Ivf

Overview

IVF stands for in vitro fertilisation. 'In vitro' means 'in glass' — in a lab, outside the body. IVF is a fertility treatment. Eggs are collected from the ovaries, mixed with sperm in a laboratory so an embryo can form, and then one embryo (sometimes more) is placed inside the womb to grow. It is used when a person or couple is having trouble getting pregnant, or when there is a reason pregnancy is unlikely to happen naturally. IVF is a treatment, not an illness — you are not 'sick' because you need it.

Yes. Fertility problems are common — roughly 1 in 7 couples have trouble conceiving. IVF is one of the most widely used fertility treatments worldwide, and millions of babies have been born through it. If you are considering IVF, you are far from alone.

IVF is offered to adults of reproductive age who want a child and are not conceiving naturally. That includes different-sex couples, same-sex couples, and single people using donor sperm. Common reasons include blocked or damaged fallopian tubes (the tubes that carry the egg), endometriosis (tissue like the womb lining growing elsewhere), low sperm count or sperm that move poorly, ovulation problems, and 'unexplained infertility' — where tests are normal but pregnancy has not happened. Some people use IVF to avoid passing on a serious inherited condition, or to store eggs or embryos before medical treatment such as cancer therapy.

Symptoms

Common symptoms

• IVF is not an illness, so it has no 'symptoms' in the usual sense. What you feel comes from the hormone medicines and the procedures.
• Bloating, a full or heavy feeling in the lower belly, and mild cramping during the weeks of ovary-stimulating medicine.
• Mood swings, tearfulness, irritability, headaches, and tiredness — these are very common and usually settle.
• Small bruises or soreness where injections were given.
• Mild to moderate period-like pain or spotting for a day or two after egg collection.
• Light cramping or spotting in the days after the embryo transfer (when the embryo is placed in the womb).
• Tender breasts and a bloated feeling in the two-week wait before the pregnancy test — these can be caused by the medicines, so they do not reliably tell you whether the cycle worked.

Symptoms in children

• IVF is not a childhood condition. Children born through IVF are not 'IVF patients' — they are simply children, and most are healthy.
• Some children born through IVF may be followed up by their clinic for a short time as part of routine monitoring, but this does not mean anything is wrong.
• If you are a parent explaining IVF to a child, keep it simple and positive: 'A doctor helped us have you, and we were very happy.'

Symptoms in older adults

• IVF is not relevant to most older adults, as natural fertility ends with menopause.
• People in their late 30s and 40s may still pursue IVF, often with donor eggs. Success rates fall steadily with age, and clinics discuss this openly.
• Older adults sometimes support a grown child through IVF. Being a calm, listening presence is genuinely helpful.

Causes

Main causes

• Damaged or blocked fallopian tubes, so the egg and sperm cannot meet naturally.
• Endometriosis, which can affect the ovaries, tubes, and the environment in the pelvis.
• Sperm problems — low numbers, poor movement, or unusual shape.
• Ovulation problems such as polycystic ovary syndrome (PCOS), where eggs are released irregularly or not at all.
• Unexplained infertility — all tests look normal, but pregnancy has not happened after a year of trying.
• Age-related decline in egg number and quality.
• A need to avoid passing on an inherited condition to a child, using embryo testing before transfer.
• Fertility preservation — storing eggs or embryos before treatment such as chemotherapy or surgery.
• Being in a same-sex relationship or being single and wanting a child, using donor sperm.

Risk factors

• Age — fertility in women falls more steeply after the mid-30s, and IVF success rates fall with it.
• Smoking, in either partner, which lowers success rates.
• Being significantly overweight or underweight, which can affect ovulation and treatment response.
• Past pelvic infection or sexually transmitted infections, which can scar the tubes.
• Previous surgery on the ovaries, tubes, or womb.
• Heavy alcohol use in either partner.
• Conditions such as PCOS, thyroid problems, or diabetes that are not well controlled.
• Long delay before seeking help — time matters, especially over age 35.

When to see a doctor

See a doctor urgently if:

• Severe or worsening belly pain, marked swelling, breathlessness, or feeling faint at any point during or after IVF treatment.
• Fever, shivering, or feeling very unwell after egg collection.
• Heavy bleeding with pain or dizziness.
• Chest pain, sudden breathlessness, or coughing up blood.

Book a routine appointment if:

• You have been trying to conceive for a year without success (or six months if you are 35 or older).
• Your periods are very irregular, very painful, or have stopped.
• You have a known condition such as endometriosis, PCOS, or a past pelvic infection.
• Either partner has had cancer treatment, pelvic surgery, or a diagnosed fertility problem.
• You are single or in a same-sex relationship and want to explore your options.
• You feel low, anxious, or overwhelmed about fertility — this is a good reason to see your doctor on its own.

