REVIEW
Youssef Mouhayar, Ophelia Yin, Sunni L Mumford, James H Segars
The cost of fertility treatment is expensive and interventions that reduce cost can lead to greater efficiency and fewer embryos transferred. Endometrial polyps contribute to infertility and are frequently removed prior to infertility treatment. It is unclear whether polypectomy reduces fertility treatment cost and if so, the magnitude of cost reduction afforded by the procedure. The aim of this study was to determine whether performing office or operative hysteroscopic polypectomy prior to infertility treatment would be cost-effective...

Sex-determining region Y is a crucial gene that initiates male sex determination in mammals. Mutations of the Sp1-binding site in the 5' flanking region of SRY are associated with clinical male-to-female sex reversal syndrome, although such occurrences are rare and, until now, have not been reported in animal models. In this study, we mutated Sp1-binding sites in the 5' flanking region of the rabbit SRY gene using the CRISPR/Cas9 system. As expected, the SRY-Sp1 knockout rabbits had female external and internal genitalia and exhibited normal female copulatory behaviors, but they were infertile, and the adults displayed reduced follicles...

The origin of infertility in the hyperplasic ovary of ex-fissiparous planarians remains poorly understood. In a previous study we demonstrated that a complex process of early autophagy, followed by apoptotic processes, occurs in the hyperplasic ovary of the freshwater planarian Dugesia arabica. The present study aimed to investigate whether the mRNA expression levels of selected mRNA-like genes are altered in the hyperplasic ovary of the ex-fissiparous freshwater planarian D. arabica compared to the normal ovary...

PURPOSE: A retrospective cohort study was conducted to evaluate and compare the prevalence of congenital anomalies in babies and fetuses conceived after four procedures of assisted reproduction technologies (ART). METHODS: The prevalence of congenital anomalies was compared retrospectively between 2750 babies and fetuses conceived between 2001 and 2014 in vitro fertilization with standard insemination (IVF), IVF with intracytoplasmic sperm injection (ICSI), IVF with frozen embryo transfer (FET-IVF), and ICSI with frozen embryo transfer (FET-ICSI)...

The phosphoinositide 3-kinase/AKT signaling pathway negatively regulates follicle activation via the forkhead box O (FOXO) transcription factor in rodents. FOXO3 knockout mice exhibit global activation of primordial follicles leading to early depletion of ovarian follicles and subsequent infertility. Whether a similar mechanism for follicle activation exists in the primate ovary is unclear. In the current study, protein localization of FOXO1, 3 and 4 as well as their upstream regulator, AKT/p-AKT, were examined in rhesus macaque ovaries of 3 developmental stages: fetal, prepubertal and adult...

BACKGROUND: Several markers were studied previously in order to predict the pregnancy outcome of assisted reproductive techniques, however serum beta human chorionic gonadotropin (β-hCG) was found to be the most predictive marker. AIMS: The primary aim of this study was to evaluate the value of serum β-hCG levels in discriminating biochemical and clinical pregnancies 12 days after embryo transfer (ET) and to determine the factors predicting of ongoing pregnancy was established as the secondary aim...

This paper presents data associated with the research article entitled "Targeted downregulation of s36 protein unearths its cardinal role in chorion biogenesis and architecture during Drosophila melanogaster oogenesis" [1]. Drosophila chorion is produced by epithelial follicle cells and one of its functional serving role is egg fertilization through the micropyle, a specialized narrow channel at the anterior tip of the egg [2]. Sperm entry during fertilization is necessary for the egg to complete meiosis [3]...

Ovarian hyperstimulation syndrome (OHSS) following gonadotropin-releasing hormone agonist (GnRH-a) trigger is rare. Here, we report a case of severe OHSS after combined GnRH-a and low-dose human chorionic gonadotropin (hCG) trigger in a patient with a single kidney. The patient is a 32-year-old women with a two-year history of infertility. The patient's history was significant for a single kidney, that is, she had donated a kidney to a family member three years ago. The patient underwent controlled ovarian stimulation (COS) for in vitro fertilization (IVF) and received a combined 2 mg GnRH-a and 1500 IU hCG ovulatory trigger...

PROBLEM: Elucidating immune mechanisms in the endometrium, which lead to the success of implantation and pregnancy, is important in reproductive medicine. Studies of immune cell abundance have shown conflicting results, and the expression and importance of HLA class Ib proteins in pre-implantation endometrium have not yet been investigated. METHOD OF STUDY: The study population consisted of four subgroups: a hydrosalpinx, a salpingectomy, an unexplained infertility, and a fertile control group...

Werner Syndrome (WS) is a rare, adult‑onset progeroid syndrome that is associated with multiple age‑associated complications and relatively short life expectancy. The characteristics of WS include a 'bird‑like' appearance, canities, cataracts and ulcerations around the ankles. In addition, certain patients develop hypogonadism with atrophic genitalia and infertility. The average life span of affected individuals is 54 years. Previous studies have demonstrated that mutations in the Werner syndrome RecQ like helicase gene (WRN) may contribute to WS...

Spermatozoa retrieved from the testis of men with high levels of sperm DNA fragmentation (SDF) in the neat semen tend to have better DNA quality. Given the negative impact of SDF on the outcomes of Assisted Reproductive Technology (ART), an increased interest has emerged about the use of testicular sperm for intracytoplasmic sperm injection (Testi-ICSI). In this article, we used a SWOT (strengths, weaknesses, opportunities, and threats) analysis to summarize the advantages and drawbacks of this intervention...

OBJECTIVE: To evaluate whether there is a synergistic effect of varicocele and smoking status on semen parameters. METHODS: A retrospective evaluation of 715 men attending an infertility clinic between 2001 and 2009 was carried out. The presence of a varicocele was determined by clinical examination and cigarette smoking habits were documented allowing patients to be divided into 4 groups: non-smokers (n = 369), mild smokers (n = 186, 1-10 cigarettes/day), moderate smokers (n = 129, 10-20 cigarettes/day) and heavy smokers (n = 31, over 20 cigarettes/day)...

Male infertility is a devastating problem that affects many couples worldwide. However, the molecular mechanisms and causes of idiopathic male infertility remain unclear. Circulating cell-free nucleic acids have an important role in human physiology and emerging evidence suggests that they play a role in male infertility. This review summarizes recent results on cell-free and intracellular nucleic acids in male infertility and discusses their potential use as biomarkers of male infertility in the clinical practice...

Many genetic alterations have been identified to aid in understanding the genetic basis of male infertility, however, the cause of 30% of male infertility remains unknown. Some studies indicated that subdeletions of Y chromosome may be a reason for male infertility caused by testicular failure. In this regard, we aimed to investigate frequency of AZFc region subdeletions and their clinical effects in patients with idiopathic infertility. A total of 333 male infertile patients with non-obstructive azoospermia (NOA) or oligoasthenoteratozoospermia (OAT), and 87 normozoospermic controls were screened to detect gr/gr, b1/b3 and b2/b3 subdeletions...

Exogenous administration of superovulatory hormones negatively affects oocyte competence in mammals. Phosphodiesterase 3A inhibitors were found to improve competence of oocytes matured in vitro in several species, including humans. This study was therefore designed to define oocyte maturation synchronization and competence in superovulated mice treated with cilostazol, a selective phosphodiesterase 3A inhibitor. Swiss Webster mice were superovulated and treated orally with 7.5mg cilostazol once or twice to result in ovulation of immature oocytes at the metaphase I (MI) or germinal vesicle (GV) stage, respectively...
