The aim of this study was to test whether women who conceived after a period of subfertility are less likely to undergo invasive prenatal testing (IPT) and determine factors of influence in that decision. We conducted a retrospective study at the Maastricht University Medical Centre (MUMC+) to compare the rates of IPT following abnormal results of combined first trimester screening (cFTS) or second trimester screening (STS), or because of advanced maternal age among women tested for the effect of type and duration of subfertility and history of fertility investigations and/or treatment...

Biological parenthood is a central life-goal for many couples that can become blocked when they experience infertility. Many couples who undergo fertility treatment will face failure and consequently have to decide whether to continue with treatment. The present study used the qualitative methodology of Interpretative Phenomenological Analysis to examine self-regulatory approaches that underlie decision-making about continuing treatment. One-time, one-on-one, semi-structured, in-depth interviews were conducted with 16 individuals (eight heterosexual couples) after they had experienced at least one treatment failure and were considering whether to undergo another treatment...

As cancer survival rates continue to increase, so does the relevance of starting or expanding a family after cancer, impacting quality of life. However, the option of fertility preservation is not always addressed by physicians before treatment. In the meanwhile, many patients look for health information online. Although potentially helpful in the decision-making process, the Internet could also have adverse effects for this vulnerable patient group when information is incorrect. We aimed to assess the availability and quality of information on female oncofertility on websites of (inter)national oncology, fertility and oncofertility organizations...

Reduced sperm motility (asthenozoospermia) accounts for a significant percentage of male infertility and numerous factors have been suggested to explain this phenomenon among which hypoxic and inflammatory markers are the least studied. Therefore, the aim of this study was to assess the main molecular markers involved in hypoxia (P53 and HIF-1α) and inflammation (TNF-α) pathways in infertile men with asthenozoospermia. Expression of these markers were assessed by qRT-PCR, and analysis of data show that mean of hypoxia markers (P53, HIF-1α) and also TNF- α were significantly higher in infertile men with asthenozoospermia compared to fertile men (p < 0...

To date there is limited published data assessing whether body mass index (BMI) influences endometrial thickness (ET) and whether this impacts on pregnancy outcomes in single blastocyst FET cycles. The objective of this study, therefore, was to examine the relationship between BMI and ET on the outcome of single blastocyst FET cycles over a five-year period from 2012 until 2016. Patient age, BMI, endometrial pattern and ET prior to FET were recorded. Pregnancy outcomes included: implantation rate, clinical pregnancy rate and live birth rate...

Unexplained infertility refers to the absence of a definable cause of reproductive failure. Vitamin D receptor (VDR) acts as a transcription factor and regulates a number of vitamin D-responsive genes, including those involved in the immune system. Recent finding that VDR is expressed in reproductive tissues suggests a possible importance of vitamin D in pregnancy. We conducted a case-control study to examine the association of polymorphisms in VDR gene with reproductive success. DNA from 117 female patients with unexplained infertility and 130 fertile controls was isolated from peripheral blood and VDR genotypes (FokI, BsmI, ApaI and TaqI) were detected by PCR-RFLP...

Infertility is a worldwide problem affecting about 15% of couples trying to conceive. Asthenozoospermia (AZS) is one of the major causes of male infertility, diagnosed by reduced sperm motility, and has no effective therapeutic treatment. To date, a few genes have been found to be associated with AZS in humans and mice, but in most of cases its molecular aetiology remains unknown. Genetic causes of AZS may include chromosomal abnormalities, specific mutations of nuclear and mitochondrial genes. However recently, epigenetic factors, altered microRNAs expression signature, and proteomics have shed light on the pathophysiological basis of AZS...

Zinc (Zn) is necessary for the normal function of the male reproductive system and spermatozoa. Although influences of zinc deficiency on impaired spermatogenesis and male infertility have been widely considered, the molecular and cellular mechanisms of these abnormalities are not well understood. General abnormalities, including hypogonadism, Leydig cells damage, deficiency of sex hormone production and impaired spermatogenesis, as well as inflammation, antioxidant depletion, sperm death and male infertility can be observed during zinc deficiency...

Does corifollitropin alfa associated with hp-HMG protocol from the beginning of ovarian stimulation perform better than high dose rFSH alone for ovarian stimulation with GnRH antagonist in poor responders? This retrospective, monocentric, case-control pilot study was conducted in 65 poor responders (Bologna criteria) undergoing 2 consecutive IVF cycles. All patients underwent a first ovarian stimulation cycle with high dose rFSH (≥300 IU/day) alone in antagonist protocol, unfortunately leading to poor ovarian response and no pregnancy...

