatments with similar fertility outcomes. However, further analysis reveals that excluding studies involving endometriomas significantly alters the understanding of treatment efficacy between surgery and ART for DIE-associated infertility.

Effects of hysteroscopic septum incision versus expectant management on IVF outcomes in women with complete septate uterus: a retrospective study.

OBJECTIVE: This retrospective study aimed to assess the impact of hysteroscopic septum incision on in vitro fertilization (IVF) outcomes among infertile women diagnosed with a complete septate uterus and no history of recurrent pregnancy loss. METHODS: The study was conducted at a tertiary reproductive center affiliated with a university hospital and involved 78 women with a complete septate uterus. Among them, 34 women underwent hysteroscopic septum incision, while 44 women opted for expectant management. The primary outcome measure was the live birth rate, while secondary outcomes included clinical pregnancy rate, preterm birth rate, miscarriage rate, and ongoing pregnancy rate. RESULTS: Women who underwent hysteroscopic septum incision demonstrated a comparable likelihood of achieving a live birth compared to those managed expectantly (25% vs. 25%, Relative Risk (RR): 1.000, 95% Confidence Interval (CI): 0.822 to 1.216). No preterm births occurred in either group. The clinical pregnancy rate, ongoing pregnancy rate, and miscarriage rate showed no significant differences between the surgical group and the expectant management group. Subgroup analyses based on the type of embryo transferred also revealed no significant differences in outcomes. CONCLUSIONS: Hysteroscopic septum incision does not appear to yield improved IVF outcomes compared to expectant management in infertile women with a complete septate uterus and no history of recurrent pregnancy loss.

Laparoscopic transfundal approach to cervical dilation: a novel treatment for cervical stenosis and cervical factor infertility.

OBJECTIVE: To demonstrate a novel technique used to restore cervical patency in a patient with severe iatrogenic cervical stenosis. DESIGN: Surgical video case report. SETTING: A single academic institution. PATIENT(S): We highlight the case of a 35-year-old nulliparous woman with a history of primary infertility. Her past medical history was significant for focal, invasive, well-differentiated squamous cell carcinoma of the cervix, for which she underwent a loop electrosurgical excision procedure. During her infertility assessment, she was found to have an extremely stenotic cervix that was refractory to conventional treatment options. INTERVENTIONS: This video highlights our innovative laparoscopic transfundal technique used to restore her cervical patency. MAIN OUTCOME MEASURES: None, as this is a descriptive case report. RESULTS: Postoperatively, the patient had continued cervical patency for >1 year with successful fertility treatment resulting in pregnancy. CONCLUSIONS: To our knowledge, this is the first case report describing a laparoscopic transfundal approach used to reestablish cervical patency. This approach may be considered for patients with cervical stenosis who have not responded to standard conservative therapies.

Impact of Endometriosis Surgery on In Vitro Fertilization/Intracytoplasmic Sperm Injection Outcomes: a Systematic Review and Meta-analysis.

Endometriosis-related infertility remains a therapeutic challenge. A burning issue in this field of research is determining whether pre-assisted reproductive technology (ART) surgery may be of some benefit in terms of reproductive outcomes. This systematic review and meta-analysis aimed at comparing ongoing pregnancy rates (OPR) and/or live birth rates (LBR) in patients who underwent endometriosis surgery before ART (IVF/ICSI) in comparison with patients who underwent first-line ART (IVF/ICSI). Searches were conducted from January 1990 to June 2021 on PubMed, Embase, and Cochrane Library using the following search terms: endometriosis, surgery, reproductive outcomes, and IVF/ICSI. The primary outcomes were OPR or LBR. A total of 19 studies were included in the meta-analysis. No statistically significant differences in LBR [0.91[0.63, 1.30]; I2 = 66%; n = 11], OPR [1.28[0.66, 2.49]; I2 = 60%; n = 3], and early pregnancy loss rate [0.88[0.62, 1.25]; I2 = 0%; n = 7] per cycle were found when comparing patients who underwent endometriosis surgery before IVF/ICSI and those who did not. After the exclusion of the studies with high risks of bias, the LBR per cycle was significantly reduced in the case of surgical treatment before IVF/ICSI [0.53[0.33, 0.86]; I2 = 30%; n = 4]. These data urge the clinician to carefully weigh the pros and cons before referring infertile patients with endometriosis to surgery before IVF, highlighting the key role of multidisciplinary referral centers.

