Gonadotropin-releasing hormone (GnRH) analogues are commonly used in clinical practice
to prevent premature luteinizing hormone (LH) surge during In-Vitro Fertilization/Intra …

To allow selection of embryos for transfer after in vitro fertilization, ovarian stimulation is
usually carried out with exogenous gonadotropins. To compensate for changes induced by …

BACKGROUND: We aimed to determine the efficacy of ovarian hyperstimulation protocols
employing a GnRH antagonist to prevent a premature LH rise allowing final oocyte …

Ovarian stimulation for IVF is known to affect luteal phase function. The endometrium in IVF
cycles is thus subject to an altered endocrinological environment and to a possible direct …

The influence of ovarian stimulation on endometrium receptivity has been inadequately
addressed in medical literature. Hormonal effects of ovarian stimulation on endometrial …

The present review describes, on the basis of the currently available evidence, the
consensus reached by a group of experts on the use of gonadotropin-releasing hormone …

We believe that appropriate comparison of optimal GnRH agonist and antagonist regimens
has not been performed yet. Currently available meta-analyses included all comparative …

OBJECTIVE: To assess the effect of altering the timing of hCG administration on ongoing
pregnancy rates in patients stimulated with recombinant FSH (rec-FSH) and GnRH …

This randomized, controlled trial verifies whether patients with recurrent failed implantation
benefit from preimplantation genetic diagnosis for aneuploidy, as compared with …

OBJECTIVE: To critically discuss the current protocols for the management of controlled
ovarian hyperstimulation in assisted reproduction technology. DESIGN: Review of the …
