RESUMO

Pregnant women represent a high-risk population for Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection. The presence of SARS-CoV-2 has been reported in placenta from infected pregnant women, but whether the virus influences placenta immune response remains unclear. We investigated the properties of maternal-fetal interface macrophages (MFMs) in a cohort of unvaccinated women who contracted coronavirus disease 2019 (COVID-19) during their pregnancy. We reported an infiltration of CD163+ macrophages in placenta from COVID-19 women 19 whereas lymphoid compartment was not affected. Isolated MFMs exhibited nonpolarized activated signature (NOS2, IDO1, IFNG, TNF, TGFB) mainly in women infected during the second trimester of pregnancy. COVID-19 during pregnancy primed MFM to produce type I and III interferon response to SARS-CoV-2 (Wuhan and δ strains), that were unable to elicit this in MFMs from healthy pregnant women. COVID-19 also primed SARS-CoV-2 internalization by MFM in an angiotensin-converting enzyme 2-dependent manner. Activation and recall responses of MFMs were influenced by fetal sex. Collectively, these findings support a role for MFMs in the local immune response to SARS-CoV-2 infection, provide a basis for protective placental immunity in COVID-19, and highlight the interest of vaccination in pregnant women.

RESUMO

RESEARCH QUESTION: Does positive Chlamydia trachomatis serology have an impact on the cumulative live birth rate from IVF? DESIGN: A retrospective matched cohort study compared women with positive Chlamydia trachomatis serology (group A) who underwent IVF treatment between January 2016 and December 2021 with a control group of women with negative Chlamydia trachomatis serology (group B). The main outcome measures were the cumulative live birth rate per IVF cycle and the live birth rate per embryo transfer. Secondary outcomes were the cumulative rates of clinical pregnancy, ectopic pregnancy and pregnancy loss calculated per IVF cycle and per embryo transfer. RESULTS: A total of 151 women in group A were matched 1:2 to 302 women in group B, representing 220 and 440 IVF cycles, respectively. Women with a history of Chlamydia trachomatis infection had a significantly higher rate of tubal obstruction (P < 0.001), excluded or operated hydrosalpinx (P = 0.002) and/or history of chronic endometritis (P < 0.001). There were no statistically significant differences between the two groups in the mean number of mature oocytes retrieved, fertilization rate or implantation rate. The IVF cumulative live birth rate per cycle was similar in the two groups (36.7% in group A versus 34.9% in group B, P = 0.692). The cumulative rates of clinical pregnancy, pregnancy loss, biochemical pregnancy and ectopic pregnancy were comparable between the two groups. CONCLUSION: Positive Chlamydia trachomatis serology has no impact on IVF pregnancy outcomes.

RESUMO

STUDY OBJECTIVE: To describe a minimal invasive 10-step technique of laparoscopic multibipolar radiofrequency myolysis for symptomatic myomas. DESIGN: A step-by-step video demonstration of the technique. SETTING: A woman with symptomatic FIGO 5 myoma of 60 mm of diameter, confirmed by magnetic resonance imaging. The patient included in this video gave consent for publication of the video and posting of the video online including social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus, etc.) and other applicable sites. INTERVENTIONS: Approximately 30% of women of child-bearing age with myomas will present with symptoms [1] that include chronic pelvic pain, abnormal uterine bleeding or infertility [2,3]. Data regarding fertility preservation and obstetric outcomes suggest that radiofrequency myoma ablation may offer an alternative to existing treatments for women who desire future fertility [4]. The local institutional review board stated that approval was not required because the video describes a technique and not a clinical case. In our center, all radiofrequency indications are discussed during a monthly multidisciplinary myomas meeting. This video presents the procedure divided into the following 10 steps: planning of the surgery; materials; installation; laparoscopic exploration; transvaginal ultrasound examination; visual and transvaginal ultrasound guided transparietal puncture of the myoma; control of the applicators' position; radiofrequency myolysis; end of myolysis, applicators removal; final check and additional procedures. CONCLUSION: Radiofrequency myolysis is a simple and reproductible procedure that can be offered as an alternative to myomectomy [5]. This video presents 10 steps to make the procedure easier to adopt and to reduce its learning curve.

