In-vitro fertilisation

Extracts from this document...


In-vitro fertilisation * Introduction In vitro fertilization (IVF) is a technique in which egg cells are fertilized by sperm outside the woman's womb, in vitro. IVF is a major treatment in infertility when other methods of assisted reproductive technology have failed. The process involves hormonally controlling the ovulatory process, removing ova (eggs) from the woman's ovaries and letting sperm fertilize them in a fluid medium. The fertilized egg (zygote) is then transferred to the patient's uterus with the intent to establish a successful pregnancy. * Method of fertilization The method of fertilization contains these steps: Ovarian stimulation, Oocyte retrieval, Fertilization, Selection and Embryo transfer. (1) At first, the treatment are taken by the female when the period have started three days, this helps to stop ovulation. ...read more.


Several embryos may be passed into the uterus to improve chances of implantation and pregnancy. � My opinion: Although in-vitro fertilization is a technique work, it has many disadvantages.

Basically, it's not a personal ability, it depends on what the body is or how old is the partner. And of course, the opportunity and the luck are very important, because these decide if the fertilization is successful.

So, In vitro fertilization is not good to do. Everything has two sides, doesn't it? The benefits are In vitro fertilization is very convenient, although there are many steps, it helps people to fertilize outside body. * Social: In vitro fertilization has raised extremely complex legal and ethical questions relating to parenthood, children, and the beginning of life. The law often has not responded adequately to IVF. This inadequacy--combined with the gap between new applications of the technology and the development of relevant law--has culminated in highly variable regulation internationally. The development and effects of IVF continue to be difficult to control because the treatment of infertility is unregulated in the United States and many other countries. ...read more.