Most people want and expect to have children but lack of awareness about the biological limits of fertility may reduce their chance of achieving their parenthood goals. We surveyed Australian university students' intentions and expectations for future parenthood, knowledge about fertility and preferred sources of fertility information. Male and female students (n = 1215) completed an anonymous 34-item online questionnaire. Fewer than 10% did not want children. Of those who wanted children, most (75%) wanted two or more...

The purpose of this study was to investigate the association between the Val16Ala superoxide dismutase manganese-dependent (SOD2) single nucleotide polymorphism (SNP) and sperm reproductive parameters in a sample of Brazilian men. A potential association between this polymorphism and some oxidative biochemical parameters as well as sperm plasma cell-free DNA (cfDNA) levels were also evaluated. The study was performed using semen samples obtained from male patients that had undergone semen analysis according to the 2010 World Health Organisation (WHO) recommendations and the Val16Ala-SOD2 SNP was genotyped by polymerase chain reaction (PCR)...

Scientists working in assisted reproduction [members of Scientists in Reproductive Technology (SIRT) Australia, and subscribers of the online forums EmbryoMail and Quartec] were invited to complete an online questionnaire on the use of human blood products in assisted reproductive technologies (ART). A total of 260 started the questionnaire, with 208 (80%) completing it. A total of 62% of respondents had worked in human ART ≥8 years and 68% had post-graduate qualifications. The majority (82%) reported using products of animal or human origin, with 75% knowing why protein was added to culture media and 41% not worried by this...

This review aims to provide an up-to-date knowledge of the psychosocial aspects of egg donation from the perspectives of the egg share donor and their recipient. It explores the motives, experiences and attitudes of egg sharers and their views towards donor anonymity and disclosure. Conclusions are made on how these findings can guide clinical practice and improve egg sharing numbers. A systematic search of peer-reviewed journals of four computerized databases was undertaken. Eleven studies were included in the review...

The purpose of this study was to determine the incidence of oocytes with severe ovoid zona pellucida (ZP), investigate the development potential of their sibling oocytes and the clinical outcomes from affected cycles. The data were collected from our medical records. Cycles having at least one oocyte with severe ovoid ZP were defined as the 'severe ovoid group', cycles having at least one oocyte with mild ovoid ZP were defined as the 'mild ovoid group', whereas cycles without oocytes with ovoid ZPs were defined as the 'control group' (n = 150 for each group)...

High endometrial receptivity in the window of implantation (WOI) is essential for successful implantation. However, a diagnostic tool with high specificity for impaired endometrial receptivity remains to be developed. We collected endometrium specimens during the WOI from patients with RIF and women who conceived after one IVF/ICSI attempt. We conducted mRNA microarray on the samples followed by relevant comparative and functional analysis. Microarray analysis revealed 357 dysregulated mRNAs between the two groups...

Infertility is a major life crisis affecting couples' psychosocial and physical health. We aimed to assess the quality of life in Turkish infertile couples. This cross-sectional survey was carried out in 127 infertile couples admitted to a University Hospital. The quality of life was measured using the fertility quality of life tool (FertiQoL) scale. Women had lower overall quality of life than men. Women and men who were married for fewer than 10 years had a significantly lower emotional score. Women who had a history of infertility treatment, men who have lived in the town or village men with primary infertility and men who have had primary education or lower, had lower scores for mind/body subscale...

DNA methylation is a biochemical process that modifies gene expression without changing the underlying DNA sequence, and this represents the molecular basis for imprinting and epigenetics. Recent reports have revealed alterations in DNA methylation profiles in the placenta of babies born from assisted reproductive technologies (ART). This supports several previous observations that suggested an increase in the prevalence of imprinting diseases following ART treatment, and also fits our observations regarding the metabolism and requirements of early human embryos...

Research shows that young people do not know much about their fertility. In the present study, we examined fertility knowledge and perceptions of a fertility educational brochure (i.e. 'A Guide to Fertility') in five focus groups with adolescents (16-18 years, n = 19) and emerging adults (21-24 years, n = 14) who were childless, not currently pregnant (or for men partner not pregnant) or trying to conceive but intending to have a child in the future. Participants (n = 33) reported having poor knowledge of a range of fertility topics and feelings of surprise, fear and concern in response to the brochure, despite perceiving benefits of the provision of fertility education and feasibility of 'A Guide to Fertility'...

Various factors have been reported to be associated with early miscarriages, including microbial infection, chemical toxicity, maternal disorders and genetic abnormalities. In the present study, a prospective cohort study was conducted to investigate whether urinary concentrations of hydroxylated polycyclic aromatic hydrocarbons (OH-PAHs) were associated with early pregnancy loss in women undergoing in vitro fertilization-embryo transfer (IVF-ET). Risk of spontaneous pregnancy loss in patients exposed to PAHs was analysed using 40 patients who had experienced early pregnancy loss compared to 40 who had normal live births...
