Development of Mouse Preantral Follicle after In Vitro Culture in A Medium Containing Melatonin

OBJECTIVE Improvements in cancer treatment have allowed more young women to survive. However, many cancer patients suffer from ovarian failure. Cryopreservation is one of the solutions for fertility restoration in these patients. The cryopreservation of isolated follicles is a more attractive approach in the long term. Many endocrine and paracrine factors can stimulate the granulosa cells of pr...

Melatonin Impact on In Vitro Development of Mouse Preantral Follicles and Oocyte Maturation

Introduction: Melatonin acts as an indirect antioxidant and is a powerful direct free radical scavenger and direct responses to melatonin in the gonads are detected. This study aims to investigate the influence of different doses of melatonin on preantral follicle development and oogenesis of in vitro cultured mouse ovarian follicles. Materials and Methods: Preantral follicles with diamet...

P-83: Development of Mouse Preantral Follicles in Fibrin-Alginate Matrix during In Vitro Culture

Background This research was conducted to assess preantral follicle development in fibrin alginate matrix following ovarian tissue vitrification MaterialsAndMethods Ovaries of 13-day-old NMRI female mice were removed and placed in control and vitrification groups. Vitrification group ovaries were transferred in media containing ethylene glycol, dimethyl sulphoxide, and sucrose then were plunged...

Inhibin A and B secretion in mouse preantral follicle culture.

Conditioned media from single mouse ovarian follicles cultured from the early preantral stage up to complete maturity were analysed for different immunoreactive inhibin forms. The inhibin assays measured (i) alpha-specific inhibin, as represented by a mix of 32 and and 57 kDa inhibins, inhibin precursors, alpha-subunit and its precursors; (ii) dimeric inhibin A; and (iii) dimeric inhibin B. The...

P-107: Vitrification and In Vitro Culture of Mouse Preantral Follicles in Presence of Growth Factors

Background: Cryopreservation of oocytes is an effective technology in assisted reproductive technology. Although successful vitrification of gametes has been reported in several mammalian species, the survival is generally low. The aim of this study was to investigate the effects of fibroblast growth factor (FGF) and hepatocyte growth factor (HGF) on preantral follicle development after vitrifi...
