In the growing follicle, communication between the oocyte and its surrounding follicular cells is essential for normal oocyte and follicular development. Maturation of the fully grown oocyte in vivo is associated with the loss of cumulus cell-oocyte gap junctional communication, preventing entry of meiotic-modulating factors such as cAMP into the oocyte. We have previously shown that oocyte and...
It is now more than three decades since the first live birth from oocyte cryopreservation. At present, oocyte cryopreservation has become a major component of Assisted Reproductive technologies (ART). Across the world, there is an increasing demand, especially for so-called ‘social egg freezing’ that allows women to preserve their fertility in anticipation of age-related fertility d...
OBJECTIVE To compare the outcomes of embryo development between oval-shaped oocyte as an abnormal morphology oocyte and a normal morphology oocyte in In Vitro Fertilization (IVF). METHODS This study was a comparative analytical study with retrospective approach which lasted from September 2014 until November 2015. For this study, we used secondary data (medical records) from 24 patients submi...
objective(s): several researchers have reported the relationship between infertility in male and varicocele for so many years but the implication of varicocele in female patients is remains elusive. here, we aim to examine the effects of unilateral varicose ovarian vein on antioxidant capacity and oocyte quality of rat ovary after the experimental creation of varicocele in female rats. material...
rate of in vitro maturation of oocytes is one of the challenges of assisted reproductive techniques. in this study we investigated the effects of supplementation of cysteamine on the rate of in vitro maturation of oocytes in two different media. germinal vesicle oocytes were collected from mouse ovary and cultured in two media (tcm199 and meme) with 0, 50, 100, 200, 500 µm/ml cysteamine. number...
the purpose of this study was to evaluate the use of glass capillary micropipette (gcm) as a vessel forvitrification of bovine oocytes. cumulus-oocyte complexes (cocs) were obtained from slaughter-house andwashed 5 to 6 times in the washing medium (tcm-199 + 20% fbs) and randomly assigned to treatment andcontrol group. in the first step of vitrification, cocs were exposed to first vitrification...
