objective: ovarian and follicle transplantation may preserve fertility in young cancer survivors. in this study, we have transplanted preantral follicles using fibrin gel as a carrier and fibrin gel supplemented with platelet lysate (pl) as a rich source of angiogenic and growth factors. the purpose of this study was to evaluate the role of fibrin gel and pl in follicle transplantation. materia...

BACKGROUND Previous studies have demonstrated that pre-pubertal aryl hydrocarbon receptor knockout (AHRKO) mice have slow antral follicle growth and reduced capacity to produce estradiol compared to wild-type (WT) mice. Although previous studies have suggested that this is likely due to a reduced ability of the AHRKO follicles to respond to follicle-stimulating hormone (FSH), this possibility w...

BACKGROUND This study evaluated the effect of pituitary desensitization on the early growing follicle population through assessment of serum anti-Mullerian hormone (AMH) concentration. Other markers of ovarian reserve, basal follicular stimulating hormone (FSH), luteinizing hormone (LH), estradiol, inhibin-B and three-dimensional ultrasound ovarian parameters were also assessed for comparison. ...

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...
