The presence of partial compaction patterns is associated with lower rates of blastocyst formation, sub-optimal morphokinetic parameters and poorer morphologic grade.

BACKGROUND: Compaction is an important marker of embryonic genome activation and marks a critical step in the development to blastocyst. The objective of our study was to determine whether visualization of the embryonic compaction process through time-lapse imaging (TL) can assist in predicting the kinetics of embryo development as well as the likelihood for blastocyst formation, grade, or ploidy. METHODS: This study is a retrospective review of prospectively collected datafrom a single academic institution. Couples included were thosewho underwent preimplantation genetic testing for aneuploidy (PGT-A) following in vitro fertilization between Januaryand December 2020. Embryos were cultured in the Embrysocope. Embryo morphokinetic data was prospectively collected and analyzed.TL videos werelater reviewed in detail for compaction pattern. Embryo compaction patterns (CP) were categorized as follows: 1) full compaction (CP-F), 2) partial compaction with cell extrusion (P-ext), 3) partial compactionwith cell exclusion (P-exc) and 4) partial compactionwith both cell extrusion and exclusion (P-both). Assessment of embryo decompaction and re-compaction was evaluated. The association between CP, morphokinetic parameters,blastocyst formation, grade and ploidy were then analyzed. RESULTS: A total of 349 embryos were studied. Amongst embryos which progressed to morula (n = 281), the distribution of compaction patterns were: CP-F 45.6%, P-ext12.5%, P-exc29.5% and P-both 12.5%. Embryos exhibiting a CP-F were more likely to proceed to blastocyst compared with those that demonstrated partial compaction patterns (p = 0.006). When compared to CP-F, partial compaction patterns were significantly associated with poorer ICM and TE grades (P < 0.001). Of the 281 morula, 59.8% (n = 168) demonstrated at least one episode of decompaction and re-compaction. Of the 249 blastocysts formed, 200 were cryopreserved for future use after undergoing PGT-A evaluation. Of those, 42.5% were diagnosed as euploid, 39.0% as aneuploid, 9.0% as mosaic and 9.5% had no result. When compared to CP-F, partialCPs exhibited a significantly greater percentage of mosaic embryos (3.6% v. 15.6%, p = 0.032). Additionally, we found that a greater percentage of embryos demonstrating CP-F exhibited morphokinetics that fell into optimal ranges for embryo development when compared to those with partial compaction patterns. CONCLUSION: Time-lapse visualization of compaction patterns identified exclusions and/or extrusions as negative indicators of blastocyst formation and blastocyst grade. When compared to full compaction patterns, partial compaction patterns were associated with delayed embryonic development as well as lower rates of optimal kinetic development.

Fertility-Preserving Surgical Management of a Cesarean Section Scar Ectopic Pregnancy.

STUDY OBJECTIVE: To demonstrate techniques used for fertility-preserving surgical management of a cesarean scar ectopic pregnancy. DESIGN: A narrated video case report demonstrating techniques and surgical approach. SETTING: With the increasing number of cesarean deliveries being performed, cesarean scar ectopic pregnancies (CSEP) have an increasing incidence affecting approximately 1 in 2000 pregnancies. CSEP can be associated with serious complications, which include maternal hemorrhage, uterine rupture, and even maternal death. This video highlights a case presentation of a 28-year-old G6P4014 with a history of 4 previous cesarean deliveries who presented with a persistent cesarean scar ectopic pregnancy that had failed previous medical management. INTERVENTIONS: This video highlights the techniques that allow for fertility-preservation with restoration of normal anatomy as well as minimizing blood loss with a potentially morbid procedure. Techniques used to allow for fertility preservation with restoration of normal anatomy: 1. Utilization of avascular spaces and identification of critical structures to restore anatomy that is often distorted by the CSEP. 2. Limited use of electrosurgery to allow for adequate postoperative healing. 3. Identification of the endometrial cavity to allow for complete removal of the CSEP and isthmocele repair. Techniques used to minimize blood loss: 1. Intracervical injection of dilute vasopressin. 2. Intrauterine injection of dilute vasopressin (20U in 60 cc of injectable saline). 3. Temporary occlusion of bilateral gonadal vessels using surgical clips. CONCLUSION: The surgical techniques highlighted in this video allow for the surgical removal of a cesarean scar ectopic pregnancy with concurrent repair of the uterine defect, allowing for restoration of normal anatomy. This is a safe and feasible fertility-preserving option that can be performed using a minimally-invasive approach.

The impact of endometriosis on embryo morphokinetics: embryos from endometriosis patients exhibit delayed cell cycle milestones and decreased blastulation rates.

