Autologous endometrial cell co-culture improves human embryo development to high-quality blastocysts: a randomized controlled trial.

RESEARCH QUESTION: Does autologous endometrial cell co-culture (AECC) improve the number of good-quality blastocysts obtained by IVF/intracytoplasmic sperm injection (ICSI), compared with conventional embryo culture medium in a broad group of patients referred to assisted reproductive technology (ART)? DESIGN: This interventional, randomized, double-blind study took place at Clinique Ovo from March 2013 to October 2015 and included 207 healthy patients undergoing an IVF or ICSI protocol, of which 71 were excluded before randomization. On the previous cycle, all participants underwent an endometrial biopsy at D5 to D7 post-ovulation, following which the endometrial cells were prepared for AECC. RESULTS: The data demonstrated that AECC significantly increased the incidence of good-quality blastocysts compared with culture in conventional media (42.6% vs 28.4%, P < 0.001). No significant differences were found in pregnancy and live birth rates. CONCLUSION: This study demonstrated the benefits of AECC on blastocyst quality compared with conventional embryo culture medium, in a broader category of patients referred to ART as opposed to other studies that concentrated on specific causes of infertility only. However, limitations of the study design should be taken into consideration; the analysis was performed using embryos rather than patients and a follow-up of children born following the treatments could not be conducted.

No. 356-Egg Freezing for Age-Related Fertility Decline.

OBJECTIVE: To provide a comprehensive review and evidence based recommendations for Canadian fertility centres that offer social egg freezing. OUTCOMES: In social egg freezing cycles we evaluated thawed oocyte survival rates, fertilization rates, embryo quality, pregnancy rates, and live birth rates. We also review how these outcomes are impacted by age, ovarian reserve, and the number of eggs cryopreserved. Finally, we discuss the risks of social egg freezing, the alternatives, the critical elements for counselling and informed consent, and future reporting of egg freezing outcome data. EVIDENCE: Published literature was reviewed through searches of MEDLINE and CINAHL using appropriate vocabulary and using key words ("oocyte cryopreservation," "egg freezing," "egg vitrification," "social egg freezing," and "elective egg freezing"). Results included systematic reviews, randomized controlled trials, controlled clinical trials, and observational studies. Expert opinion based on clinical experience, descriptive studies, or reports of expert committees was also included to discuss aspects of egg freezing not currently rigorously studied. VALUES: The evidence obtained was reviewed and evaluated by the Clinical Practice Guideline (CPG) Committees of the Canadian Fertility and Andrology Society (CFAS) under the leadership of the principal authors. BENEFITS, HARMS, AND COSTS: Implementation of this guideline should assist the clinician to develop an optimal approach in providing counselling for egg freezing while minimizing harm and improving patient outcomes during treatment. VALIDATION: These guidelines have been reviewed and approved by the membership of the CFAS and by the CPG Committees of CFAS and The Society of Obstetricians and Gynaecologists of Canada (SOGC). SPONSORS: CFAS and SOGC.

Outcomes of 1503 cycles of modified natural cycle in vitro fertilization: a single-institution experience.

PURPOSE: A retrospective cohort study was conducted in a single academic center to determine if modified natural cycle in vitro fertilization (mnIVF) is an acceptable treatment for the infertile couple. METHODS: Cycles performed between July 2005 and December 2011 were included. In our center's mnIVF protocol, a GnRH antagonist, gonadotrophin, as well as Indocid are given on a daily basis from detection of a dominant follicle until ovulation induction. The primary outcomes were clinical pregnancy rates (CPR) per cycle started and per embryo transfer (ET). Outcomes were stratified by female patient age (≤35 years and ≥36 years). They were further stratified in each age group by ovarian response status according to the 2011 Bologna criteria. RESULTS: A total of 1503 cycles of mnIVF, performed in 782 patients, were analyzed. CPRs were 13.7 % per started cycle and 32.5 % per ET. Stratification by ovarian response status (normal or poor) in each age group showed similar CPRs in patients ≤35 years (p = 0.373), and divergent CPRs per ET in patients ≥36 years old (26.26 vs 6.25 %). CONCLUSION: MnIVF is an acceptable treatment option for patients considering IVF, particularly for women ≤35 years old and for women ≥36 years old with normal ovarian response.

Relationship between body mass index and robotic surgery outcomes of women diagnosed with endometrial cancer.

