abstract ovarian tissue freezing or cryopreservation might be the only acceptable method for preserving the young women fertility, before radiotherapy or chemotherapy. this technology might be used for patients with recurrent ovarian cysts or endometriosis, without ovarian stimulation. many efforts have made to improve cryopreservation conditions that should be seriously considered for cancer p...

background and objective: the effect of opioids on the reproductive system has been studied as an attractive research field. in this study, the effect of morphine as an analgesic opioid was evaluated on the ovarian polycystic induction in the rat. materials & methods: in this study, 24 female virgin wistar rats weighing 200-250 g were injected with morphine (1-10 mg/kg/day) for 9 days. cont...

in this study we investigated histopathological changes of mice ovarian tissues following long-term administration of copper sulfate and induction of chronic copper poisoning. the study comprised of three different groups of twenty one mice as follows: the first group (group 100) which treated by gavage with copper sulfate at a dose of 100 mg kg-1 for 5 weeks. the second group (group 200), whic...

this manuscript reviews the present knowledge related to folliculogenesis in sheep.folliculogenesis starts with formation of primordial follicles before birth, present as a pool containing a certain number of follicles. by the attainment of puberty, a group of follicles from that pool starts to grow, a process known as primordial follicle activation or recruitment. the number of growing primord...

ovarian hemangiomas are benign and rare tumors of female genital tract with less than 60 reported cases in the literature. a 38- yr- old woman was admitted to be’sat hospital, tehran, iran in 2012, due to severe abdominal pain. ultrasound evaluation revealed a 6 cm left ovarian cystic mass and serum tumor markers were normal. then, left salpingo-oophorectomy was performed for the patient. micro...

the association of secreted frizzled related protein type 4 (sfrp4) as an antagonist of wnt mole-cules in apoptotic events has been reported previously. moreover, its increased expression has been reported in the ovary of women with polycystic ovary (pco). we have demonstrated in-creased sfrp4 in pco-induced rat ovary related to an increased number of apoptotic follicles showing nuclear ?cateni...

background: recently, there are increasing concerns and interests about the potential effects of electromagnetic field (emf) on both human and animal health. objective: the goal of this study was to evaluate the harmful effects of 50 hz non-ionizing emf on rat oocytes. materials and methods: in this experimental study 30 rats were randomly taken from laboratory animals and their ags and weights...

Abstract Evolutionarily young genes are usually preferentially expressed in the testis across species. Although it is known that older generally more broadly than younger genes, properties shaped this pattern unknown. Older may gain expression other tissues uniformly, or faster certain others. Using Drosophila gene data, we confirmed previous findings disproportionately biased and ovary biased....
