RESUMO

The Phylum Cressdnaviricota consists of a large number of circular Rep-encoding single-stranded (CRESS)-DNA viruses. Recently, metagenomic analyzes revealed their ubiquitous distribution in a diverse range of eukaryotes. Data relating to CRESS-DNA viruses in humans remains scarce. Our study investigated the presence and genetic diversity of CRESS-DNA viruses in human vaginal secretions. Vaginal swabs were collected from 28 women between 29 and 43 years old attending a fertility clinic in New York City. An exploratory metagenomic analysis was performed and detection of CRESS-DNA viruses was confirmed through analysis of near full-length sequences of the viral isolates. A phylogenetic tree was based on the REP open reading frame sequences of the CRESS-DNA virus genome. Eleven nearly complete CRESS-DNA viral genomes were identified in 16 (57.1%) women. There were no associations between the presence of these viruses and any demographic or clinical parameters. Phylogenetic analysis indicated that one of the sequences belonged to the genus Gemycircularvirus within the Genomoviridae family, while ten sequences represented previously unclassified species of CRESS-DNA viruses. Novel species of CRESS-DNA viruses are present in the vaginal tract of adult women. Although they be transient commensal agents, the potential clinical implications for their presence at this site cannot be dismissed.

RESUMO

Importance: Poor ovarian response (POR) to stimulation may impact patients' desire or need to utilize cryopreserved oocytes for family building in the future. These findings, captured by Society for Assisted Reproductive Technology (SART) national data, underscore the need for tailored counseling and further research into the decision-making processes influencing oocyte utilization. Objective: To examine the association of ovarian response to stimulation and the number of vitrified oocytes with the likelihood and timing of patients returning for oocyte utilization following planned oocyte cryopreservation (OC). Design, Setting, and Participants: This cohort study used data in the SART Clinical Outcome Reporting System for patients in US fertility clinics and data was used for eligible patients who underwent planned OC from January 2014 through December 2020. Data were analyzed from November 2022 to June 2023. Main outcomes and measures: The association between number of oocytes cryopreserved on return rate to utilize cryopreserved oocytes and the time from vitrification to warming. Results: A total of 67 893 autologous oocyte freezing cycles were performed in the US between 2014 and 2020, among 47 363 patients (mean [SD] age, 34.5 [4.7] years). Of these, 6421 (13.5%) were classified as patients with POR, with fewer than 5 oocytes vitrified across all ovarian stimulation cycles. A total of 1203 patients (2.5%) returned for oocyte warming and utilization. The rate of return was significantly higher in the POR group, with 260 (4.0%) returning compared with 943 (2.3%) in the normal responder group (P < .001). This trend was most notable in the age 30 to 34 years (warm cycle, 46 of 275 [16.7%] vs no warm cycle, 982 of 11 743 [8.4%]; P < .001) and age 35 to 39 years groups (warm cycle, 124 of 587 [21.1%] vs no warm cycle, 3433 of 23 012 [14.9%]; P < .001). The time elapsed from vitrification to warming was comparable between patients with POR (mean [SD], 716.1 [156.1] days) and normal responders (803.8 [160.7] days). A multivariate analysis adjusted for age, clinic region in the US, body mass index, and history of endometriosis was conducted to identify factors associated with the utilization of oocytes. The analysis revealed that having fewer than 5 oocytes vitrified was associated with higher odds of utilizing oocytes (OR, 1.52; 95% CI, 1.32-1.76). Conclusions and Relevance: This cohort study reveals a distinct pattern in the utilization of cryopreserved oocytes among patients undergoing planned OC in the US. Despite the increase in number of patients pursuing OC, there is a notably low rate of return to utilize previously vitrified oocytes; notably, patients with POR are more likely to return, although the time to return is similar to those with normal ovarian response.