Surgical treatment of deep endometriosis: Impact on spontaneous conception.

Deep endometriosis (DE) is the most severe form of endometriosis and is commonly associated with infertility. Surgical treatment of DE appears to increase chances of spontaneous conception in appropriately selected patients wishing to conceive. Identifying, however, the exact impact of DE, and its surgical removal, on natural conception is highly challenging. The surgical approach should be favoured in symptomatic patients with pregnancy intention. Limited data from infertile patients suggest that outcomes may not differ from patients without known infertility. Complex DE surgery carries a risk of serious complications, therefore, it should be performed in centers of expertise. Such complications may, however, not have a significant negative impact on fertility outcomes, according to limited available data. Data on obstetric outcomes of spontaneous conceptions after DE surgery are too scarce. In asymptomatic, infertile patients the debate between primary surgery or Artifial Reproductive Technology is ongoing, until randomized studies report their results.

Discoid excision for colorectal endometriosis associated infertility: A balance between fertility outcomes and complication rates.

OBJECTIVE: The objective of our study was to study the impact of discoid excision for deep endometriosis (DE) with colorectal involvement on fertility outcomes. METHODS: 49 patients with a desire for pregnancy treated with discoid excision for colorectal endometriosis in our endometriosis expert center between January 2015 and August 2020 were selected from our prospectively maintained database. Indications for surgery were either infertility and / or pelvic pain. Postoperative complications were graded according to the Clavien-Dindo classification. Fertility outcomes, both spontaneous and post-ART pregnancies, were analyzed. RESULTS: Among the 49 patients who underwent discoid excision exclusively (no other digestive resection) with a desire to conceive, 25 had a pregnancy after surgery and 24 did not. Double discoid excision was performed in 6.1 % of the cases (3/49). A colpectomy was performed in 12.2 % of the patients (6/49), and a protective stoma in 12.2 % (6/49). Fenestration of endometriomas was performed in 28.6 % of the patients (14/49), and parametrectomy in 40.8 % (20/49). The postoperative complication rate was 24.5 % (12/49) including 10.2 % (5/49) grade I, 12.2 % (6/49) grade II, and 2 % (1/49) grade III. Prior to surgery, 28 (57.1 %) patients had infertility including 13 (52 %) that successfully conceived following surgery and 15 (62.5 %) that remain infertile. Spontaneous pregnancy was achieved in 60 % (15/25) of infertile patients' prior surgery. The live-birth rate in patients conceiving spontaneously was 75 % (12/16). CONCLUSION: Our results support that discoid excision is safe and associated with good fertility outcomes. Whether first-line surgery using discoid excision is superior to first-line ART remains to be determined.

Fertility, pregnancy and perioperative outcomes after operative hysteroscopy for uterine septum: a network meta-analysis.

INTRODUCTION: Septate uterus is a congenital malformation associated with adverse reproductive and pregnancy outcomes. It remains controversial whether hysteroscopic septoplasty should be recommended for the treatment of septate uterus, and it is also unclear if different hysteroscopic methods have more favorable outcomes. This study aims to compare the available hysteroscopic techniques of septoplasty for fertility, reproductive, and perioperative outcomes. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. We searched Medline, Scopus, and Cochrane databases up to April 2023 without language restrictions. Eligible studies had to compare two or more different methods of hysteroscopic septoplasty in women with septate uterus and report on fertility and pregnancy outcomes after a follow-up. Perioperative outcomes were also examined. Data extraction was performed by two independent reviewers using a standardized form. Risk of bias was assessed using the Newcastle-Ottawa Quality Assessment Form and Revised Cochrane risk-of-bias tool (RoB 2). RESULTS: Out of 561 studies identified, 9 were included in the systematic review and meta-analysis. The comparison of different hysteroscopic septoplasty techniques based on the energy used showed higher pregnancy rates after mechanical septoplasty in comparison to electrosurgery, while miscarriage and live birth rates were comparable. Laser vs. electrosurgery and mechanical techniques of septoplasty had comparable pregnancy, miscarriage, and live birth rates. The network meta-analysis after comparing every different method used showed significantly higher clinical pregnancy rate in scissor group in comparison to resectoscope. No significant differences were found among the techniques regarding miscarriage rate and live birth rate. CONCLUSION: In summary, this systematic review and network meta-analysis suggests that hysteroscopic septoplasty with scissors is associated with higher pregnancy rates compared to resectoscope. However, the limited evidence available and small sample sizes in the included studies indicate that these findings should be interpreted with caution. Further studies are required to determine the effectiveness of various hysteroscopic techniques and guide clinical decision-making in the management of this condition.

