Prostatic cancer, coital rates, vasectomy and testosterone

Area of Science:

• Urology
• Oncology
• Endocrinology

Background:

• Prostate cancer aetiology is often linked to androgens.
• Existing theories do not fully explain all observed epidemiological associations.

Purpose of the Study:

• To reconcile the association of prostate cancer with varying coital rates and vasectomy with androgenic involvement.

Main Methods:

• This is a theoretical note, not an experimental study.
• It involves re-interpreting existing hypotheses and observations.

Main Results:

• The androgenic hypothesis can accommodate associations with both low and high coital rates.
• The hypothesis can also explain the apparent link between prostate cancer and vasectomy.

Conclusions:

• Androgenic involvement remains a plausible unifying factor in prostate cancer aetiology.
• Further research may explore these reconciliations in more detail.
