Thorough investigations and individualised treatment is essential to achieving best possible fertility outcomes.


In vitro fertilisation (IVF ) is the most advanced treatment option used to treat female and male infertility.

IVF is also offered to couples who are known to carry a genetic disorder and wish to avoid having a child affected by the disease. Embryos created through an IVF process can be examined for the presence of the gene in question and only healthy or unaffected embryos will be then transferred back into the uterus.

During the IVF treatment cycle, women’s ovaries are stimulated to grow multiple follicles during a process called ovarian stimulation. This process is carefully monitored through a series of blood tests and ultrasound examinations.

Egg collection is undertaken under anaesthetic in hospital and takes approximately 15 minutes. All visible follicles will be aspirated through the vaginal wall using an ultrasound-guided needle. The follicle fluid is immediately passed to the scientist and examined for the presence of eggs. Not all follicles will contain eggs and this is a normal finding.

I will know how many eggs were collected before you wake up and I will write that number on the back of your hand.

When you wake up, you should experience very little or no discomfort. If you are experiencing severe pain, you must notify me immediately.

I will be calling you the next morning to let you know how many eggs are fertilised. All fertilised eggs will be placed in a special environment called a culture medium and will be referred to as embryos from that point on. These embryos remain in culture for 3-5 days before being transferred back into the uterus.

Excess embryos can be frozen and used in future treatment cycles.

ICSI – Intracytoplasmic Sperm Injection

This technique involves injecting sperm into eggs obtained through the process of ovarian stimulation as outlined above. It is usually necessary when sperm is abnormal and therefore loses its natural capacity to fertilise the egg spontaneously. Abnormalities can include a very low count, a high percentage of abnormal forms, inadequate movement, or where a high degree of DNA damage is present in the sperm.