Miracles of science: Birth after uterus transplantation.

AIM: The concept of regaining childbearing ability via uterus transplantation (UTx) motivates many infertile women to pursue giving birth to their own children. This article provides insight into maternal and neonatal outcomes of the procedure globally and facilitates quality of care in related medical fields. METHODS: The authors searched ISI Web of Science, MEDLINE, non-PubMed-indexed journals, and common search engines to identify peer-review publications and unpublished sources in scientific reference databases. RESULTS: The feasibility of the procedure has been proven with 46 healthy children in 88 procedures so far. Success relies upon dedicated teamwork involving transplantation surgery, obstetrics and reproductive medicine, neonatology, pediatrics, psychology, and bioethics. However, challenges exist owing to donor, recipient, and fetus. Fetal growth in genetically foreign uterine allograft with altered feto-maternal interface and vascular anatomy, immunosuppressive exposure, lack of graft innervation leading to "unable-to-feel" uterine contractions and conception via assisted reproductive technology create notable risks during pregnancy. Significant portion of women are complicated by at least one or more obstetric problems. Preeclampsia, gestational hypertension and diabetes mellitus, elevated kidney indices, and preterm delivery are common complications. CONCLUSIONS: UTx has short- and long-term satisfying outcome. Advancements in the post-transplant management would undoubtedly lead this experimental procedure into mainstream clinical practice in the near future. However, both women and children of UTx need special consideration due to prematurity-related neonatal problems and the long-term effects of transplant pregnancy. Notable health risks for the recipient and fetus should be discussed with potential candidates for UTx.

The impact of metabolic surgery on natural conception rates in women with infertility, obesity and polycystic ovary syndrome: a retrospective study.

BACKGROUND: Women with obesity and polycystic ovary syndrome (OPOS) are at high risk for infertility. However, the reproductive effects of metabolic surgery on women with infertility and OPOS have not been fully elucidated. OBJECTIVES: We investigated the natural conception rates after metabolic surgery, and the variables associated with infertility in women with OPOS. SETTING: Shanghai Sixth People's Hospital, Shanghai, China. METHODS: This study included 72 women with infertility and OPOS who underwent metabolic surgery and were followed up for 4 years after surgery. Finally, 54 patients completed the study. Reproductive outcomes were assessed, along with changes in anthropometric parameters and metabolic indices before and 1 year after surgery (prepregnancy). Logistic regression analysis was used to identify variables influencing natural conception and delivery outcomes. RESULTS: After metabolic surgery, 35 patients (64.8%) became pregnant naturally, while 16 were still unable to conceive naturally. Preoperative body mass index (BMI) tended to be lower in the natural conception group than in the no natural conception group (38.9 ± 6.9 versus 43.6 ± 11.0 kg/m2, P = .070) and there were no significant differences in weight loss between the 2 groups after surgery. Logistic regression analysis showed that the BMI 1 year after surgery (prepregnancy) was an independent predictor of natural conception, and receiver operating characteristic analysis showed that a BMI of 27.0 kg/m2 was the optimal cutoff for predicting successful natural conception after surgery. CONCLUSIONS: Metabolic surgery can improve fertility in women with OPOS. Patients with a BMI < 27.0 kg/m2 1 year after surgery (prepregnancy) are more likely to become pregnant naturally and give birth.

INvestigational Study Into Transplantation of the Uterus (INSITU): a cross-sectional survey among women with uterine factor infertility in the UK assessing background, motivations and suitability.

