Female infertility can happen when ovulation, egg quantity or quality, fallopian tubes, the uterus, hormones, endometriosis, age, or other health factors interfere with conception or pregnancy.
The most common female-related infertility causes include ovulation disorders, age-related fertility decline, fallopian tube problems, uterine factors, endometriosis, and hormonal or endocrine conditions.
Infertility is not always caused by the female partner. A complete fertility evaluation should include semen analysis when sperm is part of the equation. ASRM recommends evaluating ovulation, reproductive tract structure and patency, and semen when appropriate.
Female fertility declines with age, and ASRM identifies female age as the single most important predictor of fecundity.
Health Youniversity’s whole-body fertility approach supports reproductive health through Nutrition, Circulation, Lifestyle, and Emotional Support.
Infertility in women can be caused by ovulation problems, age-related egg changes, diminished ovarian reserve, blocked fallopian tubes, uterine conditions, endometriosis, endocrine disorders, pelvic adhesions, lifestyle and environmental factors, or unexplained factors. The first step is not to guess the cause, but to get a timely fertility evaluation that looks at ovulation, ovarian reserve, the uterus, fallopian tubes, medical history, and sperm health when sperm is involved.
Introduction
When pregnancy does not happen as expected, many women immediately ask, “What is wrong with my body?”
That question can feel heavy. It can also lead to months of guessing, over-supplementing, cycle tracking, internet searching, and self-blame.
Here’s what matters: infertility is not a personal failure.
Female infertility can have many causes, and many of them are diagnosable, treatable, or manageable with the right support. The goal is not to assume. The goal is to understand which part of the reproductive process may need more information, more support, or a different strategy.
This guide explains the most common causes of infertility in women, what symptoms may point to each cause, what tests may help, when to seek care, and how Health Youniversity’s whole-body fertility framework can support the process.
Female infertility means difficulty getting pregnant or carrying a pregnancy due to factors involving ovulation, eggs, fallopian tubes, uterus, hormones, pelvic health, age, or other female reproductive or whole-body health factors.
Infertility itself is commonly defined as not achieving pregnancy after 12 months or more of regular, unprotected intercourse. WHO defines infertility as a disease of the male or female reproductive system marked by failure to achieve pregnancy after 12 months or more of regular unprotected sexual intercourse.
For women age 35 or older, many guidelines recommend evaluation sooner. ASRM recommends infertility evaluation after 12 months of trying for women under 35, after 6 months for women 35 or older, and more immediate evaluation for women over 40 or when a known fertility-related condition is present.
Female infertility does not mean the body is broken.
It means one or more steps in the reproductive process may need evaluation.
Female infertility is often misunderstood.
It is not:
Always permanent
Always caused by the woman
Always solved by lifestyle changes
Always a sign that IVF is the only option
Always caused by one obvious diagnosis
Always visible through symptoms
Always explained by a single hormone test
A reason for shame or self-blame
Many people think infertility means “try harder” or “relax more.”
The better way to understand it is this: infertility means the reproductive process needs better information.
Understanding the cause of infertility matters because treatment depends on the reason pregnancy is not happening.
For example:
If the cause is…
The next step may involve…
Irregular ovulation
Ovulation evaluation, hormone testing, PCOS or thyroid assessment
Blocked fallopian tubes
HSG/SHG testing, surgical review, or IVF discussion
Uterine polyps or fibroids
Imaging, hysteroscopy, or surgical consultation
Endometriosis
Pelvic evaluation, pain history, imaging, laparoscopy in select cases, or fertility treatment
Age-related egg changes
Earlier fertility evaluation, ovarian reserve testing, IVF or egg freezing discussion
Male factor infertility
Semen analysis and possible urology referral
Unexplained infertility
Review of completed testing, timing, IUI, IVF, or additional evaluation
ACOG notes that the most common cause of female infertility is a problem with ovulation, while other factors include age, lifestyle, health conditions, fallopian tube scarring or blockages, and hormone or reproductive organ issues.
The goal is not to label the body.
The goal is to identify the most useful next step.
To understand what can cause infertility, it helps to understand what has to happen for pregnancy to occur.
For pregnancy to happen:
The ovary releases a mature egg.
Sperm travels through the cervix and uterus.
