RESUMO
INTRODUCTION: Obstetric anal sphincter injuries (OASIs) at the time of childbirth can lead to serious consequences including anal incontinence, dyspareunia, pain and rectovaginal fistula. These types of lesions and their incidence have been well studied after cephalic presentation deliveries, but no publications have specifically addressed this issue in the context of vaginal breech delivery. The goal of our study was to evaluate the incidence of OASIs following breech deliveries and compare it with cephalic presentation births. METHODS: This was a retrospective cohort study involving 670 women. Of these, 224 and 446 had a vaginal birth of a fetus in the breech (breech group) and cephalic (cephalic group) presentations respectively. Both groups were matched for birthweight (± 200 g), date of delivery (± 2 years) and vaginal parity. Main outcome of interest was to evaluate the incidence of OASIs following breech vaginal birth compared to cephalic vaginal births. Secondary endpoints were the incidence of intact perineum or first-degree tear, second-degree perineal tear and rates of episiotomies in each group. RESULTS: There was no statistically significant difference in OASIs incidence between the breech and cephalic groups (0.9% vs. 1.1%; RR 0.802 (0.157; 4.101); p = 0.31). There were more episiotomies in the breech group (12.5% vs. 5.4%, p = 0.0012) and the rate of intact or first-degree perineum was similar in both groups (74.1% vs. 75.3%, p = 0.7291). A sub-analysis excluding patients with episiotomy and history of OASIs did not show any statistically significant difference either. CONCLUSION: We did not demonstrate a significant difference in the incidence of obstetric anal sphincter injuries between women who had a breech vaginal birth compared to cephalic.

INTRODUCTION AND HYPOTHESIS: Our purpose was to compare the prevalence of urinary incontinence (UI) 3 and 12 months after vaginal vs cesarean delivery of twins after 34 weeks of gestation. METHODS: This was a multicenter prospective cohort study conducted at 172 French maternity units and included 2812 primiparous women with twins with no prior history of UI. Participants were enrolled at the time of delivery and followed up to 12 months postpartum. The primary outcome was the prevalence of UI, both stress and urge, 3 months postpartum, based on the patient reporting any frequency of urine leakage to the first question of the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF). The Pelvic Floor Distress Inventory - Short Form 20 (PFDI-20), Pelvic Floor Impact Questionnaire - Short Form 7 (PFIQ-7), Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12), and Medical Outcome Study Short Form-12 (SF-12) were also used. RESULTS: The ICIQ-SF was completed by 1155 (39.8%) and 800 (27.5%) women, respectively, at 3 and 12 months postpartum; 556 (48%) had delivered vaginally and 599 (52%) by cesarean section. The prevalence of UI at 3 months was 26% overall and was significantly higher in the vaginal delivery group at both 3 months (35% vs 17% in the cesarean group, p < 0.0001) and 12 months postpartum (38% vs 24%, p < 0.0001). UI was predominantly stress or mixed. The risk factors for UI at 3 months, determined by multivariate modeling, were vaginal delivery [odds ratio (OR) 3.073, 95% confidence interval (CI) 2.3-4.105, p < 0.0001) and body mass index >25 in early pregnancy (OR 1.620, 95% CI 1.188-2.209, p = 0.0023). CONCLUSIONS: Vaginal delivery is a risk factor for UI at 3 months after twin birth.

INTRODUCTION AND HYPOTHESIS: To compare the impact of vaginal delivery (VD) versus cesarean section (CS) on the pelvic floor in twin primiparae at 3 and 12 months postpartum. METHODS: This comparative multicenter prospective cohort from a large French national cohort study consisted of primiparas who gave birth to live twins after 34 weeks of gestation. The primary end point was the postnatal urinary incontinence rate 3 months postpartum. The secondary end points were the pelvic floor dysfunction (PFD) at 3 and 12 months based on PFDI-20, PFIQ-7, PISQ-12, and SF-12 responses. RESULTS: A total of 2812 patients in 172 French maternity units were recruited between February 2014 and March 2015: 1076 (38%) responded at 3 and 12 months (61% at 3 months); 1155 were analyzed at 3 months (556 VD and 599 CS) and 800 at 12 months (394 VD and 406 CS). VD was associated with more symptoms at 3 months [median PFDI-20 score 25/300 (8-50) vs. 17/300 (4-36) after CS; p < 0.0001]. Vaginal bulge was more frequently reported after VD (9 vs. 4%; p = 0.0015). Abdnormal PFD-related quality-of-life scores (scores > 0) were more frequent after VD at 3 months (58 vs. 42%; p < 0.0001) and 12 months (57 vs. 43%; p = 0.0020), indicating greater discomfort. However, SF-12 scores were higher after VD [56 (53-59) vs. 55 (51-58)] at 12 months, indicating better general quality of life. CONCLUSIONS: Mode of delivery is significantly associated with pelvic organ prolapse symptoms 3 months postpartum, which regress by 12 months, probably because of the known spontaneous postnatal improvement of PFDs.