RESUMO

OBJECTIVE: To describe the laparoscopic management of an obstructed uterus didelphys before and after treatment for pelvic inflammatory disease. To compare the appearance of pelvic organs during active infection with their appearance after washout and appropriate antibiotic treatment, emphasizing the importance of knowing when to abort a procedure. DESIGN: Video demonstration of surgical and medical management considerations during a complex pelvic surgery. Visualization of tissue healing that occurs with appropriate antibiotic treatment. SETTING: Academic Center. PATIENT: A patient who presents for definitive surgical management of a uterus didelphys with an obstruction at her right hemicervix. Her presentation is complicated by a tubo-ovarian abscess. INTERVENTION: A uterus didelphys is classically defined as two hemiuteri with duplicated cervices with or without a longitudinal vaginal septum. Uterus didelphys may have an obstruction and/or communication between the two uterine horns, in which case patients may present with complications such as cyclic pelvic pain from hematometra or genital tract infection. This is a case report of a 14-year-old G0 who presented to the emergency department with two weeks of vaginal bleeding, severe diffuse abdominal pain, and malodorous vaginal discharge. Transabdominal ultrasound and a magnetic resonance imaging of the pelvis established a new diagnosis of a uterus didelphys with an obstruction at her right hemicervix and a fistulous tract connecting her right and left hemiuteri at the level of the internal cervical os. She was also found to have a 3 cm left ovarian cyst and a new finding of congenital absence of her right kidney. Patient was administered ceftriaxone, doxycycline, and metronidazole antibiotics as treatment of presumed pelvic inflammatory disease but experienced minimal improvement after 24 hours. The decision was made to proceed with surgical intervention. A survey of the pelvis revealed significant inflammation, friable peritoneum, and endometriosis. The uterine horns in didelphic configurations were visualized. The fimbriae at the left fallopian tube were notably splayed out, swollen, and inflamed. There was a notable large mass in the location where the ovarian cyst had been previously described on imaging. A large amount of purulent material was expressed when compressed, consistent with a tubo-ovarian abscess. The infection likely originated from the menstrual blood collection at the right obstructed cervix that ascended through the communication between the right and left hemiuteri. The pelvis was irrigated thoroughly. At this point, the decision was made to stop the procedure, pursue antibiotic treatment, and resolve the active infection before correcting her complex müllerian anomaly. Patient continued on her antibiotic course, which included piperacillin-tazobactam, while hospitalized, followed by a five-day course of amoxicillin-clavulanate. She was also placed on medroxyprogesterone acetate for menstrual suppression. MAIN OUTCOME MEASURE: Advantage of allowing time for antibiotic treatment and tissue healing before repair of a complex müllerian anomaly. RESULT: With antibiotic treatment, she recovered well postoperatively with resolution of her pain. Three months later, she returned to the operating room for definitive surgical management of her obstructed uterine didelphys. On laparoscopy, there was a significant improvement in tissue quality. Most notably, the fimbriae of the left fallopian tube were no longer inflamed. We proceeded with the planned correction of the complex müllerian anomaly. After resection of the right uterine horn, the fistula tract was identified and also resected. The defect in the right hemicervix was closed over, reinforcing the medial side of the left hemicervix. She had an uncomplicated postoperative recovery, and menses resumed without pain. CONCLUSIONS: The presented case provides unique insight into the tissue healing that occurs before and after antibiotic treatment. Knowing when to stop, especially in the setting of an active infection, is extremely important for performing a procedure safely, minimizing harm, and allowing for robust tissue repair. It is also important to optimize modifiable preoperative factors before correcting a complex müllerian anomaly. Assessing and reassessing the situation during a complex pelvic surgery is essential, especially in the setting of a complex müllerian anomaly where the preoperative examination and imaging may not be definitive.

