Endometriosis and Fertility: Symptoms, Diagnosis and IVF
Quick answer: Endometriosis can lower fertility, but it doesn't rule out pregnancy. It may cause inflammation in the pelvis, scar tissue around the tubes and ovaries, and a drop in egg reserve when cysts form on the ovaries. Depending on your age and test results, a doctor may suggest trying naturally, laparoscopic surgery, ovulation induction with IUI, or IVF.
Endometriosis is a long-term condition where tissue similar to the lining of the uterus grows outside it, usually on the ovaries, the fallopian tubes and the lining of the pelvis. It often causes painful periods and pelvic pain, and it can make getting pregnant harder. Plenty of women with endometriosis still conceive. Whether that happens naturally or with help depends on your age, your egg reserve, the state of your tubes, your partner's sperm and how widespread the disease is.
Below, we go through how endometriosis interferes with fertility, how it's diagnosed, what treatment involves, and where IVF fits in.
What is endometriosis?
The inside of the uterus is lined by the endometrium, the tissue that thickens each month and sheds as your period. In endometriosis, tissue much like it turns up in places it doesn't belong. It still reacts to your monthly hormones. It swells, bleeds a little and irritates whatever it's sitting on, and over months and years that irritation can leave scar tissue. Sometimes the scarring forms adhesions, sticky bands that hold organs together in odd positions.
According to the World Health Organization, roughly 1 in 10 women and girls of reproductive age have endometriosis. Diagnosis often takes years. In many Indian homes, severe period pain is something you're told to put up with, so women frequently reach a doctor only when they can't get pregnant.
Where does it grow?
Most often on the ovaries, the tubes, the outer wall of the uterus and the peritoneum (the thin lining of the pelvis). It also likes the pocket of space behind the uterus, just in front of the rectum.
In some women it goes deeper and involves the bowel, bladder or the tubes that carry urine from the kidneys. That's called deep endometriosis, and surgery for it is usually done by a specialised team.
What is a chocolate cyst?
The medical name is endometrioma. It's a cyst on the ovary filled with old, thick, brown blood, which is where the nickname comes from. For fertility, these cysts matter more than most other forms of the disease because they sit right inside the tissue that holds your eggs.
How is adenomyosis different?
Adenomyosis is a cousin of endometriosis. Here the lining-like tissue grows into the muscle wall of the uterus instead of outside it. Periods tend to be heavy and painful, and the uterus can feel enlarged. The two conditions often show up together, so a good scan will look for both.
Can endometriosis cause infertility?
It can, and it's one of the conditions doctors find most often in women who are struggling to conceive. Still, a diagnosis of endometriosis is not a diagnosis of infertility. Many women get pregnant without ever knowing they had it.
When it does get in the way, there are a few likely reasons. The pelvis becomes inflamed, and that environment isn't kind to eggs, sperm or a newly fertilised embryo. Scar tissue can bend or trap the tubes so they can't pick up the egg after it's released. In more advanced disease the tubes may be blocked outright. Cysts on the ovaries, and sometimes the surgery used to remove them, can reduce the number of eggs left. Researchers are also looking at whether endometriosis changes how well the uterine lining accepts an embryo, though that question isn't settled yet.
Does endometriosis lower AMH?
It can. Ovarian reserve is the doctor's term for how many eggs you have left, and it's usually estimated two ways. One is a blood test for AMH (anti-Müllerian hormone). The other is an ultrasound count of the small resting follicles in each ovary, known as the antral follicle count, or AFC.
An endometrioma can damage the healthy ovarian tissue around it. Cutting the cyst out can take some of that healthy tissue too, and AMH often falls after surgery. That's why ovarian surgery in a woman who wants children needs careful thought, preferably with a fertility specialist involved before the operation, not after.
Keep in mind that AMH measures how many eggs, not how good they are. A low number doesn't mean you can't get pregnant. It may mean your doctor won't want to wait as long before suggesting treatment.
Does the stage matter?
Doctors usually grade endometriosis from stage I to IV, minimal to severe, based on what they see during laparoscopy. Higher stages are more likely to involve cysts, adhesions and damaged tubes, so they're more often tied to fertility trouble.
The stage has surprising blind spots, though. Pain doesn't track it well. Someone with stage I disease can be in agony while someone with stage IV barely notices. And stage alone won't tell you your odds of pregnancy. After surgery, some specialists use the Endometriosis Fertility Index, which factors in your age, how long you've been trying, how well your tubes work and what the surgeon found, to estimate the chance of conceiving naturally.
