I know its going to be to do with things like IVF, but does it include issues such as cloning as well? I have to write an essay on the the bio-ethics of assisted fertilisation, but having searched on the internet i've only found really complex articles that i don't understand! thanks for any help.

The concept of IVF is very simple...

You just fertilise some eggs with sperm in a lab...

You allow them to develop to a blastocyst (takes a few days as the cells divide)...

You inject them in the uterus (womb) and hopefully one of them will become embedded in the endometrium (womb lining) and will develop into a baby...

It generally isn't that successful, which is why women have to have multiple cycles at IVF...

Btw, I wouldn't mention cloning, I don't see how it's related to IVF...

As for ethics - should women have IVF cycles free on the NHS? That is an issue you should mention...

Farmers do assisted fertilisation...

They like get sperm best male cow and eggs from the best female cow... make embryos... and then place the embryos in all of the female cows...

Actually, I suppose you could include this... and you could say that IVF may lead to the development of cloning... If I was personally doing this essay, I'd find out the laws on relating to fertilisation and new developments on fertilisation techaniques... remember what is ethical tends to just be what the law says is ethical...

There are quite a few techniques known as 'Assisted Reproductive Technologies' (ART). I had to write an essay on this in my first year and so have cut and paste a few relevant points for you.

Intra Uterine Insemination (IUI)
Sperm is injected using a catheter transvaginally directly into the uterine cavity. The procedure is normally carried out to coincide with ovulation and overcomes cervical problems that a woman may have preventing the normal passage of sperm through the cervix.

In Vitro Fertilisation (IVF)
As described by Sir Revenged.

Gamete Intrafallopian Transfer (GIFT)
Uses the same transvaginal ultrasound aspiration technique as IVF to collect a number of mature ova. Approximately four ova are combined with sperm from the father in a catheter and transferred to the fallopian tube via a procedure known as laparoscopy. GIFT is a suitable technique for women whose infertility is caused by cervical or immunological problems and mild endometrosis. As this technique ensures that both sperm and ova are in close proximity within the fallopian tube, it is also a reasonable method for moderate male infertility (where the sperm motility is low and would not naturally reach the fallopian tubes).

Intracytoplasmic sperm injection (ICSI)
For cases of complete male infertility. Involves injecting a single sperm cell directly through the egg membrane into the cytoplasm. The embryo is then implanted into the uterus using normal IVF methods. As the technique only involves a single sperm cell, it is a viable option for all infertile males as sperm can be extracted from the testes by needle under anaesthetic (epididymal sperm aspiration).

I hope some of that is of use to you

I like how scientifically you describe a woman being injecting with sperm...

lol...

Just spout out a load of scientific/medical terms and you're sorted lol :p:

Anyway, stop highjacking the thread - I hate highjackers! :p:
