Anti-aging Effect of Qigong and Sex 

Hormones in Male and Female Patients

Edited by: Joe Hing kwok Chu

Both males and females produce testosterone.  

Men produce testosterone in the testes and 

adrenal glands and women produce testosterone 

in ovaries and adrenal glands. 


The average male has 260 to 1,000 nanograms of

testosterone per 100 c.c. of blood plasma and the 

average woman has 15 to 70 nanograms of 

testosterone per 100 c.c. of blood plasma.


The sex drive of men depends on the level of

testosterone and the the number of receptors 

they have in the body. Men with low testosterone 

can still have a normal sex drive if they have larger

amount of receptors.


Usually the level of testosterone fluctuates during 

the day. In normal healthy men, the peak is around 8 a.m., and the low is around midnight. In men with   shenyangxu condition, the curve of testosterone production can look like an inverted V. 


As people age the sex hormone concentration in 

blood plasma changes. In normal men after middle 

age, the concentration of plasma female hormone,

estradiol (E2) tends to rise, while the levels of 

plasma male hormone, testosterone (T)  tend to 

remain normal or slightly decrease. As men get 

older the estradiol starts to remain at steady levels 

and testosterone starts to drop.


Dropping of testosterone in men not only causes 

loss of libido and impotence but also causes other



In 1976, Phillips found that of 15 middle aged 

male patients, 7 had a slower growth of beard, 

3 had gynecomastia , and three had decreased 

libido before myocardial infarction occurred.  

Four months before myocardiac infarction, 

plasma E2 rises significantly while levels of T 

were normal.


In 1982, researchers at the Shanghai Hypertension Clinic in China found that  E2 level and  or E2/T ratio increased respectively in patients with sick sinus syndrome (1981), as well as in those with Type II diabetes (1982), acute myocardial infarction  (1983) and hypertension (1984).  Administration of  kidney tonics and Yin-yang regulating herbal medicines or practice of certain type of qigong overcame various symptoms, and decreased, to various extent, the E2 levels and E2/T ratio.