What are the symptoms?
Period pain is the classic one, particularly pain that has crept up over the years or makes you miss work or college. Other common signs:
- Pelvic pain on days when you're not bleeding
- Deep pain during or after sex
- Pain when you pass stool or urine, often worse during your period
- Bloating, constipation or loose stools around your period
- Heavy or irregular bleeding in some women
- Tiredness that doesn't lift
- Trouble getting pregnant
If you've been told that pain is just part of being a woman, or that it'll settle after marriage, it's worth knowing that pain bad enough to disrupt your life isn't something you have to quietly accept. It should be checked.
Can it be silent?
Yes. Some women have no pain at all. Their endometriosis is found during fertility tests, a scan done for another reason, or an unrelated operation.
What causes endometriosis?
Nobody knows for sure. One long-standing theory is retrograde menstruation, where some period blood flows backwards through the tubes into the pelvis. Most women have a little of this, so the immune system probably plays a part too, perhaps failing to clear the stray tissue. Oestrogen feeds the condition, which is why symptoms rise and fall with the cycle. It also runs in families. If your mother or sister has it, your own risk is higher.
Starting periods early, having short cycles and having heavy flow may all add to the risk.
What doesn't cause it is anything you did. Stress didn't cause it. Neither did marrying late, focusing on your career or having used contraception.
How is endometriosis diagnosed?
It starts with a conversation. Your doctor will want to know about your periods, your pain, how long you've been trying and what you've already been told. A pelvic examination comes next, then imaging.
| Test | What it can show | What it can miss |
|---|---|---|
| History and pelvic exam | Pain patterns, tender spots, nodules, a uterus that feels fixed in place | Early or mild disease |
| Transvaginal ultrasound | Chocolate cysts, adenomyosis, and some deep disease if the sonologist is experienced | Small patches on the pelvic lining |
| MRI (selected cases) | Deep disease near the bowel, bladder or nerves, often to help plan surgery | Small surface patches |
| Laparoscopy | A direct look inside the pelvis, with biopsy and treatment in the same sitting | Very little, but it means an operation |
Is laparoscopy always needed?
Not anymore. Laparoscopy is keyhole surgery. A thin camera goes in through a small cut at the navel so the surgeon can see the pelvic organs directly. For a long time it was the only accepted way to confirm endometriosis.
The current ESHRE guideline takes a different view. It accepts ultrasound or MRI as enough for diagnosis in many women, and suggests saving laparoscopy for cases where the scans look normal but symptoms persist, where medical treatment hasn't worked, or where surgery is already planned. A clear scan isn't a complete all-clear, since tiny surface patches rarely show up on imaging.
If you're trying to conceive, the laparoscopy question becomes part of the fertility plan. Surgery costs you recovery time and may cost you some egg reserve, and those trade-offs have to be weighed against what it might gain.
Which fertility tests will you need?
The endometriosis is only one piece. Before deciding anything, your doctor will usually check:
- AMH, a simple blood test
- Antral follicle count, on an ultrasound early in your cycle
- Hormones such as FSH, LH, oestradiol, TSH for thyroid, and prolactin if needed
- Whether and when you ovulate, sometimes with a follicular study (a few scans over several days to watch an egg grow and release)
- Whether your tubes are open, using an HSG dye test or HyCoSy, an ultrasound version, unless a laparoscopy has already shown this
- A semen analysis for your husband, read against WHO reference values
That last one gets skipped more often than it should. Men in India can be reluctant to give a sample, and there's still a quiet assumption in many families that fertility is the woman's problem. It isn't. A sperm issue changes the whole treatment plan, and finding it early can spare you procedures that were never going to work.
How is endometriosis treated when you want a baby?
There are two goals here and they don't always point the same way. One is controlling pain. The other is getting pregnant. Which matters more to you right now, along with your age and test results, shapes the plan.
| Treatment | Main aim | Usually considered for |
|---|---|---|
| Pain relief medicines | Easing pain | Most women, alongside other care |
| Hormonal treatment | Easing pain, slowing the disease | Women not trying to conceive yet |
| Laparoscopic surgery | Pain relief, confirming diagnosis, sometimes better natural fertility | Selected women after a careful discussion |
| Ovulation induction with IUI | A better chance of pregnancy each cycle | Mild disease, open tubes, normal sperm |
| IVF or ICSI | Getting around damaged tubes and pelvic disease | More advanced disease, tubal damage, low reserve, age over 35, male factor, or earlier treatment that didn't work |
Will hormonal treatment help me get pregnant?
