objective: cryopreservation of ovarian tissue or follicles has been proposed as an alternative method for fertility preservation. although successful vitrification of follicles has been reported in several mammalian species, the survival rate is generally low. the aim of this study was to investigate the effects of fibroblast growth factor (fgf) and epidermal growth factor (egf) on in vitro pre...

Background: This retrospective study compared pregnancy outcomes from single embryo transfer (SET) with multiple embryo transfer (MET) in too young (≤25 years) and young (>25 years) infertile patients. Materials and Methods: Data from infertile patients who referred for ART treatment to Yazd infertility center during 1992 to 2012 were studied retrospectively. Records of patients with SET or MET...

background: our previous studies revealed anethum graveolens l. caused some changes in female reproductive system that induced infertility. therefore, in this study, oocyte changes as one of probable reasons of infertility were investigated.    methods: in this study, 59 adult female rats were divided into 3 groups of control, low dose (0.5 g/kg) and high dose (5 g/kg) of dill seed aqueous extr...

the success of oocyte donation is influenced by multiple factors. we performed a retrospective analysis to evaluate prognostic factors in oocyte donation cycles. the main outcome measurements including recipient age, donor age, estradiol level in midcycle, the day of transfer and number of transferred embryos were not different in pregnant and non pregnant groups. endometrial pattern but not en...

Background: This study was conducted in order to determine whether BCB staining performed on immature bovine oocytes to assess G6pdhlevel has an impact on ivf/ivp technology in bovine embryos. Both spermatozoa and oocytes metabolize glucose through the pentose phosphate pathway (PPP), and NADPH appears necessary for gamete fusion. Activity of glucose 6-phosphate dehydrogenase (G6PDH), the key e...
