The effect of 100 and 200 IU per day recombinant FSH (rFSH) on numbers of oocytes retrieved and the total dose used in ovarian stimulation before intracytoplasmic sperm injection was investigated in a double-blind, randomized multicentre trial. A total of 91 women was treated with a low-dose protocol and 88 with a high-dose regimen at five centres. For each started cycle, significantly more ooc...

There has been much debate about the role of luteinizing hormone (LH) during follicle stimulating hormone (FSH)-treated ovarian stimulation for assisted reproduction, where the endogenous LH is suppressed using a gonadotrophin-releasing hormone analogue. The requirement for LH in oestradiol biosynthesis is established, but other effects of 'insufficiency' are less clear, and little attention ha...

BACKGROUND Milder stimulation protocols are being developed to minimize adverse effects of ovarian stimulation in in vitro fertilization (IVF) programs. A drawback is the possibility of an increased rate of insufficient ovarian response. This study aimed to develop a prognostic model for the prediction of cycle cancellation due to insufficient response to mild stimulation. METHODS A total of ...

Background. The first biosimilar of recombinant follicle stimulating hormone (rFSH) launched in Europe was Bemfola® 2014 following a clinical development programme demonstrating efficacy and safety to the satisfaction European Medicines Agency. Since then increasing use rFSH has provided opportunity study both effectiveness across whole population variation during routine care real-world settin...

INTRODUCTION Superovulation-intrauterine insemination (SO-IUI) is the most common assisted reproductive technique (ART) in the world, with good evidence of efficacy and cost-effectiveness. However, parameters affecting its success have not been consistently reported. So in this study, we aim at determining the parameters influencing the success rate of SO-IUI. MATERIALS AND METHODS We conduct...

The aim of this study was to determine the individual and combined effect of activin and follicle stimulating hormone (FSH) on somatic and germ cell development in cultured pre-antral follicles. Pre-antral bovine follicles (mean diameter 157 +/- 3, range 132-199 microm) were cultured for 8 days in serum-free medium in the presence of either 100 ng/ml of recombinant human activin A (rhAct A), 10...

We report the case of a 31 year old woman who presented for management of her documented polycystic ovarian syndrome (PCOS). Her body mass index at the time of treatment was 35.9 kg/m 2. Previously, she had conceived following ovulation induction with urinary gonadotrophins in 1992 and gave birth to a son. She now wished to have another child. Induction of ovulation with clomiphene citrate (Clo...
