Does ovarian cystectomy pose a risk to ovarian reserve and fertility?

Key content The impact of benign ovarian cysts on a woman’s fertility is dependent on the nature, size, number, bilaterality and risk of recurrence of the cyst(s). Children and adolescents presenting with pathological ovarian cysts require a multidisciplinary team approach and, where possible, fertility sparing treatment should be offered. Laparoscopic detorsion has the potential to preserve ovarian reserve and should remain the optimal treatment for ovarian torsion in girls and premenopausal women. Surgery for bilateral endometriomas has been shown to increase the risk of developing premature ovarian insufficiency. It is important to consider performing ovarian reserve assessments before any ovarian surgery in women who have not completed their family. Learning objectives To understand what factors need to be considered before making a decision to perform an ovarian cystectomy. To be aware of different surgical techniques and their impact on fertility outcomes. To take anatomical considerations into account to minimise damage to healthy ovarian tissue. Ethical issues The UK’s National Health Service does not routinely fund oocyte freezing for benign conditions

Risk prediction of major haemorrhage with surgical treatment of live cesarean scar pregnancies

Objective: To evaluate the association between demographic and ultrasound variables and major intra-operative blood loss during surgical transcervical evacuation of live caesarean scar pregnancies. Study Design: This was a retrospective cohort study conducted in a tertiary referral center between 2008 and 2019. We included all women diagnosed with a live caesarean scar ectopic pregnancy who chose to have surgical management in the study center. A preoperative ultrasound was performed in each patient. All women underwent transcervical suction curettage under ultrasound guidance. Our primary outcome was the rate of postoperative blood transfusion. The secondary outcomes were estimated intra-operative blood loss (ml), rate of retained products of conception, need for repeat surgery, need for uterine artery embolization and hysterectomy rate. Descriptive statistics were used to describe the variables. Univariate and multivariable logistic regression models were constructed using the relevant covariates to identify the significant predictors for severe blood loss. Results: During the study period, 80 women were diagnosed with a live caesarean scar pregnancy, of whom 62 (78%) opted for surgical management at our center. The median crown-rump length was 9.3 mm (range 1.4–85.7). Median blood loss at the time of surgery was 100 ml (range, 10–2300), and six women (10%; 95%CI 3.6–20) required blood transfusion. Crown-rump length and presence of placental lacunae were significant predictive factors for the need for blood transfusion and blood loss > 500 ml at univariate analysis (p < .01); on multivariate analysis, only crown-rump length was a significant predictor for need for blood transfusion (OR = 1.072; 95% CI 1.02–1.11). Blood transfusion was required in 6/18 (33%) cases with the crown-rump length ≥ 23 mm (≥9+0 weeks of gestation), but in none of 44 women presenting with a crown-rump length < 23 mm (p < .01). Conclusion: The risk of severe intraoperative bleeding and need for blood transfusion during or after surgical evacuation of live caesarean scar pregnancies increases with gestational age and is higher in the presence of placental lacunae. One third of women presenting at ≥ 9 weeks of gestation required blood transfusion and their treatment should be ideally arranged in specialized tertiary centers

Impact of location on placentation in live tubal and cesarean scar ectopic pregnancies

INTRODUCTION: The objective of this study was to evaluate the impact of implantation outside the normal intra-uterine endometrium on development of the gestational sac. METHODS: We reviewed and compared the ultrasound measurements and vascularity score around the gestational sac in 69 women diagnosed with a live tubal ectopic pregnancy (TEP) and 54 with a cesarean scar ectopic pregnancy (CSP) at 6-11 weeks of gestation who were certain of their last menstrual period. RESULTS: The rate of a fetus with a cardiac activity in the study population was significantly (P < 0.001) higher in CSPs than in TEPs. The median maternal age, gravidity and parity were significantly (P =.005; P < 0.001 and P < 0.001, respectively) lower in the TEP than in the CSP group. The number of gestational sac size <5th centile for gestational age was significantly (P < 0.001) higher in the TEP than in the CSP group. There were no differences between the groups for the other ultrasound measurements. In cases matched for gestational age, the gestational sac size was significantly (P < 0.001) smaller in the TEP compared to the CSP group. There was a significant (P < 0.001) difference in the distribution of blood flow score with CSP presenting with higher incidence of moderate and high vascularity than TEP. DISCUSSION: Both TEP and CSP are associated with a higher rate of miscarriage than intrauterine pregnancies and the slow development of the gestation sac is more pronounced in TEPs probably as a consequence of a limited access to decidual gland secretions

Variation in antral follicle counts at different times in the menstrual cycle: does it matter?