IMPORTANCE: The study summarises the selection prescreen criteria currently used in the UK for a uterus transplant and highlights the number of women who are suitable to proceed. OBJECTIVES: To assess the demographics, motivations, reasons and suitability among women with absolute uterine factor infertility (AUFI) to undergo uterine transplantation (UTx). DESIGN: A cross-sectional survey. SETTING: An electronic questionnaire was sent via email to women with AUFI who had previously been referred to the UTx research team or approached the Womb Transplant UK Charity. The questions assessed suitability to undergo UTx based on demographic information, perceptions to adoption and surrogacy and reasons why UTx was preferable. Responses were assessed against the study selection criteria. PARTICIPANTS: Women with AUFI. RESULTS: 210 women completed the questionnaire. The most common aetiology of AUFI in our cohort was Mayer-Rokitansky-Küster-Hauser (68%; n=143) whereas 29% (n=62) had previously undergone hysterectomy. 63% (n=132) of the cohort had previously considered adoption, 5% (n=11) had attempted it and 2 (1%) had successfully adopted. The most common reason cited to undergo UTx over adoption was to experience gestation (n=63; 53%), while 37% (n=44) wanted a biologically related child. 76% (n=160) of participants had previously considered surrogacy, 22 (10%) had attempted it and 2 (1%) had successfully become mothers using a surrogate. The most common reason to undergo UTx over surrogacy was to experience gestation (n=77; 54%). 15% (n=21) were concerned about the legal implications, 14% (n=20) identified the financial cost as a barrier and 8% (n=12) could not consider it due to religious reasons. On adhering to the selection criteria, 65 (31%) women were suitable to proceed with the trial. CONCLUSION: The study demonstrates that implementing commonly used selection criteria for a UTx led to an attrition rate of more than two-thirds of women who requested to initially undergo the process. As more studies present outcomes following UTx, critical assessment of the selection criteria currently used is warranted to ensure potential recipients are not being unnecessarily excluded. TRIAL REGISTRATION NUMBER: NCT02388802.

Reproductive Surgery in Females with Obesity: Reproductive Consequences of Obesity and Applications for Surgical Care.

Obesity is the most common medical problem in women of reproductive age. The surgical applications for this population, many of who are interested in current or future fertility, are critical to safe and effective evaluation and management of issues that impact the reproductive system. As rates of obesity continue to rise worldwide, it is projected that one in two individuals will have obesity by 2030 leading to increasing numbers of individuals affected by a disease process that has implications for their gynecologic surgical care, fertility-related assessment, and infertility treatment. Offering patients with obesity access to safe reproductive surgery is a cornerstone of reproductive autonomy. This review will summarize current recommendations regarding surgical concepts for the operating room, office hysteroscopy, oocyte retrieval, and embryo transfer in female patients with obesity.

The effect of laparoscopic ovarian drilling in patients with anovulatory polycystic ovary syndrome and high serum levels of anti-Müllerian hormone.

Female infertility is often associated with anovulatory polycystic ovary syndrome (PCOS), characterized by high serum levels of anti-Müllerian hormone (AMH). Laparoscopic ovarian drilling (LOD) is commonly used to treat PCOS, especially when drug interventions have failed. This study aimed to evaluate the response to LOD intervention in women with PCOS by assessing AMH serum levels and their ability to restore normal physiological menstrual cycle and achieve conception. Seventy-five infertile women (24-41 years old) with body mass index (BMI) ranging from 19.6-35kg/m2 were included in the study. Among them, 57 had primary infertility, and 18 from secondary infertility, with an average duration of 8.6±4.4 years. Baseline levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and AMH were measured, and post-LOD levels of LH and AMH were evaluated. Menstrual cycle regularity was evaluated before and after LOD. Baseline FSH serum level before LOD was 5.2-1.6IU/L. Following LOD, the serum levels of LH and AMH significantly decreased from 14.3±4.1 to 7.8±2.8 IU/L and from 13.7±5.9 to 7.7±3.9 IU/L, respectively (p<0.05). LOD significantly (p<0.05) decreased the menstrual cycles irregularity, such as oligomenorrhea and amenorrhea, from 55 (73.3%) to 22 (29.3%) women and from 2 (2.7%) to 0 (0%) women respectively. Moreover, regular menstrual cycles significantly (p<0.05) increased from 18 (24%) to 53 (70.7%) women. Importantly, 68% of LOD-treated women showed a significant increase in pregnancy rates, with 52.9%, 35.3%, and 11.8% achieving pregnancy within 3, 6, and 9 months after LOD, respectively (p<0.05). Moreover, spontaneous ovulation was observed in 7/75 (9.3%) women within 90 days after LOD, and 71.4% achieved pregnancy. These findings highlight the success of laparoscopic ovarian drilling as an intervention for PCOS, with AMH serving as a reliable test to assess the response to LOD treatment.

