Assisted Reproductive Technology Ivf Icsi

Overview

Assisted reproductive technology (ART) is a group of treatments that help people have a baby when they are having trouble getting pregnant naturally. The two most common types are IVF and ICSI. In IVF (in vitro fertilization), eggs are collected from the woman's ovaries and mixed with sperm in a laboratory to create embryos. In ICSI (intracytoplasmic sperm injection), a single sperm is injected directly into a single egg. Both are done outside the body, and a healthy embryo is then placed into the woman's uterus.

Yes. Infertility affects about 1 in 6 couples around the world. Many of these couples use ART to help them conceive.

ART is used by people of reproductive age, both women and men, who are trying to have a baby. It can also help single people and same-sex couples who need donor eggs, donor sperm, or donor embryos.

Symptoms

Common symptoms

• Irregular or absent menstrual periods
• Long or painful periods
• Pelvic pain or pain during sex
• A history of miscarriage or failed pregnancies
• No pregnancy after a year of regular unprotected sex

Symptoms in children

• Not applicable. ART is a treatment for adults who are trying to conceive.

Symptoms in older adults

• Not applicable in the same way. Age-related fertility decline can affect women over 35 and men over 40.

Causes

Main causes

• Blocked or damaged fallopian tubes, which prevent egg and sperm from meeting
• Problems with ovulation, such as polycystic ovary syndrome (PCOS) or hormone imbalances
• Male infertility, such as low sperm count, poor sperm movement, or abnormal sperm shape
• Endometriosis, a condition where tissue like the uterus lining grows outside the uterus
• Unexplained infertility, where no clear cause is found

Risk factors

• Woman's age over 35, because egg quality and quantity decline
• Man's age over 40, which can affect sperm health
• Smoking, heavy alcohol use, or drug misuse
• Being very overweight or very underweight
• Stress and poor sleep
• Certain medical conditions or past surgeries affecting the reproductive organs

When to see a doctor

See a doctor urgently if:

• If you have severe pain, heavy bleeding, or sudden shortness of breath during or after an ART cycle, seek emergency care immediately.
• If you have a fever, severe abdominal swelling, or fainting, contact your clinic or doctor the same day.

Book a routine appointment if:

• If you are under 35 and have been trying to conceive for 12 months without success, schedule a fertility check.
• If you are over 35, it is reasonable to see a doctor after 6 months of trying.
• If you have known reproductive issues, a history of miscarriages, or painful conditions like endometriosis, talk to your GP or a fertility specialist sooner.

Diagnosis

Before starting ART, both partners will have a fertility evaluation. A GP or fertility specialist will ask about medical history, any treatments you have had, and how long you have been trying. They will also do physical exams and order tests.

Tests that may be done

• Blood tests to check hormone levels for both women and men
• Ultrasound scans to look at the uterus, ovaries, and fallopian tubes
• A semen analysis to assess sperm count, movement, and shape
• A test for blocked fallopian tubes, such as an X-ray with dye (hysterosalpingogram)
• In some cases, genetic screening or a biopsy of the womb lining

What to expect at your appointment

Fertility testing usually takes several weeks. Some tests need to be done at specific times in your menstrual cycle. You may need to stop certain medicines before tests, but your doctor will guide you. The results help you understand your options, including whether IVF or ICSI is right for you.

Treatment

ART covers a range of treatments. IVF is the most common. In a typical IVF cycle, the ovaries are stimulated naturally or with medicines to produce multiple eggs. The eggs are collected through a minor procedure, then fertilized with sperm in a lab. After a few days, one or two healthy embryos are placed into the uterus. ICSI is a version of IVF used when sperm are the problem. It involves injecting a single sperm directly into each egg to improve fertilization.

Self-care at home

• Maintain a healthy weight, because obesity or being underweight can affect success.
• Avoid smoking, heavy drinking, and recreational drugs.
• Find healthy ways to manage stress, such as talking to a friend, writing, or relaxation exercises.
• Follow your doctor's instructions about exercise and rest during and after treatment.

Medical treatments

ART procedures are done in a fertility clinic. Medicines may be used to stimulate the ovaries, prepare the uterus, or support the early stages of pregnancy. These are often given as injections or pills, but never take any fertility medicine on your own. Always ask your doctor or nurse about the medicines they recommend, how to use them, and any side effects. The clinic will explain the exact steps of your treatment cycle.

When is surgery considered?

Surgery is sometimes needed before ART. For example, a doctor may remove fibroids, treat endometriosis, or repair blocked fallopian tubes. For ICSI, sperm can be collected directly from the testicles with a needle in a minor surgical procedure. You will be given pain relief and sedation if needed.

Living with this condition

Going through ART can be emotionally and physically demanding. Planning your appointments, taking medicines, and coping with results can be stressful. Try to keep a routine that includes sleep, gentle activity, and time for yourself. It is okay to set boundaries with friends and family about what you want to share.

Lifestyle tips

• Eat a balanced diet rich in fruits, vegetables, whole grains, and lean proteins.
• Get regular moderate exercise, like walking or swimming, to boost mood and overall health.
• Limit caffeine and avoid energy drinks.
• If you are overweight, losing a small amount (even 5–10%) can improve fertility and treatment success.

Diet and exercise

There is no 'special' diet that guarantees success, but eating well supports your body. A Mediterranean-style diet with plenty of vegetables, fish, and healthy fats is often recommended. Doing 30 minutes of moderate exercise most days can help, but avoid very intense workouts that might interfere with your cycle.

Mental health and emotional wellbeing

Infertility and ART can bring feelings of sadness, anxiety, anger, and isolation. These feelings are normal. If you feel overwhelmed, please talk to your healthcare team. They can refer you to a counselor who understands fertility issues. You can also reach out to mental health support services in your area.

Prevention

Not all causes of infertility can be prevented, but you can improve your overall health. Avoiding smoking, limiting alcohol, keeping a healthy weight, and getting treated early for infections can reduce your risk. If you are planning to start a family later in life, you may discuss fertility preservation options like egg or sperm freezing with your doctor.

Vaccines

There are no vaccines to prevent infertility or to guarantee ART success. However, staying up to date with recommended vaccines, such as measles, mumps, rubella (MMR) and chickenpox (varicella), is important before pregnancy. Ask your doctor which vaccines you may need.

Screening programmes

Routine fertility screening is not needed for everyone. But if you are thinking about pregnancy and have risk factors, a doctor may offer blood tests for hormone levels, infections, or genetic conditions. Early screening can help you make informed choices.

Complications

If left untreated

• If you do not seek help for infertility, it can lead to ongoing emotional distress and feelings of loss.
• Some underlying health conditions, such as polycystic ovary syndrome or hormone problems, may go unnoticed and affect your overall health.
• For men, untreated infections or hormone issues could affect sperm health and general well-being.

Long-term outlook

Many couples and individuals do become parents with the help of ART. Success rates have improved steadily, and experts continue to find safer and more effective methods. Even if the first cycle does not work, there are often other options to try. With good support and the right team, there is genuine hope.