Sperm reaches the egg, usually in the fallopian tube.
Fertilization occurs.
The fertilized egg travels toward the uterus.
The embryo implants into the uterine lining.
Pregnancy continues developing.
Mayo Clinic explains that female infertility can happen when one or more factors disrupt this process at any step.
That is why fertility evaluation often looks at several areas at once: ovulation, ovarian reserve, fallopian tubes, uterus, sperm, hormones, and medical history.
1. Ovulation Disorders
Ovulation disorders happen when the ovaries do not release an egg regularly or at all.
This is one of the most common causes of female infertility. ASRM states that ovulatory dysfunction is identified in about 15% of all infertile couples and accounts for up to 40% of infertility in women.
Ovulation problems may show up as:
Irregular periods
Absent periods
Long cycles
Very short cycles
Unpredictable bleeding
No clear ovulation signs
Difficulty detecting an LH surge
Spotting or cycle changes
Common causes of ovulation problems include:
PCOS
Thyroid dysfunction
Hyperprolactinemia
Perimenopause
Primary ovarian insufficiency
Significant weight gain or weight loss
Excessive exercise
Hypothalamic dysfunction
Certain medications or health conditions
Mayo Clinic identifies PCOS, hypothalamic dysfunction, and primary ovarian insufficiency as ovulation-related causes of female infertility.
What to ask your provider:
“Am I ovulating regularly, and what might be disrupting ovulation?”
2. PCOS
PCOS, or polycystic ovary syndrome, can cause infertility by disrupting ovulation.
Not everyone with PCOS is infertile, and many people with PCOS do conceive. But PCOS can make ovulation less predictable, which can make timing conception more difficult.
PCOS may be associated with:
Irregular cycles
Long cycles
Acne
Excess facial or body hair
Insulin resistance
Weight changes
Multiple small follicles on ultrasound
Elevated androgens
Mayo Clinic describes PCOS as a hormone imbalance that affects ovulation and notes that it is associated with insulin resistance, obesity, abnormal hair growth, and acne.
What to ask your provider:
“Do my cycle pattern, symptoms, labs, or ultrasound suggest PCOS, and am I ovulating?”
3. Age-Related Fertility Decline
Age can affect fertility because egg quantity and egg quality generally decline over time.
This does not mean pregnancy is impossible after 35 or 40. It means time becomes more important, and earlier evaluation may be appropriate.
ASRM states that female fertility declines with increasing age and that female age is the single most important predictor of fecundity.
Age can affect:
Egg quantity
Egg quality
Embryo chromosomal health
Miscarriage risk
Ovarian response to fertility medications
Time to pregnancy
ACOG explains that fertility begins declining in the early 30s, declines more rapidly after age 37, and that by age 40, the chance of pregnancy is less than 10% per menstrual cycle.
What to ask your provider:
“Given my age, how long should I keep trying before testing or treatment?”
4. Diminished Ovarian Reserve
Diminished ovarian reserve means the number of eggs available in the ovaries may be lower than expected for age.
Ovarian reserve testing does not perfectly predict whether someone can get pregnant naturally. But it can help guide fertility planning, especially during infertility evaluation, IVF preparation, or egg freezing discussions.
Possible ovarian reserve tests include:
AMH
FSH
Estradiol
Antral follicle count by ultrasound
ASRM states that ovarian reserve testing should not be used as a general screening test for women who do not meet infertility criteria, but it can serve as an adjunct to the evaluation of infertile women.
What to ask your provider:
“What do my ovarian reserve results mean in the context of my age, cycle history, and fertility goals?”
5. Fallopian Tube Problems
Fallopian tube problems can cause infertility when sperm and egg cannot meet or when a fertilized egg cannot travel properly to the uterus.
Fallopian tubes are where fertilization often happens. If one or both tubes are blocked, scarred, or damaged, natural conception may become difficult.
Possible causes include:
Past pelvic infection
Untreated sexually transmitted infections
Pelvic inflammatory disease
Prior ectopic pregnancy
Endometriosis
Abdominal or pelvic surgery
Scar tissue or adhesions
WHO lists tubal disorders, including blocked fallopian tubes, as a cause of female reproductive infertility and notes that they can be related to untreated STIs, unsafe abortion complications, postpartum sepsis, or abdominal/pelvic surgery.
