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...

This is a rare case of serpine gene polymorphism causing thrombophilia and recurrent implantation failure following intrauterine insemination. SERPINE1 gene encodes plasminogen activator inhibitor type 1 and inhibits fibrinolysis, or clot dissolution. The 4G variant results in increased expression of SERPINE1 and consequently higher inhibition of fibrinolysis, thus leading to thrombophilia. The patient had unexplained primary infertility for 9 years. Ovulation induction was done with gonadotropin releasing hormone (GnRH) agonist long protocol...

This prospective case-control study aimed to test the presence of insulin resistance (IR) in men with unexplained infertility. We included two groups: the study group including 160 infertile men with unexplained oligozoospermia (sperm count <10 × 10(6)/ml) and normal hormonal profile, and the control group of 79 men with proven fertility within the preceding year. A fasting blood test measured IR, FSH, LH, total cholesterol, low-density lipoprotein, high-density lipoprotein and triglycerides. Insulin level was significantly higher in the study group (13...

BACKGROUND: While screening of thyroid peroxidase antibody (TPOAb) has been recommended in women with primary ovarian insufficiency, the relationship between thyroid autoimmunity (TAI) and ovarian reserve remains undetermined. Because the TAI prevalence was reported to be different between different ethnic/racial groups, this study aimed to investigate the TAI prevalence in Chinese women with variable ovarian reserve. METHODS: This is a cross-sectional study conducted in a university infertility clinic between October 2013 and March 2016...

Congenital bilateral absence of the vas deferens (CBAVD) is an important cause of obstructive azoospermia and male infertility worldwide. Cystic fibrosis transmembrane conductance regulator (CFTR) mutations are the main pathogenic cause, although a proportion of cases are still unexplained. Recently, adhesion G protein-coupled receptor G2 (ADGRG2) gene, a novel pathogenic gene for CBAVD was identified. We did a single population replication study in Chinese CBAVD patients to replicate its role in CBAVD developing...

We used a gas chromatography-mass spectrometry (GC-MS) based metabolomics approach to obtain the metabolic profiling of unexplained male infertility (UMI), and identified seminal plasma biomarkers associated with UMI by a two-stage population study. A robust OPLS-DA model based on these identified metabolites was able to distinguish 82% of the UMI patients from health controls with a specificity of 92%. In this model, 44 metabolites were found differentially expressed in UMI subjects compared with health controls...

BACKGROUND: The relationship between intramural myomas and fertility remains unclear. The main debate rests on whether cavity-distorting intramural myomas (CDMs) adversely affect fertility more than non-CDMs. We aimed to compare the effects of enucleating non-CDMs and CDMs on fertility improvement in females with unexplained infertility. METHODS: We prospectively recruited 83 women undergoing myomectomy for unexplained infertility with intramural myomas between June 2008 and November 2012 and classified them into non-CDMs group (n = 45) and CDMs group (n = 38)...

PURPOSE: This study aims to introduce a new tool (the Follicular Sensitivity Index; FSI) for objective assessment of follicular responsiveness to exogenous gonadotropins and to evaluate its ability to predict the clinical pregnancy rate in women with unexplained infertility or tubal factor undergoing IVF/ICSI. METHODS: FSI was calculated as preovulatory follicle count (PFC) × 100,000/[antral follicle count (AFC) × total received FSH doses]. One thousand women were included and were divided according to the FSI tertile values into three groups...

Abnormal vaginal microbiota (AVM) or bacterial vaginosis (BV) might negatively impact reproductive outcomes of in vitro fertilization (IVF). However, before randomized controlled trials are initiated to investigate cause and effect, it is necessary to establish the optimal treatment for AVM. Metronidazole seems ineffective to treat the biofilm in AVM; thus, clindamycin could be suggested as a relevant antibiotic agent for future intervention based studies. In the present case report, we present the first longitudinal follow-up of the vaginal microbiota with molecular methods during and after oral clindamycin treatment...

Two unrelated men complaining of primary male infertility presented to Orient Hospital in Damascus city. Physical examination showed moderate hypoandrogenic features. Both men were azoospermic. Hormone profiles revealed an elevation of follicle-stimulating hormone in one patient, but all the other hormones tested were within normal limits for both patients. Further genetic analyses, including karyotype and microdeletions in the AZF region of the Y chromosome, were normal in both patients. Mild androgen insensitivity syndrome was expected in the two patients...

The current definition of infertility acknowledges the importance of duration of pregnancy seeking but fails to recognize the prevalent negative impact of female age. In fact, the diagnosis of unexplained infertility increases with women's age because of our incapacity to discern between age-related infertility and real unexplained infertility. Physicians' response to the pressures of increased female age has been to take prompt refuge in assisted reproduction despite the lack of robust evidence and the inherent risks and costs of these procedures...

BACKGROUND: The purpose of this retrospective observational study was to identify prognostic factors that lead to a live birth (LB) in couples with unexplained infertility in order to define the best ART strategy. METHODS: Prognostic factors of couples with unexplained infertility managed initially with gonadotropin intrauterine inseminations (IUI) at a single university fertility center were analyzed. Infertility was not considered "unexplained" in case of mild male infertility and suspicion of diminished ovarian reserve (FSH>10IU/L)...
