Immune Health
Immune Support & Fertility
The immune system plays a critical role in reproductive success. Both immune suppression and immune over-activation can influence implantation and reproductive function.
Why Immune Health Matters
The Immune-Fertility Connection
A balanced immune system is essential for conception and healthy pregnancy. Immune dysregulation — whether excessive inflammatory activity or inadequate immune tolerance — can impair egg quality, sperm function, implantation and early pregnancy maintenance. Improving immune resilience helps create a healthier internal environment for conception.
Inflammatory Load
Chronic low-grade inflammation can interfere with ovulation, implantation and sperm function. Identifying and reducing inflammatory burden is a key part of fertility optimisation.
Gut-Immune Interactions
The gut microbiome is central to immune regulation. Poor gut health can drive systemic inflammation and immune dysregulation that affects reproductive outcomes.
Uterine Microbiome
The uterine microbiome plays a direct role in the immune environment of implantation. An abnormal endometrial microbiome activates local immune responses that can prevent embryo attachment and contribute to recurrent miscarriage.
Nutritional Support for Immune Resilience
Key nutrients including zinc, selenium, vitamin D, omega-3 fatty acids and antioxidants support healthy immune function and reduce oxidative stress.
Stress Physiology
Chronic psychological and physiological stress suppresses immune regulation, disrupts cortisol rhythms and can impair the immune environment needed for successful implantation.
Mitochondrial Support
Mitochondrial function underpins both immune cell energy and reproductive cell health. Supporting mitochondrial resilience benefits both immune and fertility outcomes.
Our Approach
Personalised Immune Optimisation
Levitas fertility optimisation programmes assess immune markers, inflammatory load, gut health and nutritional status as part of a comprehensive diagnostic workup. Where immune factors are identified as contributors to fertility challenges, targeted strategies are incorporated into a personalised optimisation pathway.
For Couples
Advanced Reproductive Immunology Testing
For couples experiencing recurrent miscarriage, recurrent implantation failure or idiopathic infertility, the immune interaction between mother and father is a critical and frequently overlooked dimension of investigation.
Reproductive immunology testing assesses the mother's innate immune response — including TH1/TH2 balance, TNF-alpha, regulatory T-cells (Tregs) and NK cell activity — as well as partner HLA compatibility and alloimmune factors. Where immune incompatibility or dysregulation is identified, targeted immunological intervention can be initiated.
Maternal Immune Assessment
Assessment of the mother's innate immune environment and its impact on implantation and early pregnancy.
- TH1/TH2 cytokine balance
- TNF-alpha and pro-inflammatory cytokines
- Regulatory T-cell (Treg) function
- Uterine NK cell activity
- Antiphospholipid antibodies
- Antinuclear antibody (ANA) panel
Partner Compatibility Testing
Assessment of immunological compatibility between partners — a key factor in unexplained recurrent pregnancy loss.
- HLA matching and compatibility
- Alloimmune antibody testing
- Partner lymphocyte immunotherapy assessment
- Mixed lymphocyte reaction (MLR)
- Paternal antigen evaluation
- Immunological treatment planning
Indicated For