[Impact of Endometriosis on the Therapeutic Effect of Hysteroscopic Fallopian Tube Catheterization Combined With Laparoscopy in Infertile Patients With Proximal Tubal Obstruction].

Objective: To investigate the impact of endometriosis on the therapeutic effect of hysteroscopic fallopian tube catheterization combined with laparoscopy in infertile patients with proximal tubal obstruction. Methods: We conducted a retrospective analysis of patients who underwent hysteroscopic fallopian tube catheterization combined with laparoscopy for infertility caused by proximal fallopian tube obstruction between January 19, 2016 and March 20, 2020 at the Department of Reproductive Endocrinology, West China Second Hospital, Sichuan University. During the operation, hydrotubation was performed to verify whether there was proximal tubal obstruction. Then, the patients were categorized into an endometriosis group and a non-endometriosis group according to whether their proximal tubal obstruction was combined with endometriosis. The baseline data were balanced by propensity score matching and the rate of successful surgical unblocking of proximal tubal obstruction in infertile patients by hysteroscopic fallopian tube catheterization combined with laparoscopy was calculated. Treating cases lost to follow-up in both groups as non-pregnant cases according to the principle of intention-to-treat analysis, we followed up the pregnancy outcomes after surgery. The primary indicators included overall successful surgical unblocking rate, clinical pregnancy rate, and spontaneous pregnancy rate, while the secondary indicators included live birth rate, miscarriage rate, ectopic pregnancy rate, and the mean time to spontaneous pregnancy after surgery. The primary indicators included overall successful surgical unblocking rate, clinical pregnancy rate, and spontaneous conception rate, while the secondary indicators included live birth rate, miscarriage rate, ectopic pregnancy rate, and the mean time to spontaneous pregnancy after surgery. Results: After propensity score matching, 113 cases were included in each of the two groups, with the overall successful surgical unblocking rate being 72.6%. The successful surgical unblocking rate of patients in the endometriosis group was higher than that of the non-endometriosis group, with the difference being statistically significant (78.8% vs. 66.4%, P<0.05). A total of 38 patients were lost after follow-up matching. Postoperative follow-up was performed to date and, through intention-to-treat analysis, the spontaneous conception rate was found to be higher in the endometriosis group than that in the non-endometriosis group (44.2% vs. 30.1%, P<0.05), while the mean time to spontaneous pregnancy after surgery was shorter in the endometriosis group than that in the non-endometriosis group (46 months vs. 53 months, P<0.05). There was no significant difference in clinical pregnancy rate, live birth rate, miscarriage rate, and ectopic pregnancy rate between the endometriosis group and the non-endometriosis group ( P>0.05). Conclusion: When infertility caused by proximal tubal obstruction is combined with endometriosis, performing hysteroscopic fallopian tube catheterization combined with laparoscopy contributes to the improvement of reproduction outcomes.

Efficacy of Hysteroscopy in Improving Fertility Outcomes in Women Undergoing Assisted Reproductive Technique: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

