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

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

Strains Marseille-Q5893 (= CSUR Q5893 = CECT 30496) and Marseille-Q5883 (= CSUR Q5883 = CECT 30497) were isolated from vaginal samples using the culturomics approach. The 16S rRNA gene sequences of each strain were sequenced and then compared by BLASTn to the NCBI database. Strains Marseille-Q5893 and Marseille-Q5883 were most closely related to Anaerococcus obesiensis and Finegoldia magna, with identities of 98.5% and 90.0%, respectively. Strain Marseille-Q5893 is strictly anaerobic, while strain Marseille-Q5883 is facultative anaerobic. Both strains are Gram-positive, coccus-shaped, oxidase- and catalase-negative. The most abundant fatty acid for both strains is hexadecanoic acid, followed by 9-octadecenoic acid and tetradecanoic acid. Strain Marseille-Q5893 has a genome size of 1,831,271 bp with a G+C content of 29.4 mol%, whereas strain Marseille-Q5883 has a genome of 1,997,945 bp with a 33.6 mol% G+C content. The genomic comparison of closely related species with strains Marseille-Q5893 and Marseille-Q5883 showed that all digital DNA-DNA hybridization (dDDH) and orthologous average nucleotide identity (OrthoANI) values were lower than the published species thresholds (70% and 95-96%, respectively). Based on these data, we conclude that strain Marseille-Q5893 belongs to a new species in the family Peptoniphilaceae and strain Marseille-Q5883 belongs to a new genus in the family Peptostreptococcaceae. For these two new bacterial species, the names Anaerococcus ihuae sp. nov. and Mediannikoviicoccus vaginalis gen. nov., sp. nov., were proposed.

RESUMO

BACKGROUND: Previous quantitative studies have shown a reduced quality of life in patients treated for craniopharyngioma (CP). However, few have assessed their sexual quality of life and other issues related to patient intimacy have not yet been addressed. Standardized questionnaires limit the approach to sexuality and the exploration of patient experiences. A qualitative study, which allows in-depth analysis, may represent an interesting approach to explore intimacy in women with a history of CP. OBJECTIVE: To assess the impact of a CP history on femininity and relationships in women. DESIGN AND PATIENTS: A qualitative study with semi-structured interviews was conducted with 15 adult women treated for CP during childhood, adolescence or at childbearing age up to 40 years of age. Interviews were audio recorded, anonymized and transcribed literally. Data analysis was carried out with an inductive approach according to the grounded theory method. RESULTS: Three main themes were identified: (a) apparent changes leading to altered self-perception that may impact on femininity and generate lower self-esteem; (b) managing the hidden disabilities of the disease inducing a need for permanent control; and (c) building parenthood and couple relationships: coping with sexual dysfunction and infertility. CONCLUSIONS: Our study highlighted alterations in self-perception and femininity due to body change and disability resulting from CP treatment, impacting both couple and social relationships. Interviewing women who underwent CP surgery at different ages highlighted specific needs and different expectations of medical professionals which emphasize the importance of offering both global and personalized care.

RESUMO

PURPOSE: To determine the use of a new specialized E-Meeting for Complex Cases in Oncofertility by fertility preservation specialists (FPSs) MATERIAL AND METHODS: We present 3 years of activity of the E-Meeting for Complex Cases in Oncofertility, a new tool created in September 2016 which allows national oncofertility experts to share viewpoints about challenging cases for which they do not have experience or sufficient data in order to provide them an emergency advice within 48 h. Second, a survey was conducted to evaluate the use of this e-meeting for participating FPSs. RESULTS: One hundred and four experts have joined the e-meeting since its set-up, and 109 challenging cases have been submitted. The mean age of the patients was 22.4 ± 8.9 years, and 87.0% were female. Each submitted case received on average of 1.8 ± 1.1 different strategies for FP and the opinions of 7.1 ± 3.4 experts. Among the FPSs who submitted cases, seeking opinions from other FPSs allowed them to confirm their care plan (N = 49, 84.4%), to offer different options to their patients (N = 34, 58.6%), and to compare their practices with those of other specialists (N = 23, 39.6%). All respondents reported a self-perceived improvement in their practice of oncologic FP (n = 80, 100.0%). CONCLUSION: Specific attention should be paid to challenging cases for which the experiences of only a few individuals exist. Enhancing communication between FPSs through oncofertility networks, pooling experiences, and collecting the most complex cases is required to improve the management of these patients.