Antral follicle count (AFC) variation was examined across the menstural cycle and its effect on clinical management assessed. In 79 women, AFC was documented in early (iAFC) and late follicular phase (sAFC). Absolute agreement between iAFC and sAFC and agreement for classification into categories of risk of extremes of ovarian response were examined. Ovarian stimulation protocols designed with iAFC and sAFC, and the predictive value of iAFC and sAFC for extremes of ovarian response, were compared in women undergoing ovarian stimulation. Significant differences were found between iAFC and sAFC (16 [IQR 9-24] versus 13 [IQR 7- 21]; P = 0.001), with moderate agreement for the classification into at risk of extremes of response (k = 0.525). Agreement for protocol selection based on either AFC (k = 0.750) and starting gonadotrophin dose was good (concordance correlation coefficient 0.970 [95% CI 0.951 to 0.982]). Predictive value for iAFC and sAFC was maintained for poor ovarian response and risk of ovarian hyperstimulation syndrome (OR 0.634 [0.427 to 0.920], 0.467 [0.233 to 0.935]) and (OR 1.049 [0.974 to 1.131], 1.140 [1.011 to 1.285]). Across the cycle, AFC varies but does not significantly affect ovarian stimulation protocol design and prediction of extreme ovarian response

Impact of the SARS-CoV-2 pandemic on access to contraception and pregnancy intentions: a national prospective cohort study of the UK population

OBJECTIVE: Evaluate the impact of the COVID-19 pandemic on access to contraception and pregnancy intentions. DESIGN: Nationwide prospective cohort study. SETTING: United Kingdom. PARTICIPANTS: Women in the UK who were pregnant between 24 May and 31 December 2020. MAIN OUTCOME MEASURES: Access to contraception and level of pregnancy intentions, using the London Measure of Unplanned Pregnancy (LMUP) in women whose last menstrual period was before or after 1 April 2020. While the official date of the first UK lockdown was 23 March, we used 1 April to ensure that those in the post-lockdown group would have faced restrictions in the month that they conceived. RESULTS: A total of 9784 women enrolled in the cohort: 4114 (42.0%) conceived pre-lockdown and 5670 (58.0%) conceived post-lockdown. The proportion of women reporting difficulties accessing contraception was higher in those who conceived after lockdown (n=366, 6.5% vs n=25, 0.6%, p<0.001) and continued to rise from March to September 2020. After adjusting for confounders, women were nine times more likely to report difficulty accessing contraception after lockdown (adjusted odds ratio (aOR) 8.96, 95% CI 5.89 to 13.63, p<0.001). There is a significant difference in the levels of pregnancy planning, with higher proportions of unplanned (n=119, 2.1% vs n=55, 1.3%) and ambivalent pregnancies (n=1163, 20.5% vs n=663, 16.1%) and lower proportions of planned pregnancies (n=4388, 77.4% vs n=3396, 82.5%) in the post-lockdown group (p<0.001). After adjusting for confounders, women who conceived after lockdown were still significantly less likely to have a planned pregnancy (aOR 0.88, 95% CI 0.79 to 0.98, p=0.025). CONCLUSIONS: Access to contraception in the UK has become harder during the COVID-19 pandemic and the proportion of unplanned pregnancies has almost doubled

Natural history of ovarian endometrioma in pregnancy.

Ovarian endometriomas are classified as benign ovarian lesions. During pregnancy endometriomas may undergo major morphological changes which are referred to as 'decidualisation'. Decidualised ovarian endometrioma may resemble malignant ovarian tumours on ultrasound examination. The aim was to study variations in the morphology and size of ovarian endometriomas diagnosed on ultrasound during pregnancy

Discovery of non-invasive biomarkers for the diagnosis of endometriosis

Background Endometriosis is a common gynaecological disorder affecting 5–10% of women of reproductive age who often experience chronic pelvic pain and infertility. Definitive diagnosis is through laparoscopy, exposing patients to potentially serious complications, and is often delayed. Non-invasive biomarkers are urgently required to accelerate diagnosis and for triaging potential patients for surgery. Methods This retrospective case control biomarker discovery and validation study used quantitative 2D-difference gel electrophoresis and tandem mass tagging–liquid chromatography–tandem mass spectrometry for protein expression profiling of eutopic and ectopic endometrial tissue samples collected from 28 cases of endometriosis and 18 control patients undergoing surgery for investigation of chronic pelvic pain without endometriosis or prophylactic surgery. Samples were further sub-grouped by menstrual cycle phase. Selected differentially expressed candidate markers (LUM, CPM, TNC, TPM2 and PAEP) were verified by ELISA in a set of 87 serum samples collected from the same and additional women. Previously reported biomarkers (CA125, sICAM1, FST, VEGF, MCP1, MIF and IL1R2) were also validated and diagnostic performance of markers and combinations established. Results Cycle phase and endometriosis-associated proteomic changes were identified in eutopic tissue from over 1400 identified gene products, yielding potential biomarker candidates. Bioinformatics analysis revealed enrichment of adhesion/extracellular matrix proteins and progesterone signalling. The best single marker for discriminating endometriosis from controls remained CA125 (AUC = 0.63), with the best cross-validated multimarker models improving the AUC to 0.71–0.81, depending upon menstrual cycle phase and control group. Conclusions We have identified menstrual cycle- and endometriosis-associated protein changes linked to various cellular processes that are potential biomarkers and that provide insight into the biology of endometriosis. Our data indicate that the markers tested, whilst not useful alone, have improved diagnostic accuracy when used in combination and demonstrate menstrual cycle specificity. Tissue heterogeneity and blood contamination is likely to have hindered biomarker discovery, whilst a small sample size precludes accurate determination of performance by cycle phase. Independent validation of these biomarker panels in a larger cohort is however warranted, and if successful, they may have clinical utility in triaging patients for surgery