RESUMO

PURPOSE: Only a few case reports have described heterotopic ovarian tissue transplantation (OTT) with the only objective of restoring ovarian function. METHODS: Case report and review of the literature for reporting cases of heterotopic OTT with the only aim of restoring ovarian endocrine function. In a cancer survivor woman with a history of hysterectomy and bilateral oophorectomy for cervical cancer and because she poorly tolerated hormone replacement therapy (HRT), we performed a heterotopic OTT in a pelvic subcutaneous "pocket" after an OT cryostorage of 17 years. RESULTS: A cyclic ovarian endocrine function started 3 months after OTT with an immediate patient self-described improvement of her quality of life. A second OTT was performed 19 months after, due to hot flushes recurrence and FSH increase. Despite a cyclic endocrine function, progesterone levels have always been low, resulting in a relative hyperoestrogenism state. CONCLUSION: In the future, the indications of heterotopic OTT could be spread in alternative to HRT. However, our data suggest that the heterotopic graft environment is less favorable to corpus luteum development, and further studies are needed to assay the best site of heterotopic graft, the optimal number of ovarian cortex fragments to graft, and the potential risk of relapse in case of malignant residual disease.

RESUMO

RESEARCH QUESTION: Does moderate-to-severe endometriosis have an impact on cumulative live birth rates (cLBR) and IVF outcomes? DESIGN: In this retrospective matched cohort study, women with moderate-to-severe endometriosis undergoing IVF or intracytoplasmic sperm injection treatment from January 2015 to December 2020 were matched 1:2 to women with other causes of infertility (control group). The main outcome was cLBR per cycle and per woman, and secondary outcomes were number of oocytes retrieved and number of mature oocytes, fertilization rate, total number of embryos and usable embryos, implantation rate, clinical pregnancy rate and miscarriage rate per cycle. RESULTS: In total, 195 women with endometriosis were matched with 390 women without endometriosis (323 and 646 cycles, respectively). Women with endometriosis had significantly fewer oocytes retrieved than women in the control group (P=0.003) despite higher doses of gonadotropins, but had a similar number of mature oocytes, fertilization rate, and total number of embryos and usable embryos. cLBR per cycle and per women did not differ significantly between the endometriosis group and the control group (19.8% versus 24.3%, P = 0.12; 32.3% versus 37.2%, P = 0.24, respectively). In women with endometrioma, a history of cystectomy did not impact cLBR per cycle (28.3% versus 31.9%, P = 0.68). We did not observe any significant impact of tobacco use in the endometriosis group compared with the control group (16.4% versus 25.9%, P = 0.13). CONCLUSION: This matched cohort study did not observe a significant impact of moderate-to-severe endometriosis on cLBR among women undergoing IVF. These data are reassuring for the counselling of infertile women with endometriosis before IVF.

RESUMO

The objective of this study was to explore and describe the specificities of the occupational life of infertile endometriotic women treated by in vitro fertilization. We conducted a qualitative monocentric study between December 2020 and June 2021. Twelve semi-structured in-depth interviews using a theme-based interview guide with open questions were undertaken with infertile women with deep infiltrating endometriosis. Data analysis was conducted using an inductive approach according to the grounded theory method. Three main themes emerged from the interviews: (i) barriers to reconciling illness and work life, (ii) facilitating factors for well-being at work, and (iii) consequences and outlooks. It appeared that the time of infertility treatment represents a particular period of change in the working lives of women with endometriosis. For most women, these changes are experienced negatively, often with a renunciation of goals. For others, this is the time to communicate the difficulties linked to their illness to their professional entourage. There is a long path ahead to finally achieving recognition of endometriosis in the context of professional life.

RESUMO

STUDY OBJECTIVE: To evaluate the feasibility, efficacy, and morbidity of Essure® device removal via laparoscopic en bloc salpingectomy-cornuectomy resection (LSC) and the utility of confirmation of complete removal with an intraoperative X-ray of the removed specimen (IX-S). DESIGN: Retrospective observational cohort study. SETTING: Academic hospitals of La Conception, Marseille, and Arnaud-de-Villeneuve, Montpellier, France. PATIENTS: Women who were not seeking future fertility seeking Essure® device removal by salpingectomy, between February 2017 and August 2018. INTERVENTIONS: All women underwent LSC. An IX-S was performed to confirm complete Essure® device removal. In the case of an unsatisfactory IX-S, an intraoperative pelvic X-ray control of the patient (IX-P) was performed. If IX-P diagnosed residual Essure® fragments, an additional resection was performed, and the removed tissue was checked by IX-S. MEASUREMENTS AND MAIN RESULTS: We included 72 women, and a total of 140 Essure® devices were removed. The IX-S confirmed complete Essure® device removal in 131 of 140 cases (93.6%) in 63 of 72 women (87.5%). Out of the 9 women with unsatisfactory IX-S, 6 had no residual Essure® fragments at IX-P, and Essure® device removal was considered complete. Three women had a persistent Essure® fragment at IX-P: an additional resection allowed complete removal in 2 cases and resulted in failure in 1 of 140 case (0.7%). There were 2 of 72 women (2.8%) intraoperative complications and 4 of 72 women (5.6%) postoperative grade 1 complications according to the Clavien-Dindo classification. CONCLUSION: Essure® device removal by LSC appears to be an effective and safe procedure. IX-S is a useful method to evaluate whether the removal of Essure® device is complete during an LSC procedure.

