Although in vitro fertilization (IVF) has offered hope to those struggling with infertility, it has also had some unintended consequences, including the fate of embryos that may be "surplus" to requirement following IVF treatment. The number of embryos in storage across the world is high, creating a dilemma for patients who need to make disposal decisions, as well as presenting an administrative and practical dilemma for clinics. Research has suggested that patients' views of the status of their embryo/s may affect their disposal decisions, and yet the nature of the links between views of the embryo and decisions to either donate or discard remain unclear...

Sukhmanpreet Kaur, Vijay Kumar, Mohit Chawla, Luigi Cavallo, Albert Poater, Niraj Upadhyay
Researchers have suggested that the reason behind infertility is pernicious effect of broad spectrum pesticides on non target, beneficial microorganism of soil. Here, studying the chelating effect of selective organophosphate and carbamate pesticides with essential metal ions, at all possible combinations of three different pH (4 ± 0.05, 7 ± 0.05 and 9 ± 0.05) and three different temperatures (15 ± 0.5°C, 30 ± 0.5°C and 45 ± 0.5°C), shows very fast rate of reaction which further increases with increase of pH and temperature...

B Orrù, R Circo, P Logoteta, S Petousis, G Carlomagno
Broadening clinical evidence has markedly designated inositol(s) as a common and effective therapeutic approach for PCOS and infertility. Although considerable research has been focused on the use in clinical practice of myo-inositol (myo-ins) and D-chiro-inositol (D-chiro-ins), the two major inositol stereoisomers, less attention has been paid to their bioavailability. Therefore, the aim of this paper is to gather and analyze information on inositol(s) bioavailability, to better delineate its optimal concentration for scientific and clinical purposes...

REVIEW
Mikkel Fode, Ferdinando Fusco, Larry Lipshultz, Wolfgang Weidner
CONTEXT: Theoretically, sexually transmitted diseases (STDs) have the potential to disrupt male fertility; however, the topic remains controversial. OBJECTIVE: To describe the possible association between STDs and male infertility and to explore possible pathophysiologic mechanisms. EVIDENCE ACQUISITION: We performed a systematic literature review in accordance with the PRISMA guidelines. PubMed, Embase, and the Cochrane Library were searched for articles published before January 1, 2016, using the MeSH terms for a variety of STDs and infertility...

Maike Fliegner, Hertha Richter-Appelt, Kerstin Krupp, Franziska Brunner
Study 1 Development of the questionnaire Most questionnaires on attitudes toward motherhood presume that the subject is fertile and positive and negative attitudes are represented on a one-dimensional scale. Moreover, the questionnaires often do not provide German versions and German norms. The aim of this study is to examine whether the German Questionnaire on Attitudes toward Motherhood ("FEMu") can be used to describe attitudes toward motherhood multi-dimensionally and whether it is applicable independent of a person's fertility status...

REVIEW
A S Rex, J Aagaard, J Fedder
Sperm DNA Fragmentation has been extensively studied for more than a decade. In the 1940s the uniqueness of the spermatozoa protein complex which stabilizes the DNA was discovered. In the fifties and sixties, the association between unstable chromatin structure and subfertility was investigated. In the seventies, the impact of induced DNA damage was investigated. In the 1980s the concept of sperm DNA fragmentation as related to infertility was introduced as well as the first DNA fragmentation test: the Sperm Chromatin Structure Assay (SCSA)...

REVIEW
Yash S Khandwala, Chiyuan A Zhang, Shufeng Li, Mark R Cullen, Michael L Eisenberg
PURPOSE OF REVIEW: We sought to determine whether infertile men can accurately be identified within a large insurance claims database to validate its use for reproductive health research. RECENT FINDINGS: Prior literature suggests that men coded for infertility are at higher risk for chronic disease though it was previously unclear if these diagnostic codes correlated with true infertility. We found that the specificity of one International Classification of Disease (9th edition) code in predicting abnormal semen parameters was 92...

REVIEW
Dillon Sedaghatpour, Boback M Berookhim
PURPOSE OF REVIEW: Varicocele may play a significant role in a subset of patients presenting with male factor infertility. Despite its relatively high prevalence amongst subfertile men, there has been controversy over the effectiveness of surgical treatments, patient selection, and when to administer treatment, particularly in the era of assisted reproductive technology. RECENT FINDINGS: In line with earlier finding, recent evidence strongly suggests that varicocelectomy improves pregnancy rates and semen parameters...

INTRODUCTION: Sickle cell disease (SCD) is a chronic genetic disease with high morbidity and early mortality; it affects nearly 100,000 individuals in the USA. Bone marrow transplantation, the only curative treatment, is available to less than 20% of patients because of a number of access barriers. Gene transfer therapy (GTT) has been shown to be curative in animal models and is approved for use in humans for early-phase studies at a few centers. GTT would offer a more accessible treatment option available to all patients...

BACKGROUND: Children, adolescents, and young adults (children/youth) with differences/disorders of sex development (DSD) face challenges related to future fertility; this may be due to variations in gonadal development, and, for some, gonadectomy performed to reduce the risk of malignancy. Childhood may be the only time for preservation of biological fertility potential for children/youth who undergo gonadectomy or have early gonadal failure. Fertility-related decision-making for these patients is particularly complicated, due to the need for parental proxy decision-making, potential discordance between gender identity and gonadal type, and uncertain future assisted reproductive technologies...

