[First-line management of infertile couple. Guidelines for clinical practice of the French College of Obstetricians and Gynecologists 2022]. / Prise en charge de première intention du couple infertile : mise à jour des RPC 2010 du CNGOF.

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.

Oocyte Vitrification for Fertility Preservation in Women with Benign Gynecologic Disease: French Clinical Practice Guidelines Developed by a Modified Delphi Consensus Process.

International guidelines are published to provide standardized information and fertility preservation (FP) care for adults and children. The purpose of the study was to conduct a modified Delphi process for generating FP guidelines for BGD. A steering committee identified 42 potential FP practices for BGD. Then 114 key stakeholders were asked to participate in a modified Delphi process via two online survey rounds and a final meeting. Consensus was reached for 28 items. Among them, stakeholders rated age-specific information concerning the risk of diminished ovarian reserve after surgery as important but rejected proposals setting various upper and lower age limits for FP. All women should be informed about the benefit/risk balance of oocyte vitrification-in particular about the likelihood of live birth according to age. FP should not be offered in rASRM stages I and II endometriosis without endometriomas. These guidelines could be useful for gynecologists to identify situations at risk of infertility and to better inform women with BGDs who might need personalized counseling for FP.

Evaluation of fertility after operative hysteroscopy to remove retained products of conception.

Evaluation of fertility after operative hysteroscopy to remove retained products of conception. OBJECTIVE: To study fertility after operative hysteroscopy for the management of prolonged trophoblastic retention, and the complications of this procedure. STUDY DESIGN: Retrospective cohort in a university hospital. RESULTS: 115 patients underwent operative hysteroscopy for the treatment of prolonged post-partum and post-abortum retention between January 2008 and December 2011. Of the 115 patients included in this study, 53 desired a postoperative pregnancy. Using the survival model, the conception rate was 71.1% (95%CI; 58.1-82.9) at 6 months and 83.5% (95%CI; 71.8-92.2) at 1year. The overall rate of intraoperative complications was 15%. The rate of complications≥grade 3 was 5%. Logistic regression analysis showed that only retentions of greater than 25mm were associated with complications generally (aOR=7.4; 95%CI; 2.3-24.5) and with Clavien-Dindo complications≥grade 3 (OR=27.2; 95%CI; 2.8-263). CONCLUSION: The management of prolonged retention by operative hysteroscopy allows the preservation of future fertility. There are more complications when the retentions are >25mm.

Fertility after uterine artery embolization for symptomatic multiple fibroids with no other infertility factors.

OBJECTIVES: To evaluate the fertility of women eligible for surgical multiple myomectomy, but who carefully elected a fertility-sparing uterine artery embolization (UAE). METHODS: Non-comparative open-label trial, on women ≤40 years, presenting with multiple symptomatic fibroids (at least 3, ≥3 cm), immediate pregnancy wish, and no associated infertility factor. Women had a bilateral limited UAE using tris-acryl gelatin microspheres ≥500 µm. Fertility, ovarian reserve, uterus and fibroid sizes, and quality of life questionnaires (UFS-QoL) were prospectively followed. RESULTS: Fifteen patients, aged 34.8 years (95%CI 32.2-37.5, median 36.0, q1-q3 29.4-39.5) were included from November 2008 to May 2012. During the year following UAE, 9 women actively attempting to conceive experienced 5 live-births (intention-to-treat fertility rate 33.3%, 95%CI 11.8%-61.6%). Markers of ovarian reserve remained stable. The symptoms score was reduced by 66% (95%CI 48%-85%) and the quality of life score was improved by 112% (95%CI 21%-204%). Uterine volume was reduced by 38% (95%CI 24%-52%). Women were followed for 43.1 months (95%CI 32.4-53.9), 10 live-births occurred in 8 patients, and 5 patients required secondary surgeries for fibroids. CONCLUSION: Women without associated infertility factors demonstrated an encouraging capacity to deliver after UAE. Further randomized controlled trials comparing UAE and myomectomy are warranted. KEY POINTS: • Women without infertility factors showed an encouraging delivery rate after UAE. • For women choosing UAE over abdominal myomectomy, childbearing may not be impaired. • Data are insufficient to definitively recommend UAE as comparable to myomectomy. • Further randomized trials comparing fertility after UAE or myomectomy are warranted.

Safeguarding Fertility With Whole Ovary Cryopreservation and Microvascular Transplantation: Higher Follicular Survival With Vitrification Than With Slow Freezing in a Ewe Model.

