Background: Recurrent spontaneous abortion (RSA) and in vitro fertilization (IVF) failure with unknown causes are the controversial issues that are probably related to the immune system. Objective: To compare circulating NK cells expressing activation and inhibition surface markers between patients with RSA and IVF failure with those of healthy multiparous and successful IVF control women, resp...

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...

background: endometrial secretion analysis is a non-invasive and promising method in evaluation of endometrial receptivity. objective: the aim of the present study was to assess the relationship between the success rate of ivf procedures and some endometrial secretion cytokines, including interleukin-1β (il-1β), tumor necrosis factor (tnf-α), interferon gamma-induced protein 10 (ip-10), and mon...

Oocyte retrieval guided by transvaginal ultrasound is a fundamental step in the vitro fertilization (IVF), thas performed on an outpatient basis. has been associated with pain, discomfort, and anxiety [1,2].

During the years 1984-1992, 951 couples completed 2252 in-vitro fertilization (IVF) treatment cycles at the In-Vitro Fertilization Unit of The Chaim Sheba Medical Centre. This study was conducted to evaluate the success of IVF using the cumulative pregnancy rate (CPR), with special emphasis on the optimal number of treatment cycles, the age of the patients and female infertility factors. It was...

Objective: This research was aimed to explore the role of interventional embolization in hydrosalpin resulting from In Vitro Fertilization and Embryo Transfer (IVF-ET). Methods: From 2013 to 2016, 130 patients were treated with IVF-ET in which 75 were treated with fallopian tube embolization followed by IVF-ET while others received IVF-ET without other treatments. Age, basal Estradiol (E2) valu...

A prospective, randomized study of 158 patients undergoing in-vitro fertilization (IVF) and embryo transfer was conducted to evaluate whether a shortened exposure of oocytes to spermatozoa enhances oocyte development, and subsequently influences the IVF outcome. A comparison was made between conventional treatment time and shorter exposure of retrieved oocytes to spermatozoa. Fertilization and ...

A case is reported in which a high fertilization rate was achieved by conventional in-vitro fertilization (IVF), using spermatozoa from an oligozoospermic man carrying a microdeletion of the long arm of the Y chromosome. The patient presented with idiopathic infertility of 10 years duration; the fertility status of his wife was completely normal. After IVF, five out of eight oocytes retrieved s...

In vitro fertilization (IVF) is widely used in reproduction research, but the sperm of some inbred strains of mice yield low fertilization rates in IVF. To determine the cause of this problem, we examined the effect of epididymal sperm morphology, in particular, tail bending and the presence and type of cytoplasmic droplet (CD), on fertilizability in vitro. Sperm suspensions were obtained from ...

BACKGROUND The aim of this retrospective study is to investigate the relevance of dividing oocytes and using some for traditional in vitro fertilization (IVF) and others for intracytoplasmic sperm injection (ICSI) as of the first IVF cycle in patients with unexplained infertility who have undergone 4 intrauterine insemination (IUI) cycles which produced no pregnancies. METHODS This retrospect...