RESUMO

RESEARCH QUESTION: Is polycyclic aromatic hydrocarbon (PAH) exposure associated with the reproductive outcomes of IVF treatment? DESIGN: A prospective, small-scale monocentric cohort study of couples who underwent IVF treatment between January 2018 and June 2019. Both members of each couple answered a questionnaire on PAH exposure and provided urine samples to measure urinary 1-hydroxypyrene (1-OHP) the day before oocyte retrieval and semen collection for fertilization. To assess the specific PAH exposure of gamete cells, immunostaining was conducted on both spermatozoa and granulosa cells obtained during IVF with an anti-benzo(a)pyrene diol epoxide (BPDE) monoclonal antibody that recognizes BDPE-DNA adducts. To assess DNA damage, a comet assay on spermatozoa was conducted. The PAH exposure was compared between couples who had positive HCG and couples who had negative HCG on day 14 after embryo transfer. RESULTS: Eighteen couples were included. The mean 1-OHP level in women whose HCG tests were positive (n = 6) was significantly lower than that in women with negative HCG tests (0.098 [0.042-0.170] versus 0.177 [0.067-0.812] µg/g creatinine; P = 0.048). The presence of BPDE-DNA adducts in granulosa cells of women with a negative (29.7 [16.2-57.5] arbitrary units) or positive HCG test (20.3 [9.3-23.3] arbitrary units) were not significantly different (P = 0.092). The urinary 1-OHP levels of men and BPDE-DNA adducts in spermatozoa showed no differences between groups. CONCLUSIONS: This exploratory research should encourage further studies to determine the effect of women's exposure to PAHs on reproductive outcomes of IVF treatment.

RESUMO

PURPOSE: Surgical indications for pituitary tumors during pregnancy are rare, and are derived from a balance between expected benefits, particularly for maternal benefits, and anesthetic/surgical risks. METHODS: A literature review was performed to define the optimal surgical indications for pituitary adenomas (PA) and other pituitary tumors during pregnancy. RESULTS: Main benefits are expected in case of critical visual impairment and/or life-threatening endocrine disturbances. Multidisciplinary patient management is systematically required although nonobstetric surgery presents a reasonable risk during pregnancy. The risks of congenital malformation during the first trimester and those of premature birth during the third trimester make the second trimester the optimal period for surgery. In prolactin-secreting, nonsecreting, GH- and TSH-secreting PAs, transsphenoidal surgery (TS) is recommended in cases involving severe visual impairment, characterized by severe visual field deficit, visual acuity impairment, and abnormal optical coherence tomography findings, and when no other medical alternatives are possible and/or sufficient. Uncontrolled and severe Cushing's disease (CD) during pregnancy increases both maternal and fetal morbimortality, thus justifying TS or sometimes dopamine agonist therapy as a safer alternative. Finally, metyrapone, ketoconazole, or bilateral adrenalectomy could be recommended in certain cases after the failure of medical therapies and/or TS. Surgery is also required for suprasellar meningiomas, craniopharyngiomas, and pituitary cysts in the case of severe visual deficit. CONCLUSION: Surgical indications for pituitary tumors are rare during pregnancy; therefore, surgery should be avoided when possible. Further, the second trimester should be considered as the optimal surgical period. Severe visual disturbance and uncontrolled CD are the main surgical indications during pregnancy.

