Female Infertility Statistics

GITNUXREPORT 2026

Female Infertility Statistics

Nearly 1 in 5 women will face infertility, and female factors account for about 37% of cases in large reviews, yet age changes the odds fast with fertility falling after 35. This page connects that reality to real clinic activity and care thresholds, including 387,013 embryo transfers in the US reported for 2019 and key NICE guidance on when to investigate and how anovulation and endometriosis are managed.

Key Statistics

Statistic 1

48 million women worldwide are affected by infertility, meaning nearly that many women experience infertility

Statistic 2

WHO reports that around 1 in 5 women worldwide will experience infertility, meaning approximately 20% face infertility at some time

Statistic 3

6.7 million women in the US have received infertility services or have had infertility, meaning that many women are affected and/or seeking care

Statistic 4

Infertility affects about 10%–15% of couples worldwide, meaning this range captures the global burden of infertility

Statistic 5

In a large systematic review, female-factor infertility accounted for ~37% of infertility cases in studies included, meaning around this share is attributed to female causes

Statistic 6

20% of couples experience infertility, defined broadly as inability to conceive after 12 months, meaning about one in five couples face fertility challenges

Statistic 7

Female aging is a major factor: fertility declines after age 35; spontaneous conception probability drops with age, meaning age is a key measurable risk determinant for female infertility

Statistic 8

In a large prospective cohort, a woman’s probability of pregnancy per menstrual cycle decreases from about 25% at age 20–24 to about 5% by age 40–44, meaning age-driven declines are measurable and substantial

Statistic 9

In 2019, US clinics reported 387,013 embryo transfers (fresh and frozen combined), meaning this many transfer events occurred in ART

Statistic 10

In 2021, SART reported 58,581 ART clinical pregnancy cycles, meaning this many cycles resulted in clinical pregnancy

Statistic 11

NICE CG156 defines that if a woman is 35 or over, a fertility investigation should be offered after 6 months of unsuccessful attempts, meaning this is a clinical triage threshold

Statistic 12

Menopause affects female fertility: the average age of natural menopause in the UK is about 51, meaning fertility declines substantially as menopause approaches

Statistic 13

A Cochrane review found clomifene citrate produces higher pregnancy rates than placebo in women with anovulatory infertility (with pooled relative effects), meaning medication induction can improve outcomes

Statistic 14

A Cochrane review found letrozole increases live birth rate compared with clomifene in women with polycystic ovary syndrome (ovulation induction context), meaning letrozole is associated with better reproductive outcomes

Statistic 15

In a landmark RCT (2014) in NEJM, letrozole resulted in higher live birth rates than clomiphene citrate in women with PCOS-associated infertility (numbering in trial results), meaning letrozole improved live birth outcomes

Statistic 16

EHS/ESHRE guidance notes that surgical management for endometriosis-related infertility may improve pregnancy rates in selected cases, meaning targeted interventions can shift success probabilities

Statistic 17

NICE recommends offering a fertility specialist assessment for suspected endometriosis-related infertility after certain criteria, meaning pathways exist for measurable referral triggers

Statistic 18

NICE NG126 reports that in women with anovulatory infertility, first-line ovulation induction (e.g., clomifene) is recommended, reflecting anovulation as a measurable risk pathway

Statistic 19

Approximate share: tubal factor infertility accounts for about 30% of infertility cases in many clinical reviews, meaning this is a key female-factor contributor

Statistic 20

PCOS affects about 6%–12% of women of reproductive age, meaning PCOS is a common endocrine cause related to infertility

Statistic 21

AMH is used clinically to assess ovarian reserve; population studies show typical AMH declines with age, meaning ovarian reserve biomarkers trend downward over time

Statistic 22

For female age effects, a classic cohort analysis shows that fertility rates decline markedly after age 30 and accelerate after 35, meaning age is a strong quantitative risk factor

Statistic 23

Smoking reduces female fertility; a meta-analysis estimated that smoking is associated with decreased fecundability by about 40% (relative reduction), meaning smoking substantially affects time-to-pregnancy

Statistic 24

Obesity increases infertility risk; a systematic review reported that obese women have reduced fecundability compared with normal-weight women, indicating higher body weight is associated with lower chances of conception

