Models of cost-effectiveness of recombinant FSH versus urinary FSH

Cost-effectiveness modelling of recombinant FSH versus urinary FSH in assisted reproduction techniques in the UK.

BACKGROUND The purpose of this study was to undertake an economic evaluation to compare the cost-effectiveness of recombinant (r)FSH with urinary (u)FSH for attaining clinical pregnancy with assisted reproduction. METHODS Mathematical modelling was utilized incorporating a Markovian decision framework and a Monte Carlo simulation. Statistical representations of recurrent events over time were...

Ovulation induction with urinary FSH or recombinant FSH in polycystic ovary syndrome patients: a prospective randomized analysis of cost-effectiveness.

The aim of this prospective, randomized trial was to compare the clinical results and the cost-effectiveness of urinary FSH (uFSH) and recombinant FSH (rFSH) in ovarian stimulation for intrauterine insemination (IUI) cycles in polycystic ovary syndrome (PCOS) patients. One-hundred and seventy PCOS infertile patients undergoing IUI were enrolled, and protocols of ovarian stimulation with uFSH or...

Meta-analysis of recombinant versus urinary-derived FSH: an update.

BACKGROUND The study aim was to analyse the results of randomized controlled trials (RCTs) comparing recombinant FSH and urinary-derived FSH gonadotrophins [hMG, urinary purified FSH (FSH-P) and highly purified FSH (FSH-HP)] in an IVF/ICSI programme. METHODS All published truly RCTs using a long protocol of GnRH agonists for down-regulation, were reviewed. Data of pregnancy rate per started c...

Efficacy of Highly Purified Urinary FSH versus Recombinant FSH in Chinese Women over 37 Years Undergoing Assisted Reproductive Techniques

Efficacy of Highly Purified Urinary FSH versus Recombinant FSH in Chinese Women over 37 Years Undergoing Assisted Reproductive Techniques

BACKGROUND Urine derived follicle-stimulating hormone (uFSH) contains a higher proportion of acidic isoforms, whereas recombinant FSH (rFSH) contains a higher proportion of less-acidic isoforms. Less-acidic isoforms have a faster clearance, and thus a shorter half-life than the acidic FSH isoforms. The slow clearance of the acidic isoforms has a longer half-life and higher biological activity. ...
