Recommendation
Gloves do not harm “embryo transfer,” but ginger and hibiscus tea can theoretically affect outcomes; stop herbal supplements (including ginger and hibiscus) 1–2 weeks before embryo transfer to minimize bleeding/hormonal risks and maximize live-birth chances. 1
Algorithmic Guidance (prioritizing morbidity, mortality, and quality of life)
Gloves
Ginger
- Risk: Antiplatelet effects and INR interactions (bleeding risk) reported with supplements; peri-procedural bleeding can jeopardize reproductive procedures. Highest-quality recent clinical guidance recommends stopping supplements 1–2 weeks pre-op. Apply the same precaution to embryo transfer. 1
- Action: Discontinue ginger supplements and concentrated products 1–2 weeks before transfer; small dietary amounts in food likely lower risk but best avoided near transfer. 1
Hibiscus tea
- Risk: Contains phytoestrogens; case report suggests potential hormonal effects relevant to IVF and thrombosis, creating uncertainty around implantation success. When evidence is mixed, act with caution to protect live-birth outcomes. 3
- Action: Avoid hibiscus tea and concentrates during stimulation and for at least 1–2 weeks before embryo transfer. 1, 3
Key Caveats and Pitfalls
- “Natural” ≠ safe peri-procedure: variable potency and interactions; stop all nonessential supplements/herbals 1–2 weeks before transfer. 1
- If on anticoagulants or with bleeding disorders, be stricter: avoid ginger entirely and inform the fertility team. 1
- Glove hygiene matters: change gloves per patient; do not reuse or wash gloves; perform hand hygiene before donning and after removing to prevent cross-contamination that could threaten procedural safety. 2
Evidence Notes
- Procedural glove guidance (infection control) is clear and longstanding: new gloves per patient; proper PPE reduces contamination risk; no harm to procedure success. 2
- Perioperative supplement guidance (most recent/highest-quality applicable evidence): discontinue herbals 1–2 weeks pre-surgery to reduce bleeding/sedation risks; extrapolated to embryo transfer to protect implantation and maternal safety. 1
- Hibiscus hormonal effects: limited to case-level evidence; given IVF sensitivity to hormonal milieu, avoidance is prudent. 3
