Laser-Assisted Zona Pellucida Thinning Does Not Facilitate Hatching And May Disrupt The In Vitro Hatching Process: A Morphokinetic Study In The Mouse, T. Schimmel, J. Cohen, H. Saunders, M. Alikani

Journal Articles

STUDY QUESTION: Does laser-assisted zona thinning of cleavage stage mouse embryos facilitate hatching in vitro? SUMMARY ANSWER: No, unlike laser zona opening, zona thinning does not facilitate embryo hatching. WHAT IS KNOWN ALREADY: Artificial opening of the zona pellucida facilitates hatching of mouse and human embryos. Laser-assisted zona thinning has also been used for the purpose of assisted hatching of human embryos but it has not been properly investigated in an animal model; thinning methods have produced inconsistent clinical results. STUDY DESIGN, SIZE, DURATION: Time-lapse microscopy was used to study the hatching process in the mouse after zona opening and …

BACKGROUND

Clomiphene is the current first-line infertility treatment in women with the polycystic ovary syndrome, but aromatase inhibitors, including letrozole, might result in better pregnancy outcomes.

Full Text of Background...

METHODS

In this double-blind, multicenter trial, we randomly assigned 750 women, in a 1:1 ratio, to receive letrozole or clomiphene for up to five treatment cycles, with visits to determine ovulation and pregnancy, followed by tracking of pregnancies. The polycystic ovary syndrome was defined according to modified Rotterdam criteria (anovulation with either hyperandrogenism or polycystic ovaries). Participants were 18 to 40 years of age, had at least one patent fallopian …

Contraceptive Sabotage, Leah A. Plunkett

Law Faculty Scholarship

This Article responds to the alarm recently sounded by the American College of Obstetricians and Gynecologists over “birth control sabotage”—the “active interference [by one partner] with [the other] partner’s contraceptive methods in an attempt to promote pregnancy.” Currently, sabotage is not a crime, and existing categories of criminal offenses fail to capture the essence of the injury it does to victims. This Article argues that sabotage should be a separate crime—but only when perpetrated against those partners who can and do get pregnant as a result of having sabotaged sex. Using the principle of self-possession—understood as a person’s basic right …

Community & Environmental Health Faculty Publications

Hot yoga establishments have been increasing in popularity in local communities. Studios may support participation among pregnant women though no clinical studies currently exist that examine prenatal hot yoga effects. The pilot study described in this article aimed to assess the spread of prenatal hot yoga and to provide information on the environmental conditions and practices of those who engage in hot yoga within a local community. A thermal environment meter was used to measure ambient air conditions during three 90-minute hot yoga classes. Mothers who practiced prenatal hot yoga were more likely than non-hot yoga practitioners to have someone …

Challenges And Considerations In Optimizing Ovarian Stimulation Protocols In Oncofertility Patients, Kathryn Coyne, Makenzie Purdy, Kathleen O'Leary, Jerome L. Yaklic, Steven R. Lindheim, Leslie A. Appiah

Obstetrics and Gynecology Faculty Publications

The scope of cancer treatment in women of childbearing age has changed in the last decade. Fertility preservation is no longer an afterthought but central to multi-disciplinary cancer treatment planning and should be addressed due to the cytotoxic effects of cancer therapy. However, oncology patients present as a unique treatment challenge as the physician must balance the urgency of fertility preservation with the risks of delaying cancer therapy. Controlled ovarian stimulation (COS) is routinely applied in assisted reproductive technology but can be contraindicated in women with estrogen-receptor-positive tumors. This paper reviews some of the challenges to consider when using COS …

The current study set out to identify and compare culture isolates of vaginal microflora of human immunodeficiency virus (HIV) positive (HIV+ ) and HIV negative (HIV- ) women at different phases during menstrual cycle from a sub-urban population of Kenya. Seventy four (74) women, 41 HIV+ and 33 HIV- , followed up two consecutive menstrual cycles, had high vaginal swabs taken to prepare Gram stains for six visits and anaerobic cultures for four. All 751 isolates identified by t-DNA polymerase chain reaction (PCR) belong to 51 species. …

Identifying Factors Associated With The Uptake Of Prevention Of Mother To Child Hiv Transmission Programme In Tigray Region, Ethiopia: A Multilevel Modeling Approach, Wondwossen Lerebo, Steven Callens, Debra Jackson, Christina Zarowsky, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: Prevention of mother to child HIV transmission (PMTCT) remains a challenge in low and middle-income countries. Determinants of utilization occur – and often interact - at both individual and community levels, but most studies do not address how determinants interact across levels. Multilevel models allow for the importance of both groups and individuals in understanding health outcomes and provide one way to link the traditionally distinct ecological- and individual-level studies. This study examined individual and community level determinants of mother and child receiving PMTCT services in Tigray region, Ethiopia.

Methods: A multistage probability sampling method was used for this …

Obstetrics and Gynaecology, East Africa

Objective: The main aim of this study was to assess whether a history of abuse, reported during pregnancy, was associated with an operative delivery. Secondly, we assessed if the association varied according to the type of abuse and if the reported abuse had been experienced as a child or an adult.

