The present study examined how infertile Iranian clients confront infertility. Research on infertility has confirmed the significance of a socio-cultural context in the formation of responses to infertility. This study used the grounded theory approach to explore the experiences of infertile individuals presenting at the Royan Institute in Iran from October 2013 to September 2014. Clients with infertility of at least two years in duration were recruited using purposive sampling followed by theoretical sampling...

Female infertility is a worldwide medical problem, and the scarcity of infertility biomarkers has hindered the ability to launch preventive and therapeutic measures in a timely manner. Intriguingly, alterations in endocannabinoids (eCBs) and N-acylethanolamides (NAEs) have been observed in the biofluids of infertile females. Therefore, a hypothesis of using eCB and NAEs in biofluids as infertility biomarkers was proposed by several researchers; however, little evidence exists to verify the hypothesis. To investigate their correlations with female infertility, we developed a magnetic liquid microextraction-chemical derivatization (MLME-CD) method coupled with liquid chromatography-tandem mass spectrometry for the quantification of eCBs and NAEs in biofluids...

In a 1989 paper (Am J Epidemiol. 1989;130(2):259-67), Marchbanks et al. noted inconsistent definitions of infertility across research and clinical practice and examined differences in prevalence estimates across definitions. Since their study, there have been substantial changes in society, technology, and clinical practice related to female reproductive health. In response, we revisited the original paper using data from a recent study among reproductive-aged women. Internal comparisons across various definitions of infertility were made by assessing how many and which women were classified as infertile, their age at infertility, and probability of spontaneous pregnancy after infertility; results were also compared with Marchbanks et al...

The use of intra-cytoplasmic sperm injection (ICSI) has increased significantly worldwide, often chosen instead of in vitro fertilization (IVF), yet long-term health outcomes are unknown and health differences between ICSI and IVF conceptions have not been comprehensively assessed. A systematic review of health outcomes of ICSI-conceived offspring beyond the neonatal period compared to IVF-conceived offspring was carried out. PubMed, OVID Medline/Embase, Informit, Web of Science and Proquest databases were searched on 9 November 2016 for studies reporting on health outcomes in ICSI-conceived offspring beyond 28 days after birth...

Male infertility is most commonly caused by spermatogenetic failure, clinically noted as oligo- or azoospermia. Today, in approximately 20% of azoospermic patients, a causal genetic defect can be identified. The most frequent genetic causes of azoospermia (or severe oligozoospermia) are Klinefelter syndrome (47,XXY), structural chromosomal abnormalities and Y-chromosomal microdeletions. Consistently with Ohno's law, the human X chromosome is the most stable of all the chromosomes, but contrary to Ohno's law, the X chromosome is loaded with regions of acquired, rapidly evolving genes, which are of special interest because they are predominantly expressed in the testis...

This paper aimed to describe the basic aspects of uterine transplant (UTx) research in humans, including preliminary experiences in rodents and domestic species. Studies in rats, domestic species, and non-human primates validated and optimized the UTx procedure in terms of its surgical aspects, immunosuppression, rejection diagnosis, peculiarities of pregnancy in immunosuppressed patients, and patients with special uterine conditions. In animal species, the first live birth from UTx was achieved in a syngeneic mouse model in 2003...

Asthenoszoopermia, characterized by reduced sperm motility, is one of the primary forms of male infertility. Whereas most cases were diagnosed into unexplained asthenozoospermia (UA) because the etiology cannot be identified. In animal models, epigenetic dysregulation in epididymis can impair sperm maturation and result in asthenozoospermia. However, researches of epididymal epigenetic regulation on humans are impeded by the difficulty in obtaining epididymal tissues. We previously identified cell-free seminal microRNAs predominately derived from epididymis in human ejaculate...

STUDY QUESTION: What is the effectiveness of a multifaceted implementation strategy compared to usual care on improving the adherence to guideline recommendations on expectant management for couples with unexplained infertility? SUMMARY ANSWER: The multifaceted implementation strategy did not significantly increase adherence to guideline recommendations on expectant management compared to care as usual. WHAT IS KNOWN ALREADY: Intrauterine insemination (IUI) with or without ovarian hyperstimulation has no beneficial effect compared to no treatment for 6 months after the fertility work-up for couples with unexplained infertility and a good prognosis of natural conception...

Saima Rafique, Alan H Decherney
Endometriosis is a chronic medical condition that affects around 6% to 10% of reproductive age women. Pelvic pain, dysmenorrhea, and infertility are the most common presenting symptoms. The disease is characterized by estrogen-dependent growth of the endometrial glands and stroma outside the endometrial cavity. The diagnosis requires a high degree of suspicion and can be only confirmed on histopathology. Treatment includes medical and surgical options. Both hormonal and nonhormonal medical options are available and are tried at first with a goal to control pain and stop the growth of the endometriotic lesions...