Diagnosis

IVF is not something you are 'diagnosed' with — it is a treatment you are offered after a fertility assessment. Your doctor or fertility clinic will take a detailed history from both partners, including how long you have been trying, your periods, past infections, surgery, and family history. They will then arrange tests to work out the likely cause and which treatment is most suitable. If IVF is recommended, the clinic will also check you are well enough for treatment and explain the process, the risks, and the realistic chance of success for your situation.

Tests that may be done

• Blood tests to check hormone levels, including tests that show how well the ovaries are likely to respond to treatment and whether you are ovulating.
• A semen analysis for the male partner — a sample is checked for sperm number, movement, and shape.
• A pelvic ultrasound scan, an internal scan using sound waves, to look at the ovaries and womb.
• A test to check whether the fallopian tubes are open, sometimes using a dye and X-ray or a scan.
• Screening blood tests for infections such as HIV and hepatitis, which is routine before fertility treatment.
• Checks on immunity to rubella (German measles) and general health checks such as thyroid function.
• Sometimes a womb-lining sample, an X-ray of the womb, or genetic tests, depending on your history.
• Screening for both partners for any inherited conditions if embryo testing is planned.

What to expect at your appointment

The assessment usually takes a few weeks because tests are spread across your cycle. You will normally have an appointment to discuss results and options. Ask for the numbers in your own case — chance of a live birth per cycle, and how that changes with your age and any second cycle. It is fine to take notes, bring someone with you, and ask the same question twice. You should be given written information and time to decide. You can always ask for a second opinion or a break to think.

Treatment

A typical IVF cycle has several stages. First, your ovaries are 'quietened' (down-regulated) so your clinic can control the timing. Then you take hormone medicines, usually as small injections, to help several eggs grow at once. The clinic checks your progress with ultrasound scans and blood tests. When the eggs are ready, you have a 'trigger' injection to help them mature, and about a day and a half later the eggs are collected through a fine needle, usually with sedation. In the lab, eggs and sperm are combined so embryos can form. One embryo (sometimes two, depending on your situation) is then placed in the womb using a thin tube. About two weeks later, a pregnancy test is done. Any good-quality embryos left over can often be frozen for later use.

Self-care at home

• Follow your clinic's instructions exactly about timing — hormone medicines work best when given at consistent times.
• Ask your clinic to show you how to do the injections and where to store the medicines; most people find it easier after one practice run.
• Keep a simple diary of medicines, appointments, and any symptoms you notice — it helps you answer your clinic's questions.
• Stay gently active. Walking and normal daily activity are fine; check with your clinic about strenuous exercise during ovary stimulation, when the ovaries are enlarged.
• Drink enough water and eat regular meals, especially if you feel bloated.
• Take time off for key appointments and, if you can, plan a lighter week around egg collection.
• Avoid smoking, recreational drugs, and heavy drinking during treatment.
• Ask about counselling before you start — most clinics offer it, and it is not a sign anything is wrong.
• Keep your questions in a notebook or on your phone so you do not forget them at appointments.

Medical treatments

IVF uses a set of hormone medicines to control your cycle, stimulate the ovaries to produce several eggs, trigger egg maturation at the right moment, and support the lining of the womb after transfer. Some people also use medicines to prevent the ovaries over-responding, or to help with pain during egg collection. Your clinic will explain exactly what each medicine is for, and will tailor the plan to your age, test results, and any previous response. Because medicines and protocols differ between clinics and countries, ask your own team rather than relying on what worked for someone else. Never take fertility medicines that were not prescribed for you.

When is surgery considered?

IVF itself is not surgery, but two parts involve procedures. Egg collection is a short procedure, usually with sedation or a light anaesthetic, using a fine needle guided by ultrasound. Embryo transfer is a simple procedure, a bit like a smear test, and usually needs no anaesthetic. Surgery is sometimes needed for complications — for example, a twisted ovary, severe ovarian hyperstimulation, an ectopic pregnancy, or infection. Some men need a small operation to collect sperm directly from the testicle. Your team will explain any procedure, its risks, and what recovery involves before you agree to it.

Living with this condition

IVF is a treatment you go through, not a long-term condition. Day to day, the main tasks are timing medicines, attending scans, and managing your energy. Appointment times can be early or change at short notice, so it helps to tell your employer or school you may need flexibility. Many people keep treatment private and plan simple cover stories, or tell one trusted person. Keep some structure to your week — normal routines, work, and gentle social contact all help. Try to limit how much you read online late at night, and get information from your clinic first.

