Is IVF Painful? The Injections Are Usually Manageable. The Waiting Is Harder.
Last week, a patient sat opposite me clutching the information sheet for her IVF cycle. She had read about injections, egg retrieval, vaginal scans and embryo transfer. Her question was simple: “Doctor, will it hurt?”
My honest answer was: IVF is usually uncomfortable rather than severely painful, but some parts can hurt, and every woman experiences them differently. The injections are generally brief. The ultrasound scans may feel awkward or uncomfortable. Egg retrieval is performed under sedation or anaesthesia, so most patients do not feel the procedure itself. The emotional pain—the waiting, uncertainty and fear of failure—can be harder than the physical discomfort.
I do not tell patients that IVF is painless. That would be dishonest. I also do not want them to imagine that they are signing up for an ordeal involving unbearable pain every day. Most women get through the physical part with fewer problems than they feared. What they often underestimate is how much planning, patience and emotional energy the treatment demands.
Why the fear of IVF pain becomes so large
Patients rarely hear about IVF as one continuous experience. They hear isolated words: injections, stimulation, egg collection, anaesthesia, embryo transfer. Each word acquires a frightening meaning when it is encountered on the internet or in a conversation with someone who had a difficult cycle.
A woman may have never given herself an injection before. She may have seen a large needle used for blood collection and assume that IVF injections feel the same. She may have heard that eggs are “removed” and imagine a surgical procedure with a long recovery. Another patient may have had a painful experience at a different clinic and describe it vividly to a friend.
All of this creates confusion. IVF is not one procedure. It is a sequence of several steps, and the sensation at each step is different. I find that patients feel calmer when I describe the cycle in the same order in which it will happen, without pretending that every patient will have the same experience.
Here is what I usually explain.
Is IVF painful at each stage?
| Stage | What happens | What it may feel like | How long discomfort usually lasts |
|---|---|---|---|
| Baseline assessment | Blood tests and transvaginal ultrasound | Brief needle prick; pressure or awkwardness during the scan | Minutes |
| Ovarian stimulation | Daily hormone injections | Small sting, bruising, bloating, heaviness or mood changes | Several days, varying by patient |
| Monitoring | Repeat scans and blood tests | Usually mild discomfort or pressure | Minutes at each visit |
| Trigger injection | Final injection to mature the eggs | Similar to the stimulation injections | Brief |
| Egg retrieval | Eggs collected through the vagina using an ultrasound-guided needle | Usually no pain during the procedure because of sedation or anaesthesia; cramps afterwards are possible | Hours to a day or two for most patients |
| Embryo transfer | Embryo placed in the uterus through a thin catheter | Usually similar to a Pap smear or cervical examination; some women feel cramping | Usually brief |
This table is a guide, not a promise. Pain is subjective. A woman who has had painful periods may find ovarian stimulation familiar. Someone who has never had a pelvic examination may find the scans more difficult. A previous pelvic infection, endometriosis, cervical narrowing or anxiety about examinations can also change the experience.
My practical answer to “Is IVF painful?” is this: the physical discomfort is usually manageable, but it should never be dismissed. A patient deserves preparation, pain relief and the freedom to say when something hurts.
1. The first scans and blood tests
Before stimulation begins, I usually perform a baseline transvaginal ultrasound and arrange blood tests. The ultrasound probe is covered, lubricated and inserted gently into the vagina. It can feel like pressure, stretching or awkwardness. For some women it is painless. For others, especially those with vaginismus, pelvic pain, endometriosis or a history of trauma, it can be genuinely uncomfortable.
The scan itself is generally short. I ask the patient to tell me if she needs me to pause. There is no prize for tolerating pain silently. A clinic that treats a patient’s discomfort as an inconvenience is not providing good care.
The blood test produces the familiar brief prick in the arm. The more difficult part for many patients is not the needle but the number of appointments that follow. They have to arrange time away from work, travel to the clinic and manage the cycle around family obligations. This is particularly difficult for women who have not told their employers or relatives about their treatment.
I have written earlier about why ignoring patient questions in IVF is dangerous. Pain is one of those questions. If we do not answer it properly, patients fill the gap with the worst stories they can find.