PURPOSE: To compare morphokinetic parameters in embryos obtained from women with and without endometriosis. METHODS: We evaluated a total of 3471 embryos resulting from 434 oocyte retrievals performed at a single academic center. One thousand seventy-eight embryos were obtained from women affected by endometriosis and 2393 came from unaffected controls. All embryos were cultured in a time-lapse incubator chamber for up to 6 days. IVF cycle outcomes and morphokinetic parameters collected prospectively were retrospectively reviewed. RESULTS: Morphokinetic data suggest that embryo development is impaired in embryos obtained from women with endometriosis (EE). EE were slower to achieve the 2-8 cell stages compared to control embryos (CE) (p < 0.001); additionally, time to compaction was delayed compared to CE (p = 0.015). The timing of late developmental events, including morulation and blastulation was also delayed in the endometriosis cohort (p < 0.001). In addition to demonstrating delayed cell cycle milestones, EE were less likely than controls to progress to morula, blastocyst, and expanded blastocyst stages (p < 0.001). Furthermore, a smaller proportion of embryos in the endometriosis group fell into optimal kinetic ranges for cc2 (p = 0.003), t5 (p = 0.019), tSB (p < 0.001), and tEB (p = 0.007). There were no significant differences in clinical pregnancy or live birth rates between groups. CONCLUSION: Embryos from endometriosis patients demonstrate impairments in both early and late developmental events, and progress to the morula, blastocyst, and expanded blastocyst stages at lower rates than control embryos. Despite these differences, IVF outcomes are similar for patients with and without endometriosis.

Thickened Endometrium in Postmenopausal Women With an Initial Biopsy of Limited, Benign, Surface Endometrium: Clinical Outcome and Subsequent Pathologic Diagnosis.

Endometrial biopsy or curetting is indicated for postmenopausal women with abnormal uterine bleeding and/or thickened endometrium. Often, endometrial biopsy or curetting yields limited benign surface endometrium, which may indicate insufficient sampling. This study addresses the clinical outcome and subsequent pathologic diagnoses in postmenopausal women who received this initial diagnosis. Among a total of 370 endometrial biopsy or curetting between 2012 and 2015, 192 (52%) were diagnosed as limited benign surface endometrial epithelium. The women ranged in age from 55 to 91 yr old. Their clinical presentations mainly included postmenopausal bleeding, pelvic pain, and enlarged uterus. Primarily because the initial report was interpreted as "benign," 108 (57%) had no subsequent follow-up. Interestingly, women with an increased endometrial thickness were more likely to receive repeat evaluation. Among the 84 women who underwent follow-up endometrial sampling, 6 (7%) had hyperplasia with atypia or malignancy, 21 (25%) had a repeat diagnosis of limited surface sample, 4 (5%) had insufficient materials, and 53 (63%) had other benign findings. Among the subset of women who did receive subsequent follow-up, endometrial atypia or malignancies are more likely found in those with increased body mass index. In conclusion, a slight majority of women with postmenopausal bleeding and/or thickened endometrium had an initial limited surface endometrial sample. Most had no subsequent endometrial sampling. Among those with subsequent follow-up, the majority had benign findings. The study highlights the inconsistencies in adequacy criteria for endometrial sampling and the lack of standardization of subsequent management.

Impact of Laparoscopic Hysterectomy on Quality of Life.

There is an ongoing debate regarding the benefits and drawbacks of the various routes of hysterectomy. A number of studies have examined overall quality of life outcomes as well as specific patient-reported outcomes including physical, psychosocial, and sexual functioning after hysterectomy. Existing studies have used varied methodologies with widely heterogeneous results, but patient satisfaction appears to be very high after laparoscopic hysterectomy, with many studies favoring the laparoscopic approach over other routes of hysterectomy. There are many opportunities for further investigation into the impact of laparoscopic hysterectomy on quality of life-an outcome measure that may be 1 of the most important in surgeries for benign indications.

Uterine Factor Infertility: A Clinical Review.

Uterine factor infertility (UFI) may affect up to 1 in 500 reproductive age women. The uterus is an essential component of achieving pregnancy and carrying a pregnancy to term successfully. There are many etiologies of UFI which may be categorized into either congenital or acquired causes. In this review, we discuss the different causes of UFI as well as the treatment options, which now includes uterine transplant.

Laparoscopic transfundal approach to cervical dilation: a novel treatment for cervical stenosis and cervical factor infertility.

OBJECTIVE: To demonstrate a novel technique used to restore cervical patency in a patient with severe iatrogenic cervical stenosis. DESIGN: Surgical video case report. SETTING: A single academic institution. PATIENT(S): We highlight the case of a 35-year-old nulliparous woman with a history of primary infertility. Her past medical history was significant for focal, invasive, well-differentiated squamous cell carcinoma of the cervix, for which she underwent a loop electrosurgical excision procedure. During her infertility assessment, she was found to have an extremely stenotic cervix that was refractory to conventional treatment options. INTERVENTIONS: This video highlights our innovative laparoscopic transfundal technique used to restore her cervical patency. MAIN OUTCOME MEASURES: None, as this is a descriptive case report. RESULTS: Postoperatively, the patient had continued cervical patency for >1 year with successful fertility treatment resulting in pregnancy. CONCLUSIONS: To our knowledge, this is the first case report describing a laparoscopic transfundal approach used to reestablish cervical patency. This approach may be considered for patients with cervical stenosis who have not responded to standard conservative therapies.

Fertility Preservation in Women with Endometriosis.