RESUMO

In animals, research in the past two decades has demonstrated the strong involvement of the endocannabinoid system (ECS) in numerous steps of the reproductive process, including ovarian physiology. Reproductive lifespan is closely related to the number of nongrowing ovarian follicles, called ovarian reserve (OR), which is definitively established during foetal life. Thus, OR damage may lead to poor reproductive outcomes and a shortened reproductive lifespan. We investigated whether prenatal ECS modulation had an effect on the OR at different ages in the rat offspring. Four groups of gestating female rats (F0) were exposed to the CB1-/CB2-receptor agonist WIN55212 (0.5 mg/kg), the CB1R inverse agonist SR141716 (3 mg/kg) or Δ9THC (5 mg/kg) and were compared to negative control groups. OR was histologically assessed at different postnatal timepoints (F1 individuals): postnatal day (PND) 6, PND40 and PND90. At PND6, prenatal exposure had no effect on OR. In the young adult group (PND90) exposed during gestation to WIN55212, we observed a CB1R-mediated delayed OR decrease, which was reversed by prenatal CB1R blockade by SR141716. Conversely, after prenatal SR141716 exposure, we observed higher OR counts at PND90. RT-PCR experiments also showed that prenatal ECS modulation perturbed the mRNA levels of ECS enzymes and OR regulation genes. Our findings support the role of the ECS in OR regulation during the foetal life of rats and highlight the need for further studies to elucidate its precise role in OR physiology.

RESUMO

A recent study of 17 men with decapitated spermatozoa found that 8 carried two rare SUN5 alleles, and concluded that loss of SUN5 function causes the acephalic spermatozoa syndrome. Consistent with this, the SUN5 protein localises to the head-tail junction in normal spermatozoa, and SUN proteins are known to form links between the cytoskeleton and the nucleus. However, six of the ten SUN5 variants reported were missense with an unknown effect on function, and only one man carried two high confidence loss-of-function (LOF) alleles: p.Ser284* homozygozity. One potential exonic splice mutation, homozygous variant p.Gly114Arg, was not tested experimentally. Thus, definitive proof that loss of SUN5 function causes the acephalic spermatozoa syndrome is still lacking. Based on these findings, we determined the sequence of the SUN5 gene in three related men of North African origin with decapitated spermatozoa. We found all three men to be homozygous for a deletion-insertion variant (GRCh38 - chr20:32995761_32990672delinsTGGT) that removes 5090 base pairs including exon 8 of SUN5, predicting the frameshift, p.(Leu143Serfs*30), and the inactivation of SUN5. We therefore present the second case where the acephalic spermatozoa syndrome is associated with two LOF alleles of SUN5. We also show that the p.Gly114Arg variant has a strong inhibitory effect on splicing in HeLa cells, evidence that homozygozity for p.Gly114Arg causes acephalic spermatozoa syndrome through loss of SUN5 function. Our results, together with those of the previous study, show that SUN5 is required for the formation of the sperm head-tail junction and male fertility.

RESUMO

OBJECTIVE: Turner syndrome (TS) is responsible for gonadal dysgenesis with high risk of premature ovarian insufficiency. Little is known about fertility preservation (FP) strategies is this population. DESIGN: Data from women with TS consulting with a fertility specialist in our FP centre from 2014 to 2018 were retrospectively collected. MEASUREMENT: Total number of mature oocytes cryopreserved using vitrification. PATIENTS: Nine women with TS were referred. Three women with different karyotypes underwent controlled ovarian stimulation (COS) for oocyte vitrification. Mean age at TS diagnosis was 13.7 years [9-20]. Mean referral delay between TS diagnosis and fertility consultation was 9.7 years [7-14]. First counselling for FP was provided at 23.7 years [18-28]. Mean AMH serum level prior to COS was 53.8 pmol/L [3.6-95]. RESULTS: All three women succeeded in obtaining cryopreserved oocytes with a mean number of 15.3 per woman [9-20] and 9.2 per COS cycle [2-20]. Ovarian response to COS was unexpectedly remarkable for the woman with a complete 45,X monosomy. Procedure was well tolerated for all women. None of them have used oocytes for in vitro fertilization yet. CONCLUSIONS: Independently of karyotype, antral follicular count, AMH and FSH levels seemed to be reliable predictive markers of oocyte cryopreservation success. In a monosomic TS woman, cryptic ovarian mosaicism could explain a successful ovarian response to stimulation with a high number of retrieved oocytes. In case of spontaneous menarche, TS adolescents should be referred during transition to adulthood for FP counselling to avoid referral delay and limit time-related diminished ovarian reserve.