RESUMO

Müllerian anomalies represent a complex collection of developmental defects occurring in up to 5% of the general population. They are increasingly more common in individuals with infertility (8.0%) and in those with a history of pregnancy loss (13.3%); they have the highest prevalence in individuals with a history of both (24.5%). A wide spectrum of anomalies can occur based on the stage at which müllerian development ceases in utero, ranging from mild (eg, a partial uterine septum) to severe, with complete absence of the cervix, uterus, and fallopian tubes (eg, müllerian agenesis). The components of the reproductive tract involved and, importantly, whether an obstruction of the tract is involved correlates with the timing of presentation, the constellation of associated symptoms, and the necessity for either medical or surgical management. Individuals, regardless of the severity of the defect, should be counseled on the gynecologic, reproductive, and obstetric risks associated with their specific müllerian anomaly to minimize adverse sequela and outcomes. We will review the clinical presentation, diagnostic evaluation, and clinical counseling of individuals with müllerian anomalies.

RESUMO

PROBLEM: The association of viruses with infertility remains incompletely evaluated. METHOD OF STUDY: Vaginal secretions from 46 women seeking treatment in the Center for Reproductive Medicine and Infertility at Weill Cornell Medicine were tested for viruses by metagenomic analysis by lab personnel blinded to all clinical data. RESULTS: Torquetenovirus (TTV) was identified in 16 women, alphapapillomavirus in seven women and most were positive for bacteriophages. Twelve of the subjects were fertile and sought to freeze their oocytes for future implantation. These women were all negative for TTV. In contrast, 16 of the 34 women (47.1%) being treated for infertility were TTV-positive (p = .0035). Evaluating the women by cause of infertility, five of nine women (55.6%) whose male partner had inadequate sperm parameters and six of 14 women (42.9%) with defective ovulation were TTV positive (p = .0062 and p = .0171, respectively, vs. the fertile women). Alphapapillomavirus was identified in one (8.3%) fertile woman, five (35.7%) women with ovulation deficiency, and one (11.1%) woman with male factor infertility. These differences were not statistically significant. There were no differences in bacteriophage families or the presence of Lactobacillus phages between fertile or infertile women or between different causes of infertility. There was a negative association between TTV detection and Lactobacillus crispatus dominance in the vaginal microbiota (p = .0184), but no association between TTV detection and the presence of alphapapillomavirus or Candida species. CONCLUSION: Detection of TTV in the vagina might be a biomarker for specific causes of infertility.

RESUMO

Think about 6 loved ones of reproductive age in your life. Now imagine that 1 of these 6 individuals is suffering from infertility. Perhaps they feel alone and isolated, unable to discuss their heartbreak with their closest friends, family, and support network. Suffering in silence. In this editorial, we discuss the infertility journey through the lens of the patients, the providers, and the scientists who struggle with infertility each and every day. Our goal is to open a dialogue surrounding infertility, with an emphasis on dismantling the longstanding societal barriers to acknowledging male infertility as a disease. Through education, communication, compassion, and advocacy, together we can all begin to break the deafening silence of male infertility.

