In vitro fertilisation (IVF) /
Intracytoplasmic sperm injection (ICSI)

IVF – in vitro fertilisation (literally, fertilising in glass i.e. in a laboratory)
ICSI – intracytoplasmic sperm injection (literally, injecting a sperm directly into the egg cell)

IVF

IVF is a term many of us are familiar with, but it actually covers quite a broad range of procedures. IVF refers to any procedure when an egg is fertilised in a laboratory rather than in the uterus.

This can be done in a few different ways:

Standard IVF
This involves taking ovary-stimulating hormonal medications, to encourage the development of several eggs that can be collected for freezing or fertilisation.
Higher success rates
Higher chance of side effects from treatment
Natural cycle IVF
This means not taking the ovary-stimulating hormonal medications, and collecting the single egg that’s released naturally in your normal cycle. This may be an option if you cannot or do not want to take these medications. However, success rates tend to be lower and not many fertility clinics will offer this.
Lower success rates
Lower chance of side effects from treatment
Mild stimulation IVF
This means taking the ovary-stimulating hormone medications but at either a lower dose or over a shorter time, like a half-way house between standard and natural cycle IVF.
Success rates lower than standard, higher than natural
Side effect risk lower than standard, higher than natural
In vitro maturation (IVM):
This involves collecting eggs before they are fully matured, and allowing them to develop further in the lab. This is a relatively new technique and success rates aren’t yet established. IVM may not be available in all clinics.

ICSI

When you want to use frozen eggs to try for a baby, they will need to be fertilised in the laboratory with an IVF technique called intracytoplasmic sperm injection, or ICSI.

The sperm used can be from a donor or a male partner. Donor sperm can also used for male-female couples where the male partner has a low sperm count or an issue with sperm quality.

With intracytoplasmic sperm injection (ICSI), a single sperm is injected straight into the egg cell. This fertilises the egg and prompts it to start dividing and developing into an embryo. ICSI has a high rate of fertilisation, as very little is left to chance, but the chances of a live birth from any given fertilised egg are around the same as for standard IVF.

In ICSI, a single sperm is injected straight into the egg cell. This fertilises the egg and prompts it to start dividing and developing into an embryo. ICSI has a high rate of fertilisation, as very little is left to chance, but the chances of a live birth from any given fertilised egg are around the same as for standard IVF.

ICSI is needed for frozen eggs, as the freezing process can harden the outer shell and make it more difficult for a sperm to get in to fertilise it.
 
Just as with everything related to fertility, there are no guarantees with IVF or ICSI. Doctors recommend that if one cycle doesn’t work, you wait a few months to recover before trying another cycle or exploring another route such as using donor sperm.