ASRM recommends HSG or SHG to evaluate tubal patency when needed.
What to ask your provider:
“Do I need an HSG or saline sonogram to check whether my fallopian tubes are open?”
6. Uterine Factors
Uterine factors can affect fertility when the uterus or uterine lining interferes with implantation or pregnancy development.
Possible uterine factors include:
Fibroids
Polyps
Uterine septum
Scar tissue
Adhesions
Chronic inflammation
Congenital uterine differences
Endometrial cavity abnormalities
WHO lists uterine disorders as possible causes of infertility, including inflammatory causes like endometriosis, congenital causes like septate uterus, and benign causes like fibroids.
Not every fibroid or uterine finding causes infertility.
Location matters. Size matters. Whether the uterine cavity is affected matters.
What to ask your provider:
“Could my uterine lining or uterine cavity be affecting implantation?”
7. Endometriosis
Endometriosis can contribute to infertility through inflammation, pelvic adhesions, ovarian involvement, and changes in reproductive anatomy.
Endometriosis happens when tissue similar to the uterine lining grows outside the uterus. It can affect the ovaries, fallopian tubes, peritoneum, bowel, bladder, and other pelvic structures.
Symptoms may include:
Painful periods
Pelvic pain
Pain with sex
Bowel or bladder symptoms around the period
Heavy bleeding
Pain that disrupts daily life
Infertility with few obvious symptoms
ACOG states that endometriosis occurs in about 1 in 10 women of reproductive age and is most often diagnosed in women in their 30s and 40s.
ASRM notes that peritoneal factors, such as endometriosis and pelvic or adnexal adhesions, may cause or contribute to infertility.
What to ask your provider:
“Could endometriosis or pelvic adhesions be part of my infertility picture?”
8. Thyroid and Endocrine Disorders
Hormonal and endocrine disorders can interfere with ovulation, cycle regularity, implantation, or pregnancy maintenance.
The reproductive system is connected to the brain, thyroid, adrenal system, metabolic health, and pituitary hormones.
Possible endocrine-related factors include:
Thyroid dysfunction
Hyperprolactinemia
PCOS
Hypothalamic amenorrhea
Insulin resistance
Primary ovarian insufficiency
Perimenopause
ACOG notes that problems with the thyroid gland or pituitary gland can affect fertility. NICHD also lists endocrine disorders, including thyroid disease and hypothalamic problems, as possible causes of failure to ovulate.
What to ask your provider:
“Should we check thyroid, prolactin, or other hormones that may affect ovulation?”
9. Pelvic Adhesions or Prior Surgery
Pelvic adhesions are bands of scar tissue that can affect the ovaries, fallopian tubes, uterus, or surrounding pelvic structures.
Adhesions may develop after:
Pelvic infection
Endometriosis
Appendicitis
Abdominal surgery
Pelvic surgery
Prior ectopic pregnancy
Ovarian cyst surgery
Adhesions can interfere with the movement of the egg, sperm, or embryo through the reproductive tract.
ASRM notes that pelvic or adnexal adhesions may cause or contribute to infertility.
What to ask your provider:
“Could my surgical history or pelvic pain suggest adhesions or tubal issues?”
10. Cervical or Sexual Function Factors
Sometimes infertility is related to cervical, sexual, or intercourse-related factors.
These may include:
Pain with intercourse
Vaginismus
Sexual dysfunction
Low intercourse frequency
Difficulty timing intercourse
Cervical procedures or scarring
Lubricants that may impair sperm movement
Medical conditions affecting sexual health
ASRM includes sexual dysfunction among conditions that may warrant earlier infertility evaluation.
This category can be sensitive, but it matters.
Fertility evaluation should include practical questions about timing, pain, intercourse frequency, and barriers to sperm reaching the cervix.
What to ask your provider:
“Could pain, timing, lubricant use, or sexual function be affecting our ability to conceive?”
11. Lifestyle and Environmental Factors
Lifestyle factors do not explain every infertility case, but they can affect ovulation, hormone balance, inflammation, sperm health, and pregnancy readiness.
