The aim of this study was to compare the outcome of intracytoplasmic sperm injection (ICSI) and embryo transfer between couples with infertility due to male non-obstructive azoospermia (NOA) and obstructive azoospermia (OA). A retrospective analysis of 234 couples with azoospermia who were treated by ICSI and embryo transfer between January 2007 and October 2010 was performed. There were 61 couples in NOA group and 173 couples in OA group. Fertilization rates, pregnancy and clinical pregnancy rates were the main outcome measures...

Sperm-mediated gene transfer (SMGT) is based on the capacity of sperm to bind exogenous DNA and transfer it into the oocyte during fertilization. In bovines, the progress of this technology has been slow due to the poor reproducibility and efficiency of the production of transgenic embryos. The aim of the present study was to evaluate the effects of different sperm transfection systems on the quality and functional parameters of sperm. Additionally, the ability of sperm to bind and incorporate exogenous DNA was assessed...

BACKGROUND: Implantation is one of the essential steps for the success of assisted reproductive techniques (ART). Their success depends on three main factors: embryo quality, endometrial receptivity (ER), and synchrony between embryo and endometrium. There are various factors that regulate the complex process of implantation. In this regard, one may refer to human chorionic gonadotropin (hCG) as the most important factor. OBJECTIVE: This study aims to investigate the effect of intrauterine hCG injection before embryo transfer (ET) on pregnancy outcome in infertile couples...

Objective: To evaluate the potential efficacy and safety of gonadotropin-releasing hormone agonist(GnRH-a) administration in the luteal-phase on in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles in assisted reproductive technology (ART). Methods: The relevant papers published before November 2015 were electronically searched in PubMed, EMBASE, Cochrane Library, WHO ICTRP, ClinicalTrials.gov, CNKI, CBM and WanFang database to collect randomized controlled trial (RCT) involving GnRH-a administration in the luteal-phase on IVF/ICSI cycles in ART...

A cross-sectional study was carried out at the Australian Concept Infertility Medical Centre from June 2014 to June 2015 to relate serum kisspeptin levels on human chorionic gonadotrophin (HCG) day with pregnancy outcome after intracytoplasmic sperm injection (ICSI). A total of 176 women aged 20 to 42 years, with regular menstrual cycles, normal thyroid function and prolactin levels selected for ICSI were included in the study. Patients with uterine fibroids, metabolic disorders, short agonist and antagonist protocol were excluded...

AIM: The aim of this study was to assess the predictive value of serum substance P (SP) concentrations on oocyte maturation and clinical pregnancy. METHODS: Ninety-three women with unexplained infertility underwent intracytoplasmic sperm injection (ICSI) cycles. Antagonist protocol was started for each participant and at the day of oocyte pick up, serum samples were obtained from each participant to assess SP concentrations, and these concentrations were utilized to predict mature/total oocyte ratio and clinical pregnancy...

PURPOSE: The worldwide prevalence of adverse pregnancy outcomes (APOs) in singleton pregnancies after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) is suggested to vary; however, a complete overview is missing. The aim of this review is to estimate the worldwide prevalence of APOs associated with IVF/ICSI singleton pregnancies. METHODS: PubMed, Google Scholar, Cochrane Libraries, and Chinese databases were searched for studies assessing APOs among IVF/ICSI singleton births through March 2016...

BACKGROUND: Cryptozoospermia (CO) is a situation in which spermatozoa cannot be observed in a fresh semen sample unless an extended centrifugation and microscopic search are performed. CO patients are suggested to use only intracytoplasmic sperm injection (ICSI) as infertility treatment. But still there is debate about the choice of sperm source in cryptozoospermic men candidate for ICSI. OBJECTIVES: This study was conducted to evaluate fertility outcomes in men with idiopathic cryptozoospermia who were treated using ICSI with freshly ejaculated sperm and testis sperm extraction (TESE) or percutaneous epididymal sperm aspiration (PESA)...

Mutations in the ataxia-telangiectasia (A-T)-mutated (ATM) gene give rise to the human genetic disorder A-T, characterized by immunodeficiency, cancer predisposition, and neurodegeneration. Whereas a series of animal models recapitulate much of the A-T phenotype, they fail to present with ataxia or neurodegeneration. We describe here the generation of an Atm missense mutant [amino acid change of leucine (L) to proline (P) at position 2262 (L2262P)] rat by intracytoplasmic injection (ICSI) of mutant sperm into oocytes...

OBJECTIVE: To compare the clinical outcomes of intracytoplasmic sperm injection (ICSI) between spermatozoa retrieved from testicular biopsy and from ejaculate in cryptozoospermia patients. METHODS: The clinical data of 285 cryptozoospermia patients, who underwent ICSI treatment in our center during the period from March 2009 to November 2013, were retrospectively analyzed. Within them, ejaculated sperms were used in 214 cases (group 1) and testicular sperms extracted by testicular sperm aspiration (TESA) or conventional testis dissection sperm extraction (TESE) were used in 71 cases (group 2)...

OBJECTIVES: Fertility services in the UK are offered by over 200 Human Fertilisation and Embryology Authority (HFEA)-registered NHS and private clinics. While in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) form part of the National Institute for Health and Care Excellence (NICE) guidance, many further interventions are offered. We aimed to record claims of benefit for interventions offered by fertility centres via information on the centres' websites and record what evidence was cited for these claims...

OBJECTIVES: To evaluate treatment results of electroejaculation in patients with spinal cord injuries and the additional value of repeated electroejaculation. METHODS: We carried out a retrospective chart analysis of all spinal cord injury patients treated with electroejaculation at University Medical Center Utrecht, Utrecht, the Netherlands, from January 1994 to January 2015.

Cloned mice derived from somatic or ES cells show placental overgrowth (placentomegaly) at term. We had previously analyzed cloned and normal mouse placentae by using two-dimensional gel electrophoresis and mass spectrometry to identify differential protein expression patterns. Cloned placentae showed upregulation of tissue inhibitor of metalloproteinase-2 (TIMP-2), which is involved in extracellular matrix degradation and tissue remodeling, and downregulation of pre-B cell colony enhancing factor 1 (PBEF), which inhibits apoptosis and induces spontaneous labor...

INTRODUCTION: The selection of a sperm with good genomic integrity is an important consideration for improving intracytoplasmic sperm injection (ICSI) outcome. Current convention selects sperm by vigour and morphology, but preliminary evidence suggests selection based on hyaluronic acid binding may be beneficial. The aim of the Hyaluronic Acid Binding Sperm Selection (HABSelect) trial is to determine the efficacy of hyaluronic acid (HA)-selection of sperm versus conventionally selected sperm prior to ICSI on live birth rate (LBR)...

Male factor infertility accounts for approximately 50 percent of infertile couples. The male factor-related causes of intracytoplasmic sperm injection failure include the absence of sperm, immotile sperm, immature sperm, abnormally structured sperm, and sperm with nuclear damage. Our knockout and knock-in mice models demonstrated that SEPTIN12 (SEPT12) is vital for the formation of sperm morphological characteristics during spermiogenesis. In the clinical aspect, mutated SEPT12 in men results in oligozoospermia or teratozoospermia or both...