RESUMO

OBJECTIVE: To study the effectiveness of a new intrauterine degradable polymer film (Womed Leaf®) in the management of moderate to severe IUA. DESIGN: PREG2 study was a multi-centre, double-blind, randomised, controlled, stratified, two-arm superiority clinical trial conducted in 16 centres in 7 countries. SUBJECTS: Patients ≥18 years scheduled for hysteroscopic adhesiolysis because of symptomatic severe or moderate adhesions (according to American fertility society (AFS) IUA score) were considered eligible for the study. INTERVENTION: Following adhesiolysis, patients were randomised at a 1:1 ratio to either have a Womed Leaf film inserted (intervention group) or not (control group). MAIN OUTCOME MEASURES: The primary effectiveness endpoint of the study was the change in AFS IUA score on second-look hysteroscopy (SLH), assessed by an independent evaluator, compared to baseline. Information on rate of no IUA and responder rate were collected as secondary effectiveness outcomes, and reported adverse events and patient reported outcomes as safety and tolerability measures. RESULTS: Between October 26, 2021, and September 28, 2023, a total of 160 women were randomised (Womed Leaf: n=75 and controls: n=85). The reduction in IUA AFS score on SLH was significantly higher in the intervention compared to the control group (mean 5.2 ± 2.8 vs. 4.2 ± 3.2; p=0.0153). Similarly, the absence of adhesions on SLH was significantly higher in the intervention group (41% vs 24% OR 2.44 [CI 1.161 - 5.116]; p=0.0189). None of the reported adverse events were serious or considered related to the device. CONCLUSION: Womed Leaf is effective and safe in the management of symptomatic severe or moderate intrauterine adhesions.

RESUMO

OBJECTIVE: To update the 2010 CNGOF clinical practice guidelines for the first-line management of infertile couples. MATERIALS AND METHODS: Five major themes (first-line assessment of the infertile woman, first-line assessment of the infertile man, prevention of exposure to environmental factors, initial management using ovulation induction regimens, first-line reproductive surgery) were identified, enabling 28 questions to be formulated using the Patients, Intervention, Comparison, Outcome (PICO) format. Each question was addressed by a working group that had carried out a systematic review of the literature since 2010, and followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) methodology to assess the quality of the scientific data on which the recommendations were based. These recommendations were then validated during a national review by 40 national experts. RESULTS: The fertility work-up is recommended to be prescribed according to the woman's age: after one year of infertility before the age of 35 and after 6months after the age of 35. A couple's initial infertility work-up includes a single 3D ultrasound scan with antral follicle count, assessment of tubal permeability by hysterography or HyFOSy, anti-Mullerian hormone assay prior to assisted reproduction, and vaginal swabbing for vaginosis. If the 3D ultrasound is normal, hysterosonography and diagnostic hysteroscopy are not recommended as first-line procedures. Chlamydia trachomatis serology does not have the necessary performance to predict tubal patency. Post-coital testing is no longer recommended. In men, spermogram, spermocytogram and spermoculture are recommended as first-line tests. If the spermogram is normal, it is not recommended to check the spermogram. If the spermogram is abnormal, an examination by an andrologist, an ultrasound scan of the testicles and hormonal test are recommended. Based on the data in the literature, we are unable to recommend a BMI threshold for women that would contraindicate medical management of infertility. A well-balanced Mediterranean-style diet, physical activity and the cessation of smoking and cannabis are recommended for infertile couples. For fertility concern, it is recommended to limit alcohol consumption to less than 5 glasses a week. If the infertility work-up reveals no abnormalities, ovulation induction is not recommended for normo-ovulatory women. If intrauterine insemination is indicated based on an abnormal infertility work-up, gonadotropin stimulation and ovulation monitoring are recommended to avoid multiple pregnancies. If the infertility work-up reveals no abnormality, laparoscopy is probably recommended before the age of 30 to increase natural pregnancy rates. In the case of hydrosalpinx, surgical management is recommended prior to ART, with either salpingotomy or salpingectomy depending on the tubal score. It is recommended to operate on polyps>10mm, myomas 0, 1, 2 and synechiae prior to ART. The data in the literature do not allow us to systematically recommend asymptomatic uterine septa and isthmoceles as first-line surgery. CONCLUSION: Based on strong agreement between experts, we have been able to formulate updated recommendations in 28 areas concerning the initial management of infertile couples.

