HISTORY OF IVF
IVF first achieved with rabbits in 1959
IVF with human gametes - pioneered by Robert Edwards and Patrick Steptoe during the 1960s and 1970s
On July 25, 1978, the first baby was born through in vitro fertilisation –Louise Brown
In 2010, Robert Edwards was awarded the Nobel Prize in Medicine "for the development of in vitro fertilisation"

OOCYTE RETRIEVAL
The oocytes are retrieved from the woman by using an ultrasound-guided needle to puncture the follicles and collect the oocytes. Thus, enabling fertilisation outside the body.

SPERM PREPARATION
During sperm preparation, the most viable sperm cells are selected and supported. An optimal sperm preparation should result in a sufficient number of motile, morphologically normal and functional spermatozoa with maintained viability.

FERTILISATION
TWO METHODS
ICSICONVENTIONAL IVF
Sperm and oocytes are placed together in a dish with media. The sperm find their way to the oocyte and fertilisaton takes place.
Sperm needs to be injected into the oocyte for fertilisation to take place.

EMBRYO EVALUATION
Observe the embryos regularly and make accurate assessments whileminimising disturbance to avoid stress
Determine embryo genetic normality

EMBRYO TRANSFER
Embryos are transferred into the uterus after 2-5 days of in vitro culture

CRYOPRESERVATION
TWO METHODS
VitrificationSlow freezing
Cryopreservation enables good quality embryos to be cryopreserved for future use. The embryos are maintained in liquid nitrogen for long-term storage
