background: polycystic ovary syndrome (pcos) is a common cause of ovulatory disorders and infertility with high lh to fsh ratio. in order to prevent further increase of lh and follicle atresia, different regimens for ovulation induction have been recommended using fsh alone.   objective: this study was performed in pcos patients to compare art outcomes in cycles induced by fsh alone, using eith...

BACKGROUND Previous studies have explored the effect of granulocyte colony stimulating factor (G-CSF) administration on the outcome of assisted reproductive technology (ART), and came into controversial conclusions. The present meta-analysis aims to assess whether G-CSF administration has beneficial effect on the outcome after ART. METHOD The electronic databases Pubmed, Embase and Google Sch...

BACKGROUND Human fertility has been declined all over the world. Advanced women's age is one of the most important factors in determining the success of reproduction and ageing has negative impact on ART outcome and advanced female age decreases the chance of live birth rates achieved using ART, especially after 40 years of age. OBJECTIVE To evaluate ART outcomes regarding to pregnancy, abort...

Cumulative pregnancy rate has been significantly increased since frozen-thawed embryo transfer was applied in ART cycles. This method has become an essential part of IVF/ICSI treatment. Luteal phase support has been proven to be associated with higher rate of live birth rate. Human chorionic gonadotropin (HCG), and progestrone have been successfully used for luteal phase support in ovarian stim...

The energy absorption of concrete filled, hollow-steel bracing was analyzed respect to geometric and mechanical parameters including the width-to-thickness section ratio, slenderness level, and strength of the steel and concrete. Local buckling and ductility were also investigated with respect to variation in the cross-section. The infill increased the compression resistance, even after multipl...
