As an outstanding example of reproductive health, male medicine represented a human endeavour in pursuit of immortality via successful bio- physical fertility. In my presentation, I will cite the 7 key texts in traditional Chinese male medicine ( Nan ke 男科), to demonstrate how the perennial struggle with sustainability used to be carried on from the personal, family levels with broader communal and cultural implications. The comparison with Taoist texts of alchemy and immortality on the one hand, and late imperial Chinese gynaecology ( fu- ke , 婦科）on the other brings the conceptual outlook and social market of this development into shaper relief. 
It is a historical study based on textual and philological investigations, carried out with the interdisciplinary inquiries on the philosophical, even spiritual notions of unending gratification. Which stands behind the modern quest for planetary health and sustainability globally.
