Anovulation means your ovaries are not releasing an egg during a menstrual cycle, so pregnancy cannot happen that month. Ovulation problems account for about 25% of infertility diagnoses [1]. The reassuring part is that most have a clear cause, which a few blood tests and a scan can identify, and most can be treated.
What is Anovulation?
Anovulation is easiest to understand by comparing it to a normal cycle. Each month, two brain hormones, FSH and LH, signal one follicle in the ovary to grow and release an egg. That release is ovulation. Afterwards, the empty follicle produces progesterone, which prepares the womb lining and triggers a period about two weeks later.
In anovulation, the sequence stalls before the egg is released. Doctors separate an occasional missed ovulation, which happens to almost everyone, from chronic anovulation, where it happens cycle after cycle. Oligo-ovulation lies in between: you do ovulate, but rarely and unpredictably, which makes timing hard.
Ovulatory, oligo-ovulatory and anovulatory cycles at a glance
The three patterns look different on a period calendar. A normal cycle length is 24 to 38 days .
Ovulatory
One egg released most months
Regular, 24 to 38 days
Yes
Oligo-ovulatory
An egg released only in some months
Irregular, often longer than 38 days
Only in the months you ovulate
Anovulatory
No egg released
Absent periods or irregular bleeding
No
How Common is Anovulation in India?
Anovulatory infertility is one of the most common reasons couples need help to conceive. A 2021 review in JAMA puts ovulatory disorders at about 25% of infertility diagnoses, and finds that around 70% of women with anovulation have polycystic ovary syndrome (PCOS). You may see higher figures online, such as 30% to 40%, or 80% for PCOS. These figures are often repeated without a source.
PCOS matters especially in India. A 2022 meta-analysis of Indian studies found a pooled PCOS prevalence of 11.33%, and close to 10% using the Rotterdam criteria most clinics use. Put simply, around one woman in ten of reproductive age carries a real risk of irregular ovulation from PCOS alone.
Why is infertility increasing in India?
There is no single reason. PCOS, which affects around one woman in ten, is a large part of it; specialists also see more insulin resistance, more couples trying for a first baby in their thirties, and long working hours, poor sleep, and stress that can unsettle ovulation. Awareness has grown, so more couples now ask for tests instead of waiting years.
Anovulation Symptoms: How do You Know You Are Not Ovulating?
Many women only discover anovulation after months of trying for a baby. The signs usually appear earlier, and most show up on a period calendar.
Periods far apart or missing: Cycles longer than 38 days [3], or no period at all for three months or more.
Unpredictable bleeding: A period that comes early one month and late the next, or spotting that never quite becomes a period.
Heavy or long bleeding after a gap: The womb lining keeps building without progesterone, then sheds unevenly.
No fertile mucus: No clear, stretchy, egg-white discharge you would expect mid-cycle. Our guide on fertile cervical mucus explains what to look for.
Flat ovulation tests or temperature charts: No LH surge on kits and no temperature rise in the second half of the cycle.
Signs of the cause itself: Acne, extra facial hair or weight gain with PCOS; milky nipple discharge with high prolactin; tiredness and feeling cold with an underactive thyroid.
Why am I not ovulating but having periods?
Periods are not proof of ovulation. In an anovulatory cycle, estrogen can thicken the womb lining until it breaks down and bleeds, which looks like a period even though no egg was released. These bleeds are often irregular. Some women with fairly regular cycles still skip ovulation now and then, so it is worth confirming rather than assuming. Our article on signs that you are fertile explains the physical signs that may indicate ovulation is occurring.
How doctors confirm anovulation
A fertility specialist starts with your cycle history, weight and any medicines, then orders a short set of tests. Most are blood tests timed to the cycle, plus at least one scan.
Tests used to diagnose anovulation and what each one shows
Each test answers one question, and you will not need all of them. Costs are in the section on cost below.
Mid-luteal serum progesterone
About a week before the expected period
A raised level suggests ovulation happened that cycle
FSH, LH and oestradiol
Day 2 to 5 of the cycle
Low levels point to a hypothalamic cause; a high FSH points to reduced reserve or POI
TSH and prolactin
Any day
Thyroid or prolactin problems that switch ovulation off
Testosterone and androgen profile
Any day, ideally early in the cycle
Raised androgens, most often from PCOS
AMH
Any day
Often raised in PCOS; low when egg reserve is reduced
Pelvic or transvaginal ultrasound
Early in the cycle
Polycystic ovaries, follicle count and the womb lining
Follicular monitoring scans
Several scans across one cycle
Whether a follicle grows and then releases its egg
If your cycles are irregular, you have to time the progesterone test to your cycle and sometimes repeat it, which is why a single "day 21" result can be misleading. Serial scans, explained in our guide to follicular monitoring, give the clearest picture.