RESUMO

Plant SUMO conjugation is an essential posttranslational modification involved in plant development and responses to environmental stress. Most likely, this biological diversification is supported by a functional specialization of the different isoforms of the SUMO conjugation machinery. For instance, the two essential Arabidopsis SUMO isoforms, SUMO1/2, display higher conjugation rate than SUMO3 and 5, which are not essential, linking their specific biochemical properties to their biological role. To study the biochemical properties of plant SUMO conjugation systems, quantitative biochemical assays must be performed. We will present a detailed protocol for reconstituting an in vitro SUMO conjugation assay covering all steps from protein preparation to assay development.

RESUMO

Five to 20% of women regret having a tubal ligation. These women are generally otherwise fertile and have a better chance of pregnancy than other patients experiencing infertility, whether by in vitro fertilization or after tubal surgery. Historically, tubal anastomosis surgery has long been performed by microsurgery through laparotomy, which provided very high precision but was associated with some degree of morbidity. The parallel development of in vitro fertilization and laparoscopy have contributed to reducing the indications for tubal surgery. The laparoscopic approach is challenging because of the number and precision of the sutures needed. The robot-assisted laparoscopic approach may reduce the surgical difficulty and improve the accessibility of this technique. We have described the technique of tubo-tubal reanastomosis after sterilization with robot-assisted laparoscopy in 10 steps. Robot-assisted laparoscopy provides favourable conditions for performing tubo-tubal reanastomosis after sterilization due to the camera stability, precision of movement, and amplitude of articulations.

RESUMO

INTRODUCTION: Women frequently report pain associated with medical termination of pregnancy (MToP), and its management can differ largely between centres. This study aimed at evaluating in real-life settings pain related to MToP and its management in France. METHODS: This was a non-interventional prospective, longitudinal study run in 23 centres between 2015 and 2016 that included 893 pregnant women. Pain was reported by women prior any curative analgesic intake (CAI) through a five-level Likert scale (absence, mild, moderated, severe, extreme). Modalities of analgesic prophylaxis prescription (APP) and intake (API) and CAI were collected. Risk factors were investigated using ordinal logistic regression (for pain) or logistic regression (for CAI) with stepwise selection of variables. RESULTS: APP was prescribed to 657 (73.7%) women irrespective of the gestational age, among whom 386 (73.7%) took the treatment. Out of 740 women who documented their pain symptoms prior to any CAI, few declared no pain (n = 94, 12.7%) or intense pain (n = 88, 11.9%). The majority reported mild or moderate pain (n = 558, 75.4%). On multivariate analysis adjusted on gestational age, increasing initial [odds ratio (OR) 1.25, 95% confidence interval (CI) 1.06-1.47] or total dose (OR 1.15, 95% CI 1.05-1.26) of misoprostol taken were independent factors associated with risk of more pain. When adjusting for gestational age, initial dose of misoprostol (OR 1.69, 95% CI 1.45-2.66) and pain experienced (OR 3.58, 95% CI 2.82-4.55) were significantly associated with higher risk of CAI while API (OR 0.52, 95% CI 0.36; 0.75) was negatively associated. CONCLUSIONS: Most of the women received an APP, but not all used it. API and gestational age were not related to different risks of more pain following MToP, whereas history of at least one child showed a negative association. Higher doses of misoprostol were strongly associated with both pain and CAI. API was associated with a decreased risk of CAI.

