Evaluation of the all-trans retinoic acid (t-RA) effects on in vitro maturation (IVM) and in vitro fertilization (IVF) of immature mouse oocytes in the presence and absence of granulosa cell monolayer. Denuded oocytes isolated from mice ovaries and matured in IVM medium alone (Control I), IVM medium in the presence of granulosa cells (Control II), IVM(More)
The present research investigated the effects of two vitrification methods on sheep ovarian tissue. The base medium (BM) of the vitrification solutions contains 60% HEPES tissue culture medium (HTCM), 15% ethylene glycol (EG) and 15% dimethyl sulfoxide (DMSO). Ovarian cortex pieces were dehydrated by two different regimens, the 2-step which consisted of 50%(More)
BACKGROUND This study aimed to assess follicle survival after xenotransplantation of sheep ovarian tissue into male and female immunodeficient rats. We evaluated the effects of gonadotropin treatment on follicular development in the transplanted tissue. MATERIALS AND METHODS In this experimental study, sheep ovarian cortical strips were transplanted into(More)
