Structural, not incidental: understanding the hormonal health equity gap

South Asian women in the UK have approximately 25% lower IVF success rates and report 23-point lower patient satisfaction scores than White patients, disparities that have persisted across HFEA reporting cycles from 2017 to 2023 (HFEA, 2024). PCOS prevalence is reported at up to 52% in South Asian cohorts compared with 20 to 25% in White UK women. These are structural gaps, not knowledge gaps, and they require structural responses.

The evidence on hormonal health inequity in the UK is not ambiguous. It is documented, quantified, and persistent across multiple reporting cycles. What is missing is not awareness of the problem. What is missing is an institutional response commensurate with its scale.

What the data shows

HFEA data consistently shows that South Asian women have approximately 25% lower IVF success rates compared to White patients. Live birth rates per embryo transferred sit at 24% for South Asian women versus 32% for White women, a 6 to 8 percentage point gap that has persisted across HFEA reporting cycles from 2017 to 2023.

The HFEA National Patient Survey 2024 found overall patient satisfaction at 73% nationally. For Asian patients, satisfaction was 50%, a 23-point deficit. Information quality satisfaction showed a 12-point gap. Only 4% of egg donors in the UK are Asian, against a 15% patient utilisation rate, a structural bottleneck in donor gamete access that forces patients into prolonged waiting lists or non-ethnically matched donors.

These are not incidental findings. They describe persistent, documented disparities in equitable access to fertility care, and the scale of the opportunity for more inclusive provision.

The compounding factors

PCOS prevalence is disproportionately elevated in South Asian populations, reported at up to 52% in some cohorts compared with 20 to 25% in White UK women (Wijeyaratne et al., BJOG). Vitamin D deficiency affects 72% of South Asian fertility patients versus 36% of White patients (Nandi et al., Fertility and Sterility). Type 2 diabetes risk for South Asian individuals rises at a BMI of approximately 23.9, equivalent to a BMI of 30 in White populations, meaning standard screening thresholds systematically miss metabolic risk in this population.

Cultural factors compound clinical factors. Strong pro-natalist norms in many South Asian communities mean infertility is often community-visible. Izzat (family honour) and sharam (shame) can drive silence around fertility difficulties. Research shows that some patients prefer non-Asian clinicians specifically due to fear of the community grapevine. Stigma is a significant predictor of psychological distress during fertility treatment.

For Pakistani and Bangladeshi communities, the barriers stack further: disproportionate representation in the lowest income quintiles, linguistic barriers in Sylheti, Urdu, and Bengali, and theological frameworks that affect treatment decisions. Sunni Islam prohibits third-party gamete donation, while Shia rulings have permitted certain forms since 1999.

Why existing provision does not address this

NHS patient information, clinical screening thresholds, and cultural competence in fertility services have not consistently reflected the diversity of the population they serve. Work is underway, but the distance between current provision and equitable access remains significant and documented.

Gynaecology waiting lists increased 60% in England between the start of the pandemic and winter 2021/22 (NHS England, 2022). Nearly 46% of gynaecology patients are beyond the NHS 18-week target (NHS England, 2024). Approximately 2% of overall public research funding is dedicated to hormonal health, unchanged for a decade (Wellcome / MRC analysis, 2023). The system is under-resourced for everyone. For those facing compounding structural barriers, the consequences are disproportionate.

What a structural response looks like

The disparity is not a knowledge gap. It is a structural gap, and structural gaps require structural responses. Awareness campaigns and translated leaflets do not address the underlying architecture of a system that screens, diagnoses, and treats based on thresholds and pathways developed for a different population.

HHEI's Community Interest Statement (the CIC36 filed with the CIC Regulator) names its beneficiary communities explicitly: people from ethnic minority and marginalised communities experiencing disproportionate health inequalities in hormonal health. This is not an add-on to HHEI's mission. It is a founding obligation, legally embedded and regulator-monitored.

Addressing hormonal health equity requires clinical depth, occupational health expertise, and cultural competence working together, held by an institution that is structurally independent and accountable to the communities it serves. That is the architecture HHEI was built to contribute.
