چکیده
Success rates with in vitro fertilization (IVF) continue to improve as we gain insight into optimal culture conditions for gametes and embryos. New procedures such as in vitro egg maturation, preimplantation genetic testing, single embryo transfer, and oocyte freezing hold the promise of reducing the cost, inconvenience, and risks of IVF, as well as preserving future fertility. We provide an overview of the current and experimental assisted reproductive technology techniques.

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...

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...

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...
