Just to clarify a point in my post above, about the testing of the predicted gender difference in lymphatic drainage efficiency. Obviously because of my personal position, i cannot possibly organise or conduct such testing myself. I think most would agree that such a proven gender difference, and the identification of the cause of this would be important. I am therefore hoping to involve professional scientists in achieving this testing. I am open to any suggestions about the technicalities of testing this, and i would like to propose the following test based upon the previous gender related study of lymphatic function below. "Quantification of the initial lymphatic network in normal human forearm skin using fluorescence microlymphography and stereological methods". Link to abstract: http://www.ncbi.nlm.nih.gov/pubmed/9327386 This is a particularly relevant study to this question, as it unexpectedly discovered significant gender differences in three of the four lymphatic parameters measured. Women demonstrating lower values than men. The androgen implicated here is Dihydrotestosterone (DHT). A medical cream containing DHT is available as Androstanolone, brand name Andractim. I think the prior use of Andractim by some women in the testing area, would be a fair test in a repeat of the study above. If it is DHT that is causing these noted differences in gender lymphatic function, women treated should demonstrate a significant shift towards the male measured values. These are my thoughts on such testing, and i would welcome any constructive input. Regards. Stephen Foote.
