In vitro fertilization (IVF)
IVF is a type of fertility treatment where fertilization takes place outside the body. It’s suitable for people with a wide range of fertility issues and is one of the most commonly used and successful treatments available for many people. This page introduces you to how IVF works, the risks, IVF Cost in Pakistan, and success rates.
What is IVF?
IVF is a common treatment for people who are unable to conceive naturally.
Usually in IVF, the woman has medicines (fertility hormones) to stimulate the ovaries to produce several eggs. The eggs are then collected and mixed with sperm in a laboratory.
IVF is carried out when the sperm quality is considered to be ‘normal’ if there are issues with the sperm quality such as low motility or numbers, a procedure called intracytoplasmic sperm injection (ICSI) may instead be used – this is where a single sperm is injected into the egg by an embryologist
If fertilization is successful, the embryos are allowed to develop for between two and six days. This helps the embryologist to select the strongest embryo, which is then transferred back to the woman’s womb to hopefully continue to a successful birth.
Often several good-quality embryos will be created. In these cases, it’s normally best practice to freeze the remaining embryos because putting two embryos back in the womb increases your chance of having twins or triplets, which carries health risks. You can use your frozen embryos later on if your first cycle is unsuccessful or you want to try for another baby.
How safe is IVF?
IVF is generally very safe and most who have it experience no problems with their health or pregnancy. However, there are some risks to be aware of, which include:
Ovarian hyperstimulation syndrome (a severe reaction to fertility drugs)
Having multiple pregnancies or births (twins, triplets, or more), can cause serious health problems to both mum and babies
Having an ectopic pregnancy
Possible birth defects (these are rare and research is still ongoing).
It’s very important you understand all the risks of IVF and know when to spot the symptoms of something serious.

It depends on where you live as decisions around who can have IVF on the NHS are made locally rather than nationally. Talk to your GP about what’s available in your area.
How long does IVF take?
Before you have IVF, you’ll need various appointments with your doctor and/or tests and investigations, so be prepared for it to take some time. It’s not something to take lightly, so take your time to think things through, ask questions, and make sure you’re clear on what’s involved and what to expect.
IVF is referred to as a ‘cycle’ of treatment as it involves a number of stages: suppressing natural hormone production, hormone treatment to boost egg supply, egg collection, mixing the eggs and sperm, and finally, embryo transfer (more information on the process below). How long it takes depends on your recommended treatment.
For most people, one cycle of IVF will take between four and six weeks. However, for medical reasons, some women won’t have the first stage of treatment (suppressing hormone production) which brings their treatment time down to around three weeks. Your doctor will advise you on the most appropriate treatment for you.
How successful is IVF?
As with Fertility Centre in Pakistan, how successful IVF will be depends on the woman’s age and the cause of infertility.

When we had our first cycle of IVF we just assumed it would work. You read all those ‘miracle baby’ stories in the media but you rarely hear about the people who weren’t successful.