RESUMO

Despite rectal cancer being unusual before 40, fertility preservation (FP) remains a major concern for these reproductive-age women. Treatment usually involves pelvic radiotherapy, neoadjuvant chemotherapy, and surgery of rectum and mesorectum resection, at high risk of impairing fertility in women with risks of premature ovarian failure and radio-induced uterus damage. To date, there is no consensus on FP strategy for rectal cancer. We shared experiences between oncofertility experts from a French research network Groupe de Recherche et d'Etude en Cryoconservation Ovarienne et Testiculaire about a case of rectal cancer in a young woman. Indications, advantages and disadvantages of different FP strategies were discussed: ovarian transposition, cryopreservation of ovarian cortex and oocyte vitrification. This case was the starting point that led to the development of a French multidisciplinary e-meeting for sharing experiences and for suggesting the best strategy when faced with a complex oncofertility case.

RESUMO

INTRODUCTION: Although bariatric surgery seems to increase spontaneous fertility by improving ovulatory function in young women, its impact on ovarian reserve remains largely unknown. OBJECTIVE: To evaluate changes in serum anti-Mullerian hormone (AMH) levels in reproductive-age severely obese women after bariatric surgery (BS). METHODS: AMH levels were measured retrospectively in 39 women (mean age 34.6 ± 1.1 years, range 18-45) that underwent a sleeve gastrectomy or Roux-en-Y gastric bypass (RYGB) at baseline, and 6 and 12 months after BS. Metabolic and micronutrient status, including fasting plasma insulin and glucose, HOMA-IR, leptin, adiponectin, calcium, albumin, transthyretin, ferritin, vitamins (B9, B12, B1, A, E, D), zinc, and selenium, were assessed in all patients before and 1 year after BS. RESULTS: Of the patients, 79% had class-3 obesity. At 6 and 12 months, mean total weight losses (TWL) were 26 and 30%; mean excess weight losses (EWL) were 61.7 and 70.2%. Compared to baseline, AMH levels significantly decreased by 18% at 6 months, and 32% at 12 months post-operatively (p = 0.010 and p = 0.001, respectively). There was no correlation between AMH variation and changes in metabolic parameters or micronutrient levels. Remarkably, changes in AMH levels did not differ between sleeve and RYGB patients and were not correlated with EWL. CONCLUSION: This pilot study shows a drastic reduction in AMH levels at 1 year after BS in reproductive-age severely obese women, which was not related to weight loss: this suggests a negative impact of BS on ovarian reserve, at least in the short term.

RESUMO

The aim of this study was to characterize the nuclear lamina (NL) and lamin chromatin-partners in spermatozoa from four DPY19L2-deleted globozoospermic patients. We tested for spermatid transcripts encoding lamins and their chromatin-partners emerin, LAP2α, BAF and BAF-L, by reverse transcriptase-PCR using spermatozoa RNA. We also determined the localization of lamin B1, BAF and BAF-L by immunofluorescent analysis of spermatozoa from all patients. In RNA from globozoospermic and control spermatozoa we detected transcripts encoding lamin B1, lamin B3, emerin, LAP2α and BAF-L, but not A-type lamins. In contrast, BAF transcripts were detected in globozoospermic but not control spermatozoa. The NL was immature in human globozoospermic spermatozoa: lamin B1 signal was detected in the nuclei of globozoospermic spermatozoa in significantly higher proportions than the control (P < 0.05; 56-91% versus 40%) and was predominantly observed at the whole nuclear periphery, not polarized as in control spermatozoa. Conversely, BAF and BAF-L were detected in control, but not globozoospermic spermatozoa. Our results strongly emphasize the importance of the NL and associated proteins during human spermiogenesis. In globozoospermia, the lack of maturation of the NL, and the modifications in expression and location of chromatin-partners, could explain the chromatin defects observed in this rare phenotype.

