I've just found this in a book i got given when doing IVF its called infertility The HFEA guide 2007/08. (Theres a website
www.hfea.gov.uk)
This is what it says:
Drugs and Surgery
A combination of fertility drugs and surgery are often used to kick start treatment either before or during IVF
For Women
If you aren't ovulating (producing and releasing an egg each month) at all, or only sometimes, fertility drugs - which trigger egg production in much the same way as your bodys own hormones - can help. This is known as ovulation induction. You may get pregnant using fertility drugs alone, but they are more often used with other treatments such as intrauterine insemination (iui) and in vitro fertilisation (ivf). Read on for what to expect.
Ovulation-inducing drugs
Cloiphene citrate, usually known simply as Clomid, is the oldest and probably the most widely used fertility drug. Taken as a pill, it tells your brain that you are not producing enough oestrogen, which indirectly stimulates your ovaries into producing eggs.
What for: Straightforward ovulation failure in woman under 40.
Possible side effects hot flushes, mood swings, nausea, breast tenderness, insomnia, increased urination, heavy periods, spot breakouts, weight gain. Some experts think your risk of ovarian cancer may increase slightly if you take it for more than a year.
Pituitary stimulators
Pulsed gonadotrophin-releasing hormone (GnRH), such as Gonadorelin, kick starts the pituitary gland into action. A small battery operated pump usually worn on the upper arm injects pulses of the drug directly into your bloodstream (hence the term pulsed). This triggers egg production by mimicking your bodys production of a hormone produced by the pituitary.
What for: Ovulation failure resulting from a lack of the hormone GnRH
Prossible side effects Stomach pains, sickness and nausea, heavy periods and headaches
Ovary-stimulating hormones
Drugs containing folicle-stimulating hormone (FSH) and/or luteinising hormone (LH) stimulate the ovaries to produce eggs. These include Gonal-f, Puregon, Menogon, Menopur and Merional. They are injected into a muscle or under the skin by your doctor at the clinic, your GP or pratice nurse. Alternatively, you may be shown how to inject yourself at home. When the eggs are mature, you are given a single injection of the hormone chorionic gonadotrophin (hCG) to trigger the release of an egg.
What for: To simulate ovulation before treatment cycles, or if you have polycystic ovary syndrome (PCOS) and your ovaries are not responding to Clomid. They are also used for infertility caused by failure of the pituitary gland and in some cases of male infetility.
Possible saide effects Over stimulation of the ovaries, known as ovarian hyperstimulation syndrome (OHss), increased risk of multiple pregnancy when used for ovulation induction, allergic reactions and skin reactions.
During treatment your doctor will usually prescribe other drugs for you to take at various times to give them more control over your treatment cycle. These may include:
Cycle suppersing drugs
Drugs such as Goserelin and Burserelin copy the action of natural hormones that block the release of the two hormones controlling ovulation: FSH and LH. These are known as gonadotrophin releasing hormone (GnRH) analogues. You take them as a nasal spray or as a daily or mothly injection before, or at the same time as, fertility drugs.
What for: To stop the menstrual cycle.
Possible side effects hot flushes, night sweats, headaches, vaginal dryness, mood swings, changes in breast size, breakouts of spots, acne and sore muscles.
Drugs that maintain pregnancy
Progesterone for example Cyclogest, Gestone, Crinone or Progynova, can be taken after the injection pregnancy hormone hCG or on the day embryos are returned to the womb. You take them as vaginal suppository, a pill, gel or by injection into the buttock.
What for: to thicken the lining of the womb in preparation for nurturing a possible embryo.
Possible side effects Nausea, vomiting, swollen breasts.
Sorry for it being so long but have just type all what it said!!!
