Intracytoplasmic Sperm Injection (ICSI)
Intracytoplasmic sperm injection (ICSI) is the process where sperm is injected directly into an egg to fertilise it in an IVF procedure. In natural conception and traditional IVF, sperm swim to the egg, attach to the egg’s shell, and push through the shell to get inside the egg. Once inside, the sperm’s DNA mixes with the female’s DNA to create an embryo. This is the process of fertilisation. In some cases, the sperm cannot penetrate the egg’s shell, so ICSI is required to help the sperm get into the egg. The procedures that you will experience with ICSI are exactly the same as IVF. The only difference is that on the day of the egg retrieval, our highly trained embryologist will inject a single sperm into each mature egg.
Artificial Insemination (IUI)
Artificial Insemination, or Intrauterine insemination (IUI), is a fertility treatment that involves inserting washed sperm into the uterus. It is done at the time of ovulation to improve the chances of pregnancy. IUI can be used on its own or, more commonly, along with medication to increase the number of eggs being ovulated. On the day of the IUI procedure, a semen sample is collected. Ideally within 30 minutes of it being produced an andrologist washes the semen and prepares it for IUI. The washed sperm is put into a thin plastic catheter which is then put into the woman’s uterus through her cervix. The sperm are then released.
Gamete Intro-Fallopian Transfer (GIFT)
Gamete Intro-Fallopian Transfer begins with traditional IVF treatment – with ovarian stimulation, monitoring and egg (or oocyte) collection. However, the difference between IVF and GIFT is that the collected egg and prepared sperm are then placed together in the woman’s fallopian tube, to allow for fertilisation with the body.
Frozen Embryo Transfer
Any excess healthy embryos from IVF treatment are usually frozen, in case more than one embryo transfer is needed to achieve a pregnancy, or you are trying to achieve a subsequent pregnancy. Freezing embryos – or cryopreservation – takes place for around 60% of all patients having IVF treatment, and frozen embryo transfers (FETs) account for many IVF births.