BACKGROUND: In young women, ovarian cortex cryopreservation before gonadotoxic chemotherapy and its avascular grafting after cancer healing permitted fertility restoration. However, ischemia reduced the grafts' lifespan. Microvascular transplantation of cryopreserved whole ovary may allow immediate revascularization, ensuring better fertility preservation, but the best cryopreservation method is unknown. We aimed to compare slow freezing and vitrification of whole ovary for fertility preservation purposes, in an ewe model. METHODS: Twelve ewes were allocated at random to slow freezing (n = 6) or vitrification group (n = 6). Ewes' left ovary was removed and cryopreserved. Dimethyl sulfoxide 2 M was used as cryoprotector for slow freezing. Vitrification was obtained using increasing concentrations of a vitrification solution of the latest generation (VM3) and gradual temperature lowering to minimize toxicity. After a month, the right ovary was removed, the left ovary was thawed/warmed, and its vessels were anastomosed to the right pedicle. Fertility and ovarian function were assessed for 3 years. Ovarian follicles in native and transplanted ovaries were counted and compared at study completion. RESULTS: Hormonal secretion resumed in all ewes of both groups. One ewe of the slow-freezing group delivered healthy twins 1 year 9 months and 12 days after transplantation. Estimated whole follicle survival was very low in both groups but significantly higher after vitrification than after slow freezing (0.3% ± 0.5% vs 0.017% ± 0.019%, respectively; p < 0.05). CONCLUSIONS: Further progress is needed before whole-ovary cryopreservation can be considered an option for safeguarding fertility. Whole ovary vitrification provides better follicular survival compared to slow freezing and may be a valuable cryopreservation option.

Associations between Individual and Combined Polymorphisms of the TNF and VEGF Genes and the Embryo Implantation Rate in Patients Undergoing In Vitro Fertilization (IVF) Programs.

BACKGROUND: A multiple pregnancy is now considered to be the most common adverse outcome associated with in vitro fertilization (IVF). As a consequence, the identification of women with the best chances of embryo implantation is a challenge in IVF program, in which the objective is to offer elective single-embryo transfer (eSET) without decreasing the pregnancy rate. To date, a range of hormonal and clinical parameters have been used to optimize eSET but none have significant predictive value. This variability could be due to genetic predispositions related to single-nucleotide polymorphisms (SNPs). Here, we assessed the individual and combined impacts of thirteen SNPs that reportedly influence the outcome of in vitro fertilisation (IVF) on the embryo implantation rate for patients undergoing intracytoplasmic sperm injection program (ICSI). MATERIALS AND METHODS: A 13 gene polymorphisms: FSHR(Asn680Ser), p53(Arg72Pro), AMH(Ile49Ser), ESR2(+1730G>A), ESR1(-397T>C), BMP15(-9C>G), MTHFR1(677C>T), MTHFR2(1298A>C), HLA-G(-725C>G), VEGF(+405G>C), TNFα(-308A>G), AMHR(-482A>G), PAI-1(4G/5G), multiplex PCR assay was designed to genotype women undergoing ICSI program. We analyzed the total patients population (n = 428) and a subgroup with homogeneous characteristics (n = 112). RESULTS: Only the VEGF(+405G>C) and TNFα(-308A>G) polymorphisms impacted fertilization, embryo implantation and pregnancy rates. Moreover, the combined VEGF+405.GG and TNFα-308.AG or AA genotype occurred significantly more frequently in women with high implantation potential. In contrast, the VEGF+405.CC and TNFα-308.GG combination was associated with a low implantation rate. CONCLUSION: We identified associations between VEGF(+405G>C) and TNFα(-308A>G) polymorphisms (when considered singly or as combinations) and the embryo implantation rate. These associations may be predictive of embryo implantation and could help to define populations in which elective single-embryo transfer should be recommended (or, conversely, ruled out). However, the mechanism underlying the function of these polymorphisms in embryo implantation remains to be determined and the associations observed here must be confirmed in a larger, more heterogeneous cohort.

Genetic polymorphisms influence the ovarian response to rFSH stimulation in patients undergoing in vitro fertilization programs with ICSI.

INTRODUCTION: Obtaining an adequate number of high-quality oocytes is a major challenge in controlled ovarian hyperstimulation (COH). To date, a range of hormonal and clinical parameters have been used to optimize COH but none have significant predictive value. This variability could be due to the genetic predispositions of single-nucleotide polymorphisms (SNPs). Here, we assessed the individual and combined impacts of thirteen SNPs that reportedly influence the outcome of in vitro fertilisation (IVF) on the ovarian response to rFSH stimulation for patients undergoing intracytoplasmic sperm injection program (ICSI). RESULTS: Univariate analysis revealed that only FSHR, ESR2 and p53 SNPs influenced the number of mature oocytes. The association was statistically significant for FSHR (p=0.0047) and ESR2 (0.0017) in the overall study population and for FSHR (p=0.0009) and p53 (p=0.0048) in subgroup that was more homogeneous in terms of clinical variables. After Bonferroni correction and a multivariate analysis, only the differences for FSHR and ESR2 polymorphisms were still statistically significant. In a multilocus analysis, only the FSHR and AMH SNP combination significantly influenced oocyte numbers in both population (p<0.01). DISCUSSION: We confirmed the impact of FSHR and ESR2 polymorphisms on the IVF outcome. Furthermore, we showed for the first time that a p53 polymorphism (which is already known to impact embryo implantation) could influence the ovarian response. However, given that this result lost its statistical significance after multivariate analysis, more data are needed to draw firm conclusions. Only the FSHR and AMH polymorphism combination appears to influence mature oocyte numbers but this finding also needs to be confirmed. MATERIALS AND METHODS: A 13 gene polymorphisms: FSHR(Asn680Ser), p53(Arg72Pro), AMH(Ile49Ser), ESR2(+1730G>A), ESR1(-397T>C), BMP15(-9C>G), MTHFR1(677C>T), MTHFR2(1298A>C), HLA-G(-725C>G), VEGF(+405G>C), TNFα(-308A>G), AMHR(-482 A>G), PAI-1 (4 G/5 G), multiplex PCR assay was designed to genotype women undergoing ICSI program. We analyzed the overall study population (n=427) and a subgroup with homogeneous characteristics (n=112).

