Unit 1 - IVF

This GCSE Biology quiz explores IVF, from the laboratory steps used to fertilise eggs to the ethical issues that surround fertility treatment and embryo selection.

(quiz starts below)

Fascinating Fact:

Once fertilised, the eggs develop into early embryos, which are monitored for a few days to check that they are growing normally.

In GCSE Biology, you learn that in vitro fertilisation (IVF) is a fertility treatment carried out outside the body. Eggs and sperm are combined in the laboratory, and selected embryos are transferred to the uterus.

Key Terms

IVF (in vitro fertilisation): A fertility treatment where eggs are fertilised by sperm outside the body and embryos are then placed in the uterus.
Embryo: An early stage of development that forms after fertilisation, before the foetus stage.
Implantation: The stage when an embryo attaches to the lining of the uterus and begins to grow there.

Frequently Asked Questions (Click to see answers)

What is IVF in GCSE Biology?

In GCSE Biology, IVF is described as a medical procedure in which eggs are collected from a woman, fertilised with sperm in a laboratory dish, and then embryos are placed into the uterus.

What are the main stages of IVF treatment?

The main stages are hormone treatment to mature several eggs, egg collection, mixing eggs with sperm in the laboratory, culturing embryos, and transferring one or more embryos into the uterus.

What are the advantages and disadvantages of IVF?

IVF can help some infertile couples have children and can be combined with screening for genetic disorders. However, it is expensive, has no guaranteed success, and raises ethical concerns about spare embryos.

Edwards and Steptoe

Frank and Benny

They also succeeded in producing the first boy to be conceived by IVF, Alastair MacDonald, who was born in 1979

2 .

Name a hormone used in IVF treatment to stimulate eggs.

Thyroxine

Adrenaline

FSH

This stimulates the ovaries to produce egg cells

3 .

A hormone is a chemical messenger. Where do hormones travel?

In the urine

In the ovary

In the pituitary

In the blood

Hormones are chemical messengers that produce a change in their target cells

4 .

During IVF, where are the egg and sperm mixed?

Inside the vagina

Outside the body, in the lab

In a surrogate mother

Inside the uterus

During the 1980s, scientists improved the number of successful IVF fertilisations and these days it is much more reliable

5 .

Which of the following is a risk of IVF treatment?

Infection

Multiple pregnancy twins or triplets

Bleeding

Chest infection

Usually more than one embryo is implanted. Each one could develop into twins or triplets which can lead to complications during pregnancy

6 .

If a couple's baby is implanted into another woman, what is she known as?

A donor

A carrier

A surrogate

A biological mother

It is possible for a woman to give birth to another woman's child

7 .

Hormonal treatment of the mother to stimulate egg production can lead to what?

Painful, swollen ovaries

Infertility

No affect

Difficulty sleeping

The treatment puts great demands on the ovaries since many eggs are required in order for IVF to be successful

8 .

What is the most common reason for having IVF treatment?

No uterus

Too old

No partner

Egg tubes (fallopian tubes) damaged

Chlamydia infection is the leading cause of fallopian tube damage, hence infertility

9 .

What does ethical mean?

Cost

Social impact

Moral

Politics

With any artificial biological process like IVF, there is always a need to consider the ethics

10 .

What does IVF stand for?

In vivo fertilisation

In vitro fertilisation

Intra venous formulation

In vitro formulation

in vitro means in glass or in a test tube