RESUMO

BACKGROUND: Approximately 15% of all clinically recognized pregnancies in patients with infertility result in spontaneous abortion. However, despite its potential to have a profound and lasting effect on physical and emotional well-being, the natural history of spontaneous abortion in women with infertility has not been described. Although vaginal bleeding is a common symptom in pregnancies conceived via reproductive technologies, its prognostic value is not well understood. OBJECTIVE: This study aimed to evaluate the combination of early pregnancy bleeding and first-trimester ultrasound measurements to determine spontaneous abortion risk. STUDY DESIGN: This was a retrospective cohort study of patients with infertility who underwent autologous embryo transfer resulting in singleton intrauterine pregnancy confirmed by ultrasound from January 1, 2017, to December 31, 2019. Early pregnancy symptoms of bleeding occurring before gestational week 8 and measurements of crown-rump length and fetal heart rate from ultrasounds performed during gestational week 6 (6 0/7 to 6 6/7 weeks of gestation) and gestational week 7 (7 0/7 to 7 6/7 weeks of gestation) were recorded. Modified Poisson regression with robust error variance was adjusted a priori for patient age, embryo transfer day, and transfer of a preimplantation genetic-tested embryo to estimate the relative risk and 95% confidence interval of spontaneous abortion for dichotomous variables. The relative risks and positive predictive values for early pregnancy bleeding combined with ultrasound measurements on the occurrence of spontaneous abortion were calculated for patients who had an ultrasound performed during gestational week 6 and separately for patients who had an ultrasound performed during gestational week 7. The primary outcome was spontaneous abortion in the setting of vaginal bleeding with normal ultrasound parameters. The secondary outcomes were spontaneous abortion with vaginal bleeding and (1) abnormal crown-rump length, (2) abnormal fetal heart rate, and (3) both abnormal crown-rump length and abnormal fetal heart rate. RESULTS: Of the 1858 patients who were included (359 cases resulted in abortions and 1499 resulted in live births), 315 patients (17.0%) reported vaginal bleeding. When combined with ultrasound measurements from gestational week 6, bleeding was significantly associated with increased spontaneous abortion only when accompanied by absent fetal heart rate (relative risk, 5.36; 95% confidence interval, 3.36-8.55) or both absent fetal heart rate and absent fetal pole (relative risk, 9.67; 95% confidence interval, 7.45-12.56). Similarly, when combined with ultrasound measurements from gestational week 7, bleeding was significantly associated with increased spontaneous abortion only when accompanied by an abnormal assessment of fetal heart rate or crown-rump length (relative risk, 5.09; 95% confidence interval, 1.83-14.19) or both fetal heart rate and crown-rump length (relative risk, 14.82; 95% confidence interval, 10.54-20.83). With normal ultrasound measurements, bleeding was not associated with increased spontaneous abortion risk (relative risk: 1.05 [95% confidence interval, 0.61-1.78] in gestational week 6 and 0.80 [95% confidence interval, 0.36-1.74] in gestational week 7), and the live birth rate was comparable with that in patients with normal ultrasound measurements and no bleeding. CONCLUSION: Patients with a history of infertility who present after embryo transfer with symptoms of vaginal bleeding should be evaluated with a pregnancy ultrasound to accurately assess spontaneous abortion risk. In the setting of normal ultrasound measurements, patients can be reassured that their risk of spontaneous abortion is not increased and that their live birth rate is not decreased.