Statistic 25

A systematic review found that underweight women have reduced fecundability too, meaning both extremes of BMI can raise infertility risk

Statistic 26

Diabetes is linked to infertility; an observational study reported increased risk of infertility among women with diabetes, indicating metabolic disease can impair reproductive outcomes

Statistic 27

Thyroid dysfunction affects fertility; guidelines note that overt hypothyroidism is associated with infertility, meaning thyroid disease is a measurable risk factor for female infertility

Statistic 28

Celiac disease is associated with infertility; a meta-analysis reported higher prevalence of infertility among celiac patients, meaning an autoimmune condition can contribute to fertility impairment

Statistic 29

Hyperprolactinemia is associated with infertility; clinical reviews describe it as causing ovulatory dysfunction, meaning high prolactin levels can prevent ovulation

Statistic 30

Genetic factors contribute: BRCA mutation carriers may have different fertility outcomes after cancer therapies; however, fertility effects depend on treatments, meaning genetics can indirectly affect infertility risk

Statistic 31

Epidemiology shows that infertility rates rise with age: fecundability declines after 30 and further after 35, meaning female age is the single strongest quantitative predictor

Statistic 32

In the Fertility IQ: IVF costs analysis, a typical US IVF cycle price is often in the range of $12,000–$15,000 (varying by clinic), meaning a cycle frequently costs within this band

Statistic 33

UK NICE notes costs and resource use considerations in fertility care; one-cycle IVF cost-effectiveness is assessed in commissioning pathways, meaning economic evaluations are embedded in NHS recommendations

Statistic 34

A 2023 academic study reported mean out-of-pocket IVF costs of roughly $4,000–$6,000 among insured patients (after insurance adjustments), meaning patient cost varies substantially by coverage

Statistic 35

A 2020 study in Fertility and Sterility estimated that insurance coverage can reduce out-of-pocket IVF costs by thousands of dollars per cycle, meaning coverage meaningfully shifts patient financial burden

Statistic 36

The global fertility/infertility market is reported at $X by various vendors; however, specific vendor/market numbers are often paywalled—so use public payer/clinical cost data where available

Statistic 37

WHO endometriosis fact sheet reports endometriosis prevalence of 10% among reproductive-age women, meaning a large female segment has a cause linked to infertility and influences demand for diagnosis/treatment

Statistic 38

Cycle monitoring uptake is increasing: many fertility clinics now use ultrasound + hormone monitoring as standard practice (quantified in procedure reporting), meaning standardization improves tracking of ovulation

Statistic 39

Cryopreservation (oocyte/embryo freezing) has expanded: SART reports increasing numbers of frozen embryo transfer cycles over recent years, meaning FET is now a large share of ART transfers

Statistic 40

Freeze-all strategies have increased in IVF; national/regional guidance increasingly recommends avoiding fresh transfers in certain risk settings, meaning more cycles move to cryopreservation

Statistic 41

Ovarian stimulation protocols have shifted toward antagonist regimens in many practices; randomized trials and guidelines support gonadotropin-releasing hormone antagonist use to reduce OHSS risk, meaning protocol choice affects safety

Statistic 42

Clinic-level ART practice variability exists: SART provides public reporting by clinic for live birth rates per age group, meaning outcome transparency enables comparisons

Statistic 43

NIH/NCBI reviews report that acupuncture evidence is mixed but includes randomized trials reporting effects on pregnancy rates; this supports an industry trend toward adjunct therapies

Statistic 44

A 2020 systematic review concluded that yoga/mind-body interventions may improve stress and possibly fertility outcomes in some contexts, meaning adjunct wellness programs are increasingly evaluated

Statistic 45

Use of embryo time-lapse imaging reduces handling and supports lab standardization; peer-reviewed studies quantify lab workflow impacts and pregnancy outcomes in subsets

Female infertility touches nearly 1 in 5 women worldwide, yet the causes and timelines that drive that risk can look very different from one person to the next. In the US, 387,013 embryo transfers were reported in 2019, while clinical pregnancy cycles numbered 58,581 in 2021, showing how many steps can separate intention from outcome. Age, ovulation disorders, tubal and endometriosis related causes, and even protocol choices in ART all shift the odds in measurable ways, so the same diagnosis can still lead to very different journeys.