2. What do IVF injections feel like?
Ovarian stimulation involves daily hormone injections. These medicines encourage the ovaries to develop several follicles rather than the single dominant follicle that usually develops in a natural menstrual cycle.
Most stimulation injections are given under the skin, often in the lower abdomen or thigh. The needles are small. The injection usually feels like a brief sting or pinch, followed by mild soreness. Some women notice a small bruise. Some feel nothing after the first few injections. A few find the injections painful, particularly if they are anxious, use a poor technique or inject repeatedly into the same area.
The first injection is often the hardest psychologically. I have seen patients spend ten minutes preparing themselves, only to say afterwards, “That was all?” Their fear was larger than the needle.
That does not mean I advise patients to be casual about it. I ask them to learn the technique properly, rotate injection sites, use the medicine at the prescribed time and contact the clinic if they are unsure about the dose. A partner can administer the injection, but the patient should still understand what is being given and why.
During stimulation, the ovaries enlarge. This can produce:
- lower abdominal heaviness;
- bloating and a feeling of fullness;
- mild pelvic discomfort;
- breast tenderness;
- fatigue or irritability.
This is not usually sharp pain. It is more often the sensation of being uncomfortable in one’s own body. Tight clothing may become unpleasant. Walking quickly or exercising vigorously may not feel sensible. I advise patients to avoid strenuous activity when the ovaries are enlarged, because enlarged ovaries are more vulnerable to twisting.
Severe or increasing abdominal pain, marked abdominal distension, vomiting, breathlessness, faintness or reduced urine output should not be treated as “normal IVF discomfort”. These symptoms require prompt medical advice. Ovarian hyperstimulation syndrome is less common with current treatment approaches than it used to be, but it remains a real complication. Pain that is severe, sudden or associated with vomiting also needs assessment because ovarian torsion, although uncommon, is an emergency.
3. Are the monitoring scans painful?
During stimulation, I monitor follicle growth with repeat transvaginal ultrasounds, along with blood tests when required. The scans are usually not painful, but they can be uncomfortable because the ovaries become larger and more sensitive.
There is also an emotional component. Patients sometimes assume that more follicles automatically mean a better outcome. They watch the monitor and count circles. I understand why. But a follicle is not the same as a mature egg, a mature egg is not the same as a fertilised egg, and a fertilised egg is not the same as an embryo capable of implanting and developing into a pregnancy.
This is one reason I try to explain the plan before the cycle starts. Otherwise every scan becomes a high-stakes examination in the patient’s mind. A small follicle may cause panic. A slower response may feel like failure. A large number may create unrealistic confidence.
The scan is a clinical measurement, not a verdict.
4. Does the trigger injection hurt?
When the follicles are ready, we prescribe a trigger injection to complete the final maturation process and time the egg retrieval. The injection itself usually feels much like the earlier stimulation injections: a short sting, perhaps some local soreness.
The timing matters greatly. The egg retrieval is scheduled a precise number of hours after the trigger. If the injection is taken late, mixed incorrectly or missed, the cycle may be affected. I therefore tell patients to treat this injection as a timed medical instruction, not as just another dose.
Most patients are more nervous about getting the timing right than about the pain of the injection. That is sensible. The discomfort lasts seconds; the timing can influence the entire cycle.
5. Is egg retrieval painful?
This is the stage patients fear most. Eggs are collected by passing a needle through the vaginal wall into the ovaries, guided by transvaginal ultrasound. Hearing this description can sound alarming. I would be alarmed too if I imagined the procedure being done while fully awake without pain relief.
In a properly equipped fertility unit, egg retrieval is performed with sedation or anaesthesia appropriate to the patient and the clinic’s protocol. The aim is that the patient does not experience the procedure as painful. She may be asleep or in a deeply relaxed state while the doctor collects the eggs from the follicles.
Afterwards, cramping is common. It may resemble period pain. There can be pelvic soreness, light vaginal bleeding, fatigue or grogginess from the anaesthetic. Many women rest for the remainder of the day and return to normal activities relatively quickly, although the exact recovery depends on the number of follicles, the difficulty of the procedure, the patient’s health and the type of anaesthesia used.
I do not tell patients that egg retrieval is “nothing”. It is an invasive procedure. It carries risks including bleeding, infection and injury to nearby structures, although serious complications are uncommon. The important point is that the procedure should be explained, consented for and performed with appropriate monitoring and pain control.