Design: The Bidens study, a cohort study in six European countries (Belgium, Iceland, Denmark, Estonia, Norway, and Sweden) recruited 6724 pregnant women attending routine antenatal care. History of abuse was assessed through questionnaire and linked to obstetric information from hospital records. The main outcome measure was operative delivery as …

Salomon, E. O. Ohuma, L. Cheikh Ismail, F. C. Barros, A. Lambert, Maria Carvalho, Y. A. Jaffer, E. Bertino, M. G. Gravett, D. G. Altman, M. Purwar, J. A. Noble, R. Pang, C. G. Victora, Z. A. Bhutta, J. Villar

Obstetrics and Gynaecology, East Africa

Objectives: There are no international standards for relating fetal crown–rump length (CRL) to gestational age (GA), and most existing charts have considerable methodological limitations. The INTERGROWTH-21^st Project aimed to produce the first international standards for early fetal size and ultrasound dating of pregnancy based on CRL measurement.

Methods: Urban areas in eight geographically diverse countries that met strict eligibility criteria were selected for the prospective, population-based recruitment, between 9 + 0 and 13 + 6 weeks' gestation, of healthy well-nourished women with singleton pregnancies at low risk of fetal growth impairment. GA was calculated on the basis of a …

Rwandan Young People’S Perceptions On Sexuality And Relationships: Results From A Qualitative Study Using The ‘Mailbox Technique’, Kristien Michielsen, Pieter Remes, John Rugabo, Ronan Van Rossem, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

This study aimed to gain more insight into young Rwandans’ perceptions on sex and relationships, which is essential for formulating effective sexual and reproductive health (SRH) promotion interventions. Using a ‘mailbox technique’, this paper studies the spontaneous thoughts of Rwandan young people on sexuality. Mailboxes were installed in five secondary schools in the Bugesera district and students were invited to write about their ideas, secrets, wishes, desires and fears on sexuality and relationships. Of the 186 letters collected, 154 addressed SRH topics. The letters were analysed in NVivo 9 using a theoretical model on vulnerability. Two stereotypical sexual interactions co-exist: …

Sexual Violence And Sub-Saharan Migrants In Morocco: A Community-Based Participatory Assessment Using Respondent Driven Sampling, Ines Keygnaert, Abdessamad Dialmy, Altay Manço, Jeroen Keygnaert, Nicole Vettenburg, Kristien Roelens, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: The European Union contracted Morocco to regulate migration from so-called “transit migrants” from Morocco to Europe via the European Neighbourhood Policy. Yet, international organisations signal that human, asylum and refugee rights are not upheld in Morocco and that many sub-Saharan migrants suffer from ill-health and violence. Hence, our study aimed at 1) investigating the nature of violence that sub-Saharan migrants experience around and in Morocco, 2) assessing which determinants they perceive as decisive and 3) formulating prevention recommendations.

Methods: Applying Community-Based Participatory Research, we trained twelve sub-Saharan migrants as Community Researchers to conduct in-depth interviews with peers, using Respondent …

Measuring The Impact Of Contraceptive Use On Unintended Pregnancy And Other Health Outcomes, Step Up Research Programme Consortium

Reproductive Health

This brief describes several statistical models that have been developed to estimate the number of health outcomes that will be averted because of contraceptive use. Concerns have been expressed that this range of approaches—which overlap in the impacts they estimate, but sometimes use different inputs, mathematical algorithms, and assumptions, and may produce different results—may be confusing for policymakers, managers, and donors who want to measure or evaluate these impacts. To address these concerns, the STEP UP consortium convened two expert meetings to review the estimation methods used; come to consensus on methodologies and assumptions, where possible; and provide guidance to …

Eating Disorders: The Hidden Hormonal Effect On Fertility, Esther Tessler-Karfunkel

The Science Journal of the Lander College of Arts and Sciences

Women who have a history of eating disorders, specifically anorexia nervosa, are more prone to suffer from infertility. There are several hormones which are the driving force in this system and are therefore responsible for this. Fortunately, there are treatments which can help women with a history of eating disorders to reproduce. Using information found on Pubmed and Touro College’s database, this paper will discuss why the body cannot reproduce when it is lacking proper nutrition, as well as the various dynamics in the human reproductive system which are compromised when the body is not properly nourished.

Association Between Parity And Rubella Seropositivity Among Older Reproductive-Age Women, Ibtisam Salim Awadh

Master of Medicine in Obstetrics and Gynecology

Background: Rubella virus when it infects a non-pregnant adult or child usually causes a mild febrile rash illness. However, infection in the first 12 weeks of pregnancy causes miscarriages, stillbirths or foetal anomalies known as congenital rubella syndrome (CRS). Factors associated with rubella immunity include age and parity. No studies have been done to isolate the association of parity independent of age. Objectives: To determine the seroprevalence of rubella IgG antibodies among nulliparous and multiparous women of the same age-group attending various clinics in Aga Khan University Hospital, Nairobi, Design: A cross-sectional study of women attending a tertiary hospital, Nairobi, …

A Mother's Paradox: Choosing A Birthing Method In The 21st Century, Jenae Franklin

Pitzer Senior Theses

Investigating childbirth, one of the biggest moments of a woman’s life, this thesis examines the reasons behind women’s preferred birthing methods. This research explores the fundamental decisions women make during the birthing process: the amount of prenatal care mothers will receive, the type of health care provider they will use, picking the place of delivery, views on technological and medical interventions, and outlooks on natural childbirth. In addition to an extensive literature review, in-depth interviews with mothers, midwives, and obstetricians are used to examine the various controversies of childbirth. This thesis begins with a review of the transition from midwives …