Possible factors include:
Smoking
Heavy alcohol use
Recreational drug use
Very high or very low body weight
Excessive exercise
Poor sleep
High stress without support
Environmental toxins
Certain workplace exposures
Unreviewed medications or supplements
ACOG notes that lifestyle factors, including weight, exercise, smoking, and alcohol, can affect fertility.
The goal is not to blame lifestyle.
The goal is to identify modifiable barriers while also getting appropriate medical evaluation.
What to ask your provider:
“What lifestyle factors are most relevant to my fertility picture, and which changes are actually worth prioritizing?”
12. Unexplained Infertility
Unexplained infertility means standard testing has not found a clear reason pregnancy has not happened.
This can feel frustrating because “unexplained” can sound like “nothing is wrong.”
But unexplained does not always mean nothing is happening.
It may mean the issue is not visible through the first round of testing, or that subtle factors involving egg quality, sperm function, fertilization, embryo development, tubal function, endometriosis, inflammation, or implantation are harder to measure.
ACOG notes that sometimes no cause of infertility is found, which is called unexplained infertility.
What to ask your provider:
“What has been ruled out, what has not been tested, and what are the next reasonable options?”
Category

Some people with infertility have no obvious symptoms. But certain patterns can suggest that evaluation should happen sooner.
Symptom or History
Possible Concern
Cycles shorter than 21 days or longer than 35 days
Ovulation or hormone issue
Absent periods
Anovulation, hypothalamic amenorrhea, POI, endocrine issue
Very painful periods
Endometriosis, fibroids, pelvic pathology
Pain with sex
Endometriosis, pelvic floor dysfunction, infection, other pelvic conditions
Heavy bleeding
Fibroids, polyps, hormonal imbalance
Spotting between periods
Hormonal or uterine factors
Prior pelvic infection
Tubal damage or adhesions
Prior ectopic pregnancy
Tubal factor risk
Recurrent miscarriage
Pregnancy loss evaluation may be needed
Age 35 or older
Earlier evaluation recommended
Known PCOS or endometriosis
Earlier evaluation may be appropriate
Mayo Clinic notes that cycles that are too long, too short, irregular, or absent can mean a person is not ovulating.
The timing depends on age, cycle pattern, medical history, and symptoms.
Situation
When to Seek Care
Under 35, regular cycles, no known risk factors
After 12 months of trying
Age 35 or older
After 6 months of trying
Over 40
Consider evaluation now
Irregular or absent periods
Seek care sooner
Known or suspected PCOS
Seek care sooner
Known or suspected endometriosis
Seek care sooner
Recurrent miscarriage
Seek care sooner
Prior ectopic pregnancy
Seek care sooner
Prior pelvic infection or tubal disease
Seek care sooner
Known sperm concerns
Seek care sooner
Prior chemotherapy, radiation, or ovarian surgery
Seek care sooner
ASRM recommends earlier evaluation when there is a known medical history associated with infertility, including irregular cycles, suspected uterine/tubal/peritoneal disease or endometriosis, known or suspected male subfertility, sexual dysfunction, or conditions that predispose to diminished ovarian reserve.
Testing should be personalized. Not everyone needs every test.
Test or Evaluation
What It Helps Assess
Menstrual history
Whether ovulation may be happening regularly
Ovulation predictor kits
LH surge before ovulation
Progesterone blood test
Whether ovulation likely occurred
AMH
Ovarian reserve context
FSH and estradiol
Ovarian reserve and cycle context
Antral follicle count
Ovarian reserve by ultrasound
TSH
Thyroid function
Prolactin
Hormone issue that can disrupt ovulation
Transvaginal ultrasound
Ovaries, uterus, fibroids, cysts, follicle count
HSG or SHG
Fallopian tube patency and uterine cavity
Hysteroscopy
Inside of the uterus, if indicated
Laparoscopy
Endometriosis or pelvic pathology, if indicated
Semen analysis
Sperm count, movement, shape, and volume
ACOG notes that infertility testing may include blood or urine tests, ultrasound, sonohysterography, hysterosalpingography, hysteroscopy, laparoscopy, and semen analysis depending on the situation.
Health Youniversity’s Infertility guide also emphasizes that evaluation may include ovulation assessment, ovarian reserve testing, ultrasound, uterine cavity evaluation, tubal evaluation, semen analysis, thyroid testing, and other labs based on history.