BACKGROUND: Infertility has been shown to have considerable psychological effects on the well-being of couples, especially women. Religion has been found as a resource used by infertile women to cope with their distress. Little research has examined the influence of religious coping on psychological distress among infertile women in Ghana. This study examines the relationship between positive and negative religious coping and psychological health for women with infertility problems in Ghana...

Antonella Smeriglio, Marcella Denaro, Domenico Trombetta
Phytochemicals are non-nutrient bioactive compounds that occur in plant and food which possess the capacity to modulate one or more metabolic processes or pathways in the body, resulting to health benefits and promotion of well-being. At this regard, the interest of the scientific community continues to grow, powered by progressive research efforts to identify properties and potential applications of bioactive substances, and coupled with public interest and consumer demand. However, the natural derivation of these compounds is not a feature of harmlessness, over that of therapeutic efficacy, to which is also added the absence of post-marketing monitoring that does not allow to evaluate the occurrence of adverse effects related to the use of their related products...

OBJECTIVE: Little is known about how women with isolated GnRH deficiency cope with their condition. This study aimed to examine the health and informational needs of women with congenital hypogonadotropic hypogonadism (CHH) and evaluate if their experiences differ from women with more common forms of infertility. DESIGN: Cross-sectional, multiple methods study using web-based data collection to reach dispersed rare disease patients. METHODS: A community-based participatory research framework was employed to develop an online survey and collect quantitative and qualitative data...

William D Schlaff
The alarming trend in opiate misuse in developed countries is prompting an increasingly strident public call for action. Although many in our field have assumed that this building crisis does not really affect us or our patients, data show that the emerging demographic at highest risk for misusing opiates clearly includes patients who seek care in our practices. The goals of this Views and Reviews are to provide a clear understanding of emerging trends in opiate misuse, to review the impact of opiates on the reproductive axis, and to suggest practical recommendations aimed at both mitigating iatrogenic influences on promoting misuse and developing treatment frameworks when misuse is suspected or identified...

REVIEW
Jamie P Dubaut, Nelson I Agudelo Higuita, Alexander M Quaas
In the past 2 years, Zika virus has emerged from obscurity onto the world stage-traversing and transcending clinical specialties, basic science disciplines, and public health efforts. The spread of Zika virus has serious implications for the specialty of reproductive endocrinology and infertility. Our patients, practices, and labs-worldwide and specifically in the USA-have been impacted by this teratogenic, sexually transmitted, largely asymptomatic virus. While the World Health Organization's Public Emergency of International Concern designation has lapsed as major epidemics have subsided and understanding of risks is in part clarified, the acute and long-term threat to pregnant patients is not over...

Absolute uterine factor infertility, with a uterine absence or presence of a nonfunctional uterus, has during the last decades been the only remaining, major group of female infertility. Uterus transplantation (UTx) has now emerged as the first therapy for these women that have traditionally been regarded as unconditionally infertile. Areas covered: This review summarizes the research preparations in several experimental animal species that paved the way for the clinical introduction of UTx. The article also describes the human UTx attempts that have been reported up until today and the several live births that have occurred after the initial UTx baby was born in 2014...

BACKGROUND: Infertility as a gynecological illness causes many psychological problems. In Turkey, only a limited number of studies have used qualitative methods to explore the experiences of infertile women. PURPOSE: The aims of this study are to investigate the infertility experiences of women using Watson's Theory of Human Caring as a guide and to sensitize healthcare professionals to the importance of the personal stories of these women. METHODS: A phenomenological approach was used to guide our exploration of the stories of infertile women during their treatment for infertility...

Organoid systems take advantage of the self-organizing capabilities of cells to create diverse multi-cellular tissue surrogates that constitute a powerful novel class of biological models. Clearly, the formation of a testicular organoid (TO) in which human spermatogenesis can proceed from a single-cell suspension would exert a tremendous impact on research and development, clinical treatment of infertility, and screening of potential drugs and toxic agents. Recently, we showed that primary adult and pubertal human testicular cells auto-assembled in TOs either with or without the support of a natural testis scaffold...

OBJECTIVE: After the introduction of assisted reproductive techniques, human embryos were officially introduced into laboratories and now thousands of them are cryopreserved in such settings. Embryonic stem cells and the future application of such cells in the treatment of disease opened the door to further research on human embryos. These developments raise many ethical issues, some of which have religious aspects. The main question is: what is the embryo? Should we consider it a human being? Thus, the purpose of this study was to investigate attitudes towards the personhood of the embryo...

OBJECTIVE: The properties of self-renewal and division in spermatogonial stem cells (SSCs) support spermatogenesis. There is a number of reported methods for in vitro SSC culture systems. The development of a culture system that effectively supports isolation and selfrenewal of germline stem cells (GSCs) is of tremendous benefit for clinical trials, experimental research, and as potential treatment for male infertility. The current study aims to consider the cultivation and behavior of GSCs in a non-adherent culture system...
