BACKGROUND The objective of this study was to assess the psychological implications of mild ovarian stimulation combined with single embryo transfer (SET) during a first IVF cycle. METHODS We conducted a randomized controlled two-centre trial. Three hundred and ninety-one couples were randomized to undergo either mild ovarian stimulation with GnRH antagonist co-treatment and SET (n=199) or co...

BACKGROUND Fragile X syndrome is associated with low ovarian reserve and poor ovarian response. The aim of this study was to investigate whether CGG repeats on the fragile X mental retardation 1 (FMR1) gene have predictive value for ovarian response to stimulation with gonadotrophins and for clinical outcome in our oocyte donation program. METHODS Oocyte donor candidates were selected accordi...

background: clomiphene citrate (cc) an agonist and antagonist of estrogen, is the first line treatment in ovarian stimulation. anti-estrogenic effect of cc in endometrial thickness and cervical mucus has negative effect on pregnancy rate. letrozole is an aromatase inhibitor has been seen that has acceptable pregnancy rate compared to cc. objective: the aim of this study was to compare the effic...

Controlled ovarian stimulation with subsequent multi-follicular development continues to be a keystone in ART. Evidence supports an individualized approach to ovarian stimulation, usually involving combinations of ovarian reserve tests, body mass index and age to tailor the exogenous gonadotropin dose, and potentially adjuvant treatment aiming for high safety and a shortening of time to live bi...
