BACKGROUND Milder ovarian stimulation protocols for in vitro fertilization (IVF) are being developed to minimize adverse effects. Mild stimulation regimens result in a decreased number of oocytes at retrieval. After conventional ovarian stimulation for IVF, a low number of oocytes are believed to represent poor ovarian reserve resulting in reduced success rates. Recent studies suggest that a si...

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...

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 ...

Successful IVF/ICSI treatment depends on obtaining a sufficient oocyte sample and selecting patients carefully. COH (Controlled Overian Hyperstimulation) treatment in patients with poor ovarian response is one of the most important issues in IVF programmes. The ovarian response that follows ovarian stimulation is the most important determiner in ART treatment. Although many other stimulation pr...

BACKGROUND Poor ovarian response and retrieval of no oocytes following ovarian stimulation for in vitro fertilization (IVF) is a challenging problem for both the patient and the clinician. FINDINGS Recent evidence indicates that folliculogenesis occurs in a wave-like fashion indicating that there are multiple follicular recruitment waves in the same menstrual cycle. This relatively new scient...
