Objective To investigate the effect of sperm DNA fragmentation on the fertilization rate, embryo development and pregnancy outcome of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in a cohort of Chinese couples. Methods Infertile couples that had undergone assisted reproductive technology at our centre between January 2011 and December 2013 were included in this retro...

background: recurrent spontaneous abortion (rsa) and in vitro fertilization (ivf) failure with unknown causes are the controversial issues that are probably related to the immune system. objective: to compare circulating nk cells expressing activation and inhibition surface markers between patients with rsa and ivf failure with those of healthy multiparous and successful ivf control women, resp...

recent years, the field of medicine has experienced a significant transformation through integration telemedicine. Telemedicine, use telecommunications technology to provide remote healthcare services, revolutionized various medical specialties, including realm in vitro fertilization (IVF) programs.

BACKGROUND Repeated in vitro Fertilization (IVF) failure together with Ovarian Hyperstimulation Syndrome (OHSS) is one of the distressing situations leading couples to search for alternative treatment options. For such patients with Polycystic Ovarian Syndrome (PCOS) who have experienced Ovarian Hyperstimulation Syndrome, mild ovarian stimulation with in vitro oocyte maturation could be a promi...

Background: One of the efforts that can be done to overcome infertility is In Vitro Fertilization (IVF) or IVF process a in which egg fertilized by sperm outside body. Where effort, hormone stimulation carried out, principle, an effort add number hormones from (exogenous hormone) functions as control reproductive process, so cycle accelerated out its natural environment. Given many risks arise,...

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...

Background: The efficiency of in vitro fertilization (IVF) is still low to be developed to blastocyst stage probably because of environmental conditions. It is likely that in vitro environment can not exactly mimic in vivo environment due to differences in media, metabolic content, atmospheric composition, temperature and pH. Therefore it may affect embryo quality by changing in embryo gene exp...

in order to do in vitro fertilization (ivf), 435 oocytes were collected from 20 super ovulated nmri female mice, in m2 media with 4% bsa. 85% (n=370) of collected oocytes were in mii phase. epididymal sperms were added to 332 oocytes in t6 media drops with 4% bsa and incubated. fertilization rate was 79.8% (n=265) out of which 27.5% (n=73) grew to morula and 20.8% (n=55) achieved blastocyst sta...
