The Claim
Increased intramuscular androgen receptor protein content following resistance training is associated with greater muscle hypertrophy, suggesting that enhanced sensitivity to testosterone may contribute to individual differences in training responsiveness; however, some studies report conflicting results, indicating the relationship requires further validation.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who build more muscle from lifting weights might be more sensitive to testosterone because their muscles have more 'testosterone receivers' after training — but scientists aren’t completely sure yet.
See the scientific wording
Higher intramuscular androgen receptor protein content following resistance training is associated with greater muscle hypertrophy, suggesting enhanced sensitivity to testosterone may contribute to being a high responder. Two studies reported that increases in androgen receptor protein correlated with fiber cross-sectional area and lean body mass gains, although one conflicting study found no difference between high and low responders, indicating the relationship requires further validation.
What the research says
1 studyThe study looks at people who gain more or less muscle from weight training and finds that those who gain more muscle tend to have more testosterone receptors in their muscles, which supports the idea that these receptors help some people respond better.
