Abstract While intracytoplasmic sperm injection (ICSI) is an asset in human Assisted Reproduction Technologies (ART), its outcomes, terms of blastocyst, still unacceptably low ruminants. The picture typically found ICSI derived bovine and ovine embryos asymmetry between a high activation rate, marked by pronuclear development, first cleavage rate. Abnormal centriole function has been indicated ...

Intracytoplasmic sperm injection (ICSI) is used to fertilize oocytes by delivering spermatozoa directly into the ooplasm using micromaniplating devices. Mammalian ICSI, was initially designed to examine the fertilization steps in ooplasm.1 ICSI has wide clinical application and become the method of choice to help overcome male infertility, however, the survival rates and fertilization rates of ...

Abstract Study question Can P-ICSI improve the clinical outcomes of ICSI, such as degeneration, fertilization and development to blastocyst, compared conventional ICSI (C-ICSI)? Summary answer can by increasing number fertilized oocytes decreasing degenerated after ICSI. What is known already In human IVF-ET, some are damaged when retrieved inseminated The application has been limited although ...

Objective Objective: The aim of this study was to investigate the effects of vaginal sildenafil on the outcome of patients with at least two times of unsuccessful IVF / ICSI. MaterialsAndMethods Method and Material(s): A total of 66 infertile women aged ≤ 38 years, with a history of normal ovarian reserve, two prior consecutive failed IVF/ICSI attempts, hCG day endometrial thickness

BACKGROUND The aim of this study was to investigate the influence of body mass index (BMI) on the in vitro fertilization (IVF) treatment outcomes in a cohort of women undergoing their first IVF, using an intracytoplasmic sperm injection (ICSI). METHODS This retrospective cohort study included 298 cycles from women younger than 38 years old undergoing IVF-ICSI at a university infertility clini...

In Denmark, preimplantation genetic diagnosis (PGD) is offered within the public healthcare to families with a known risk of an inherited disease in a child - as an alternative to prenatal diagnosis. It is a well-established technique with rather well-described perinatal- and neonatal outcomes, being comparable to what is seen following in vitro fertilization/intracytoplasmic sperm injection (I...

OBJECTIVE To determine if strict morphology correlates with outcome parameters in couples undergoing intracytoplasmic sperm injection (ICSI). DESIGN Retrospective review. SETTING Academic nonprofit IVF center. PATIENT(S) Couples undergoing IVF/ICSI. INTERVENTION(S) In vitro fertilization and ICSI. MAIN OUTCOME MEASURE(S) Samples were evaluated for total sperm count, motlity, progressi...

background: c-reactive protein (crp) can be increased after hormonal stimulations. the changes of crp might affect the success of in-vitro fertilization (ivf). objective: the aim of this study was to determine the possible relationship between the serum crp level and outcome of controlled ovarian stimulation, and pregnancy rate in patients undergoing ivf or intra cytoplasmic sperm injection (ic...

background: endometriosis is one of the most challenging diseases that constitute 20% - 40% of women searching for their infertility diagnosis. objective: this study was undertaken in order to compare the outcome of in vitro fertilization/intracytoplasmic sperm injection (ivf/icsi) in women with endometriosis, and tubal factor infertility as controls. materials and methods: from 2005 to 2006 a ...

the microdose gnrh agonist (gnrh-a) flare protocol may have a particular value for previously poor responders in whom it has been observed to stimulate dramatic increases in serum fsh. the purpose of this study was to determine the effects of microdose gnrh-a in poor responders. this is a clinical trial with before and after design. this study was done in research and clinical center for infert...