BACKGROUND: Post-partum haemorrhage (PPH) is one of the major obstetric complications and remains a cause of avoidable maternal mortality and morbidity. AIMS: The aims of this study were to assess the success and practicability of a Bakri™ balloon intrauterine tamponade for PPH and evaluate the predictive factors for success. MATERIALS AND METHODS: Women who received the Bakri™ balloon secondary to uterine atony and subsequent failure of routine drug treatment were identified at 6 hospital sites. Demographic, obstetric and specific factors in regard to the Bakri™ balloon use were recorded. Factors predictive of Bakri™ balloon success were evaluated. RESULTS: Intrauterine Bakri™ balloon tamponade was used in 36 women with uterine atony of which 28 received the balloon treatment after vaginal delivery: more than 50% of women (16/28) presented with PPH with blood loss > 1000 mL (mean blood loss: 1130 mL). Two balloon insertions failures were identified. Bakri balloon success was 100% for women with bleeding < 1000 mL. Twenty-five women (69%) did not require invasive treatment; seven (19%) required arterial embolisation and four (11%) surgical management. No short-term complication was observed after balloon insertion. CONCLUSION: The use of the Bakri™ balloon method, if undertaken early, is effective for the management of PPH with uterine atony (100% success compared to 69% overall success rate). Intrauterine balloon tamponade should included in PPH management guidelines.

INTRODUCTION: The prevalence of Caesarean delivery is rising steadily worldwide, and it is important to identify its future impact on fertility. A number of articles have been published on this subject, but the impact of Caesarean section on reproductive outcomes is still under debate, and none of these articles focus exclusively on frozen blastocysts. OBJECTIVE: The aim of this study was to evaluate the impact of a previous Caesarean delivery compared with a previous vaginal delivery on the chances of a live birth following the transfer of one or more frozen embryos at the blastocyst stage. METHODS: This was a retrospective, bicentric study at the University Hospitals of Nîmes and Montpellier, conducted between January 1st, 2016 and February 1st, 2021. Three hundred and ninety women with a history of childbirth and a transfer of one or more frozen embryos at blastocyst stage were included in the analysis. The primary outcome was the number of live births. Secondary outcomes were: the rate of positive HCG, miscarriage, ectopic pregnancy and clinical pregnancy, as well as the live birth rate according to the presence or absence of an isthmocele. RESULTS: Of the 390 patients included, 118 had a previous Caesarean delivery and 272 a vaginal delivery. No statistically significant differences were found for the primary (pâ¯=â¯0.9) or secondary outcomes. A trend towards lower live birth rates was observed in patients with isthmoceles, but this did not reach significance (p>0.9). On the other hand, transfers were more often described as difficult in the Caesarean delivery group (pâ¯=â¯0.011). CONCLUSION: Our study found no effect of previous Caesarean delivery on the chances of live birth after transferring one or more frozen blastocysts. However, further prospective studies are needed to confirm these results.

Birth weight (BW) is higher after frozen embryo transfer (FET) than after fresh embryo replacement. No study has compared the BW of siblings conceived using the same oocyte/embryo cohort. The aim of this study was to determine whether the freezing-thawing procedure is involved in such difference. Multicenter study at Montpellier University Hospital, Clinique Ovo, Canada and Grenoble-Alpes University Hospital. The first cohort (Fresh/FET) included in vitro fertilization (IVF) cycles where the older was born after fresh embryo transfer (n = 158) and the younger after transfer of frozen supernumerary embryos (n = 158). The second cohort (FET/FET) included IVF cycles where older and younger were born after FET of embryos from the same cohort. The mean adjusted BW of the FET group was higher than that of the fresh group (3508.9 ± 452.4 g vs 3237.7 ± 463.3 g; p < 0.01). In the FET/FET cohort, the mean adjusted BW was higher for the younger by 93.1 g but this difference is not significant (3430.2 ± 347.6 g vs 3337.1 ± 391.9 g; p = 0.3789). Our results strongly suggest that cryopreservation is directly involved in the BW variation. Comparing BW difference between Fresh/FET cohort and FET/FET one, it suggests that parity is not the only responsible, increasing the role of cryopreservation step in BW variation.

