OBJECTIVE To compare the outcomes of protocols for ovarian stimulation with recombinant hCG microdose, with GnRH agonists and antagonists for pituitary suppression. DESIGN Prospective nonrandomized clinical trial. SETTING A private assisted reproduction center. PATIENT(S) We studied 182 patients undergoing intracytoplasmic sperm injection (ICSI) cycles, allocated into two groups: GnRH ago...

OBJECTIVE To determine the efficacy and efficiency of two fixed doses of recombinant follicle-stimulating hormone (FSH) in controlled ovarian hyperstimulation. DESIGN Randomized, double-blind clinical trial. SETTING Fifteen IVF clinics in Argentina, Brazil, Chile, Colombia, Mexico, and Venezuela. PATIENT(S) Women between 30 and 39 years of age undergoing IVF or intracytoplasmic sperm inje...

INTRODUCTION The aim of this study is to comprehensively evaluate whether FSH administration to the male partner of infertile couples improves pregnancy rate, spontaneously and/or after assisted reproductive techniques (ART). METHODS Meta-analysis of controlled clinical trials in which FSH was administered for male idiopathic infertility, compared with placebo or no treatment. Randomization w...

BACKGROUND Hypogonadotropic hypogonadal women are characterized by ovarian functionality deficiency, caused by low concentrations of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). To recover reproduction functionality, recommended therapies for ovarian induction involve injections of FSH and LH medications. OBJECTIVE Since important differences exist between recombinant and ...

OBJECTIVE To compare the pregnancy outcome in patients undergoing in vitro fertilization-embryo transfer (IVF-ET) cycles, using human derived follicle-stimulating hormone (FSH) or recombinant FSH for ovarian stimulation protocols. DESIGN Prospective, multi-centre, randomized controlled trial. PATIENTS 115 infertile patients undergoing a first attempt of in vitro fertilization and embryo tra...

Hypogonadotropic hypogonadism is defined as a medical condition with low or undetectable gonadotropin secretion, associated with a complete arrest of follicular growth and very low estradiol. The main cause can be traced back to an irregular or absent hypothalamic GnRH secretion, whereas only a minority suffers from a pituitary disorder. The choice of treatment to reverse this situation is a pu...

the aim of this study was to evaluate the outcomes of adding low-dose hcg (human chorionic gonadotropin), as an lh active supplement, to a gnrh antagonist protocol in patients undergoing assisted reproduction techniques. in this parallel-group randomized clinical trial, 137 infertile female outpatients aged 20 - 39 years were randomized into two groups: hcg group and non-hcg group. all patients...
