We read with great interest the Commentary of Griesinger and Kolibianakis (2012) about scheduling oocyte retrieval in GnRH antagonist cycles. Recently, the results of a randomized trial by our group were published, reporting a significant decrease in oocyte retrieval during weekend days following administration of estradiol valerate in the luteal phase of the cycle prior to the stimulated cycle...

PREVENTION or reduction of ischemia/ reperfusion injury would be of great benefit in organ transplantation. Here we briefly report preliminary studies evaluating a combined protocol using SRI 63-441 (Sandoz Pharmaceuticals. Raritan. NJ), a potent platelet-activating factor receptor antagonist. 1 and superoxide dismutase (SOD), an oxygen free radical.scavenger, in an attempt to reduce ischemic i...

Abstract Background Along with progress in embryo cryopreservation, especially the vitrification, freeze all strategy has become more acceptable than ever. Some studies have found comparable or higher live birth rate frozen transfer (FET) fresh transfer(ET)in gonadotropin releasing hormone antagonist (GnRH-ant) protocol. However from our literature research, there been no reports about comparis...

Abstract Background Prediction of ovarian response prior to the stimulation cycle is useful in determining optimal starting dose recombinant follicle-stimulating hormone (r-FSH). This study was designed (I) evaluate which following parameters (age, AMH, and FSH) can be used as a predictor GnRH antagonist protocol, (II) determine cutoff value AMH age for predicting poor high response, (III) inve...

OBJECTIVE We devised a novel strategy, a GnRH antagonist protocol with a GnRH agonist trigger followed by frozen-thawed blastocyst transfers with long zona dissection (LZD). The purpose of this study was to investigate the clinical outcomes of this new strategy according to age. METHODS Ninety women aged less than 35 (group A) and 32 women aged 35 to 39 (group B) underwent the GnRH antagonist...

Ovarian hyperstimulation syndrome (OHSS) still remains a life-threatening complication of in vitro fertilization treatment (IVF), keeping patients and especially those, who previously experienced OHSS, from attempting infertility treatment and childbearing. The recent implementation of four new modalities: the GnRH antagonist protocol, GnRH agonist (GnRHa) triggering of ovulation, blastocyst tr...

Recent evidence suggests that exercising the antagonist musculature acutely enhances subsequent performance for the agonist musculature. The purpose of this study was to examine the effects of different rest intervals between sets for exercises that involve antagonistic muscle groups, a technique referred to as antagonist paired sets (APS). Fifteen recreationally trained men were tested for kne...

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...