INTRODUCTION: Usefulness of hysteroscopy before assisted reproductive technique (ART) was considered debatable. However, over the last decade, several new trials have been added to available literature. We aimed to assess the impact of diagnostic and operative hysteroscopy on reproductive outcomes of infertile women with and without intrauterine abnormalities. MATERIALS AND METHODS: MEDLINE, Scopus, SciELO, Embase, Cochrane Library at CENTRAL, PROSPERO, CINAHL, grey literature, conference proceedings, and international controlled trials registries were searched without temporal, geographical, or language restrictions. Randomized controlled trials (RCTs) of infertile women comparing hysteroscopy versus no hysteroscopy prior to the first ART or after at least one failed attempt were included. RCTs of infertile women with intrauterine pathology comparing diagnostic versus operative hysteroscopy were included in separate analysis. Random-effect meta-analysis was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Grading of Recommendations, Assessment, Development and Evaluation and Cochrane criteria were used for quality of evidence and risk of bias assessment. Primary outcome was live birth rate (LBR). Secondary outcomes were clinical pregnancy (CPR) and pregnancy loss rate. RESULTS: Fifteen studies (5,038 women) were included. Compared to no hysteroscopy before first or after failed ART attempts, moderate-quality evidence showed that hysteroscopy increased the LBR (relative risk [RR] 1.24, 95% confidence interval [CI] 1.09-1.43, I2 = 21%), confirmed by subgroup analysis for women with failure after one or more ART cycles (RR 1.43, 95% CI: 1.19-1.72, I2 = 0%) but not before the first ART. Moderate-quality evidence showed that it increased the CPR (RR 1.36, 95% CI: 1.18-1.57; I2 = 51%), confirmed in subgroup analysis for both implantation failure (RR 1.40, 95% CI: 1.12-1.74, I2 = 52%) and before first ART (RR 1.32, 95% CI: 1.11-1.57, I2 = 42%). Low-quality data suggest that operative hysteroscopy increases CPR when used to treat intrauterine pathologies (RR 2.13, 95% CI: 1.56-2.92, I2 = 0%). CONCLUSIONS: Although moderate-quality evidence supports performing hysteroscopy before ART in women with history of implantation failure, hysteroscopic evaluation of uterine cavity should be considered a first-line technique in all infertile women undergoing ART. Additional high-quality RCTs are still needed, particularly to assess yield during couple's initial evaluation even before ART is considered.

Endometrial polyps effect on pregnancy outcomes in infertile women with minimal/mild endometriosis: A retrospective study.

OBJECTIVE: To assess the pregnancy outcomes and associated influencing factors of pregnancy after hysteroscopy combined with laparoscopy treatment in infertile patients with minimal/mild endometriosis. DESIGN: A retrospective study. SETTING: West China Second University Hospital of Sichuan University. PATIENTS: We enrolled 898 infertile women who had their minimal/mild endometriosis lesions removed by laparoscopy, including 271 patients additionally diagnosed with endometrial polyps who also underwent hysteroscopic polypectomy. METHODS: Based on the existence of endometrial polyps, patients with minimal/mild endometriosis were enrolled and divided into polyps group and non-polyps group. MAIN OUTCOME MEASURES: Pregnancy outcomes. RESULTS: A total of 271 women with minimal/mild endometriosis were included in polyps group while 491 women with minimal/mild endometriosis were included in non-polyps group. The pregnancy rate of polyps group was not statistically significant compared with non-polyp group (60.15% vs. 58.25%). The pregnancy rate was higher among patients with polyps ≥1 cm (76.06%, 54/71) than patients with polyps <1 cm (54.50%, 109/200) or patients without polyps (58.25%, 286/491) (p = 0.006). The pregnancy rate was higher for patients with multiple polyps (67.86%, 95/140) than for patients with single polyp (51.91%, 68/131) or without polyps (p = 0.025). CONCLUSIONS: Among women with minimal/mild endometriosis, hysteroscopic polypectomy did significantly increase fertility in infertile patients with multiple polyps or size of polyp ≥1 cm compared with those without endometrial polyps, single polyp, and size of polyp <1 cm. The size and number of polyps were independently associated with the reproductive ability of women with minimal/mild endometriosis.

Comparisons of different treatment outcomes in IVF/ET patients with hydrosalpinx: a retrospective study.

AIMS: To explore suggestions for clinicians on the most effective treatment for hydrosalpinx undergoing IVF-ET. MATERIALS AND METHODS: We reviewed 936 women with hydrosalpinx and 6715 tubal infertile women without hydrosalpinx who underwent IVF/ICSI between January 2014 and August 2019 in our center. Hydrosalpinx patients received different treatments including laparoscopic surgery (only salpingectomy and proximal tubal occlusion/ligation were included), ultrasonic-guided aspiration and hysteroscopic tubal occlusion. Outcomes were analyzed by One-way ANOVA, Chi-Square test and logistic regression. RESULTS: The live birth rate (LBR) of laparoscopic surgery was significantly higher compared with hydrosalpinx aspiration (48.3% vs 39.6%, p = .024). The cumulative live birth rate (CLBR) of subsequent laparoscopic surgery was significantly higher compared with subsequent hysteroscopic occlusion (65.1% vs 34.1%, p = .001) and no subsequent treatment (65.1% vs 44.9%, p < .005). Subsequent laparoscopic surgery significantly improved the CLBR of hydrosalpinx patients who received ultrasonic-guided aspiration and didn't get clinical pregnancy in fresh cycles (Odds Ratio (OR) =1.875; 95%CI = 1.041-3.378, p = .036). CONCLUSIONS: Laparoscopic surgery leads to significantly higher LBR than ultrasonic-guided aspiration and significantly higher CLBR than hysteroscopic occlusion and no treatment.