BACKGROUND: Several studies suggest a decrease in sperm quality in men in the last decades. Therefore, the aim of this work was to assess the influence of male factors (sperm quality and paternal age) on the outcomes of conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). METHODS: This retrospective study included all couples who underwent IVF or ICSI at Montpellier University Hospital, France, between 1 January 2010 and 31 December 2015. Exclusion criteria were cycles using surgically retrieved sperm or frozen sperm, with pre-implantation genetic diagnosis or using frozen oocytes. The primary outcomes were the blastulation rate (number of blastocysts obtained at day 5 or day 6/number of embryos in prolonged culture at day 3) and the clinical pregnancy rate. The secondary outcomes were the fertilization and early miscarriage rates. RESULTS: In total, 859 IVF and 1632 ICSI cycles were included in this study. The fertilization rate after ICSI was affected by oligospermia. Moreover, in ICSI, severe oligospermia (lower than 0.2 million/ml) led to a reduction of the blastulation rate. Reduced rapid progressive motility affected particularly IVF, with a decrease of the fertilization rate and number of embryos at day 2 when progressive motility was lower than 32%. Paternal age also had a negative effect. Although it was difficult to eliminate the bias linked to the woman's age, pregnancy rate was reduced in IVF and ICSI when the father was older than 51 and the mother older than 37 years. CONCLUSIONS: These results allow adjusting our strategies of fertilization technique and embryo transfer. In the case of severe oligospermia, transfer should be carried out at the cleaved embryo stage (day 2-3) due to the very low blastulation rate. When the man is older than 51 years, couples should be aware of the reduced success rate, especially if the woman is older than 37 years. Finally, promising research avenues should be explored, such as the quantification of free sperm DNA, to optimize the selection of male gametes.
CONTEXTE: De nombreuses données suggèrent une altération des paramètres spermatiques ces dernières décennies. Le but de ce travail est d'évaluer l'impact de facteurs masculins tels la qualité du sperme et l'âge paternel sur les résultats en fécondation in vitro classique (FIVc) et en fécondation in vitro avec injection intra-cytoplasmique de spermatozoïde (ICSI). MATÉRIELS ET MÉTHODES: L'étude a porté sur l'ensemble des couples ayant fait l'objet d'une tentative de FIVc ou d'ICSI entre le 1er janvier 2010 et le 31 décembre 2014 au CHU de Montpellier. Les critères d'exclusion ont été les tentatives avec utilisation de spermatozoïdes prélevés chirurgicalement ou de sperme congelé, les cycles avec diagnostic pré-implantatoire et les cycles avec ovocytes congelés. Au total, 859 ponctions de FIVc et 1632 ponctions d'ICSI ont été incluses dans l'étude. RÉSULTATS: En ICSI, le taux de fécondation est affecté par l'oligospermie. Par ailleurs, une oligospermie extrême (inférieure à 0,2 M/ml) entraîne une diminution du taux de blastulation. La mobilité progressive avant préparation a plus d'impact en FIVc, où les taux de fécondation et le nombre d'embryons obtenus à J2 vont être plus bas lorsque la mobilité progressive est inférieure à 32%. Même s'il est difficile d'éliminer le biais lié à l'âge de la partenaire, il semblerait qu'il y ait une diminution du taux de grossesse en FIVc et en ICSI à partir de 51 ans chez l'homme avec une partenaire âgée de plus de 37 ans. CONCLUSION: Ces résultats permettront essentiellement d'ajuster nos stratégies de choix de technique de mise en fécondation et de transfert. Pour les oligospermies extrêmes, il semble préférable de proposer un transfert précoce au stade embryon clivé (J2 - J3) car le taux de blastulation est très réduit dans ce cas. Lorsque l'homme est âgé, il faudra également informer le couple de la diminution des taux de réussite, d'autant plus si sa partenaire a plus de 37 ans. Enfin, différentes pistes prometteuses de recherche sont encore à explorer, comme le dosage de l'ADN libre spermatique afin d'optimiser la sélection des gamètes masculins et ainsi améliorer les résultats en AMP.
