BACKGROUND Conventional ovarian stimulation and the transfer of two embryos in IVF exhibits an inherent high probability of multiple pregnancies, resulting in high costs. We evaluated the cost-effectiveness of a mild compared with a conventional strategy for IVF. METHODS Four hundred and four patients were randomly assigned to undergo either mild ovarian stimulation/GnRH antagonist co-treatment...

This article is a systematic review of the literature on utilization of gonadotrophin-releasing hormone antagonists (GnRH-ant) for ovarian stimulation for IVF in special patient groups. Summarized by meta-analysis are the data from randomized controlled trials (RCT) in which GnRH-agonist (GnRH-a) and GnRH-ant were compared (eight RCT for poor response, four RCT for PCOS). Also reviewed are the ...

background: acceptance of uterus and reaction between endometrium and embryo has an important role for implantation. muc1 an integral membrane mucin is expressed on the apical surface of uterine epithelial cells and could have effects on its receptivity. objective: the aim of this study was to evaluate the changes in muc1 expression of gravid mouse endometrium with and without hyperstimulation ...

background: the preparation of endometrium for embryo reception is dependent on the ovarian hormones, which are affected by ovarian hyperstimulation procedure. objective: the aim of this study was to evaluate the changes in morphometrical indices of endometrium by the daily injection of progesterone after mouse ovarian induction. materials and methods: adult virgin female mice were selected and...

Aim: The present study was aimed at finding out the age specific best protocol for ovarian stimulation, particularly for advanced age group. Materials and Methods: This retrospective analysis was carried out from July 2005 to June 2009 in 617 cycles of In-vitro Fertilization (IVF) in different age group patients, performed at our centre. 617 patients having indications for female factor inferti...

background: one the main aspects of an in vitro fertilization (ivf) cycle is to avoid any possible systemic damage to women undergoing to a controlled ovarian hyperstimulation (coh). the aim of this work is to evaluate renal and hepatic function blood tests in patients undergoing controlled ovarian hyperstimulation during ivf cycles. materials and methods: all patients received a long stimulati...

abstract the gnrh analogue (agonist and antagonist gnrh) changed ovarian stimulation. on the one hand, it improved chances of pregnancy to obtain more oocytes and better embryos. this leads to an ovarian hyper-response, which can be complicated by the ovarian hyperstimulation syndrome (ohss). on the other hand, the gnrh analogue can prevent the incidence of ohss: gnrh antagonist protocols, gnrh...

Objective This retrospective study compared the effect of the luteal phase ovarian stimulation protocol (LP group) with the gonadotrophin-releasing hormone (GnRH) antagonist protocol (AN group) in women with poor ovarian responses. Methods Ovarian stimulation was initiated with 225 IU of human gonadotrophin (hMG) daily. When the dominant follicle diameter exceeded 13 mm, 0.25 mg of a GnRH antag...

OBJECTIVE To evaluate the double-stimulation protocol efficacy over conventional ovarian stimulation in recovering a more adequate number of oocytes and increase the number of embryos to be transferred or to be genetically analyzed. METHODS A retrospective and comparative study with 13 patients who underwent unsuccessful in vitro fertilization (IVF) cycles with a conventional antagonist ovari...