Deceased donor availability for uterus transplantation in Australia.

BACKGROUND: Uterus transplantation is an emerging treatment option for uterine factor infertility. Most uterus transplantation research programs use living donors, although this comes with considerable surgical and psychological risks and not all women desiring uterus transplantation will have an available living donor. A deceased donor program eliminates donor risks; however, the availability of deceased uterus donors is currently unknown in Australia. AIMS: To establish the feasibility of a deceased donor uterus transplantation program in Australia and consider expanded inclusion criteria for this model. MATERIALS AND METHODS: A retrospective review of the New South Wales (NSW) Organ and Tissue Donation Service database was undertaken to identify potential deceased uterus donors, with comparison to the broad deceased donor inclusion criteria from three international uterus transplantation trials including female, brain-dead, multi-organ donation, no major abdominal surgery, and <60 years of age. RESULTS: Between January 1, 2018, and December 31, 2022, 648 deceased donors were available in NSW. Of these, 43% (279/648) were female and 67% of the women (187/279) were also multi-organ donors. When the brain-dead donor-only and age criteria (<60 years) were applied, a total of 107 deceased donors met the available criteria for uterus transplantation, with an average of 21 deceased donors per year in NSW. CONCLUSIONS: There appears to be adequate deceased donor organ availability to establish a deceased uterus transplantation program in NSW, Australia. Should interest in uterus transplantation increase, including criteria such as older and nulliparous donors could increase organ availability for a uterus transplantation program.

Effectiveness of laparoscopic niche resection versus expectant management in patients with unexplained infertility and a large uterine caesarean scar defect (uterine niche): protocol for a randomised controlled trial (the LAPRES study).

INTRODUCTION: A uterine niche is a defect at the site of the uterine caesarean scar that is associated with gynaecological symptoms and infertility. Promising results are reported in cohort studies after a laparoscopic niche resection concerning reduction of gynaecological symptoms in relation to baseline and concerning pregnancy outcomes. However, randomised controlled trials to study the effect of a laparoscopic niche resection on reproductive outcomes in infertile women are lacking. This study will answer the question if laparoscopic niche resection in comparison to expectant management improves reproductive outcomes in infertile women with a large uterine niche. METHODS AND ANALYSIS: The LAPRES study is a randomised, non-blinded, controlled trial, including 200 infertile women with a total follow-up of 2 years. Women with the presence of a large niche in the uterine caesarean scar and unexplained infertility of at least 1 year or failed IVF will be randomly allocated to a laparoscopic niche resection within 6 weeks or to expectant management for at least 9 months. A large niche is defined as a niche with a depth of >50% of the myometrial thickness and a residual myometrium of ≤3 mm on transvaginal ultrasound. Those receiving expectant management will be allowed to receive fertility therapies, including assisted reproductive techniques, if indicated. The primary outcome is time to ongoing pregnancy, defined as a viable intrauterine pregnancy at 12 weeks' gestation. Secondary outcome measures are time to conception leading to a live birth, other pregnancy outcomes, received fertility therapies after randomisation, menstruation characteristics, patient satisfaction, quality of life, additional interventions, and surgical and ultrasound outcomes (intervention group). Questionnaires will be filled out at baseline, 6, 12 and 24 months after randomisation. Ultrasound evaluation will be performed at baseline and at 3 months after surgery. ETHICS AND DISSEMINATION: The study protocol was approved by the medical ethics committee of the Amsterdam University Medical Centre. (Ref. No. 2017.030). Participants will sign a written informed consent before participation. The results of this study will be submitted to a peer-reviewed journal for publication.
