Sex Ratios and Hormone Levels in Cancer
Author Information
Author(s): W.H. James
Primary Institution: University College London
Hypothesis
Can sex ratios of offspring serve as markers for hormone levels associated with certain cancers?
Conclusion
Sex ratios of offspring may reflect the hormonal profiles of parents and could be used as markers for cancers influenced by hormones.
Supporting Evidence
- Men with non-Hodgkin's lymphoma have low testosterone and high LH levels.
- The sex ratio of offspring of men with non-Hodgkin's lymphoma was significantly low.
- High sex ratios in offspring of men developing prostatic cancer suggest high androgen levels.
- High maternal estrogen levels may predispose male offspring to testicular cancer.
Takeaway
The number of boys and girls born to parents with certain cancers might tell us about the hormones involved in those cancers.
Methodology
The study suggests using sex ratios of offspring as markers for hormonal influences in various cancers.
Potential Biases
Potential biases in sex ratios due to abnormal hormone levels associated with cancers.
Limitations
Some cancers are rare, requiring large data sets to test the hypotheses effectively.
