OBJECTIVES: To present the first pregnancy achieved in Turkey with frozen-warmed oocytes in a case with previous nine unsuccessful assisted reproductive technology (ART) attempts. METHODS: The clinical follow-up of a 33-year-old female applying to our ART centre after a long and complicated history of infertility is described. RESULTS: In April 2013, the woman attempted our centre for her 10th ART trial. She informed us on oocyte pick-up (OPU) day that her husband had been hospitalized following a car crush in Albania and was unable to travel to our clinic to give a sperm sample...

MicroRNAs (miRNAs) are negative modulators of gene expression that fine-tune numerous biological processes. miRNA loss-of-function rarely results in highly penetrant phenotypes, but rather, influences cellular responses to physiologic and pathophysiologic stresses. Here, we have reported that a single member of the evolutionarily conserved miR-7 family, miR-7a2, is essential for normal pituitary development and hypothalamic-pituitary-gonadal (HPG) function in adulthood. Genetic deletion of mir-7a2 causes infertility, with low levels of gonadotropic and sex steroid hormones, small testes or ovaries, impaired spermatogenesis, and lack of ovulation in male and female mice, respectively...

INTRODUCTION: Anti-Mullerian Hormone (AMH) is a useful endocrine marker for assessing the ovarian reserve. AMH serum level reflects the number of follicles that have made the transition from the primordial pool into the growing follicle pool, and it is not controlled by gonadotropins. AIM: The present study was conducted to correlate serum AMH levels with Polycystic Ovarian Syndrome (PCOS) and type of treatment protocol. MATERIALS AND METHODS: Serum AMH levels were performed in the early follicular phase (on 2(nd) day of menstrual cycle) both in infertile females including PCOS and control women...

BACKGROUND: Mutational combinations of the cystic fibrosis transmembrane conductance regulator, CFTR, gene have different phenotypic manifestations at the molecular level with varying clinical consequences for individuals possessing such mutations. Reporting cystic fibrosis transmembrane conductance regulator mutations is important in understanding the genotype-phenotype correlations and associated clinical presentations in patients with cystic fibrosis. Understanding the effects of mutations is critical in developing appropriate treatments for individuals affected with cystic fibrosis, non-classic cystic fibrosis, or cystic fibrosis transmembrane conductance regulator-related disorders...

The aim of the study was to evaluate reproductive outcomes in a cohort of infertile couples with severe and complete asthenozoospermia undergoing TESA (testicular sperm aspiration) with ICSI. We conducted a retrospective study of 28 couples with complete or severe asthenozoospermia who underwent TESA between January 2010 and December 2015. We compared TESA-ICSI outcomes of these couples to ejaculate ICSI outcomes of 40 couples with severe asthenozoospermia treated during the same time period at our institution...

BACKGROUND: Reciprocal Y autosome translocations are rare but frequently associated with male infertility. We report on the meiotic outcome in embryos fathered by two males with the karyotypes 46,X,t(Y;4)(q12;p15.32) and 46,X,t(Y;16)(q12;q13). The two couples underwent preimplantation genetic diagnosis (PGD) enabling determination of the segregation types that were compatible with fertilization and preimplantation embryo development. Both PGD and follow up analysis were carried out via fluorescence in situ hybridization (FISH) or array comparative genomic hybridization (aCGH) allowing the meiotic segregation types to be determined in a total of 27 embryos...

OBJECTIVE: Cushing's syndrome (CS) affects all age groups, but epidemiologic data in young pa-tients are very limited. We therefore examined the incidence, prevalence, and hospital morbidity of CS in children and adolescents. DESIGN: In a nationwide cohort study we included all Danish citizens aged 0-20 years from 1977 to 2012. Data were obtained from the Danish National Patient Registry using the International Classi-fication of Diseases (ICD) codes and the Danish Civil Registration System...

BACKGROUND: The prevalence of several human morbid phenotypes is sometimes much higher than intuitively expected. This can directly arise from the presence of two sexes, male and female, in one species. Men and women have almost identical genomes but are distinctly dimorphic, with dissimilar disease susceptibilities. Sexually dimorphic traits mainly result from differential expression of genes present in both sexes. Such genes can be subject to different, and even opposing, selection constraints in the two sexes...

