BACKGROUND Several systematic reviews compared recombinant gonadotrophin with urinary gonadotrophins (HMG, purified FSH, highly purified FSH) for ovarian hyperstimulation in IVF and ICSI cycles and these reported conflicting results. Each of these reviews used different inclusion and exclusion criteria for trials. Our aim in producing this review is to bring together all randomised studies in t...

The article "Establishing a combined stimulation protocol hFSH followed by rFSH might represent a breakthrough in the IVF practice" by S. Gerli, G.C. Di Renzo, published in Eur Rev Med Pharmacol Sci 2013; 2013; 17 (15): 2091-2096 has been withdrawn.

OBJECTIVE Since there is still controversy regarding the best first-line choice for ovulation induction (OI) other than clomiphene citrate (CC) in infertile women diagnosed with polycystic ovary syndrome (PCOS), the aim of the present study was to compare recombinant human FSH with CC as the first course of OI in these women. MATERIALS AND METHODS In this pilot randomized controlled trial, 10...

BACKGROUND Poor ovarian response is a common clinical problem, affecting up to 26% of IVF cycles. For these women, addition of recombinant luteinizing hormone (rLH) to ovarian hyperstimulation with recombinant FSH has a beneficial effect on ongoing pregnancy rates, but its effect on the yield of top-quality embryos is unknown. METHODS We conducted a randomized controlled trial in women expect...

Background To compare two different gonadotropin preparations, human menopausal gonadotropin (hMG) and recombinant follicle-stimulating hormone (rFSH), combined with clomiphene citrate (CC) in women with unexplained infertility undergoing intrauterine insemination (IUI). MaterialsAndMethods In this prospective clinical trial, couples prepared for IUI cycles were randomly allocated to two groups...

background: despite the large number of papers published on the efficiency of different exogenous gonadotropins, no confirmed protocol exists. therefore, the aim of the present study was to compare the efficacy of 4 exogenous gonadotropins in ivf/icsi cycles. methods: this study, performed from january 2014 to may 2014, recruited 160 women referred to ghadir mother and child hospital and dena h...

trophins [OR 0.89 (95% CI 0.65±1.22)]. (Figure 2). In addition, recalculating the clinical pregnancy rate per cycle started after extracting the correct data from the paper of The European and Israeli Study Group on highly puri®ed hMG versus rFSH (2002) would result in OR 95% CI that reached unity, meaning that there is no statistically signi®cant difference between both types of gonadotrophins...

The results of several studies about the effectiveness of recombinant luteinizing hormone (rLH) supplementation in poor responder in vitro fertilization (IVF) patients were conflicting. To evaluate the current available data regarding the efficacy of rLH supplementation in poor responders, a meta-analysis was performed. A systemic search was performed without language limitation but restricted ...
