Your Body Knows
Fertility is not a baseline state — it is a discretionary investment the body makes only when it senses safety, resources, and a stable internal environment. This talk explores the science of why modern life suppresses reproductive function, and what restoring the right conditions actually looks like.
Each concept below is a node in that larger picture: from the neuroendocrinology of stress and the mitochondria inside an egg, to the gut as an endocrine organ, the role of sleep, and what classical Chinese medicine understood about all of this two thousand years ago.

Why evidence rankings differ — and why that's a methodology problem, not a knowledge gap
The standard RCT framework was designed for patentable, isolatable drug interventions. It was never designed to evaluate lifestyle systems, multi-mechanism practices, or the restoration of physiological conditions the body evolved to require. When you see conflicting rankings across AI tools or research summaries, you are seeing a question mismatch — three different questions being answered as if they were one:
Q-A (Mechanism): Does this intervention address a known suppressor of reproductive function? — Evidence is often settled physiology.
Q-B (Surrogate): Does it improve fertility-specific markers (AMH, sperm parameters, menstrual regularity)? — Evidence is moderate.
Q-C (Live Birth RCT): Does it improve live birth rate in a controlled trial? — Evidence is thin for almost everything except folic acid, smoking cessation, and weight normalization.
Most AI tools give you Q-A answers dressed as Q-C answers. This presentation uses mechanistic and systems evidence as the primary standard — because that is the appropriate standard for physiological restoration, not pharmacological intervention. No one has run an RCT on whether humans need sunlight or social connection. The absence of such an RCT does not make those claims "promising." It makes them foundational. Bradford Hill argued in 1965 that biological plausibility and coherence are legitimate — and sometimes superior — grounds for causal inference.
Note also: positive studies get published, negative ones often don't. Meta-analyses of fertility supplements consistently show smaller effect sizes than the individual studies they pool.
Conditions the reproductive system evolved to require. Removing modern obstacles that suppress an intact system. Mechanistic evidence is primary — RCTs are ethically impossible or structurally redundant.
Compounds added above physiological baseline to support a specific pathway. Mechanistic evidence is primary; surrogate-endpoint studies are relevant secondary support.
Practices with well-characterised physiological mechanisms that are structurally difficult to study by RCT design — acupuncture, yoga, breathwork. Mechanistic evidence is strong; sham-control problems limit RCT conclusions.