BACKGROUND: Cervical cancer is the second most commonly diagnosed cancer in females and is a leading cause of cancer-related mortality in Kenya; limited cervical cancer screening services may be a factor. Few studies have examined men's and women's perceptions on environmental and psychosocial barriers and benefits related to screening. MATERIALS AND METHODS: In 2014, 60 women aged 25-49 years and 40 male partners participated in 10 focus groups (6 female and 4 male), in both rural and urban settings (Nairobi and Nyanza, Kenya), to explore perceptions about barriers to and benefits of cervical cancer screening...

There are variant rates of oocyte degeneration after intracytoplasmic sperm injection (ICSI) among different patients. Oocyte degeneration after ICSI may reflect the cohort of oocyte quality and subsequent embryo development capacity and clinical outcome. This retrospective study analyzed 255 cycles with at least one degenerated oocyte after ICSI (degeneration group) and 243 cycles with no degenerated oocytes after ICSI (control group). Basic characteristics like female age, body mass index, duration of infertility, hormone (FSH, LH, E2) levels on day 3 of menses, and primary infertility patient rate were similar between the two groups (p > 0...

Asherman syndrome (intrauterine adhesion) is often associated with menstrual abnormalities, infertility and recurrent miscarriage in female. Currently the molecular mechanism regulating the pathogenesis of Asherman syndrome is not known. Here we revealed that the inflammatory factor NF-κB expression is significantly elevated in the endometrial samples of Asherman syndrome patients. To further study the molecular mechanisms, we established an Asherman syndrome rat model and confirmed the important role of NF-κB in the pathogenesis of Asherman syndrome...

Prolactinomas account for ∼40% of all pituitary adenomas and are important causes of infertility and gonadal dysfunction. In general, most prolactinomas are treated medically with dopaminergic agonists, while surgery is reserved for patients intolerant or nonresponsive to these medications. The aim of this study was to carry out a comparative analysis of the cost-effectiveness of medical therapy with bromocriptine and surgical therapy with trans-sphenoidal surgery. A Markov model was developed based on retrospective data from 126 patients with prolactinoma treated in our hospital between October 2008 and May 2009, and from data published previously...

Somatic X dosage compensation requires two mechanisms: X inactivation balances X gene output between males (XY) and females (XX), while X upregulation, hypothesized by Ohno and documented in vivo, balances X gene with autosomal gene output. Whether X dosage compensation occurs in germ cells is unclear. We show that mouse and human germ cells exhibit non-canonical X dosage states that differ from the soma and between the sexes. Prior to genome-wide reprogramming, X upregulation is present, consistent with Ohno's hypothesis...

Endometriosis is a common female reproductive disease characterized by invasion of endometrial cells into other organs, frequently causing pelvic pain and infertility. Alterations of the vitamin D system have been linked to endometriosis incidence and severity. To shed light on the potential mechanism for these associations, we examined the effects of 1,25(OH)2D3 on gene expression in endometriosis cells. Stromal cell lines derived from endometriosis tissue were treated with 1,25(OH)2D3, and RNA-seq was used to identify genes differentially expressed between treated and untreated cells...

Pelvic inflammatory disease (PID) is a clinical syndrome of the female reproductive tract characterized by inflammation of the endometrium, fallopian tubes, or peritoneum (1). PID occurs when microorganisms ascend from the vagina or cervix to the fallopian tubes and other upper genital tract structures (1). PID can result from untreated bacterial infections, including chlamydia and gonorrhea, and can lead to infertility, ectopic pregnancy, and chronic pelvic pain (1). Because there is no single diagnostic test for PID, clinicians rely on nonspecific signs and symptoms for diagnosis...

It has been suggested that future application of stem-cell derived gametes (SCD-gametes) might lead to the possibility for same-sex couples to have genetically related children. Still, for this to become possible, the technique of gamete derivation and techniques of reprogramming somatic cells to a pluripotent state (directly or via somatic cell nuclear transfer) would have to be perfected. Moreover, egg cells would have to be derived from male cells and sperm cells from female cells, which is believed to be particularly difficult, if not impossible...

STUDY QUESTION: Does a breast cancer diagnosis impact ovarian function in the setting of fertility preservation? SUMMARY ANSWER: Ovarian reserve and ovarian stimulation outcomes are similar in patients with a new diagnosis of breast cancer and patients undergoing elective fertility preservation. WHAT IS KNOWN ALREADY: Prior studies, with small study populations, lack of controlling for individual differences in ovarian reserve and infertile controls, have reported conflicting outcomes for cancer patients undergoing ovarian stimulation for fertility preservation...
