Case Study:  On the effect of ejaculation on the testosterone production and aggressiveness or mode swing. Why it will take about 7 days to release the post-ejaculation or post-orgasm sexual exhaustion symptoms
Reader: 3/17/2008>A couple I am working with asked a question I could not answer. When a man ejaculates, is there an effect on testosterone serum as it relates to aggressiveness in males?  I've always thought that there is a lowering of aggression and at about 7 days post ejaculation the testosterone levels return to peak?   
Dr. Lin: 3/17/2008>Yes, but but it will take about few hours for the androgen hormonal change and for the serotonin nervous responses to ejaculation or orgasm.
Only the dopamine, GABA, norepinephrine, epinephrine and  sympathetic nervous function, cortisol, oxytocin and prolactin change respond to sex immediately.
This is because an elevating prolactin and cortisol after orgasm or ejaculation will start to lock up the testicular function if the oxytocin elevation can not overcome the lockup effects.
Ejaculation / orgasm usually burn serotonin into melatonin and  discharge GABA in semen. If your body can not converted enough 5-HTP and glutamate to serotonin and GABA respectively, you will experience post-ejaculation or post-orgasm mood swing, anxiety, short temper, aggression, stress, depression and sleeping disorders, or even worse neuro-excitotoxicity from glutamate.
In the normal cases, the cortisol level is supposed to drop and the oxytocin level to elevate to trigger an elevation of testosterone and DHT level (the testicular function) during sex, but the orgasm-induced prolactin release will counteract the the positive effects produced by decreasing cortisol and elevating oxytocin during sex.
If you have been sexually exhausted,  your hypothalamus-pituitary-adrenal and -testicular axis become too weak to produce endorphrin for modulation of the sexual arousal induced inflammatory pain, and then sexual arousal triggers excessive cortisol and prolactin release in an attempt to reduce inflammatory hormone prostaglandin E2 production and to suppress sexual function at the same time.
Therefore, excessive cortisol and prolactin induced by sexual arousal and ejaculation (orgasm) will lock up your testicular function for a low testosterone output until the inflammatory hormone prostaglanadin E2  production becomes low enough to suppress cortisol and prolactin over-shooting while the slow accumulation and elevation of DHEA, testosterone and DHT from adrenal glands and other internal organs/tissues/skin help suppress the inflammatory hormone production and the dopamine, serotonin and GABA nervous function regain their strength and control.
These processes will take about 7-10 days since the testosterone and DHT production in the post-ejaculation rely on the adrenal glands, skins, brain and internal organs, but not on the testicular function for exhausted persons