PURPOSE: To assess the factors associated with a poor prognosis for a cumulative IVF live birth rate (LBR) in women with stage III and IV endometriosis according to the revised classification of the American Fertility Society (rAFS). METHODS: A retrospective cohort study was conducted between January 1, 2010, and December 31, 2014, in our Reproductive Medicine Center. We analyzed different factors associated with a poor prognosis for a cumulative IVF LBR in women with rAFS stage III and IV endometriosis. A total of 101 patients were included, representing 232 IVF-ICSI cycles and 212 embryo transfers. The primary endpoint was the cumulative LBR per cycle and per patient. RESULTS: The cumulative LBR per cycle was 14.7% (n = 34) and that per patient was 31.7% (n = 32). The cumulative LBR was significantly decreased by active smoking [adjOR = 3.4, 95% CI (1.12-10.60), p = 0.031], poor ovarian response (POR) according to the Bologna criteria [adjOR = 11.5, 95% CI (1.37-96.83), p = 0.024], and rAFS stage IV [adjOR = 3.2, 95% CI (1.13-8.95), p = 0.024]. The cumulative LBR per women was 59.4% without factors associated with a poor prognosis and 25.6% in the case of one factor, and it decreased to 7.7% in the case of two or three factors (p < 0.001). CONCLUSION: Active smoking, POR according to the Bologna criteria, and rAFS stage IV endometriosis had a negative impact on the IVF-ICSI cumulative LBR for women with rAFS stage III and IV endometriosis. Because smoking dramatically decreases the LBR with endometriosis, stopping smoking before IVF-ICSI should be strongly advised.

RESUMO

PURPOSE: Does the type of anesthesia (paracervical block (PCB) or general anesthesia (GA)) impact live birth rate, pain, and patient satisfaction? METHODS: A non-randomized prospective cohort study was conducted in women treated for IVF. Two groups of patients were prospectively included: the PCB group (n = 234) and the GA group (n = 247). The type of anesthesia was determined by the patients. The primary endpoint was cumulative live birth rate by OR. Secondary endpoints were self-assessment of the patients' peri-operative abdominal and vaginal pain vs the doctors' evaluations during PCB, post-operative abdominal and vaginal pain level, and patient satisfaction in both groups. Pain levels were assessed with a numerical rating scale (NRS). RESULTS: The live birth rate was similar in both groups (19.8% in the GA group vs 20.9% in the PCB group, P = 0.764). During oocyte retrieval in the PCB group, the physicians significantly under-estimated the vaginal pain experienced by the patients (3.04 ± 0.173 for patients vs 2.59 ± 0.113 for surgeons, P = 0.014). Post-operative vaginal and abdominal pain were significantly greater in the PCB group compared to the GA group (2.26 ± 0.159 vs 1.66 ± 0.123, respectively, P = 0.005, and 3.80 ± 0.165 vs 3.00 ± 0.148, respectively, P < 0.001). Patients were more significantly satisfied with GA than with PBC (P < 0.001). CONCLUSION: Because the LBR was similar in both groups and patient satisfaction was high, the choice of anesthesia should be decided by the patients.

