Pnm-11: In Vitro Fertilization and The Challenges Ahead

s:1858:"Background: Infertility is defined as inability in pregnancy after one year of regular intercourse without using contraceptive methods. Approximately15-10% of couples in childbearing appears infertile. It is the cause of infertility in men and women and infertility treatment depends on type of failure and is one of the methods of treating infertility in vitro fertilization. This researc...

Impact of The Endometrioma on Ovarian Response and Pregnancy Rate in In Vitro Fertilization Cycles

P-34: Crocin Ameliorate The In Vitro Fertilization (IVF) in Mice Treated with Cyclophosphamide

Background Oxidative stress induced by cyclophosphamide (CP), as a chemotherapeutic agent, causes vulnerability of sperm and declining the fertility capacity. Then in this study the effect of crocin (saffron extract) on amelioration of these side effects was investigated. MaterialsAndMethods In this study 24 mice were divided in three groups (n=8). Control group received normal saline (0.2 ml/d...

Effect of Fresh and Frozen Semen on in vitro Fertilization and Subsequent Development of Goat Embryos

This study was undertaken to compare the efficiency of fresh and frozen-thawed buck semen on in vitro fertilization (IVF) of goat oocytes. Cumulus oocytes complexes (COCs) were collected by aspiration of 2-6 mm diameter follicles, which were obtained from slaughterhouse. Upon grading, only normal quality COCs were maturated in TCM-199 for 48 hours. The percentage of COCs reached to the M-II sta...

P-90: Ascorbic Acid Effects on In Vitro Fertilization of Ovine Oocyte with or without Cumulus Cells

Background: In vitro maturation and fertilization are techniques to increase efficiency of mammals reproduction. However, in vitro culture conditions exert an imbalance between oxidants and antioxidants which may reduce live birth and pregnancy rates when compare to in vivo conditions. Materials and Methods: The present study was conducted as a part of the ovine IVF program organized by Univers...

Impact of in vitro fertilization by fresh and frozen semen on developmental competence and cryotolerance of buffalo embryos

Production of high quality embryos in vitro needs an efficient in vitro fertilization (IVF). Seminal origin is one of the important factors that affects the success of in vitro embryo production. So our goal was to determine the effect of using fresh and frozen semen in fertilization on developmental competence and cryo-survival of buffalo embryos. Buffalo oocytes wer...