RESUMO

BACKGROUND: Few studies have directly compared different surgical procedures for uterine fibroids with respect to long-term health-related quality of life outcomes and symptom improvement. OBJECTIVE: We examined differences in change from baseline to 1-, 2-, and 3-year follow-up in health-related quality of life and symptom severity among patients who underwent abdominal myomectomy, laparoscopic or robotic myomectomy, abdominal hysterectomy, laparoscopic or robotic hysterectomy, or uterine artery embolization. STUDY DESIGN: The COMPARE-UF registry is a multiinstitutional prospective observational cohort study of women undergoing treatment for uterine fibroids. A subset of 1384 women aged 31 to 45 years who underwent either abdominal myomectomy (n=237), laparoscopic myomectomy (n=272), abdominal hysterectomy (n=177), laparoscopic hysterectomy (n=522), or uterine artery embolization (n=176) were included in this analysis. We obtained demographics, fibroid history, and symptoms by questionnaires at enrollment and at 1, 2, and 3 years posttreatment. We used the UFS-QoL (Uterine Fibroid Symptom and Quality of Life) questionnaire to ascertain symptom severity and health-related quality of life scores among participants. To account for potential baseline differences across treatment groups, a propensity score model was used to derive overlap weights and compare total health-related quality of life and symptom severity scores after enrollment with a repeated measures model. For this health-related quality of life tool, a specific minimal clinically important difference has not been determined, but on the basis of previous research, a difference of 10 points was considered as a reasonable estimate. Use of this difference was agreed upon by the Steering Committee at the time when the analysis was planned. RESULTS: At baseline, women undergoing hysterectomy and uterine artery embolization reported the lowest health-related quality of life scores and highest symptom severity scores compared with those undergoing abdominal myomectomy or laparoscopic myomectomy (P<.001). Those undergoing hysterectomy and uterine artery embolization reported the longest duration of fibroid symptoms with a mean of 6.3 years (standard deviation, 6.7; P<.001). The most common fibroid symptoms were menorrhagia (75.3%), bulk symptoms (74.2%), and bloating (73.2%). More than half (54.9%) of participants reported anemia, and 9.4% women reported a history of blood transfusion. Across all modalities, total health-related quality of life and symptom severity score markedly improved from baseline to 1-year with the largest improvement in the laparoscopic hysterectomy group (Uterine Fibroids Symptom and Quality of Life: delta= [+] 49.2; symptom severity: delta= [-] 51.3). Those undergoing abdominal myomectomy, laparoscopic myomectomy, and uterine artery embolization also demonstrated significant improvement in health-related quality of life (delta= [+]43.9, [+]32.9, [+]40.7, respectively) and symptom severity (delta= [-]41.4, [-] 31.5, [-] 38.5, respectively) at 1 year, and the improvement persisted from baseline for uterine-sparing procedures during second (Uterine Fibroids Symptom and Quality of Life: delta= [+]40.7, [+]37.4, [+]39.3 SS: delta= [-] 38.5, [-] 32.0, [-] 37.7 and third year (Uterine Fibroids Symptom and Quality of Life: delta= [+] 40.9, [+]39.9, [+]41.1 and SS: delta= [-] 33.9, [-]36.5, [-] 33.0, respectively), posttreatment intervals, however with a trend toward decline in degree of improvement from years 1 and 2. Differences from baseline were greatest for hysterectomy; however, this may reflect the relative importance of bleeding in the Uterine Fibroids Symptom and Quality of Life, rather than clinically meaningful symptom recurrence among women undergoing uterus-sparing treatments. CONCLUSION: All treatment modalities were associated with significant improvements in health-related quality of life and symptom severity reduction 1-year posttreatment. However, abdominal myomectomy, laparoscopic myomectomy and uterine artery embolization indicated a gradual decline in symptom improvement and health-related quality of life by third year after the procedure.

RESUMO

For years, reproductive surgery was the mainstay of reproductive care. With the evolution and ultimate success of in vitro fertilization (IVF), reproductive surgery became an adjuvant therapy, indicated mainly for severe symptoms or to enhance success rates with assisted reproductive technologies. As success rates for IVF have plateaued, and emerging data rekindles the enormous benefits of surgically correcting reproductive pathologies, there is renewed interest among reproductive surgeons in reviving research and surgical expertise in this area. In addition, new instrumentation and surgical techniques to preserve fertility have gained traction and will solidify the need to have skilled reproductive endocrinology and infertility surgeons in our practice.

