IVF (In Vitro Fertilization)

What is IVF, in plain words?

IVF is a way of helping an egg and sperm meet when they're struggling to do so on their own. Instead of fertilization happening inside the fallopian tube, it happens in a lab dish. Once an embryo forms and grows for a few days, your doctor places it into the uterus — and from there, the pregnancy is exactly like any other.

If someone calls it a "test tube baby," they mean the same thing. It's an old nickname from 1978, when the world's first IVF baby, Louise Brown, was born. No test tube is actually used; embryos grow in shallow culture dishes inside carefully controlled incubators. In the decades since, IVF has grown from a medical first into an everyday treatment — more than 13 million babies have been born this way, with over half a million more arriving every year.

Who needs IVF?

IVF is a medically assisted path to parenthood, usually recommended when natural conception keeps hitting a wall. It isn't the first option for everyone — but for these situations, it's often the one that works:

• Blocked or damaged tubes (tubal factor): when the fallopian tubes are blocked or damaged, the egg and sperm simply can't meet. IVF skips the tubes entirely.
• Male-factor infertility: a low sperm count, weak movement (motility) or unusual shape (morphology). ICSI, a technique within IVF, can help here.
• Complex reproductive conditions: such as advanced endometriosis or a diminished ovarian reserve (fewer or lower-quality eggs).
• Unexplained infertility: when all the tests look normal but pregnancy still isn't happening, especially after a few IUI cycles.
• Building a family another way: supporting same-sex couples, single parents, and anyone using donor eggs, sperm or embryos.

Not sure which group you fall into? That's exactly what a first consultation is for — a proper look before anyone suggests a plan.

How does IVF work? The 10 steps

Every journey is a little different, but IVF generally follows the same 10-step path over about 4 to 6 weeks. Here's what actually happens, step by step, in plain language:

Is the IVF baby really mine?

Yes — when your own egg and your own sperm are used, the baby is 100% genetically yours. This is the worry couples carry quietly into treatment, so let's be completely clear: IVF changes where fertilization happens, not whose cells make the child. Your DNA is your baby's DNA.

To guard that promise, our labs use an electronic witnessing system. Every egg, every sperm sample and every embryo is tagged and tracked at each step, so the right cells always stay matched to the right couple. It's a quiet piece of technology, but it answers one of the deepest fears in IVF — and we think that peace of mind should come as standard, not as an upgrade.

Is IVF safe?

IVF has a track record stretching back over four decades, and today it's one of the most closely studied treatments in medicine. Since the first IVF baby in 1978, more than 13 million children have been born this way worldwide — that scale is exactly why the process is so well understood.

Modern care has made it safer still. Better protocols have made severe OHSS (ovarian hyperstimulation, an over-response to the injections) much less common than it used to be. And moving to single-embryo transfer has sharply cut the risk of twin and triplet pregnancies — the UK regulator's data shows multiple births falling from around 1 in 4 in the 1990s to well under 1 in 10 today. That matters, because multiple pregnancies carry more risk for both mother and babies.

That said, no medical procedure is risk-free, and we won't pretend otherwise. There are small, manageable risks, and the honest thing is to talk them through with you before you start — which is exactly what your specialist will do at your consultation.

How successful is IVF?

IVF works for a great many couples — but the honest answer is that success depends heavily on age and the reason behind the infertility, and no one can promise a baby. Anyone who guarantees success isn't being straight with you.

Here's an honest benchmark. Using a couple's own eggs, the UK's fertility regulator (HFEA) reports the birth rate per embryo transferred is highest for women under 35 — roughly 1 in 3 — and it falls steadily with age, down to around 1 in 20 by the early-to-mid forties. Those are population averages, not your personal odds, and your chance can be higher or lower depending on your diagnosis, egg and sperm quality, and other factors. Many couples also improve their overall odds across more than one cycle, or by using frozen embryos.

What we can promise is a truthful, personalised picture: after your tests, your specialist will explain what your realistic chance looks like — no inflated numbers, no pressure.