No, though it's very useful for other reasons. The pill, progestins and GnRH-based medicines settle pain by switching the cycle down, and that also switches off ovulation. While you're on most of them, you can't conceive.
ESHRE specifically advises against using these medicines to boost natural fertility. They don't improve your chances afterwards, and they eat into time you could have spent trying. Where they shine is in keeping symptoms manageable until you're ready. Don't start or stop any of them without talking to your doctor first.
Can surgery improve my chances?
For minimal to mild disease, removing or burning away the visible patches during laparoscopy may give natural conception a modest lift in some women. The surgeon can also free up adhesions and put the anatomy around the tubes and ovaries back into a more normal shape.
With moderate or severe disease the picture is murkier. Surgery may help with pain, and sometimes with fertility, but the pregnancy benefit is less certain and the operation is bigger. Each repeat surgery on the ovaries tends to cost more egg reserve, so second and third operations in women hoping to conceive are generally approached with real caution.
If surgery is on the table, get your AMH and other baseline tests done first. Then you and your doctor know exactly what you're starting with.
Does a chocolate cyst have to come out before I try?
Often it doesn't. This is one of the most common questions women bring to the clinic.
Taking the cyst out may ease pain and confirms what it is. It can also take a bite out of your egg reserve, more so if there are cysts on both sides or you've had ovarian surgery before. For women heading towards IVF, guidelines don't routinely recommend removing an endometrioma just to improve IVF results.
There are situations where surgery is still sensible. A cyst that's large or growing, pain that nothing else controls, a scan that leaves any doubt about what the cyst actually is, or a cyst positioned so that it blocks the needle path during egg collection. In some of these cases, freezing eggs or embryos before the operation is worth discussing.
Where does IUI fit in?
IUI, or intrauterine insemination, means placing washed and concentrated sperm directly into the uterus around the time you ovulate. It's usually paired with ovulation induction, where tablets or injections help one or a few eggs mature in that cycle.
For minimal or mild endometriosis, IUI can be a reasonable step if at least one tube is healthy and open and the semen analysis is normal or close to it. It's much less likely to help when the tubes are damaged, the egg reserve is low or the disease is more advanced.
Couples living around Gunjur, Varthur, Whitefield and Sarjapur Road can start their evaluation, follicle monitoring, ovulation induction and IUI with Dr. Swati Shree at EVE Women and Fertility Clinic, without travelling across Bangalore for the early stages of care.
When does IVF come in?
In IVF, eggs are collected from the ovaries and fertilised with sperm in a laboratory. A resulting embryo is then placed in the uterus. Because fertilisation happens outside the body, IVF sidesteps most of the damage endometriosis does in the pelvis and tubes.
Doctors usually start talking about IVF when one or more of these apply. The tubes are blocked or badly damaged. The disease is moderate to severe. AMH or the follicle count is low. You're over 35 and time has become a factor. There's a sperm problem as well. Surgery or IUI hasn't led to a pregnancy. Or there are cysts on both ovaries and another operation would put your reserve at risk.
ICSI (intracytoplasmic sperm injection) is a type of IVF where one sperm is injected straight into each egg. It's mainly used for significant sperm problems or when eggs didn't fertilise well in an earlier cycle.
EVE is an ART Level 1 clinic, so the IVF laboratory steps aren't done on site. Dr. Swati Shree assesses you at EVE and then guides your IVF through her partner centres in Bangalore, Apollo Fertility and Motherhood Fertility, where she consults. Egg collection, lab work and embryo transfer happen there.
What does an IVF cycle look like with endometriosis?
Mostly the same as anyone else's, with a bit of extra attention in places.
- Planning. Your doctor goes over your scans, AMH, past surgery and the semen report, then decides on a stimulation plan.
- Stimulation. Daily hormone injections, usually for about ten to fourteen days, encourage several follicles to grow. Endometriomas can affect how the ovaries respond, which is why monitoring matters.
- Monitoring. Scans and blood tests every few days, with doses adjusted as needed.
- Trigger. One final injection to bring the eggs to maturity.
- Egg collection. Done under anaesthesia with a fine needle passed through the vaginal wall, guided by ultrasound. If an endometrioma sits in the way, the team plans around it.
- Fertilisation and culture. Eggs and sperm are brought together, either by conventional IVF or ICSI, and the embryos grow in the lab for a few days.
- Transfer. A single embryo goes into the uterus, either in the same cycle or later as a frozen embryo transfer.