RESUMO

Objective: To compare 12-month post-treatment health-related quality of life (HR-QoL) and symptom severity (SS) changes among patients with symptomatic uterine fibroids (SUF) not seeking fertility and undergo a hysterectomy, abdominal myomectomy (AM), or uterine artery embolization (UAE). Materials and Methods: The Comparing Options for Management: Patient-Centered Results for Uterine Fibroids (COMPARE-UF) Registry is a multi-institutional prospective observational cohort study of patients treated for SUF. A subset of 1465 women 31-45 years of age, who underwent either hysterectomy (n = 741), AM (n = 446), or UAE (n = 155) were included in this analysis. Demographics, fibroid history, and symptoms were obtained by baseline questionnaires and at 1 year post-treatment. Results were stratified by all treatments and propensity score weighting to adjust for differences in baseline characteristics. Results: Women undergoing UAE reported the lowest baseline HR-QoL and highest SS scores (mean = 40.6 [standard deviation (SD) = 23.8]; 62.3 [SD = 24.2]) followed by hysterectomy (44.3 [24.3]; 59.8 [SD = 24.1]). At 12 months, women who underwent a hysterectomy experienced the largest change in both HR-QoL (48.7 [26.2]) and SS (51.9 [25.6]) followed by other uterine-sparing treatments. Propensity score weighting revealed all treatments produced substantial improvement, with hysterectomy patients reporting the highest HR-QoL score (92.0 [17.8]) compared with myomectomy (86.7 [17.2]) and UAE (82.6 [21.5]) (p < 0.0001). Similarly, hysterectomy patients reported the lowest SS scores (8.2 [15.1]) compared with myomectomy (16.5 [15.1]) and UAE (19.6 [17.5]) (p < 0.0001). Conclusion: All procedures showed improvement in HR-QoL and reduction in SS score at 12 months, hysterectomy showing maximum improvement. Of importance, at 12 months, patients who underwent either a myomectomy or UAE reported comparable symptom relief and HR-QoL. Clinicaltrials.Gov Identifier: NCT02260752.

RESUMO

With the rise of efficient and highly effective embryo cryopreservation techniques, the modern in vitro fertilization laboratory has unintentionally become a long-term storage facility for embryos and gametes. One challenge posed by long-term storage is the issue of unclaimed, effectively abandoned, cryopreserved embryos whose owners cannot be identified or are unable to provide a dispositional decision. Given the nuanced nature of dealing with human tissue, no straightforward solutions for managing this novel scenario have prevailed. In this article, we discuss the problem faced by physicians, clinics, and patients alike when faced with unclaimed cryopreserved embryos. We also review strategies for proactive prevention and resolution of conflicts that may arise when making dispositional decisions.

RESUMO

OBJECTIVE: To assess the association between antimüllerian hormone (AMH) and embryo ploidy rates in 2 cohorts of patients undergoing in vitro fertilization (IVF) with trophectoderm biopsy for preimplantation genetic testing for aneuploidy (PGT-A): the general population of women pursuing IVF with PGT-A (Infertile cohort) and women pursuing IVF with preimplantation genetic testing for monogenic disorders (PGT-M) owing to the risk of hereditary monogenic diseases (Non-infertile cohort). DESIGN: Retrospective cohort study. SETTING: Academic center. PATIENT(S): Patients undergoing their first cycle of IVF with trophectoderm biopsy and PGT-A or PGT-A and PGT-M in our center between March 2012 and June 2020. Patients of advanced maternal age according to the Bologna criteria (age ≥40 years) and patients who underwent fresh embryo transfers were excluded. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Proportion of euploid, mosaic, and aneuploid embryos per cycle. RESULT(S): "Infertile" (n = 926) and "Non-infertile" (n = 214) patients were stratified on the basis of AMH levels, with low-AMH defined as <1.1 ng/mL in accordance with the Bologna criteria. Age-adjusted regression models showed no relationship between AMH classification and proportion of euploid, mosaic, and aneuploid embryos in the Infertile or Non-infertile cohorts. In the Infertile cohort, no association between AMH classification and embryo ploidy rates was identified in a subgroup analysis of patients aged <35 years, 35-37 years, and 38-39 years. These findings persisted in a sensitivity analysis of infertile patients stratified into AMH (ng/mL) quartile categories. CONCLUSION(S): No association was found between AMH and the proportion of euploid, mosaic, or aneuploid embryos in 2 large cohorts of patients undergoing IVF with PGT-A (Infertile patients) or PGT-A and PGT-M (Non-infertile patients), suggesting that a quantitative depletion of ovarian reserve does not predict the ploidy status of the embryo cohort.

