The process involves monitoring and stimulating a woman 's ovulatory process, removing an ovum or ova from the woman 's ovaries and letting sperm fertilise them in a liquid in a laboratory. The fertilised egg is cultured for 2–6 days in a growth medium and is then implanted in the same or another woman 's uterus, with the intention of establishing a successful pregnancy.

Through this needle follicles can be aspirated, and the follicular fluid is passed to an embryologist to identify ova. It is common to remove between ten and thirty eggs. The retrieval procedure usually takes between 20 to 40 minutes, depending on the number of mature follicles, and is usually done under conscious sedation or general anaesthesia.
Egg and sperm preparation
In the laboratory, the identified eggs are stripped of surrounding cells and prepared for fertilisation. An oocyte selection may be performed prior to fertilisation to select eggs with optimal chances of successful pregnancy. In the meantime, semen is prepared for fertilisation by removing inactive cells and seminal fluid in a process called sperm washing. If semen is being provided by a sperm donor, it will usually have been prepared for treatment before being frozen and quarantined, and it will be thawed ready for use.