- Pregnancy test. A blood hCG test, usually about two weeks after egg collection, on the date your doctor gives you.
Some specialists lean towards frozen transfers for certain women with endometriosis or adenomyosis, occasionally after a stretch of hormonal preparation. This is decided individually, and the research is still catching up.
Does endometriosis make IVF less likely to work?
The biggest influence on IVF in women with endometriosis is the same as for everyone else, and that's age. After that come egg reserve and how well the ovaries respond, egg and embryo quality, sperm quality, the condition of the uterus (adenomyosis and fibroids count here) and what's happened in earlier treatment.
Some studies find that women with severe endometriosis tend to get fewer eggs at collection, while the chance of pregnancy per embryo is often fairly similar. What that means for you depends on your own numbers, and your doctor can walk you through them. Any clinic promising a baby from a single cycle isn't being straight with you.
Can you get pregnant naturally with endometriosis?
Many women do. The odds are better when the disease is mild, at least one tube is open, you ovulate regularly, your egg reserve is reasonable for your age, your husband's semen analysis is normal and you're on the younger side.
With that kind of picture, your doctor may suggest giving it a set amount of time, sometimes after laparoscopy, before moving on to treatment. If you're over 35, your AMH is low or you've already been trying for a while, open-ended waiting usually isn't the best use of the time you have.
Is egg freezing worth considering?
It can be, especially if you aren't ready for a baby yet but your reserve is under pressure. That includes women with cysts on both ovaries, women facing ovarian surgery, women whose AMH is already low for their age, and women who plan to delay pregnancy for personal or work reasons.
Frozen eggs don't come with a promise. Their chances later depend mostly on how old you were when they were frozen and how many were stored. Whether it's right for you is a personal call, and one worth making with good information rather than in a rush.
What about pregnancy with endometriosis?
Most women with endometriosis go on to have healthy pregnancies. Without periods, pain often eases for those nine months, though not for everyone.
Some research links endometriosis with a slightly higher chance of certain complications, including problems with where the placenta sits and early delivery. Your obstetrician may want to see you a little more often. That's careful monitoring, nothing more alarming than that.
Pregnancy doesn't make endometriosis go away. Symptoms often come back once periods return after delivery, so it helps to plan your ongoing care before then.
Daily life, food and feelings
No diet or supplement has been shown to cure endometriosis or reliably improve fertility with it. Online claims to the contrary are everywhere, so be wary.
That said, everyday habits do help you feel better. Ordinary home food works well, with dal, sabzi, millets or brown rice, fruit, nuts and curd. You don't need to cut out whole food groups unless your doctor has a specific reason. Walking, yoga or any gentle movement you enjoy may take the edge off pain and lift your mood. Sleep matters more than people think, and long hours and late-night screens are hard to avoid if you work in Bangalore's tech belt. Smoking and alcohol are worth dropping, for both partners.
Herbal mixes and detox kits deserve a mention too. Some can interact with treatment. Tell your doctor about anything you're taking, even if it's "only natural".
The emotional weight
Years of pain that nobody took seriously, followed by months of negative pregnancy tests, wears people down. Add relatives asking when the good news is coming and it can feel relentless.
Endometriosis is a medical condition. You didn't bring it on yourself, and fertility is something you and your partner face together. A counsellor, a support group, or just honest conversations at home can lighten the load. Looking after your mind is part of the treatment, not a distraction from it.
Myths you can let go of
"Period pain is normal, so there's nothing to check." Some cramping is normal. Pain that stops you functioning, or that's getting worse, isn't.
"Endometriosis means no baby." Plenty of women with it conceive, with or without help.
"Pregnancy cures it." Symptoms may quieten for a while, then often return after periods restart.
"Chocolate cysts always have to be removed first." Surgery isn't always needed and can lower your egg reserve.
"Hormonal tablets now will improve my chances later." They help pain, but they don't improve natural fertility, and you can't ovulate while on most of them.
"Teenagers don't get endometriosis." Symptoms often start in the teens. A schoolgirl with crippling period pain deserves a check-up.
"The right diet will make it disappear." Eating well supports your health. It won't make endometriosis vanish.
Questions worth asking your fertility doctor
- What type and stage of endometriosis do you think I have, and how certain are we?
- What do my AMH and follicle count mean at my age?
- Are my tubes open?
- Has my husband's semen been tested, and was it normal?
- Do I need surgery, and what might it do to my egg reserve?
- How long should I try naturally before we change the plan?