Adiponectin and leptin systems in human endometrium during window of implantation.

OBJECTIVE: To measure the expression of adiponectin, leptin, and their respective receptors in the human endometria of fertile women compared with women with unexplained recurrent implantation failure (IF) during the window of implantation. DESIGN: Controlled, prospective, clinical study. SETTING: Teaching hospital and university research laboratory. PATIENT(S): Thirty-one endometrial biopsies from women with IF and 19 fertile controls. INTERVENTION(S): Human endometrial biopsies. MAIN OUTCOME MEASURE(S): Gene and protein expression of endometrial biopsies. RESULT(S): Endometrial leptin expression was significantly lower in the IF group compared with fertile women. In contrast, leptin receptor (Ob-R) expression was higher in endometria of women with IF. Concerning the adiponectin system, adiponectin was expressed to the same extent in both groups. Conversely, the expression of its two receptors, AdipoR1 and AdipoR2, was reduced in endometria of women with IF compared with fertile women. CONCLUSION(S): Although progesterone resistance seems to be a common state of the endometrium in some human reproductive disorders, such as endometriosis or polycystic ovary syndrome, modification in leptin endometrial expression seems to be specific to IF. These results strongly suggest that changes in Ob-R and AdipoR expression profiles [1] should be implicated in the development of uterine receptivity, and [2] may therefore be potential new targets for prediction of IF.

Ovarian drilling for surgical treatment of polycystic ovarian syndrome: a comprehensive review.

This systematic literature review is intended to clarify and evaluate the results obtained by ovarian drilling as surgical treatment for polycystic ovarian syndrome (PCOS). Four databases were consulted (Medline at the National Library of Medicine, USA; Cochrane Library, UK; National Guideline Clearinghouse, USA; and the Health Technology Assessment Database, Sweden) and searched for 'polycystic ovary syndrome' plus 'drilling' in the title or abstract. The assessment criteria used to define the efficacy of the procedure were the rates of ovulation, clinical pregnancy and early miscarriage. Alternatives to surgical ovarian drilling were evaluated. This search produced 147 references, 81 of which met the selection criteria. This review of infertility management in women with PCOS indicates that ovarian drilling is a second-line treatment when treatment with clomiphene citrate fails to lead to conception. The benefits of ovarian drilling are that it does not induce either hyperstimulation syndrome or multiple pregnancies. It is concluded that ovarian drilling is an option in the management of female infertility associated with PCOS, especially as a second-line treatment after the failure of clomiphene citrate treatment.

Oestrogens inhibit interleukin 1beta-mediated nitric oxide synthase expression in articular chondrocytes through nuclear factor-kappa B impairment.

OBJECTIVES: To investigate the presence and functionality of oestrogen receptor alpha (ERalpha) in interleukin (IL)1beta-treated rabbit articular chondrocytes in culture, and to determine the mechanisms of 17beta oestradiol (E2) effects on IL1beta-induced inducible nitric oxide synthase (iNOS) expression. METHODS: The presence and functionality of ERalpha were investigated by immunocytochemistry and transient expression of an E2-responsive reporter construct. iNOS expression and production were determined by transient expression of a chimeric iNOS promoter-luciferase construct and protein immunoblotting. Nitric oxide (NO) production was determined by the Griess reaction. DNA-binding activities of nuclear factor-kappaB (NF-kappaB) and activated protein 1 were determined by electrophoretic mobility shift assay (EMSA)-ELISA assays. Nuclear translocation of p65 was studied by immunocytochemistry. RESULTS: ERalpha was identified in the nucleus of chondrocytes. ERalpha efficiently transactivated a transiently expressed E2-responsive construct. On IL1beta treatment, ERalpha partially diffused from its nuclear localisation into the cytoplasm and its transactivation ability was impaired. Nevertheless, E2, tamoxifen and raloxifene efficiently inhibited IL1beta-induced NO production (-34%, -31% and -36%, respectively). E2 decreased IL1beta-induced iNOS protein expression (-40%). Transient expression of an iNOS promoter construct strongly suggested that iNOS expression was inhibited at the transcriptional level, and EMSA-ELISA assays showed that E2 reduced (-60%) the IL1beta-induced p65 DNA-binding capacity. Finally, the p65 nuclear translocation induced by IL1beta was also strongly decreased by E2. CONCLUSIONS: Our data support a reciprocal antagonism between oestrogens and IL1beta, ultimately resulting in the decrease of cytokine-dependent NO production through transcriptional inhibition of iNOS expression. This effect was associated with selective inhibition of p65 DNA binding and nuclear translocation.
