Objective To characterize atypical dynamic embryo phenotypes identified by time-lapse microscopy, evaluate their prevalence, and determine their association with embryo development. Design Retrospective multicenter cohort study. Setting Five IVF clinics in the United States. Patient(s) Sixty-seven women undergoing IVF treatment with 651 embryos. Intervention(s) Embryo videos were retrospectively analyzed for atypical phenotypes. Main Outcome Measure(s) Identification of four groups of atypical embryo phenotypes: abnormal syngamy (AS), abnormal first cytokinesis (A1cyt), abnormal cleavage (AC), and chaotic cleavage (CC). Prevalence and association with embryo morphology and development potential were evaluated. Result(s) A high prevalence of atypical phenotypes was observed among embryos: AS 25.1% (163/649), A1cyt 31.0% (195/639), AC 18% (115/639) and CC 15% (96/639). A high percentage of embryos with atypical phenotype(s) had good quality on day 3 (overall grade good or fair): AS 78.6% (70/89); A1cyt 79.7% (94/119), AC 86.4% (70/81), and CC 35.2% (19/54), but the blastocyst formation rates for these embryos were significantly lower compared with their respective control groups: AS 21.5% vs. 44.9%, A1cyt 21.7% vs. 44.6%, AC 11.7% vs. 43.1%, and CC 14.0% vs. 42.3%. Conclusion(s) Embryos exhibiting atypical phenotypes are highly prevalent in human embryos and show significantly lower developmental potential than control embryos.

Objective: To identify pre or post processing semen analysis parameters that may be predictive of successful pregnancy in couples with male factor infertility undergoing intra uterine insemination (IUI). To evaluate the pregnancy rate based on ovulation inducing agent in couples with male factor infertility per the 2010 world health organization criteria treated with IUI. Study design: This retrospective study was performed at Stanford University medical center. All couples with male factor infertility fitting inclusion criteria were included over a 2 year period of time. 147 couples with male factor infertility were included and 356 IUIs were analyzed. All subjects in this study had Kruger strict analysis >4% normal forms. Logistic regression analysis was used to control for confounding effects and multiplicity. Results: The overall pregnancy rate was 5.3%. No parameter in either the pre or post analysis predicted pregnancy. Furthermore, it was found that natural cycle and letrazole treatment had similar pregnancy rates (3% and 3%) p = ns. Similar outcomes were also observed between clomiphene citrate and gonadotropin stimulated cycles (7.5% and 6.0%) p = ns. Conclusions: Total motile sperm count which has been found to be a predictor of pregnancy when evaluated in isolation, may be due to a confounding effect. These low pregnancy rates should be considered when deciding whether to suggest IUI and when selecting a protocol for ovulation induction for couples with male factor infertility. © 2014 Elsevier Ireland Ltd.

Objective: To assess the first computer-automated platform for time-lapse image analysis and blastocyst prediction and to determine how the screening information may assist embryologists in day 3 (D3) embryo selection. Design: Prospective, multicenter, cohort study. Setting: Five IVF clinics in the United States. Patient(s): One hundred sixty women ≥18 years of age undergoing fresh IVF treatment with basal antral follicle count ≥8, basal FSH <10 IU/mL, and ≥8 normally fertilized oocytes. Intervention(s): A noninvasive test combining time-lapse image analysis with the cell-tracking software, Eeva (Early Embryo Viability Assessment), was used to measure early embryo development and generate usable blastocyst predictions by D3. Main Outcome Measure(s): Improvement in the ability of experienced embryologists to select which embryos are likely to develop to usable blastocysts using D3 morphology alone, compared with morphology plus Eeva. Result(s): Experienced embryologists using Eeva in combination with D3 morphology significantly improved their ability to identify embryos that would reach the usable blastocyst stage (specificity for each of three embryologists using morphology vs. morphology plus Eeva: 59.7% vs. 86.3%, 41.9% vs. 84.0%, 79.5% vs. 86.6%). Adjunctive use of morphology plus Eeva improved embryo selection by enabling embryologists to better discriminate which embryos would be unlikely to develop to blastocyst and was particularly beneficial for improving selection among good-morphology embryos. Adjunctive use of morphology plus Eeva also reduced interindividual variability in embryo selection. Conclusion(s): Previous studies have shown improved implantation rates for blastocyst transfer compared with cleavage-stage transfer. Addition of Eeva to the current embryo grading process may improve the success rates of cleavage-stage ETs. Copyright © 2013 American Society for Reproductive Medicine, Published by Elsevier Inc.

This article focuses on the cause, pathophysiology, differential diagnosis of, and treatment options for vasomotor symptoms. In addition, it summarizes important points for health care providers caring for perimenopausal and postmenopausal women with regard to health maintenance, osteoporosis, cardiovascular disease, and vaginal atrophy. Treatment options for hot flashes with variable effectiveness include systemic hormone therapy (estrogen/progestogen), nonhormonal pharmacologic therapies (selective serotonin reuptake inhibitors, selective norepinephrine reuptake inhibitors, clonidine, gabapentin), and nonpharmacologic therapy options (behavioral changes, acupuncture). Risks and benefits as well as contraindications for hormone therapy are further discussed. © 2015 Elsevier Inc.

Preimplantation genetic diagnosis (PGD) is an increasingly common adjunct to IVF. The information gained from PGD may be used to reduce the incidence of chromosomally abnormal pregnancies and augment the current selection process of embryos. As such, patients may choose to utilize PGD in either fresh or cryopreserved IVF cycles. It is a common practice to cryopreserve excess embryos at the blastocyst stage. In these cases, trophectoderm biopsy is the only technique available for PGD. This articles reports this study centre's experience with trophectoderm biopsies of cryopreserved blastocysts in 12 patients who underwent 13 cycles of PGD. The implantation rate per embryo transferred was 46% and the ongoing pregnancy rate per embryo transfer was 63%. The results from this case series demonstrate that trophectoderm biopsy on cryopreserved blastocysts to perform PGD is logistically feasible. In addition, the rate of implantation and ongoing pregnancy were maintained within a reasonable range to justify the procedure. Preimplantation genetic diagnosis (PGD) is an increasingly common adjunct to IVF and is used to evaluate the genetic makeup of the embryo prior to transfer of the embryo into the uterus. The information gained from PGD may be used to identify single-gene disorders that result in genetic disease, reduce the incidence of chromosomally abnormal pregnancies and/or augment the selection process of embryos to be transferred. In order to perform PGD, a biopsy of the embryo is the performed and cells are removed for testing. PGD may be performed in either fresh or frozen (cryopreserved) IVF cycles. Patients who have cryopreserved embryos remaining in storage from a previous fresh cycle may wish to have these embryos tested with PGD. Many embryos are frozen on day 5 of development, referred to as the blastocyst stage. At this stage of development, embryo biopsy is performed via a technique known as 'trophectoderm biopsy', in which 1-3 of the cells destined to become the placenta are removed from the embryo for chromosomal testing. We report our experience with trophectoderm biopsy of frozen blastocysts in 12 patients who underwent 13 cycles of PGD. The implantation rate per embryo transferred was 46% and the ongoing pregnancy rate per embryo transfer was 63%. The results from this case series demonstrate that trophectoderm biopsy on cryopreserved blastocysts to perform PGD is logistically feasible. In addition, the rate of implantation and ongoing pregnancy were maintained within a reasonable range to justify the procedure. © 2012, Reproductive Healthcare Ltd. Published by Elsevier Ltd.