ESHRE/ESGE female genital tract anomalies classification system—the potential impact of discarding arcuate uterus on clinical practice

STUDY QUESTION What would be a potential impact of implementing the new ESHRE/European Society of Gynaecological Endoscopy (ESGE) female genital anomalies classification system on the management of women with previous diagnosis of arcuate uteri based on the modified American Society for Reproductive Medicine (ASRM) criteria? SUMMARY ANSWER A significant number of women with previous diagnosis of arcuate uteri are reclassified as having partial septate uteri according to the new ESHRE/ESGE classification system which may increase the number of remedial surgical procedures. WHAT IS KNOWN ALREADY The ESHRE/ESGE classification system has defined measurement techniques, reference points and specific cut-offs to facilitate the differentiation between normal and septate uteri. These criteria have been arbitrarily defined and they rely on the measurement of uterine wall thickness and depth of distortion of uterine fundus. STUDY DESIGN, SIZE, DURATION This was a retrospective cohort study. We searched our ultrasound clinic database from January 2011 to December 2014 to identify all women diagnosed with arcuate uterus on three-dimensional ultrasound according to the modified ASRM criteria. PARTICIPANTS/MATERIALS, SETTING, METHODS For each woman, the ultrasound images were stored in our clinical database and they were re-examined according to ESHRE/ESGE specifications. The presence and location of all acquired uterine anomalies, such as fibroids or adenomyosis was noted. We applied the two diagnostic approaches as specified by the ESHRE/ESGE classification: the main option (MO) and the alternative option (AO). We used the Kappa statistic to quantify the agreement between the two approaches. We also compared the number of previous miscarriages in women with normal and partial septate uteri according to the ESHRE/ESGE classification. Non-parametric Mann–Whitney and Kruskal–Wallis tests were used for the analyses and receiver-operating characteristic curves were constructed to assess the predictive values of the calculated uterine distortion indices for the detection of women at risk of suffering multiple pregnancy losses. MAIN RESULTS AND THE ROLE OF CHANCE We included 270 women diagnosed with arcuate uterus in the study. In all, 77 women (28.5%, 95% confidence interval (CI) 23.1–33.9) had evidence of fibroids or adenomyosis. These abnormalities precluded the application of either proposed ESHRE/ESGE techniques to assess uterine morphology in 25 women (9.3%, 95% CI 5.8–12.7). When using the MO, 138/237 (58.2%, 95% CI 51.9–64.3) women were diagnosed with partial septate uterus compared to 61/230 (26.5%, 95% CI 21.2–32.6) women when using the AO. In 222 women in whom we were able to apply both MO and AO, there was agreement in the diagnosis of septate uterus between the two techniques in 146/222 cases (65.8%, 95% CI 59.3–71.7; Kappa 0.42, 95%CI 0.35–0.5). There was no statistical difference in the proportion of women with history of previous multiple miscarriages between those diagnosed with normal or partial septate uteri using either MO (6.2%, 95% CI 2.9–12.9 vs. 9.5%, 95% CI 5.6–15.6; P = 0.47) or AO (7.2%, 95% CI 4.2–12.1 vs. 11.7%, 95% CI 5.8–22.2; P = 0.29). LIMITATIONS, REASONS FOR CAUTION This study was retrospective in nature and the definition of arcuate uterus used in the study is not universally accepted. The reproductive history data were collected retrospectively and therefore may be prone to bias. WIDER IMPLICATIONS OF THE FINDINGS There are methodological weaknesses in the new ESHRE/ESGE classification system which would need to be addressed in future revisions. There was no significant difference in the past reproductive outcomes between women diagnosed with normal and anomalous uteri and the clinicians should exercise caution when offering surgical correction to women diagnosed with partial septate uteri using the new ESHRE/ESGE classification.
