A fundamental study by Ens et al. (1992, Journal of Animal Ecology, 61, 703) developed the concept of two different nest-territory qualities in Eurasian oystercatchers (Haematopus ostralegus, L.), resulting in different reproductive successes. "Resident" oystercatchers use breeding territories close to the high-tide line and occupy adjacent foraging territories on mudflats. "Leapfrog" oystercatchers breed further away from their foraging territories. In accordance with this concept, we hypothesized that both foraging trip duration and trip distance from the high-tide line to the foraging territory would be linearly related to distance between the nest site and the high tide line...

Women have a lifetime risk of major depression double that of men but only during their reproductive years. This sex difference has been attributed partially to activational effects of female sex steroids and also to the burdens of pregnancy, childbirth, and parenting. Men, in contrast, have a reproductive period difficult to delineate, and research on the mental health of men has rarely considered the effects of fatherhood. However, the couple goes through a number of potentially stressing events during the reproductive period, and both mothers and fathers are at risk of developing peripartum depression...

Meiotic progression in mammalian preovulatory follicles is controlled by the granulosa cells around the oocyte. Cyclic GMP (cGMP) generated in the granulosa cells diffuses through gap junctions into the oocyte, maintaining meiotic prophase arrest. Luteinizing hormone then acts on receptors in outer granulosa cells to rapidly decrease cGMP. This occurs by two complementary pathways: cGMP production is decreased by dephosphorylation and inactivation of the NPR2 guanylyl cyclase, and cGMP hydrolysis is increased by activation of the PDE5 phosphodiesterase...

PURPOSE OF REVIEW: Wolbachia is a genus of Gram-negative intracellular bacteria that is naturally found in more than half of all arthropod species. These bacteria cannot only reduce the fitness and the reproductive capacities of arthropod vectors, but also increase their resistance to arthropod-borne viruses (arboviruses). This article reviews the evidence supporting a Wolbachia-based strategy for controlling the transmission of dengue and other arboviral infections. RECENT FINDINGS: Studies conducted 1 year after the field release of Wolbachia-infected mosquitoes in Australia have demonstrated the suppression of dengue virus (DENV) replication in and dissemination by mosquitoes...

Among the components of the female reproductive tract, the ovarian pool of follicles and their enclosed oocytes are highly sensitive to hyperthermia. Heat-induced alterations in small antral follicles can be expressed later as compromised maturation and developmental capacity of the ovulating oocyte. This review summarizes the most up-to-date information on the effects of heat stress on the oocyte with an emphasis on unclear points and open questions, some of which might involve new research directions, for instance, whether preantral follicles are heat resistant...

Suicide is a global public health problem. Media impact on suicide is well confirmed and there are several recommendations on how media should and should not report on suicide to minimize the risk of copycat behavior. Those media guidelines have been developed to improve responsible reporting on suicide (RRS). Although such guidelines are used in several countries, we lack empirical evidence on their causal effect on actual journalistic news writing. We conducted an experiment with journalism students (N = 78) in Germany in which we tested whether exposure to awareness material promoting RRS influences news writing...

The expectation of obstetrics is a perfect outcome. Obstetrics malpractice can cause morbidity and mortality that may engender litigation. Globally, increasing trend to litigation in obstetrics practice has resulted in high indemnity cost to the obstetrician with consequent frustration and overall danger to the future of obstetrics practice. The objective was to review litigations and the Obstetrician in Clinical Practice, highlighting medical ethics, federation of gynecology and obstetrics (FIGO's) ethical responsibility guideline on women's sexual and reproductive health and right; examine the relationship between medical ethics and medical laws; X-ray medical negligence and litigable obstetrics malpractices; and make recommendation towards the improvement of obstetrics practices to avert misconduct that would lead to litigation...

Early in pregnancy women and their partners face the complex decision on whether or not to participate in prenatal testing for fetal chromosomal abnormalities. Several studies show that the majority of pregnant women currently do not make informed decisions regarding prenatal testing. As the range of prenatal tests is expanding due to the development of new techniques such as non-invasive prenatal testing (NIPT), autonomous reproductive decision-making is increasingly challenging. In this study, a randomised controlled trial was conducted to evaluate the effect of a web-based multimedia decision aid on decision-making regarding prenatal testing...

With the increased international focus on personalized health care and preventive medicine, next-generation sequencing (NGS) has substantially expanded the options for carrier screening of serious, recessively inherited diseases. NGS screening tests not only offer reproductive options not previously available to couples, but they may also ultimately reduce the number of children born with devastating disorders. To date, preconception carrier screening (PCS) has largely targeted single diseases such as cystic fibrosis, but NGS allows the testing of many genes or diseases simultaneously...

Monica V Dragoman, Mary E Gaffield
CONTEXT: Depot medroxyprogesterone acetate (DMPA), a progestogen-only contraceptive injectable, has traditionally been formulated as a crystalline suspension delivered intramuscularly (IM) at a dose of 150mg/1.0mL. A new, lower dose formulation of DMPA (104mg/0.65mL) has been developed for subcutaneous administration (SC). Given its increasing global availability and public health relevance, DMPA-SC was prioritized for inclusion as a new method referenced in the World Health Organization (WHO) Medical Eligibility Criteria for Contraceptive Use (MEC), 5th Edition...

BACKGROUND: Human reproduction depends on an intact hypothalamic-pituitary-gonadal (HPG) axis. Hypothalamic gonadotrophin-releasing hormone (GnRH) has been recognized, since its identification in 1971, as the central regulator of the production and release of the pituitary gonadotrophins that, in turn, regulate the gonadal functions and the production of sex steroids. The characteristic peculiar development, distribution and episodic activity of GnRH-producing neurons have solicited an interdisciplinary interest on the etiopathogenesis of several reproductive diseases...

STUDY QUESTION: Can a tool be developed for authors, reviewers and editors of the ESHRE Journals to improve the quality of published studies which rely on semen analysis data? SUMMARY ANSWER: A basic checklist for authors, reviewers and editors has been developed and is presented. WHAT IS KNOWN ALREADY: Laboratory work which includes semen analysis is burdened by a lack of standardization. This has significant negative effects on the quality of scientific and epidemiological studies, potential misclassification of patients and the potential to impair clinical treatments/diagnoses that rely on accurate semen quality information...

Acute pelvic pain in premenopausal women frequently poses a diagnostic dilemma. These patients may exhibit nonspecific signs and symptoms such as nausea, vomiting and leukocytosis. The cause of pelvic pain includes a myriad of diagnostic possibilities such as obstetric, gynecologic, urologic, gastrointestinal, and vascular etiologies. The choice of the imaging modality is usually determined by a suspected clinical differential diagnosis. Thus the patient should undergo careful evaluation and the suspected differential diagnosis should be narrowed before an optimal imaging modality is chosen...

BACKGROUND: ICSI is currently the most commonly used assisted reproductive technology, accounting for 70-80% of the cycles performed. This extensive use, even excessive, is partly due to the high level of standardization reached by the procedure. There are, however, some aspects that deserve attention and can still be ameliorated. The aim of this systematic review was to evaluate the results of available publications dealing with the management of specific situations during ICSI in order to support embryologists in trying to offer the best laboratory individualized treatment...