Patients should ask:
- What type of sedation or anaesthesia will be used?
- Who will administer and monitor it?
- How long will I need to stay at the clinic?
- Can I drive home afterwards?
- Whom should I call if I develop pain or bleeding at home?
A responsible clinic will answer these questions without irritation. The patient is not being difficult. She is trying to understand an invasive procedure involving her body.
6. What happens after egg retrieval?
Most women experience some pelvic cramping after retrieval. A hot-water bag, rest and the pain medicine advised by the doctor may help. I am careful about prescribing medication because the treatment may continue into the implantation or early pregnancy period, and not every over-the-counter painkiller is appropriate in every situation.
Light spotting can occur. Heavy bleeding is not something to ignore. Neither are severe pain, fever, persistent vomiting, breathlessness, fainting or rapidly increasing abdominal swelling. Patients should receive written instructions before leaving the clinic, not be expected to remember everything while still drowsy.
The physical recovery is only one part of that day. The embryology laboratory may call later with the number of eggs retrieved, the number that were mature and the progress of fertilisation. Patients often attach enormous significance to the first number. But the journey from eggs to embryos involves several biological filters. A lower number of eggs does not automatically mean that the cycle has no chance, and a high number does not guarantee success.
That uncertainty is painful in a different way. I have seen patients cope well with the injections and retrieval but become distressed by every laboratory update. In my earlier reflection on a patient’s IVF journey, I wrote about how much of fertility treatment is lived between appointments—in the waiting, interpreting and hoping.
7. Is embryo transfer painful?
Embryo transfer is usually the least painful part of IVF. A thin catheter is passed through the cervix into the uterus, and the embryo is placed inside. The procedure is generally similar to a cervical examination or Pap smear.
Some women feel pressure when the speculum is inserted. Others feel a brief cramp as the catheter passes through the cervix. If the cervix is narrow or angled, the transfer may take longer and may be more uncomfortable. A full bladder is sometimes requested to improve visibility and straighten the angle of the uterus; this can add to the discomfort, but it is temporary.
The embryo cannot fall out because the patient stands up after transfer. Walking to the bathroom does not undo the procedure. I tell patients this because many feel they must lie perfectly still for hours. Ordinary gentle activity is generally acceptable unless their doctor has given different instructions.
Severe pain after transfer is not expected. Mild cramps or a small amount of spotting may occur, but significant pain or heavy bleeding should be reported.
Can IVF cause pain after the transfer?
Some discomfort after transfer may come from the procedure itself. Some may be related to progesterone, which can cause bloating, breast tenderness, constipation and pelvic heaviness. Constipation is particularly common and can be mistaken for uterine pain.
Patients also become hyperaware of every sensation. A twinge that would normally be ignored becomes a possible sign of implantation or failure. This is understandable but exhausting. Unfortunately, symptoms cannot reliably tell us whether an embryo has implanted. Some women feel nothing and become pregnant. Others feel cramps and remain pregnant. Others feel exactly the same sensations and receive a negative result.
There is no bodily sensation that can replace the pregnancy test at the appropriate time.
If the test is positive but there is pain or bleeding, the patient should contact the clinic. Early pregnancy after IVF needs appropriate follow-up. A positive test is encouraging, but it is not the end of monitoring. My post on pregnancy of unknown location after IVF explains why pain and an uncertain early scan sometimes require careful assessment rather than immediate reassurance or panic.
What makes IVF more painful for some patients?
There is no single “normal” IVF experience. Pain can be influenced by:
- endometriosis or adenomyosis;
- previous pelvic surgery or infection;
- vaginismus or difficulty tolerating examinations;
- fibroids or an anatomically difficult cervix;
- the number and size of developing follicles;
- the type of anaesthesia used for retrieval;
- anxiety, previous trauma or fear of needles;
- the skill and manner of the clinical team.
The last factor is often underestimated. A technically competent doctor can still make a patient’s experience worse by rushing, failing to explain what is happening or treating her fear as irrational. Pain is not just a signal from tissue. It is also shaped by anticipation, trust and control.
