In Vitro Fertilisation

In Vitro Fertilisation (IVF) was developed to enable conception to occur in the laboratory, under controlled conditions. This is followed by culture of embryos in special culture dishes before transfer of the “best” embryo back into the uterus.

This type of treatment is best for women who have blocked or absent fallopian tubes, endometriosis, unexplained infertility or if the male partner has poor quality sperm.

The success rates per IVF treatment cycle are typically 25% to 45% depending on factors such as patient age.

IVF Procedure

For the IVF procedure the ovaries are stimulated with fertility drugs into producing more eggs (ideally 5-10) - normally only one egg is released per cycle. The idea is not to produce too many eggs as too many eggs in the ovaries (>15) often leads to poor egg quality and can place the woman’s health at risk because of a condition called ovarian hyperstimulation syndrome (OHS).  Assisted Conception Australia is committed to producing the appropriate number of eggs by judicious use of the injections, which stimulate the egg production.
After stimulation of the ovaries a number of ultrasound scans are performed over a two-week period, to determine the date for egg collection. When the date is right, the eggs are then located and collected under ultrasound while the woman is under anaesthesia.

The eggs are placed in a sterile culture dish, labelled with the patient’s name and date of birth, and placed in an incubator. If a fresh semen sample is to be used it has to be produced on the same day that the eggs are collected. Alternatively frozen semen can be thawed.

 Injections or vaginal gel, containing progesterone, can be taken Generally extra treatment either injections or vaginal gel are taken after embryo transfer to optimise the chance of the treatment cycle being successful. A pregnancy test can be taken in 2-3  weeks.
