Purpose: The aim of this study was evaluated the effect of β -mercaptoethanol on resumption of meiosis, In vivo maturation of immature mouse oocytes treated with DEHP and embryo development. Materials and Methods: NMRI mouse strain (4-6 weeks) were treated daily with 50,µI DEHP Group 1: 121 immature oocytes were matured in MEM-α medium contain FCS 5%, hCG 7.5 IU/ml, rFsH 100mIU/ml, Group 2: 12...
background: it is important to evaluate ovarian reserves prior to intracytoplasmic sperm injection (icsi) treatment. the aim of this study is to determine the accuracy of anti-mullerian hormone (amh) as a marker for ovarian reserve and to compare it with day-3 serum follicle-stimulating hormone (fsh) levels. materials and methods: in this analytic, corss-sectional study, sequential sampling was...
background: repeated in vitro fertilization (ivf) failure together with ovarian hyperstimulation syndrome (ohss) is one of the distressing situations leading couples to search for alternative treatment options. for such patients with polycystic ovarian syndrome (pcos) who have experienced ovarian hyperstimulation syndrome, mild ovarian stimulation with in vitro oocyte maturation could be a prom...
In Vitro Maturation (IVM) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. This review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. The review is based on literature reports and the author’s experience. In IVM cycles,...
Abstract Background Estradiol is an important marker of ovarian response to stimulation in ART cycles. The study tries find the correlation serum estradiol on day HCG trigger number follicles, oocytes retrieved, and mature oocytes, also, correlate per follicle oocyte HCG, oocytes. It a cross sectional using retrospective data. Results data 232 patients were analyzed. Our showed positive between...
Background and purpose: This study aimed at evaluating the effects of different doses of Licorice extract on in vitro maturation (IVM) and in vitro fertilization (IVF). Materials and methods: In this study 32 female adult mice were randomly assigned into four groups. Group I was the control, group II were estradiol valerate-induced PCOS mice (0.2cc), and groups III and IV were induced PCOS t...
BACKGROUND Milder ovarian stimulation protocols for in vitro fertilization (IVF) are being developed to minimize adverse effects. Mild stimulation regimens result in a decreased number of oocytes at retrieval. After conventional ovarian stimulation for IVF, a low number of oocytes are believed to represent poor ovarian reserve resulting in reduced success rates. Recent studies suggest that a si...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
Background: Anemia and consequently low oxygen can cause changes in the function and structure of the testis and spermatogenesis, Iron released from red blood cells, followed by the increased oxidative stress, which may cause tissue iron. This study was designed to minimize the deleterious effects of hypoxia on the genitals. Materials and Methods: Eighteen mature male mice were randomly divided...