PURPOSE OF REVIEW: The negative impact of postoperative adhesions has long been recognized, but available options for prevention remain limited. Minimally invasive surgery is associated with decreased adhesion formation due to meticulous dissection with gentile tissue handling, improved hemostasis, and limiting exposure to reactive foreign material; however, there is conflicting evidence on the clinical significance of adhesion-related disease when compared to open surgery. Laparoscopic surgery does not guarantee the prevention of adhesions because longer operative times and high insufflation pressure can promote adhesion formation...

The socio-demographic and clinical characteristics of 246 consecutive couples seeking assisted conception in a university teaching hospital in Nigeria from inception in 2011 till 2014 were reviewed restrospectively. Eighty-five (34.5%) were in the 35-40 years age group. The body mass index of the women showed that 111 (45.1%) were overweight. One hundred and ninety five (88%) were referred on account of secondary infertility. The mean duration of infertility was 9.6 ± 4.8 years. Major factors identified were male factor 128 (52%), ovarian/age-related decline in fertility 107 (43...

Disorders/Differences of Sex Development (DSD), as defined by the 2006 Consensus Statement, are "congenital conditions in which development of chromosomal, gonadal, or anatomic sex is atypical." They represent a spectrum of chronic medical conditions collectively affecting about 1% of the population and are associated with increased risk of infertility, cancer, and psychosocial distress. Clinical management in DSD is subject to multiple controversies about gender assignment, the timing and appropriateness of genital surgery and the approach to disclosure...

STUDY QUESTION: Does ICSI induce specific DNA methylation changes in the resulting offspring? SUMMARY ANSWER: Although several thousand analyzed CpG sites (throughout the genome) displayed significant between-group methylation differences, both ICSI and spontaneously conceived children varied within the normal range of methylation variation. WHAT IS KNOWN ALREADY: Children conceived by ART have increased risks for medical problems at birth and to the extent of present knowledge also in later life (i...

Postoperative adhesions are pathological attachments that develop between abdominopelvic structures following surgery. Considered unavoidable and ubiquitous, postoperative adhesions lead to bowel obstructions, infertility, pain, and reoperations. As such, they represent a substantial health care challenge. Despite over a century of research, no preventive treatment exists. We hypothesized that postoperative adhesions develop from a lack of movement of the abdominopelvic organs in the immediate postoperative period while rendered immobile by surgery and opiates, and tested whether manual therapy would prevent their development...

REVIEW
Margit Dueholm
This review includes an analysis of the clinical studies evaluating reproductive outcome and adenomyosis, and a review of studies on reproductive outcome and surgical treatment options for adenomyosis. Strict diagnostic criteria and classification of disease are needed for an image diagnosis of adenomyosis. Studies of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) populations and women with surgically treated deep endometriosis have suggested that adenomyosis has a negative impact on reproductive outcome, although there are substantial variations between studies...

The mammalian ovarian follicle is the complex reproductive unit comprising germ cell, somatic cells (Cumulus and Granulosa cells), and follicular fluid (FF): paracrine communication among the different cell types through FF ensures the development of a mature oocyte ready for fertilization. This paper is focused on non-coding RNAs in ovarian follicles and their predicted role in the pathways involved in oocyte growth and maturation. We determined the expression profiles of microRNAs in human oocytes and FF by high-throughput analysis and identified 267 microRNAs in FF and 176 in oocytes...

Regucalcin (RGN) is a calcium-regulating, anti-apoptotic, antioxidative and antiproliferative multifunctional protein predominantly seen in liver and kidney. All these functions are very crucial during spermatogenesis and sperm maturation process until fertilization of the ovum. Although many studies have reported the wide distribution of regucalcin in the male reproductive tract of the rat, human and bovine, its presence in spermatozoa is yet to be demonstrated wherein calcium has a pivotal role in the transport, capacitation, acrosomal reaction and further fusion with ova...

Semen parameters are variable within-man but it is unclear whether one sample could represent a man's long-term average in epidemiologic studies. Between 2005 and 2014, 329 men from a fertility clinic provided 768 semen samples in the EARTH study in Boston, Massachusetts.Total sperm count, concentration, morphology, motility, and ejaculate volume were assessed. We used linear mixed models to compare men's first samples to their long-term averages, and calculate intraclass correlation coefficients for each parameter...
