spermatids are the earliest male germ cells with one set of haploid chromosomes. after experiments, mainly in rodents, the spermatid injection was introduced in human assisted reproduction to the treatment of men with non-obstructive azoospermia. spermatid injection is a technique with particular difficulties that may negatively influence the outcome. the identification, isolation and the asses...

Background: The aim of this study was to determine the outcome of IVF/ ICSI by modification of embryo transfer technique following embryo transfer. Materials and Methods: In this randomized trial study, two groups of infertile women (n = 55) aged %40 years underwent in vitro fertilization or intracytoplasmic sperm injection treatment cycles with or without 0.2 mL of air pushed into the catheter...

Background The objective of this study was to evaluate the relationship between protamine deficiency, and acrosomal integrity with fertilization and pregnancy rate in patients undergone in vitro fertilization (IVF). MaterialsAndMethods Semen samples from 70 infertile couples undergoing IVF at Isfahan Fertility and Infertility center were assessed in this study. Semen analysis was carried out ac...

assessment of embryo quality in order to choose the embryos that most likely result in pregnancy is the critical goal in assisted reproductive technologies (art). the current trend in human in vitro fertilization/embryo transfer (ivf/et) protocols is to decrease the rate of multiple pregnancies after multiple embryo transfer with maintaining the pregnancy rate at admissible levels (according to...

ohtahara syndrome or ealy infantile epileptic encephalopathy is a rare cause of epileptic seizures during infancy and represents the earliest type of age related symptomatic generalized epilepsies. the main etiologic factor associated with ohtahara syndrome is cerebran dysgenesis. this case was the product of in vitro fertilization (ivf) after 18 years of infertility . neuroimaging findings con...

objective: to compare the pregnancy outcomes achieved by in vitro fertilization (ivf) between minimal stimulation and conventional antagonist protocols in poor ovarian responders (pors). materials and methods: in this randomized controlled trial, 77 pors undergoing ivf were selected and divided into two groups. first group was the minimal stimulation group (n = 42) receiving 100 mg/day clomiphe...
