Why Does Aromatase Vary by Genetics? The CYP19A1 Explanation
Aromatase activity varies between men because CYP19A1 — the gene encoding aromatase — is polymorphic. Different CYP19A1 variants alter how the enzyme is expressed and how efficiently it converts testosterone to estradiol. The Precision Peptide Genetic Test analyzes CYP19A1 as part of 14 pathways and 150+ genetic insights across 49 peptides.
CYP19A1 (Aromatase) and Estrogen Conversion in Men
The Precision Peptide Genetic Test analyzes CYP19A1 — the aromatase gene that controls how much testosterone your body converts to estrogen. Part of 14 pathways and 150+ genetic insights across 49 peptides, your CYP19A1 variants help explain why estrogen levels vary between men on the same androgen-pathway protocol.