Even if this article focuses on female infertility, sperm health should not be ignored.
Type
What It Means
Why It Matters
Female factor infertility
Ovulation, tubes, uterus, age, ovarian reserve, hormones, or pelvic factors are involved
Guides female-focused testing and treatment
Male factor infertility
Sperm count, motility, morphology, ejaculation, or anatomy is involved
Requires semen analysis and sometimes urology support
Combined factor infertility
Both partners have contributing factors
Treatment should address both sides
Unexplained infertility
Standard testing does not identify a clear cause
A structured plan is still possible
The existing Health Youniversity Infertility pillar page correctly frames infertility as involving female factors, male factors, both partners, or unexplained causes.
Sometimes lifestyle changes can support fertility, but they cannot fix every cause of infertility.
Lifestyle support may help with:
Blood sugar balance
Inflammation balance
Ovulation patterns
Hormone metabolism
Sleep quality
Stress resilience
Sperm health
Pregnancy readiness
But lifestyle changes cannot open blocked fallopian tubes, reverse every age-related egg change, remove every uterine factor, or cure every case of endometriosis.
Health Youniversity’s Preconception Plan emphasizes that fertility support is not only about diagnosis, labs, stress levels, weight, or food. It includes nutrition, hydration, supplementation, movement and circulation to reproductive organs, low toxic burden, and emotional mindset.
The goal is not to replace medical care.
The goal is to support the body while getting the right care.
Health Youniversity’s Preconception Plan is built around the Four Pillars of Fertility: Nutrition, Circulation, Lifestyle, and Emotional Support.
Nutrition supports hormone balance, blood sugar, inflammation, egg health, sperm health, and early pregnancy development.
This does not mean following a perfect fertility diet.
It means building steady nourishment with protein, healthy fats, fiber-rich carbohydrates, colorful plants, hydration, and provider-approved supplementation.
Circulation focuses on blood flow to the ovaries, uterus, follicles, and reproductive tissues.
This may include walking, gentle movement, qigong, stretching, acupoint stimulation, or acupuncture-informed practices when appropriate.
Lifestyle includes sleep, toxin reduction, alcohol and tobacco avoidance, movement, medication review, and daily routines that support whole-body health.
This is not about fear or perfection.
It is about lowering high-impact barriers.
Infertility can affect identity, relationships, finances, body trust, and hope.
Emotional support may include therapy, fertility coaching, guided imagery, meditation, breathwork, support groups, or mind-body practices.
Support should not be treated as optional.
Step 1: Confirm Your Timeline
Write down how long you have been trying, your age, your average cycle length, and whether your cycles are regular.
This helps determine whether you should keep trying, begin testing, or seek specialist care now.
Practical tip: Note the month you started trying and the first day of your last three periods.
Step 2: Track Cycle Patterns
Track your cycle for one to three months if you are not already doing so.
Track:
Period start date
Cycle length
Flow changes
Pain
Spotting
Cervical mucus
Ovulation test results
PMS symptoms
Intercourse timing
This helps your provider understand whether ovulation may be regular.
Practical tip: Bring this information to your appointment instead of relying only on memory.
Step 3: Schedule a Preconception or Fertility Visit
If you meet the timeline for evaluation or have risk factors, schedule with an OB-GYN, reproductive endocrinologist, or fertility specialist.
ACOG recommends evaluation after 1 year of trying, after 6 months if over 35, and sooner if over 40.
Practical tip: Ask whether you should start with basic testing or go directly to a reproductive endocrinologist.
Step 4: Ask Which Cause Each Test Is Looking For
Testing should not feel random.
Ask:
Are we checking ovulation?
Are we checking ovarian reserve?
Are we checking the uterus?
Are we checking fallopian tubes?
Are we checking thyroid or prolactin?
Are we checking sperm?
What will this result change about the plan?
That question turns testing into strategy.
Step 5: Include Sperm Testing Early
Even when female factors are suspected, sperm should still be evaluated if sperm is part of the plan.
ASRM recommends semen evaluation of the male partner when applicable and parallel fertility evaluation when relevant.
Practical tip: Ask for semen analysis early instead of waiting until every female-focused test is complete.