RESUMO

The aim of our study was to evaluate the feasibility and efficiency of delayed ovarian stimulation and metaphase II oocyte banking for fertility preservation after fertility-impairing treatment regardless of the initial disease. We conducted a cohort study based on population of women < 40 years of age with diminished ovarian reserve caused by fertility-impairing treatment (n = 129). Three groups of women were compared according to the type of initial disease: hematological malignancies, solid tumors, and benign diseases. The primary endpoint was the number of metaphase II oocytes collected per woman. We studied the cumulative live-birth rate per cycle with fertilized metaphase II oocyte, for women who wanted to conceive. We studied 245 delayed controlled ovarian stimulation cycles in 129 women: 201 for fertility preservation and 44 for in vitro fertilization and fresh embryo transfers. The number of metaphase II oocytes collected per woman after banking was similar in the three groups, with a mean of 10.7 ± 4.6, 12.3 ± 9.1, and 10.1 ± 7.6 metaphase II oocytes (p = 0.46), respectively. In the subgroup of women who wanted to conceive, the cumulative live birth rate per woman was 38%, with 8 live births for these 21 women. After fertility-impairing treatment, practitioners should discuss a fertility preservation procedure for banking metaphase II oocytes.

RESUMO

Protein modification by SUMO (small ubiquitin-related modifier) has emerged as an essential regulatory mechanism in eukaryotes. Even though the molecular mechanisms of SUMO conjugation/deconjugation are conserved, the number of SUMO machinery components and their degree of conservation are specific to each organism. In the present paper, we show data contributing to the notion that the four expressed Arabidopsis SUMO paralogues, AtSUMO1, 2, 3 and 5, have functionally diverged to a higher extent than their human orthologues. We have explored the degree of conservation of these paralogues and found that the surfaces involved in E1-activating enzyme recognition, and E2-conjugating enzyme and SIM (SUMO-interacting motif) non-covalent interactions are well conserved in AtSUMO1/2 isoforms, whereas AtSUMO3 shows a lower degree of conservation, and AtSUMO5 is the most divergent isoform. These differences are functionally relevant, since AtSUMO3 and 5 are deficient in establishing E2 non-covalent interactions, which has not been reported for any naturally occurring SUMO orthologue. In addition, AtSUMO3 is less efficiently conjugated than AtSUMO1/2, and AtSUMO5 shows the lowest conjugation level. A mutagenesis analysis revealed that decreases in conjugation rate and thioester-bond formation are the result of the non-conserved residues involved in E1-activating enzyme recognition that are present in AtSUMO3 and 5. The results of the present study support a role for the E1-activating enzyme in SUMO paralogue discrimination, providing a new mechanism to favour conjugation of the essential AtSUMO1/2 paralogues.

RESUMO

INTRODUCTION: The aim of our study was to carry out a national survey of French practitioners to evaluate (i) their diagnostic criteria for making a diagnosis of unexplained infertility (UEI) and (ii) their management strategy when facing UEI. MATERIALS AND METHOD: An online questionnaire comprising ten multiple-choice questions was sent by mail to French reproductive practitioners in 80 fertility centres. RESULTS: The response rate was 59.6% (195/327). Post coital testing was always or often prescribed by 14.8% of respondents (n = 36). Chlamydia trachomatis testing was never prescribed by 31.7% (n = 59) of them, 30.2% prescribed a pelvic MRI in cases of UEI and 18.4% (n = 33) always or often performed laparoscopy. For 87.6% (n = 169), advanced maternal age was always or often an indication of first-line IVF, with an average threshold of 37.4 years. For 68.6% (n = 129), diminished AMH was an indication for first-line IVF, with an average AMH threshold of 1.2 ng/ml. With respect to the management of UEI, we did not observe a consensus between the strategies of 2 to 6 intrauterine insemination cycles before IVF or IVF as the first-line treatment. CONCLUSION: There is no consensus in France on what tests should or should not be carried out to conclude UEI, and there is also no consensus on the management of UEI. UEI is one of the top 10 priorities for future infertility research. The diagnostic criteria must be standardized to enable the comparison of studies on this topic as well as to improve the translation of research into clinical practice.

RESUMO

OBJECTIVE: This study aim was to examine the success rate of simple needle aspiration for acute Bartholin's gland abscess and compare it to incision and drainage treatment. STUDY DESIGN: This was a non-randomised prospective study conducted at the academic Hospital of La Conception, Marseille, France. We included 202 women who presented with acute Bartholin's gland abscess between June 2013 and October 2017. The study cohort was subdivided into two treatment groups, simple needle aspiration (134 women) or incision and drainage (42 women), according to the women's preference. Success was considered as the absence of surgical treatment within one year of the initial treatment. RESULTS: The success rate was 68/134 (51% (95% CI: 42-59%)) in the simple needle aspiration group and 25/42 (60%) in the incision drainage group (RR: 0.85, 95% CI: 0.63-1.15, P = 0.3). Among 122/134 (91%) women who completed the satisfaction survey, 99/122 (81%) were satisfied with the simple needle aspiration. CONCLUSIONS: Simple needle aspiration can be offered as first-line treatment for acute Bartholin's gland abscess. Simple needle aspiration can be performed as an outpatient procedure without general anesthesia avoiding surgical treatment in half of the cases one-year post- simple needle aspiration.