RESUMO

OBJECTIVE: To determine the ongoing pregnancy rate among patients with infertility with a low antimüllerian (AMH) level compared with those with a normal AMH level after oral and injectable ovulation induction (OI)/intrauterine insemination (IUI). DESIGN: Retrospective cohort. SETTING: Academic center. PATIENT(S): Patients completing ≥1 medicated OI/IUI cycle at our center between 2015 and 2019 were included. The AMH levels were measured within 12 months of treatment initiation. The cohort was stratified into low AMH (AMH level, <1.0 ng/mL) and normal AMH (AMH level, ≥1.0 ng/mL) groups. All subsequent medicated OI/IUI cycles occurring within 1 year of initial cycle start date were included up to the third completed cycle or until an ongoing pregnancy was recorded. Patients were stratified by age (<35, 35-40, and >40 years), and the relationship between the low and normal AMH groups and each binary endpoint were quantified as risk ratios using the age-adjusted Poisson models. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Ongoing pregnancy. RESULT(S): A total of 3,122 patients completed 5,539 oral antiestrogen cycles, and 1,060 completed 1,630 injectable gonadotropin cycles. For oral antiestrogen treatment, pregnancy outcomes, including ongoing pregnancy rate per cycle, for patients with a low AMH level were comparable with those for patients with a normal AMH level (<35 years, 15.4% vs. 14.9%; 35-40 years, 10.0% vs. 11.0%; and >40 years, 2.8% vs. 3.3%). For injectable gonadotropin treatment, the ongoing pregnancy rate was lower in the low AMH group than in the normal AMH group for the ages of <35 (12.1% vs. 23.5%; relative risk [RR], 0.52 [95% confidence interval {CI}, 0.28-0.97]) and 35-40 (12.5% vs. 18.5%; RR, 0.70 [95% CI, 0.49-0.99]) years but comparable with that for patients aged >40 years (3.0% vs. 4.0%; RR, 0.86 [95% CI, 0.31-2.35]). The proportion of multifetal gestations was similar between the low and normal AMH groups treated with oral antiestrogens (13.1% vs. 10.8%); however, for injectable gonadotropin treatment, patients with a normal AMH level had a higher proportion of multifetal gestations (18.6% vs. 31.1%). CONCLUSION(S): Compared with normal ovarian reserve, treatment with oral antiestrogens for OI/IUI for patients with low ovarian reserve results in comparable follicular development and ongoing pregnancy rates for all age groups. When patients with low ovarian reserve are treated with gonadotropins for OI/IUI, multifollicular recruitment is less likely resulting in a significantly decreased ongoing pregnancy rate for patients aged <35 and 35-40 years but also a decrease in multifetal gestations. Overall, the ongoing pregnancy rates of 8.7% per oral antiestrogen cycle and 8.1% per injectable gonadotropin cycle in patients with low ovarian reserve are comparable with the expected rates in the general infertility population.

