The main objective of our study was to study LIF and LIF-R endometrial expression during the implantation window in the various sub-groups of infertile women according to infertility cause. A prospective observational case-control study was performed from March 2013 to February 2016. Infertile women consisted of the patients' group (group 2) while fertile women were the control group (group 1). Infertile women were divided according to infertility cause in women with tubal factor (group 2a), poor ovarian reserve (group 2b), endometriosis (group 2c) and unexplained infertility (group 2d)...

OBJECTIVE: Growing evidence suggests that increased cardiovascular disease (CVD) risk is associated with female infertility caused by conditions such as polycystic ovarian disease, obesity, thyroid dysfunction, and endometriosis. The aim of this study was to evaluate whether any relationship exists between CVD and unexplained infertility. METHODS: Sixty-five women with unexplained infertility and 65 fertile controls were enrolled in the study. CVD risk markers such as low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC), triglycerides (TG), insulin resistance (defined by the homeostasis model assessment ratio), and high-sensitivity C-reactive protein (hs-CRP) were assessed...

IgA anti-β2glycoprotein I antibodies (IgA-anti-β2GPI) seems to be the most prevalent isotype in patients with Systemic Lupus Erythematosus (SLE) with a significant association to thrombotic events. Both SLE and antiphospholipid syndrome (APS) can be associated with implantation failure, fetal loss and obstetric complications. Recent reports highlight the clinical value of IgA-anti-β2GPI determination in supporting in vitro fertilization (IVF) treatment and IVF pregnancy outcomes. We report a 36-year-old female diagnosed with SLE, endometriosis and unexplained infertility...

This study aimed to determine whether follicular output rate (FORT) can predict the clinical pregnancy rate in women with unexplained infertility undergoing IVF/ICSI. This was a prospective study conducted at Dar El Teb subfertility centre in Cairo between June 2014 and July 2016. A total of 303 women with unexplained infertility, who were undergoing IVF/ICSI, were divided into three groups according to FORT tertile values. FORT was calculated as pre-ovulatory follicle count/antral follicle count × 100. There was a progressive and significant increase from the low to the high FORT groups in the clinical pregnancy rate (29...

BACKGROUND: TEX101 is a cell membrane protein exclusively expressed by testicular germ cells and shed into seminal plasma. We previously verified human TEX101 as a biomarker for the differential diagnosis of azoospermia, and developed a first-of-its-kind TEX101 ELISA. To demonstrate the clinical utility of TEX101, in this work we aimed at evaluating ELISA performance in a large population of fertile, subfertile, and infertile men. METHODS: Mass spectrometry, size-exclusion chromatography, ultracentrifugation, and immunohistochemistry were used to characterize TEX101 protein as an analyte in seminal plasma...

Complete elucidation of fertilization process at molecular level is one of the unresolved challenges in sexual reproduction studies, and understanding the molecular mechanism is crucial in overcoming difficulties in infertility and unsuccessful in vitro fertilization. Sperm-oocyte interaction is one of the most remarkable events in fertilization process, and deficiency in protein-protein interactions which mediate this interaction is a major cause of unexplained infertility. Due to detection of how the various defects of sperm-oocyte interaction can affect fertilization failure, different experimental methods have been applied...

BACKGROUND: Although leiomyomas are the most common gynecologic disorders, non-puerperal uterine inversion due to leiomyoma is considered as a rare clinical problem. This condition can occur as a complication of a large sub-mucous leiomyoma that leads to dilate cervix and protrude into vagina. The patient may have several symptoms such as heavy vaginal bleeding, pelvic pain and intermittent acute urinary retention. CASE: We presented a 32-year-old nulliparous woman with 17 years of unexplained infertility and diagnosis of a large vaginal prolapsed non-pedunculated leiomyoma...

Premature ovarian failure (POF) is a kind of gynecological disease that causes amenorrhea, infertility, menopause and urogenital symptoms. Currently hormone replacement therapy (HRT) is the most popular choice for women with POF to get rid of menopausal syndrome. However, as the popularization of Chinese herbs made Chinese medicine (CM) shine new lights, physicians are able to treat POF with both meno-herbs and integrated therapy. HRT has its own indications and contraindications. For example, unexplained vaginal bleeding, acute liver damage, liver dysfunction, vascular embolization, and breast cancer are all contraindications of HRT, and CM is taken by more physicians as an adjuvant therapy...

BACKGROUND: Chronic endometritis (CE) is a continuous inflammation of uterine endometrium, and it is usually symptomless. As CE has been thought not to affect the reproductive status and general health of affected women, its significance has not been explored. However, recent studies have shown that CE is related with repeated implantation failures after in vitro fertilization-embryo transfer, unexplained infertility, and recurrent miscarriages. As decidua differentiates to support the implantation process and maintains the pregnancy, we hypothesized that CE may influence the process of decidualization...

Poor uterine receptivity leads to implantation defects or failure. Identification of uterine molecules crucial to uterine receptivity and/or embryo implantation provides the opportunity to design a diagnostic screening toolkit for uterine receptivity or targeted drug discovery for treating implantation-based infertility. In this regard, gene-profiling studies performed in humans and rodents have identified numerous genes involved in the transcriptional regulation of uterine receptivity and embryo implantation...

The androgen receptor (AR) plays a crucial role in normal physiology, development and metabolism as well as in the aetiology and treatment of diverse pathologies such as androgen insensitivity syndromes (AIS), male infertility and prostate cancer (PCa). Here we show that dimerization of AR ligand-binding domain (LBD) is induced by receptor agonists but not by antagonists. The 2.15-Å crystal structure of homodimeric, agonist- and coactivator peptide-bound AR-LBD unveils a 1,000-Å(2) large dimerization surface, which harbours over 40 previously unexplained AIS- and PCa-associated point mutations...

Insulin resistance and compensatory hyperinsulinemia are characteristic features of obesity and polycystic ovary syndrome, and both are associated with reduced fertility and implantation. There is little knowledge about the effect of insulin on the decidualization process and previous findings are contradictory. We investigated the effect of insulin on the regulation of forkhead box protein O1 (FOXO1), one of the most important transcription factors during decidualization. Endometrial stromal cells were isolated from six healthy, regularly menstruating women and decidualized in vitro...

Multi-foetal gestation is a well-known, adverse outcome of infertility treatment. Maternal and obstetrical complications are more frequent in multiple pregnancies compared to singletons. The aim of this study was to determine parameters that affect the risk for multiple pregnancies after ovarian stimulation (OS) with intrauterine insemination (IUI). We retrospectively evaluated all cases of OS with IUI cycles that ended with successful clinical pregnancy. A total of 259 pregnancies were analysed (175 singletons, 63 twins and 21 triplets)...
