Case Study:  Stress is the main cause of hair loss while the excessive testosterone-DHT conversion induced by sexual stimulation also elevate stress hormones production in the hypothalamus-pituitary-adrenal axis, skin and hair follicles.
Reader: 4/27/2008>Dear Dr. Lin, my new question is about reversing hair loss through stopping masturbation completely and only ejaculating during sex with wife or girlfriend. Finasteride blocks dht and has many bad side effects, but if a man has better self control and stops looking at porn and masurbating, would he be able to lower dht naturally without destroying testosterone to dht liver mechanism? Also, if a man can build up his testosterone through 7 day abstinence and then have natural intercourse with his partner he will be able to have more energy and hair growth. Does this sound accurate? Your response is very valuable to me and much appreciated. Sincerely
Dr. Lin: 4/27/2008>Actually, it is the stress causing hair loss, although sexual stimulation increases excessive testosterone-DHT conversion which in turns elevate dopamine-norepinephrine/epinephrine production for more stress responses in the hair follicles. This is called "brain-hair follicles" connection -
The DHT level reaches its peak during the male puberty, but teenager boys won't have hair loss problems and instead they grow beautiful air.  Teenagers start to experience hair loss when they indulge in sexual activities.
We find stress causing inflammatory pains, cramps, muscle stiffness, fatigue, arthritis, headaches, irregular cardiovascular output, sinus, acne, poor memory, eye floaters, blur vision, ear ringing, IBS, incontinence, PMS, menstrual pains,  impotence, premature ejaculation, and so on. All of the symptoms are similar to or identical with the sexual exhaustion symptoms as listed in
>From there, I have concluded that  when sex start to induce stress responses, your hypothalamus-pituitary-adrenal axis and liver system are evolving to let your condition that your body is easily to be stressed out.  That is, you can no longer let you stress hormones accumulate in your blood stream and cerebrospinal fluid with excessive sex, drug or works.
It is not a testosterone issue, although the hypothalamus-pituitary-adrenal  and -testicular axis are responsible for DHEA, testosterone and DHT production for sex.
When your stress hormones cortisol, norepinephrine and epinephrine level are too high, your pituitary function will dump too much prolactin, leading to the low DHEA, testosterone and DHT production - the ultimate sexual dysfunction.
That is, you can not stressed out your hypothalamus-pituitary-adrenal  and -testicular axis  if you want to have a good sexual performamce.
Older men will take about 7 days or longer to dissipate the stress hormones and to accumulate sufficient testosterone and DHT for sex, where without stress hormones acting the hair follicles, DHT won't give you hair loss.