Lifestyle tips

• Stop smoking if you can — this is the single biggest lifestyle change that helps fertility for both partners.
• Cut out alcohol, or keep it very low, during treatment.
• Aim for a healthy weight; even modest changes can improve ovulation and response to treatment.
• Keep active with gentle, regular movement such as walking, swimming, or yoga.
• Protect your sleep — tiredness from medicines is real, and rest is part of the plan.
• Reduce caffeine to a moderate level while trying to conceive.
• Avoid saunas, hot tubs, and long hot baths if you are the male partner, as heat can affect sperm.
• Plan something to look forward to during the two-week wait, so the time is not only about waiting.

Diet and exercise

Eat regular, balanced meals with plenty of vegetables, fruit, whole grains, and protein, and drink enough water — this helps you feel steadier when hormones make you bloated or tired. Your care team may suggest a vitamin supplement containing folic acid before conception and in early pregnancy, and possibly vitamin D; ask your clinic or pharmacist what they advise for you. Gentle exercise is encouraged. During ovary stimulation, when the ovaries are enlarged, avoid high-impact or twisting exercise, heavy lifting, and contact sports, because the ovaries can twist or rupture. After embryo transfer, most clinics advise normal gentle activity rather than strict bed rest.

Mental health and emotional wellbeing

IVF can be an emotional rollercoaster. The highs of a scan with good news and the lows of a negative test can come within weeks. Waiting is often the hardest part, and many people feel anxiety, low mood, grief, or strain in their relationships. These feelings are normal and do not mean you are failing. It is okay to say no to baby showers or to ask for space. Talk to your clinic about counselling — it is a routine part of fertility care. If you ever have thoughts of harming yourself, or feel you cannot cope, please contact your local emergency number or a crisis support service in your country straight away. You deserve support, and help is available.

Prevention

You cannot always prevent needing IVF, and needing it is not your fault. But some causes of infertility can be reduced. Avoiding sexually transmitted infections and getting them treated promptly lowers the risk of scarred tubes. Not smoking, keeping a healthy weight, limiting alcohol, and managing conditions such as diabetes and thyroid problems all help. Seeking help early matters, especially if you are 35 or older, because fertility declines with age. If you are having IVF, you can also reduce the chance of complications by following your clinic's monitoring schedule, reporting symptoms early, and discussing how many embryos to transfer — single embryo transfer greatly lowers the risk of twins, which carry more risks for mother and babies.

Vaccines

There is no vaccine for infertility. Vaccination does matter around pregnancy: your clinic will usually check that you are protected against rubella (German measles) before treatment, and may advise a flu vaccine and other routine vaccines in pregnancy. Ask your doctor which vaccinations you need and when — some are best given before conception rather than during pregnancy.

Screening programmes

Before IVF, screening for infections such as HIV and hepatitis is routine for both partners, along with checks on immunity and general health. During ovarian stimulation, regular ultrasound scans and blood tests screen for over-response, so the dose can be adjusted early. In pregnancy after IVF, you will be offered the usual antenatal screening tests, and your pregnancy will often be monitored a little more closely, especially if you are older or expecting twins.

Complications

If left untreated

• Not having IVF is a valid choice; 'untreated' infertility does not harm your physical health, but it can bring sadness, grief, and strain on relationships, so support matters.
• Some underlying causes do need attention in their own right — for example, untreated infection, thyroid disease, or very heavy periods.
• During IVF, ovarian hyperstimulation syndrome (OHSS) is the most important complication: the ovaries over-respond, causing bloating, pain, and in severe cases breathing problems or clots. Monitoring catches most cases early.
• Multiple pregnancy (twins or more) is more likely with IVF and carries higher risks of premature birth and high blood pressure in pregnancy.
• Ectopic pregnancy, where the embryo grows outside the womb, is slightly more common after IVF and needs urgent treatment.
• Egg collection carries small risks of infection, bleeding, or a twisted ovary.
• The emotional strain of cycles that do not work should not be underestimated, and counselling helps.

Long-term outlook

The outlook is genuinely hopeful, even if it does not feel that way today. IVF success depends mostly on the woman's age and the reason for infertility, and clinics will give you realistic figures for your own case. Many people have a baby after one cycle; others need two or three, and some move on to donor eggs or sperm, or choose other paths such as adoption. It is also okay to decide to stop. Whatever happens, needing help to build a family is common, and you deserve clear information, kindness, and support at every step.
