TECHNOLOGIES AND THEIR IMPLICATIONS
This report is about the principle of reproductive and gene technologies and their implications for individuals, society and the environment.
REPRODUCTIVE TECHNOLOGIES:
Reproductive technology is the application of scientific knowledge to assist in making babies in human and animals. This is a procedure used to solve the problems of infertility like couple or lonely single females who are desperate to have children. The basic idea about these technologies is the removal of egg cells and sperm cells which are used for fertilisation to occur out side the womb to produces a new life.
A contraceptive technique is one type of reproductive technology. An example of one type of contraceptive is called contraceptive patch also known as Evra. This protects you against pregnancy and it is a small beige patch which is applied to the skin like a sticky plaster. The way the patch works is that it releases two hormones estrogen and progestogen which are similar to the natural hormones that women produce in their ovaries. This daily dose of hormones releases through the skin, into the bloodstream and it stop the ovaries from releasing an egg each month. It also makes it difficult for sperm to travel through cervix to reach an egg by thickens the mucus from the cervix. Fertilised egg is less likely to be accepted because the hormones make the lining of the womb thinner. On the contrary, this contraceptive technique does not protect you against Sexual Transmitted Infection.
Assisted reproductive technology is another type of reproductive technology. It is a methods used to achieve pregnancy by artificial means. This reproductive technology is used to treatment infertility in which both eggs and sperm are handled. The way they go about it is that they surgically remove eggs from a woman’s ovaries, combining them with sperm in the laboratory, and then insert them in the woman womb or donating them to another woman. In vitro fertilisation (IVF) is assisted reproductive technology, the non surgical procedure for IVF is called Transvaginal Oocyte Retrieval where they use sonographically needle for the recovery of egg from the ovary. Firstly the woman will take a fertility drugs in order to achieve a proper environment in the woman and to get healthy and mature eggs. Also blood test is taken and then ultrasound scans to know the right time to remove the eggs from the ovary and that time is just