Several mechanisms have been implicated in the pathogenesis of endometriosis-related infertility. For patients considering surgery, the risk of iatrogenic injury is among the most important factors in the context of fertility preservation, along with age and individual reproductive goals. In the case of endometrioma excision, evidence overwhelmingly demonstrates the negative impact of surgery on ovarian reserve, with significant reductions in antimullerian hormone (up to 30% in unilateral versus up to 44% in bilateral endometriomas). The surgical endometriosis patient should be thoroughly counseled regarding fertility preservation and discussion should include tissue, embryo, and oocyte cryopreservation options. For the latter, data support cryopreservation of 10-15 oocytes in women ≤35 years and over 20 for those >35 years for a realistic chance to achieve one or more live births. When performing surgical interventions for endometriosis, reproductive surgeons should employ fertility-conserving surgical methods to reduce the likelihood of postoperative iatrogenic diminished ovarian reserve.

Robotic treatment of bowel endometriosis.

Endometriosis describes a condition with the presence of ectopic endometrial glands and stroma outside the endometrial cavity that affects up to 15% of reproductive-aged women. Of women affected with endometriosis, 3.8-37% will have endometriosis involving the bowel, primarily the rectosigmoid colon. While medical management is often recommended as a first-line therapy, it is not curative, and surgery is often required as an adjunct for the management of symptoms. Minimally invasive surgery has become the standard of care for managing these patients. The use of robotic-assisted laparoscopy offers benefits that may allow surgeons to perform these challenging surgical cases using a minimally invasive technique. For lesions that affect the colon, there are three primary techniques used for removal which include: 1) rectal shaving, 2) discoid excision and 3) segmental resection. The decision to pursue one approach over another is largely dependent on the number of lesions present, a lesion's size and depth of invasion as well as the involved circumference of the bowel. The available evidence of using robotic-assisted laparoscopy in cases of bowel endometriosis is limited in the literature. In this review, we will summarize the role of robotic-assisted laparoscopy in the management of bowel endometriosis.

Impact of the COVID-19 Pandemic and Obstetrician and Gynecologist Workforce Distribution on Vaccine Deployment and Predicting Women's Healthcare Shortages.

Background Obstetricians and gynecologists, who serve a vital role in providing women's healthcare in the United States, are at risk of COVID-19 exposure via asymptomatic patients and deliveries. This study analyzes state-level geographical distribution of COVID-19 cases and age distribution of Obstetricians and gynecologists (OB/GYNs) to project which US regions will experience a more significant COVID-19 patient burden and provides a guide for vaccine distribution in the OB/GYN workforce. Methods The Association of American Medical Colleges' state-level workforce data is combined with COVID-19 case data reported by Johns Hopkins University. All data and code are available at https://github.com/cxr244/covid-obgyn. Results Our findings illustrate that OB/GYNs in the Midwestern region of the US experience the highest number of COVID-19 patients per OB/GYN over 60 years of age: North Dakota, South Dakota, Iowa, Wisconsin, and Idaho have the highest burden of COVID-19 patients per OB/GYN, warranting vaccine distribution priority. Additionally, states with the highest proportion of OB/GYNs over the age of 60 like Florida (38%), New Mexico (37%), Alabama (36%), California (36%), and New Jersey (34%), should be strongly considered for priority vaccine allocation, to mitigate predicted OB/GYN workforce shortages.  Conclusion When planning and executing vaccine allocation, especially in the early stages of distribution, it is critical to evaluate which communities can benefit the greatest from the limited number of vaccines. A strategy of distribution of COVID-19 vaccines to older physicians with a more significant COVID-19 burden can minimize shortages of providers within these states and ensure adequate access to women's healthcare within the communities they serve.

Effects of myomas and myomectomy on assisted reproductive technology outcomes.

OBJECTIVE: To determine the effects of fibroids, and their removal, on ART outcomes. MATERIALS AND METHODS: Single institution retrospective cohort study of infertility patients who underwent myomectomy prior to either in vitro fertilization (IVF) or intrauterine insemination (IUI) between August 2006 and October 2015 (N = 49). Two separate control groups were established: 1) women with fibroids left in situ during the ART process (N = 76), and 2) women with no fibroids (N = 103). The study was powered to detect a difference between a 42%, 11%, and 25% live birth (LB) rate in the myomectomy, fibroids in situ, and no fibroids groups at P < 0.05. RESULTS: There were no significant differences in IVF cycle parameters between groups. Fibroids that were either submucosal or intramural with associated cavity distortion were significantly more likely to be removed. Amongst women undergoing IVF, the cumulative incidence of clinical pregnancy (CP) was significantly higher in the myomectomy group than the in situ or no fibroids groups. Women who underwent pre-IVF myomectomy also achieved CP more quickly. Cumulative LB rates did not differ significantly amongst women undergoing IVF. CP and LB rates per cycle were similar between myomectomy, in situ, and no fibroids groups (CP 49% vs. 37.5% vs. 54.4%, P = 0.21; LB 41.7% vs. 27.1% vs. 43.9%, P = 0.17). DISCUSSION: IVF outcomes appear to be improved by judicious removal of clinically significant fibroids. Further prospective studies are required to confirm the role of fibroids, and their removal, on ART outcomes before advocating for routine myomectomy amongst women with fibroids undergoing ART.
