In Vitro Fertilisation (IVF)
During the IVF process, the woman’s eggs are removed during a small surgical procedure and fertilised in a laboratory using a specimen of sperm from the woman’s partner, or donor sperm if necessary. The fertilised egg, called an embryo, is next surgically implanted into the uterus (womb) of the woman.
The IVF process:
- The woman is given fertility drugs (usually by injection) to stimulate egg production.
- Egg production is monitored with a vaginal ultrasound scan.
- The eggs are then collected when a surgeon passes a fine needle through the vagina and into the ovaries. This is usually carried out under a mild sedation or general anaesthetic. Nine or 10 eggs on average are collected.
- A sperm sample is taken from the husband or sperm from a donor is used.
- The sperm and eggs are mixed together in a laboratory; any eggs that become fertilised are called embryos.
- The woman is given progesterone, which helps thicken the lining of the uterus and prepares it for pregnancy.
- Next, one or two of the most viable embryos are collected and placed, through the vagina, into the uterus with a tiny catheter (this may rise to three embryos if the woman is over 40). This happens around two to three days after the eggs have been collected and fertilised.
- Two to three weeks later, an ultrasound scan is used to find out if the procedure has resulted in a successful pregnancy.