OBJECTIVE: This is a prospective evaluation of the outcome of minimal invasive surgery using robotics in function of the body mass index (BMI) of patients. METHODS: This is a prospective cohort study of consecutive women undergoing surgery for endometrial cancer at a tertiary care facility since the initiation of a robotic program in December 2007. Surgical and personal outcome variables as well as quality of life and postoperative recovery were assessed using a combination of objective and subjective/self-report questionnaires. Women were divided into 3 groups based on their BMI. Comparative analyses among nonobese (n = 52), obese (n = 33) and morbidly obese (n = 23) women were performed on the outcome measures after surgery. RESULTS: The mean BMI and the range in each of the BMI categories was 25 kg/m² (18.7-29.4 kg/m²), 34 kg/m² (30.1-38.4 kg/m²), and 46 kg/m² (40.0-58.8 kg/m²). Women with higher BMI tended to be more frequently affected with comorbidities such as diabetes (15.4%, 26.0%, and 27.3%, respectively; P = 0.32) and hypertension (55.8%, 69.6%, and 69.7%, respectively; P = 0.19). Despite these differences, surgical console time (P = 0.20), major postoperative complications (P = 0.52), overall wound complications (P = 0.18), and median length of hospitalization in days (P = 0.17) were not statistically different among the 3 groups. Only 5.6% of women needed a mini laparotomy all of which were performed for the removal of their enlarged uterus, which could not be delivered safely via the vagina, at the end of the surgical procedure. There was no increased conversion to laparotomy due to increased BMI. Women in all 3 groups reported rapid resumption of hygiene regimens and chores, little need for narcotic analgesia, and high satisfaction with the procedure. CONCLUSIONS: Obese and morbidly obese patients with endometrial cancer are also good candidates for robotic surgery. These women benefit considerably from minimal invasive surgery and have little perioperative complications.

Creating a Global Community of Practice for Oncofertility.

Fertility preservation in the cancer setting, known as oncofertility, is a field that requires cross-disciplinary interaction between physicians, basic scientists, clinical researchers, ethicists, lawyers, educators, and religious leaders. Funded by the National Institutes of Health, the Oncofertility Consortium (OC) was formed to be a scientifically grounded, transparent, and altruistic resource, both intellectual and monetary, for building this new field of practice capable of addressing the unique needs of young patients with cancer. The OC has expanded its attention to include other nonmalignant conditions that can threaten fertility, and the work of the OC now extends around the globe, involving partners who together have created a community of shared effort, resources, and practices. The OC creates materials that are translated, disseminated, and amended by all participants in the field, and local programs of excellence have developed worldwide to accelerate the pace and improve the quality of oncofertility research and practice. Here we review the global oncofertility programs and the capacity building activities that strengthen these research and clinical programs, ultimately improving patient care.

Sarcoma post-embolization for presumed uterine fibroids.

BACKGROUND: Uterine artery embolization has increasingly been used in the last decade as a conservative treatment approach for uterine fibroids. Rarely sarcomas have been diagnosed shortly after uterine artery embolization. It remains unclear whether a change in diagnostic work-up is required prior to uterine artery embolization in order to avoid missing sarcomas and delaying definitive treatment. CASE: A 45 year old underwent uterine artery embolization for symptomatic uterine fibroids. Six months later, following progressive symptoms, she underwent surgery which revealed an endometrial stromal sarcoma. This manuscript raises the issue and reviews the existing literature concerning the need of tissue diagnosis prior to uterine artery embolization. CONCLUSION: Assessing the risk of malignancy by taking into account the clinical symptoms, physical exam, and imaging findings is essential prior to uterine artery embolization.

Ovarian function after uterine artery embolization and hysterectomy.

STUDY OBJECTIVE: To evaluate the effect of uterine artery embolization (UAE) and hysterectomy on ovarian function. DESIGN: Prospective case control study (Canadian Task Force classification II-2). SETTING: University teaching hospital. PATIENTS: Eighty-four healthy premenopausal women with symptomatic uterine myoma(s) undergoing UAE or hysterectomy. INTERVENTION: Patients had blood drawn to measure follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) levels and underwent transvaginal ultrasound to measure volume of the myoma(s) and uterus on cycle day 3 before the procedures. These measurements were repeated 3 and 6 months after treatment. MEASUREMENTS AND MAIN RESULTS: The main outcome was the differences in serum FSH, LH, E2, and ultrasound findings before and after UAE or hysterectomy. Of the 68 patients who underwent UAE and 16 who underwent hysterectomy, 48 and 13 respectively, completed 6-month follow-up. The mean age of the patients in the UAE group was 44.9 +/- 3.8 years and 43.7 +/- 5.6 years in the hysterectomy group. There was no significant difference in serum FSH before (8.9 +/- 0.7 IU/L) and 6 months after UAE (9.9 +/- 1.0 lU/L), and between the baseline (10.4 +/- 1.8 lU/L) and 6 months posthysterectomy (7.8 +/- 1.8 lU/L). The uterine volume 6 months after UAE (361 +/- 50 mL) was significantly smaller than before UAE(538 +/- 38mL; p =.005, 95% CI 44-241). Compared with baseline (154 +/- 20 mL), the dominant myoma volume was smaller at 6 months after UAE (97 +/- 16 mL; p <.05, 95% CI 1.57-62). CONCLUSION: Uterine artery embolization is associated with a significant reduction in myoma and uterine volume. Ovarian function at 6 months, as indicated by day 3 FSH levels, is not affected by UAE or hysterectomy.
