ET is the final crucial step in IVF treatment. However, it has been demonstrated by multiple investigators that great care and patience should be observed when performing an ET, because even small differences in methods may affect pregnancy rates. Dummy ET before the actual transfer can help the outcome of ART. Placement of the embryos 2 cm below the uterine fundus by ultrasound-guided ET is strongly suggested. Proper evaluation of the uterine cavity to ensure the proper placement of the embryos is recommended. Cervical mucus can be a serious obstacle in proper embryo replacement. All efforts should be made to avoid difficult embryo transfers provoking bleeding or uterine contractions. Since the very early days of IVF, the value of soft embryo transfer catheters has been recognized. Finally, the physician has to be absolutely sure that the catheter has passed the internal cervical os and the embryos are delivered gently inside the uterine cavity.

Chinese scientists have created genetically-engineered, extra-muscular dogs, after editing the genes of the animals for the first time. The scientists create beagles that have double the amount of muscle mass by deleting a certain gene, reports the MIT Technology Review. The mutant dogs have “more muscles and are expected to have stronger running ability, which is good for hunting, police (military) applications”, Liangxue Lai, one of the researchers on the project. Now the team hope to go on to create other modified dogs, including those that are engineered to have human diseases like muscular dystrophy or Parkinson’s. Since dogs’ anatomy is similar to those of humans’, intentionally creating dogs with certain human genetic traits could allow scientists to further understand how they occur

DALEY: Well, I'm reminded of the book by Aldous Huxley called "Brave New World" where human reproduction was highly mechanized, where people were brought forth with certain traits that advantaged them over others. This creates divisiveness in a society. It creates the haves and the have-nots. And we know there are already pressures in our society that cause this great schism. These are fundamental questions of social justice. And whenever we have a new technology that can call those issues into question, we have to go forward with prudence and thoughtfulness and caution.