This is not an argument that pain is “all in the mind”. It is an argument for taking the mind seriously. A patient who knows what will happen, has permission to pause and trusts the team may experience the same physical procedure differently from a patient who feels trapped and uninformed.
How I suggest patients prepare for the physical discomfort
I do not recommend trying to be heroic. I recommend being organised.
- Learn the injection technique. Ask the nurse to demonstrate it. Confirm the dose, timing, storage and injection site. If you are unsure, call the clinic rather than guessing.
- Wear comfortable clothing. During stimulation and after retrieval, loose clothes may be more comfortable than tight jeans or restrictive waistbands.
- Plan the retrieval day. Arrange transport, take the day off and avoid important commitments. You may feel well afterwards, but you should not have to prove it.
- Ask about pain relief in advance. Find out what you may take after retrieval and what you should avoid.
- Know the warning signs. Get written instructions about severe pain, heavy bleeding, fever, vomiting, breathlessness and abdominal swelling.
- Tell us about previous difficult examinations. A history of pain, trauma or vaginismus changes how we should approach scans and transfer.
Patients sometimes apologise for asking these questions. They should not. Good counselling is part of treatment, not an optional courtesy. I would rather spend ten minutes answering a question before the cycle than deal with a frightened patient who has silently tolerated something that needed attention.
What about the emotional pain?
The physical pain of IVF is visible and therefore easier to discuss. The emotional pain is more private.
There is the embarrassment of discussing sex, periods, semen samples and vaginal examinations. There is the strain of coordinating appointments with work. There may be pressure from parents who ask when a baby is coming. Couples may disagree about how much money to spend or how many cycles to attempt. One partner may want to keep trying while the other is exhausted.
Then comes the waiting. Waiting for the follicles to grow. Waiting for the retrieval. Waiting for fertilisation results. Waiting to see how many embryos develop. Waiting for the pregnancy test. Each stage creates a new opportunity for hope and fear.
I often tell patients that IVF is an exercise in managing uncertainty. This is familiar territory to me as an angel investor. A founder can spend months building a product and still not know whether customers will pay for it. A patient can follow every instruction and still not become pregnant. In both situations, effort is necessary but does not guarantee the outcome.
The comparison has limits—fertility is not a startup pitch, and a patient is not a business case—but the emotional lesson is similar. People cope better when uncertainty is acknowledged honestly. False certainty may feel comforting for a week, but it makes disappointment harsher.
The most useful promise a fertility doctor can make is not “this will work”. It is “I will tell you what is happening, I will not hide the risks, and I will help you decide what to do next.”
When should a patient call the clinic?
I would rather a patient call unnecessarily than stay at home trying to diagnose herself from online forums. Contact the clinic promptly if pain is severe, worsening or one-sided; if there is heavy bleeding; if fever develops; if vomiting prevents fluids; if there is breathlessness, faintness or marked abdominal swelling; or if urination becomes difficult or unusually reduced.
After egg retrieval, mild cramps and light spotting can be expected. After embryo transfer, mild cramps may occur. But “expected” does not mean that every symptom should be ignored. The doctor who knows the number of follicles, the difficulty of the retrieval, the medicines used and the patient’s medical history is best placed to judge what is concerning.
Patients should also call if they are unsure about a medication or injection. A missed dose or timing error may sometimes be corrected, but only if the team knows about it. Hiding a mistake because one is embarrassed is far more dangerous than reporting it immediately.
So, is IVF painful?
Yes, some parts can hurt. The injections sting. The scans can be uncomfortable. The ovaries may feel heavy and bloated. Egg retrieval can cause cramps afterwards, although sedation or anaesthesia usually prevents pain during the procedure. Embryo transfer is usually brief and only mildly uncomfortable.
For most patients, IVF is not a continuous experience of severe physical pain. It is a series of manageable discomforts mixed with a large amount of uncertainty. The experience becomes harder when the clinic minimises symptoms, gives poor instructions or leaves the patient alone with her fears.
I want patients to remember one specific thing: if you are lying on the examination table with a transvaginal probe and you are hurting, you do not have to remain silent to be a “good” patient. Tell us. Ask us to slow down. Ask what we are doing. Ask what pain relief is available. Your body is not an obstacle to the treatment; it is the reason the treatment deserves care.