RESUMO

The objective of this study was to investigate the feelings and experiences of infertile women with deep infiltrating endometriosis during and after a first pregnancy achieved by in-vitro fertilization (IVF). We conducted a qualitative monocentric study between May and November 2020. Semi-structured interviews were undertaken with infertile women with deep infiltrating endometriosis who achieved a first pregnancy by IVF and delivered at least two years prior to the interview. Data analysis was performed using an inductive approach to identify recurrent categories and themes. Fifteen interviews were conducted to reach data saturation. Pregnancy appeared to improve all components of the experience of endometriosis that were explored (psychological and physical well-being, social relationships, professional life, and sexuality). This improvement was only temporary and all symptoms and negative aspects of the women's quality of life reappeared after a variable period.

RESUMO

OBJECTIVE: To describe and assess the feasibility of a novel surgical technique (pneumovaginoscopy) for performing vaginal surgery. DESIGN: Video of a single surgical procedure. SETTING: A university hospital. PATIENT(S): A 42-year-old woman, gravida 2 para 2, presented with chronic pelvic pain. Vaginal examination revealed a 4-cm spherical mass bulging through her posterior vaginal wall. Magnetic resonance imaging identified this mass as either a subserosal pedunculated uterine fibroid (type 7 according to the FIGO classification) or an ectopic fibroid of the posterior vaginal wall (type 8). INTERVENTION(S): The whole procedure was performed using pneumovaginoscopy. The GelPOINT V-Path (Applied Medical, Rancho Santa Margarita, California) which is the device most often used to perform transvaginal natural orifice transluminal endoscopic surgical procedures, was introduced into the vagina to create a pneumovagina. Monopolar scissors were used to create an incision through the posterior vaginal wall to reach the fibroid. Myomectomy was performed using traction movements of the fibroid associated with the dissection of the capsule. The absence of a uterine pedicle at the end of the myomectomy was in favor of an ectopic fibroid of the vagina (type 8 of the FIGO classification). The vaginal defect was closed with interrupted sutures using the access points on the GelPOINT. MAIN OUTCOME MEASURE(S): The procedure was easily and efficiently performed using the pneumovaginoscopy technique and lasted less than an hour. The patient was discharged on postoperative day 1 without any postoperative complications. She was symptom-free at her 2-month postoperative visit. RESULT(S): Compared to the classical vaginal approach, pneumovaginoscopy improves visualization through targeted lighting and close-up vision. This technique is particularly interesting in cases where the vaginal opening is narrow and for lesions located in the upper half of the vagina. Because of the unusual expansion of the vagina, increased caution is required to avoid bladder or rectal injuries. CONCLUSION(S): Pneumovaginoscopy is a novel technique that can be performed for vaginal pathologies with the same device used for transvaginal natural orifice transluminal endoscopic surgery. We described this technique and assessed its feasibility.

RESUMO

INTRODUCTION: On March 14, 2020, France has entered into stage 3 of the COVID-19 pandemic. The French National Health Agency (Haute Autorité de Santé) has urgently recommended the use of medical abortion at home between 7 and 9 weeks of gestation and telemedicine for medical abortion consultations. The main objective of this study was to assess whether the emergency measures undertaken for the management of abortions during the COVID-19 pandemic led to practice changes, and to obtain practitioners' opinions regarding the continuation of these measures. MATERIAL AND METHODS: This was a retrospective, quantitative, online self-administered survey from August 6, 2020 to October 2, 2020, aimed at health workers performing abortions (midwives, general practitioners, gynecologists obstetricians and medical gynecologists) in the South and Corse regions in France. RESULTS: Among the 124 practitioners included, 59/77 (76.6 %) offered medical abortion at home between 7 and 9 weeks of gestation and 61/89 (68.5 %) of them wished to carry on this practice. 55/123 (44.7 %) practitioners offered telemedicine for medical abortion at home and 71/115 (61.7 %) of them wished to carry on this practice. DISCUSSION: The emergency measures implemented by the the French National Health Agency (Haute Autorité de Santé) for medical abortion are approved and followed by the majority of health workers performing abortions in the South and Corse regions. This measure may be extended out of the COVID-19 epidemic.