When is the lowest chance of getting pregnant?
In a regular cycle, your chances are lowest during your period and in the second half of the cycle, after the egg has gone and the fertile window has closed. If you are not ovulating at all, your chance in that cycle is effectively zero, no matter what day you try. That is why treating anovulation matters more than perfect timing.
What Causes Anovulation?
Ovulation depends on a chain of signals from the brain to the ovary. A break at any point stops it. These are the causes a specialist looks for, roughly in order of how often they are found.
Polycystic ovary syndrome (PCOS): The commonest cause. Raised androgens and insulin resistance stop follicles from maturing fully. Our PCOS and pregnancy guide goes into more detail.
Thyroid disorders: Both an underactive and an overactive thyroid can disturb the cycle. Read more on thyroid problems and infertility.
High prolactin: Too much prolactin, sometimes from a small benign pituitary growth or from certain medicines, suppresses ovulation.
Hypothalamic causes: Stress, low body weight, under-eating or heavy training can raise cortisol and switch off GnRH, the brain hormone that starts the cycle. See how stress affects fertility.
Weight and insulin resistance: A high BMI and a sedentary routine can disrupt ovulation through insulin resistance, even without PCOS.
Primary ovarian insufficiency (POI): The ovaries stop working normally before 40, affecting about 1 in 100 women.
Life stages and medicines: Puberty, breastfeeding and the years before menopause, plus some hormonal and psychiatric medicines.
Anovulation Treatment: What Actually Helps
Treatment depends on the cause and on how soon you hope to conceive. The aim is one healthy egg a month, not as many eggs as possible.
How to fix anovulation naturally?
Lifestyle changes help most when weight, stress or eating patterns are part of the problem. It will not restart ovulation in POI, and it rarely works on its own for thyroid or prolactin problems.
Weight, in either direction: If your BMI is high, even modest weight loss can bring ovulation back in some women with PCOS; if it is low, regaining weight is the main treatment for hypothalamic anovulation.
Regular, balanced meals: Dal, rajma, chana, curd, paneer, eggs, and millets such as ragi and jowar keep blood sugar steadier than maida, sweets, and sugary chai.
Moderate exercise: Brisk walking, yoga, or cycling on most days. Very intense training with too little food can switch ovulation off.
Sleep and stress: Keep a regular sleep pattern; long-term stress is a recognised trigger of hypothalamic anovulation.
Supplements, with caution: Inositol is popular for PCOS, but the 2023 international guideline found limited benefit for ovulation (low certainty evidence). Check with your doctor before starting any supplement.
Medical treatment to restore ovulation
When lifestyle change is not enough, treatment usually moves up a ladder:
Treating the cause: Thyroid medicine for an underactive thyroid, or prolactin-lowering medicine for high prolactin.
Ovulation induction with tablets: Letrozole is now the first-choice medicine for anovulation caused by PCOS, with clomiphene as the older alternative. It suits women with PCOS or unexplained anovulation whose tubes are open and whose partner's semen test is normal. Our comparison of letrozole and clomid explains the difference, and Cloudnine Fertility offers ovulation induction with cycle monitoring.
Injections: Gonadotrophins are used when tablets don't work, or the cause is hypothalamic. They require close monitoring, with scans and tests for estradiol, LH, and progesterone, because more than one follicle can grow. The main risks are twins and ovarian hyperstimulation syndrome (OHSS), so doses are kept low.
Laparoscopic ovarian drilling: A keyhole procedure for PCOS that has not responded to tablets, used less often now.
IUI or IVF: When other fertility factors are present, or several ovulatory cycles have not led to pregnancy.
Most specialists review the plan after a few ovulatory cycles without pregnancy.

Costs rise with the number of monitoring scans, injection doses and cycles. A tablet-based cycle with two or three scans sits at the lower end; injection cycles and surgery under anaesthesia sit higher.
How much does a female egg release injection cost?
