background: repeated implantation failure (rif) is a major challenge in reproductive medicine and despite several methods that have been described for management, there is little consensus on the most effective one. objective: this study was conducted to evaluate the effectiveness of platelet-rich plasma in improvement of pregnancy rate in rif patients. materials and methods: twenty women with ...

OBJECTIVE There are currently no local data on the sperm retrieval and pregnancy rates in in-vitro fertilisation and testicular sperm extraction cycles, especially with regard to the presence of genetic abnormalities. This study aimed to determine the sperm retrieval and pregnancy rates in infertile couples who underwent in-vitro fertilisation and testicular sperm extraction for non-obstructive...

background polycystic ovary syndrome (pcos) is a common disease in young women that is associated with infertility and other complications such as obesity, hirsutism and insulin resistance and also the disorder that mostly is specified with oligomenorrhoea or amenorrhea with clinical or laboratory evidence of hyperandrogenemia. objectives the purpose of this study was to investigate whether mea...

Ovariectomized ewes (n=22; 68.76+/-2.34 kg initial body weight; 2.9+/-0.1 initial body condition score) were individually fed one of three diets: (1) control (phytoestrogen-free; n=7), (2) flax containing diet (n=8), or (3) linseed meal (LSM) containing diet (n=7) to investigate the rate of progesterone (P4) clearance. On day 20 of feeding (day 0=initiation of treatment), a P4 releasing device ...

objective: the objective of this study is to compare rates of pregnancy and ivf parameters in subjects who were stimulated with follicle stimulating hormone (fsh) plus either recombinant human luteinizing hormone (r-lh) or human menopausal gonadotropins (hmg), in long gonadotropin releasing hormone (gnrh) agonist ivf protocols. materials and methods: this is a cohort study of patients undergoin...

Objective Improvement in sperm density and motility after varicocelectomy have been widely reported for men with oligoasthenoteratospermia (OAT),However the value of varicocelectomy in azoospermic men remain controversial.In this study we have evaluated the outcome of microsurgical varicocelectomy in nonobstructive azoospermic (NOA) men with clinical varicocele in five years in royan institute....

Background:Expression of granulocyte colony stimulating factor (G-CSF) and its receptors in embryo and endometrium implicates the involvement of this glycoprotein on implantation process. In the present study, we aimed to evaluate the impact of routine use of subcutaneous administration of G-CSF on pregnancy outcomes in intracytoplasmic sperm injection (ICSI) patients. <strong...

Objective The objective of this study is to compare rates of pregnancy and IVF parameters in subjects who were stimulated with follicle stimulating hormone (FSH) plus either recombinant human luteinizing hormone (r-LH) or human menopausal gonadotropins (hMG), in long gonadotropin releasing hormone (GnRH) agonist IVF protocols. MaterialsAndMethods This is a cohort study of patients undergoing IV...

  Background: Gestational diabetes mellitus (GDM) is a form of diabetes that occurs in pregnancy. GDM, defined as glucose intolerance, first diagnosed or initiated during pregnancy affects 1-14% of pregnancies based on various studies. Screening and early diagnosis and appropriate glycemic control can improve prenatal outcomes. Telephone follow-up seems to be a reasonable way for pregnant women...

background: we often see patients with a thin endometrium in art cycles, in spite of standard and adjuvant treatments. improving endometrial growth in patients with a thin endometrium is very difficult. without adequate endometrial thickness these patients, likely, would not have reached embryo transfer. objective: we planned this study to investigate the efficacy of intrauterine granulocyte co...