RESUMO

Steroidogenic acute regulatory protein (StAR) mutations are the most frequent aetiologies of congenital lipoid adrenal hyperplasia (CLAH). Phenotypes may vary, and puberty may be absent in affected individuals. To date, only two pregnancies have been described in 46,XX CLAH patients with StAR mutations; these patients exhibited ovarian steroidogenesis along with spontaneous puberty and menarche and normal menses. The patient described here presented with CLAH caused by the homozygous (unreported, 1 bp) deletion c.719del in the StAR gene, which was diagnosed after acute adrenal insufficiency when the patient was 10 days old. The patient did not undergo spontaneous puberty, so puberty was induced by HRT when the patient was 13 years old. At the age of 25 years, the patient was referred to our reproductive unit because she desired to conceive. An initial cycle of clomiphene, stimulation produced follicular growth with two mature follicles measuring 18 and 15 mm, respectively, but the plasma oestradiol levels remained low (18 pg/ml) and the endometrium was thin (3 mm). Pregnancy was finally achieved after ovarian stimulation, IVF and transfer of frozen-thawed embryos after endometrial preparation with HRT. A normal female child was delivered following a 40 weeks' uneventful pregnancy. We therefore report the first IVF pregnancy achieved in a 46,XX CLAH patient homozygous for a StAR mutation, with inadequate ovarian steroidogenesis and no spontaneous puberty.

RESUMO

INTRODUCTION: A discussion about sexuality should become a routine part of the personalized care pathway for patients with cancer. AIM: To assess rates of patient discussion about sexuality with health care providers after cancer. METHODS: We used data from the representative French nationwide 2012 VICAN survey, which included 4,349 adults 18 to 82 years old who were still alive 2 years after diagnosis at 12 cancer sites. MAIN OUTCOME MEASURES: Self-reported rates of discussion about sexuality with health care providers were assessed, and associated factors were tested after systematic adjustment for a sexual health indicator (created from six items of the Relationship and Sexuality Scale). RESULTS: Of 4,181 respondents to the question on a discussion about sexuality, 54.7% reported that nobody had proposed a discussion to them, 21.9% did not want any discussion, and 23.4% had had a discussion. Women had less discussion about sexuality with health care providers (11.1% vs 36.7% of men, P < .001) and were more likely to request a discussion at their own initiative (62.9% vs 48.0% of men, P < .001). Discussion about sexuality was more frequent with patients with prostate (56.3%) and cervical (39.6%) cancer, but increasing age was associated with a greater reluctance to discuss this issue (odds ratio = 1.17, 95% CI = 1.04-1.2). The likelihood of discussion increased with severe sexual problems, radiotherapy, general sequelae, having an information-seeker profile, previous professional psychological help, and initial treatment in private centers. Patients initially wishing for psychological help were more likely to desire a discussion about sexuality. CONCLUSION: Sexuality receives little attention in French patients with cancer. Inequalities in the discussion about sexuality were observed in relation to the type of care center where the patient was initially managed. Information on supportive interventions, including more systematic referral for professional psychological help, should be developed to facilitate discussion and should be offered to all patients, irrespective of severity of sexual problems, age, sex, cancer site, and care center.

RESUMO

PURPOSE: The aim of this study is to assess the feasibility of ovariectomy by single-port access laparoscopy for cryopreservation. METHODS: Observational prospective monocentric study including patients referred for an ovariectomy for ovarian tissue cryopreservation underwent ovariectomy by single-port access laparoscopy. Feasibility, intra- and post-operative complications, and quality of the ovarian tissue collected were reported. RESULTS: Height patients were included. No conversion to standard laparoscopy or laparotomy was performed and no intra- or post-operative complications were reported. Median duration of surgery was 35 min (30-60). The quality of all the ovarian tissue collected was correct, and cryopreservation was possible for all patients. CONCLUSIONS: Ovariectomy for cryopreservation by laparoscopy with SPA seems feasible. The advantages of this technique are particularly interesting in these patients who require the least aggressive surgical technique possible and a rapid convalescence.