The trigger injection that releases a mature egg is usually a single dose given in a monitored cycle, and its price depends on the medicine and dose your doctor prescribes. Gonadotrophin injections that grow the follicles cost more because you take them daily for several days.
When Should You See a Fertility Specialist?
Do not wait a full year if your periods already suggest irregular ovulation. The usual advice to try for 12 months, or 6 months from age 35, assumes regular cycles. If yours aren't regular, the wait only delays answers a few simple tests can provide.
At the first visit, expect questions about your cycle dates, weight changes, stress, medicines and any hair or skin changes. Bring a few months of period dates if you track them, and any previous reports. Your partner's semen test is usually ordered at the same stage, so both sides are checked together.

Known PCOS, thyroid or prolactin problem and planning pregnancy
What are the chances of getting pregnant with anovulation?
For most women, the outlook is good, because the most common causes respond to treatment. The main exception is POI, where ovulation rarely returns on its own.
Age still matters, though. Treatment can restore ovulation, but it cannot make the eggs younger, so a woman of 38 with PCOS may move to IUI or IVF sooner than a woman of 28 with the same diagnosis. Your specialist will weigh both when planning how many cycles to try at each step.
Realistic outlook for pregnancy due to anovulation
These are general patterns, not a prediction for you. Your age and any other fertility factors change the picture.
PCOS
Lifestyle changes plus letrozole
About 6 in 10 treated cycles ovulate; 27.5% had a live birth within five cycles in the main trial
Thyroid or prolactin problem
Treat the hormone problem
Ovulation often returns once levels are normal
Hypothalamic (stress, low weight, over-exercise)
Restore energy balance; sometimes injections
Good once weight, food intake and training are rebalanced
Primary ovarian insufficiency
Hormone replacement; donor eggs for pregnancy
Natural pregnancy is uncommon
FAQs
Your questions, clearly answered
Find clear, trusted answers to the most common questions about IVF—designed to guide and support you every step of the way.
Can a woman with anovulation get pregnant?
Yes, many can. You cannot conceive in a cycle where no egg is released, but most causes of anovulation can be treated so that ovulation returns. Women with PCOS, thyroid problems, or high prolactin often ovulate again with treatment. The exception is primary ovarian insufficiency, where natural pregnancy is uncommon, and donor eggs are often discussed.
Can lifestyle changes restore ovulation?
Sometimes. Start by finding the cause. If weight, stress, sleep, or under-eating is involved, reaching a healthy weight, eating regular balanced meals, exercising moderately, and sleeping well can bring ovulation back for some women. Lifestyle change alone will not fix primary ovarian insufficiency and rarely corrects a thyroid or prolactin problem, so get tested first.
How long will an anovulatory cycle last?
There is no fixed length. An anovulatory cycle may end in bleeding after a few weeks, or stretch on for two or three months, because without ovulation there is no progesterone to time the next period. If your cycles keep running past 38 days, or stop for three months, see a doctor.
Can you get a period without ovulating?
Yes. Without ovulation, estrogen can still thicken the womb lining until it sheds, and that bleed looks like a period. Anovulatory bleeding is often irregular, lighter or heavier than usual, or hard to predict. A bleed that looks normal does not prove you ovulated; a mid-luteal progesterone test or follicular scans can confirm it.
Can stress cause anovulation?
Yes. Severe or long-lasting stress, especially alongside low weight, under-eating, or intense exercise, can suppress the brain hormones that trigger ovulation. Doctors call this functional hypothalamic amenorrhoea. Ovulation usually returns once stress, food intake and training are back in balance, although some women need medical treatment to restart it.
Is anovulation permanent?
Usually not. Most anovulation is temporary or treatable, whether it comes from PCOS, thyroid disease, high prolactin, stress, or a weight change. An occasional missed ovulation is normal. The main exception is primary ovarian insufficiency, where the ovaries stop working normally before 40 and ovulation returns only now and then.
Is anovulation the same as menopause?
No. Menopause is the permanent end of periods, usually in midlife, when the ovaries run out of eggs. Anovulation is a missed or stopped egg release, often in younger women, and it is usually reversible. Cycles without ovulation do become more common in the few years before menopause.
What is anovulatory bleeding?
Anovulatory bleeding is bleeding from the womb in a cycle where no egg was released. Without progesterone, the lining builds up unevenly and sheds irregularly, sometimes heavily or for longer than usual. It is a common cause of irregular periods and worth checking, because years of unopposed oestrogen can thicken the womb lining.
