Human reproductive technologies have developed specific goals and objectives. Reproductive technologies generally aim to provide solutions to reproductive problems. Reproductive technology in animals, especially humans, evolved more slowly than the technology of reproduction in plants. Here are some explanations about reproduction in humans.
Any technology that is created by humans raises new hopes for improving the quality of life. One promising technology for couples who are difficult to obtain offspring IVF (in vitro fertilization). Maternal egg fertilization by sperm cells artificially father performed in a tube. After fertilization, the zygote will be returned to the mother's womb.
Babies who are born the first time through this process is a baby named Louise Brown of England who was born in 1978. This process is a milestone in vitro fertilization that help millions of couples in the world for memeroleh children.
Cloning become the most popular term after the birth of cloned sheep Dolly. Cloning is one way of artificial reproduction technology that utilizes manipulation of the egg. If the egg is generally fertilized by a sperm cell nucleus, in the process of cloning is a haploid egg cell nucleus is removed by special techniques. After that, his position is replaced by the nucleus of cells from other body parts, such as skin or muscle are diploid. In the sheep Dolly, the nucleus donor cell used is the sheep mammary gland cell nucleus.
Case of cloning is still a lengthy polemic since the technology is likely done in humans. If it occurs in humans, it is feared will happen deviations of the main purposes of cloning. For example, with human labor that is used for instruments of crime. Experiments on human cloning is still a violation of applicable laws around the world.