- Is IUI realistic for me, or should we be thinking about IVF?
- Should I freeze eggs or embryos before any operation?
- How do we manage my pain while I'm trying to conceive?
Warning signs that need urgent care
Get to an emergency department, or call your doctor straight away, if you notice any of the following.
- Sudden, severe pain in the lower abdomen, which can mean a cyst has burst or an ovary has twisted
- Fever along with pelvic pain, particularly after any procedure
- Fainting, dizziness or a racing heart
- Bad bloating, breathlessness, vomiting or hardly passing urine after fertility injections, possible signs of ovarian hyperstimulation syndrome (OHSS)
- Pain on one side, pain at the tip of the shoulder, or bleeding in early pregnancy, which can point to an ectopic pregnancy
- Heavy bleeding at any stage of pregnancy
Don't hold on until your next appointment with any of these.
When should you see a fertility specialist?
NICE and ASRM both suggest getting checked after 12 months of trying if you're under 35, or after 6 months if you're 35 or older. If you already know you have endometriosis, there's no need to wait that long.
It's also worth booking sooner if you have a chocolate cyst on one or both ovaries, if you've had ovarian surgery before, if your periods are both painful and irregular, if you've been told your AMH is low, or if treatment elsewhere hasn't worked.
For couples in East Bangalore looking for a fertility specialist who sees a lot of endometriosis, Dr. Swati Shree consults at EVE Women and Fertility Clinic in Gunjur, a short drive from Varthur, Whitefield and Sarjapur Road.
Key Takeaways
- Endometriosis is common. Around 1 in 10 women of reproductive age have it.
- It can lower fertility through inflammation, scarring, tubal damage and reduced egg reserve, yet many women still conceive.
- Ultrasound, and sometimes MRI, can often diagnose it without surgery.
- Get AMH, a follicle count, a tubal test and your husband's semen analysis done before big decisions.
- Hormonal medicines help pain but won't improve natural fertility.
- Ovarian surgery can lower egg reserve, so plan it carefully and with fertility in mind.
- IUI can suit mild disease with open tubes. IVF is more often advised for advanced disease, blocked tubes, low reserve or age over 35.
- Ask about egg freezing if surgery is coming or your reserve is already low.
- Sudden severe pain, fever, fainting or heavy symptoms after fertility injections need urgent attention.
Final Thoughts

FAQs
Can I get pregnant if I have endometriosis?
Many women with endometriosis get pregnant, some naturally and some with treatment. How likely it is for you depends on your age, how advanced the disease is, whether your tubes are open, your egg reserve and your partner's sperm. A fertility specialist looks at all of these together before suggesting whether to keep trying, try IUI or go straight to IVF.
Does endometriosis reduce AMH levels?
It can, mainly when there are chocolate cysts (endometriomas) on the ovaries. Removing those cysts surgically may lower AMH further, since some healthy ovarian tissue often comes out with them. AMH reflects how many eggs you have, not how healthy they are. A low result doesn't mean pregnancy is impossible, though it may push your doctor to start treatment sooner.
Is surgery necessary before IVF if I have endometriosis?
Usually not. Guidelines don't routinely recommend removing a chocolate cyst just to improve IVF results, because the operation can reduce egg reserve. Surgery may still make sense if pain is severe, the cyst is large or looks unusual on scans, or it sits in the way of egg collection. Your fertility doctor will help you weigh this.
Is IUI or IVF better for endometriosis?
That depends on your situation. IUI with ovulation induction may be tried for minimal or mild endometriosis, provided at least one tube is open and the semen analysis is normal. IVF is more often advised for moderate to severe disease, blocked tubes, low egg reserve, age over 35, sperm problems, or when earlier treatment hasn't resulted in pregnancy.
Can endometriosis be seen on an ultrasound?
Partly. A transvaginal ultrasound picks up chocolate cysts and adenomyosis quite well, and an experienced sonologist can spot some deep endometriosis. The small patches scattered on the pelvic lining usually don't show up. So a normal scan doesn't fully rule it out. If symptoms carry on, an MRI or a diagnostic laparoscopy may be suggested.
Will taking hormonal pills for endometriosis help me conceive later?
They won't improve your fertility. Hormonal pills and similar medicines ease pain and may slow the disease, but they stop ovulation while you're taking them, and they don't raise your chances once you stop. They're useful for keeping symptoms under control until you're ready to try. Check with your doctor before starting or stopping any of them.
Where can I get an endometriosis and fertility consultation in East Bangalore?
