Facing with infertile couples who suffer from infertility, reproductive experts have thought about how to help them have babies successfully. And the reproductive experts hope that through the use of ovulation drugs, they can get more eggs, manufacture more embryos, and then implant more embryos in order to increase the pregnancy rate and birth rate. Some questions thus arise here, whether embryos are the same as any other human cells that are just objects of private rights before implantation, so the owner can dominate, dispose and trading, or the embryo has some kind of legal status that the government has the duty to protect it? The embryos before implantation or surplus embryos after implantation can be used for research or be destroyed casually? Whether it is permitted to create embryos for research? Prior to implantation, for the purpose of diagnosis if there are hereditary diseases, even only for making "perfect baby", shall we take a pre-implantation genetic screening? Could we implant more embryos to increase pregnancy rates? Who has the right to decide how many embryos should be implanted? Shouldn't there be any restrictions for the number of embryos implanted? Are the limits of the number of embryos implanted in Artificial Reproductive Law of Taiwan appropriate or not? Multiple pregnancy for pregnant women, fetuses, their families, and even the society as a whole has very serious negative effects, so how to avoid it generated from the assisted reproductive technology? Facing with multiple pregnancy, can we proceed the multifetal pregnancy reduction arbitrarily? These questions are not easy to answer, but if we appreciate the legal status of the embryos, that will allow us keep prudential attitude to the practical applications of the embryos, and we can understand the human embryos are with humane factors. Neither can they be over infringed, nor can they be stunted. Reasonable use of human embryos to this society will bring more benefits than harm.