RESUMO

OBJECTIVE: To estimate the live-birth rate per in vitro fertilization (IVF) cycle and after cumulative infertility treatment among patients with anti-müllerian hormone (AMH) levels of 0.3 ng/mL or lower. METHODS: We conducted a retrospective cohort study at a single academic center of patients with infertility and AMH levels of 0.3 ng/mL or lower who initiated one or more IVF cycles (2013-2019). Exclusion criteria included prior chemotherapy, hormonal contraceptive use within 3 months of AMH level measurement, and severe male factor infertility. Patients were stratified by Society for Assisted Reproductive Technology (SART) age group. The primary outcome was live-birth rate per IVF cycle. Live-birth outcomes were compared with the 2018 SART National Summary Report for live births per single intended oocyte retrieval, with proportion difference (PD) and 95% CI reported. RESULTS: A total of 978 patients were included. The median (interquartile range) number of cycles initiated was 2 (1-3). With the first initiated cycle, the live-birth rate for those with AMH levels of 0.3 ng/mL or lower was significantly lower in each age category compared with the SART live-birth rate per single initiated cycle (younger than 35 years: 26.2% vs 55.6%, PD 29.4%, 95% CI 20.9-37.9%; 35-37 years: 15.9% vs 40.8%, PD 24.9%, 95% CI 19.0-30.9%; 38-40 years: 12.6% vs 26.8%, PD 14.3%, 95% CI 10.2-18.3%; 41-42 years: 4.7% vs 13.4%, PD 8.7%, 95% CI 5.9-11.6%; older than 42 years: 1.2% vs 4.1%, PD 2.9%, 95% CI 1.5-4.3%). In patients aged 35-37, 38-40, 41-42, and older than 42 years, the cumulative live-birth rate after up to three initiated cycles was comparable with the SART live-birth rate per single initiated cycle but remained significantly lower in patients younger than age 35 years (PD 16.8%, 95% CI 7.3-26.2%). After all treatments were included (cumulative IVF, ovulation induction, and unassisted cycles), live-birth rates were similar to SART live-birth rates per single initiated cycle in all age groups. CONCLUSION: Compared with national outcomes, patients with AMH levels of 0.3 ng/mL or lower had a significantly lower chance of live birth after their first initiated cycle. However, the cumulative live-birth rate after up to three initiated cycles was comparable with national live-birth outcomes per single initiated cycle in patients aged 35 years or older. In patients younger than age 35 years, only when all IVF and non-IVF treatment cycles were included did the cumulative live-birth rate become comparable with the national rate per single IVF cycle.

RESUMO

Objective: To determine the incidence and risk factors for intrauterine adhesions (IUAs) after minimally invasive and open myomectomy and hysteroscopic myomectomy (HM). Design: Retrospective cohort study. Setting: University-affiliated fertility center. Patients: Patients aged ≥18 years undergoing robotic-assisted or conventional laparoscopic minimally invasive myomectomy, abdominal myomectomy, or HM between January 2007 and January 2017. Only patients who underwent uterine cavity evaluation within 12 months of surgery via hysteroscopy or hysterosalpingography were included. Patients were excluded if they had a history of IUA before myomectomy. Interventions: Not applicable. Main Outcome Measures: The primary outcomes of this study were the presence and severity of IUA. The secondary outcomes were the identification of risk factors for IUA formation. The severity of IUAs was scored by 2 investigators using a previously published grading system by March et al. Results: Of 1,315 patients who underwent myomectomy, 173 (13.2%) met the inclusion criteria. Intrauterine adhesions were identified in 9.3% of all patients, 75.0% of which were classified as minimal. The incidence of IUA did not vary by modality: 8.6%, minimally invasive myomectomy; 7.8%, abdominal myomectomy; and 11.8%, HM. There were no differences in incidence of IUA by the number or size of fibroids removed. Of patients with IUA, 87.5% had submucosal fibroids resected compared with 58.6% without IUA. Conclusions: The incidence of postoperative IUA in women undergoing myomectomy of any modality is relatively low (9.3%) and does not vary by modality alone. Most IUAs are of minimal degree. The presence of submucosal fibroids is associated with an increased risk of IUA in all modalities.

RESUMO

Dissociation of embryo transfer from the ovarian stimulation cycle has afforded patients increased flexibility for genetic testing and fertility preservation. Although frozen embryo transfer (FET) has largely been demonstrated to be safe and effective compared with fresh transfer, programmed FET cycles, where a corpus luteum is absent, have come under increasing scrutiny. In observational trials, programmed FET protocols appear to be associated with an increased risk of ineffective decidualization and impaired placental function. Together with the appropriate preexisting risk factors, this additive risk may potentiate hypertensive disorders of pregnancy later in gestation. Efforts to understand the reasons for this apparent risk may afford us opportunities to better individualize the FET cycle type offered to patients with cryopreserved embryos. Randomized controlled trials will help us to understand whether the apparent risk is due to patient factors, which influence protocol choice, or a characteristic of the protocol itself, such as the absence of the corpus luteum or suboptimal replacement of estradiol and progesterone.