Step 6: Build a Whole-Body Support Plan
While testing is happening, support the body with foundational steps:
Start provider-approved folic acid or prenatal support.
Eat consistent meals with protein and fiber.
Support sleep rhythm.
Reduce smoking, vaping, heavy alcohol, and recreational drugs.
Move gently and consistently.
Review supplements with your provider.
Build emotional support.
CDC recommends 400 micrograms of folic acid daily for all women capable of becoming pregnant to help prevent neural tube defects.
Irregular cycles may be common, but they can still signal ovulation problems.
Better approach: Ask whether your cycle pattern suggests ovulation is happening regularly.
Infertility can involve female factors, male factors, both, or no clear cause.
Better approach: Include semen analysis early when sperm is part of the equation.
Time matters more after 35 because fertility declines with age.
Better approach: Seek evaluation after 6 months of trying if age 35 or older, and sooner if over 40 or if risk factors are present.
AMH can give ovarian reserve context, but it does not diagnose every fertility issue or predict natural pregnancy with certainty.
Better approach: Interpret AMH alongside age, cycle history, ultrasound findings, and the full fertility picture.
Severe period pain is not something to simply push through.
Better approach: Ask whether endometriosis, fibroids, or other pelvic factors should be evaluated.
More supplements do not always mean better fertility.
Better approach: Review all supplements, herbs, and medications with your provider.
Infertility is a medical and emotional experience, not a character flaw.
Better approach: Get information, build support, and stop carrying the process alone.

Ovulation problems are one of the most common causes of female infertility. ASRM states that ovulatory dysfunction accounts for up to 40% of infertility in women.
Yes. Regular periods often suggest ovulation, but they do not rule out fallopian tube problems, uterine factors, endometriosis, sperm issues, age-related egg changes, or unexplained infertility.
Yes. PCOS can disrupt ovulation, which can make it harder to conceive naturally. Many people with PCOS can still become pregnant with the right evaluation and support.
Yes. Endometriosis may contribute to infertility through inflammation, adhesions, ovarian involvement, or changes in pelvic anatomy. ASRM notes that endometriosis and pelvic adhesions may cause or contribute to infertility.
No. Many people with fibroids can get pregnant. Fibroids are more likely to affect fertility when they distort the uterine cavity or interfere with implantation, but the impact depends on size, number, and location.
Age affects fertility mainly through changes in egg quantity and egg quality. ASRM states that female fertility declines with increasing age and that female age is the single most important predictor of fecundity.
Common tests may include ovulation assessment, AMH, FSH, estradiol, thyroid testing, prolactin, ultrasound, HSG or SHG, uterine cavity evaluation, and semen analysis when sperm is involved. ACOG notes that infertility testing may include blood or urine tests, imaging, procedures, and semen analysis.
Seek evaluation after 12 months of trying if under 35, after 6 months if 35 or older, and sooner if over 40 or if you have irregular cycles, recurrent miscarriage, suspected PCOS, endometriosis, pelvic pain, prior ectopic pregnancy, or known sperm concerns.
Lifestyle changes may support fertility, but they cannot fix every cause. They may help with ovulation, inflammation, blood sugar, sleep, and pregnancy readiness, but blocked tubes, significant uterine factors, severe endometriosis, or age-related egg changes may require medical care.
Start by confirming how long you have been trying, tracking your cycle pattern, and scheduling a preconception or fertility evaluation. Ask your provider what tests are needed to evaluate ovulation, ovarian reserve, uterus, fallopian tubes, hormones, and sperm health.
Female infertility can have many causes.
It may involve ovulation, PCOS, age, ovarian reserve, fallopian tubes, the uterus, endometriosis, hormones, pelvic adhesions, lifestyle factors, or unexplained issues. But the next step is not to blame your body or guess your diagnosis.
The next step is to get clear information.
When you understand what may be interfering with conception, you can make better decisions, avoid wasted time, and build a fertility plan that supports both medical care and whole-body health.
If you are navigating infertility, preparing for IVF, considering egg freezing, or still hoping to conceive naturally, Health Youniversity’s Preconception Plan can help you support your fertility foundation with nutrition, circulation, lifestyle guidance, and emotional care.
