Sexual Differentiation And Ageing – The Broken Hypothalamic-pituitary-gonadal Axis

Sexual Differentiation And Ageing – The Broken Hypothalamic-pituitary-gonadal Axis

Sexual differentiation becomes more fuzzier when we grow older and older.
Male sexual differentiation is gone when the androgen hormone receptors in the hypothalamus-pituitary androgen hormonal feedback control loop are degenerated or become insensitive. That is, the hypothalamic-pituitary-gonadal axis is broken. Under this condition, the pituitary LH hormone remains low when the testosterone level is low. If The hypothalamic-pituitary-gonadal axis is still active, the pituitary gland will overshoot LH release in response to low serum testosterone. As a result, men will experience the so-called male “menopause” (andropause) symptoms produced by excessive LH, such as anxiety, sweating, sleeping disorder, mood swing, hot flushes, and so on, like women do in the midlife. The simplest pharmaceutical solution for male and female menopause symptoms is to break/castrate the hypothalamic-pituitary-gonadal axis with SSRIs antidepressants, that is to degenerate or desensitize the sex hormone receptors (testosterone receptors for men, or estrogen receptors for women) in the hypothalamus-pituitary axis. Breaking the hypothalamic-pituitary-gonadal axis will disable the sex hormone feedback control loop in the hypothalamic-pituitary-gonadal axis, so that the pituitary gland won’t release excessive LH in an attempt to reactivate the testicular/ovarian function. Thus, SSRIs performs chemical castration of the hypothalamic-pituitary-gonadal axis. A good or bad idea?
Therefore, old men become femalized (grow the breasts and shrink the penis), and lose muscles, bone density and manhood. Old men will no longer have to worry about erection or penile enlargement!.

Man, DHT (Dihydrotestosterone) grows your penis during your puberty and maximizes your erectile size during age 20-30 when it reaches the peak level, but causes no problems for your prostate. When you get older and your DHT level starts to drop, you start to experience prostate enlargement, even cancer!
https://www.jstage.jst.go.jp/…/endocr…/24/1/24_1_41/_pdf
What is wrong? DHT grows everything, but why does your prostate cell become inflammatory and change itself to cancerous cell? Biological clock onset of cancerous genes? The clock is ticking if you carry the gene. Can you silence the gene (clock)?
Yes, reduce cellular prostaglandin E2 (PG-E2) release. PG-E2 activates stem cells (good or bad/cancerous) to multiplicate the cells and to grow the bone/brain. This is why you have growing pains.

Although Prostaglandin E2 starts your life by allowing a sperm to fertilize an egg (disabling the egg immunity), lets you get out of the uterus (uterine ripping for childbirth) and grows your body (stimulating your cell, brain, memory, and bone growth), it can end your life with infection, inflammation, fever, immune disorders and cancers. During your puberty, it lets you experience growing pains. After you pass puberty, you should reduce/adjust your cellular prostaglandin E2 release, so that it won’t activate cancerous DNA for you.

Prostaglandin E2 can be induced by mechanical stretching of muscles, tissues or bones. For example, stretching boned promotes bone growth via prostaglandin E2. This principle has been used for manhood enlargement exercises or stretching. Over-stretching tissues (including erectile tissues and smooth muscles) generally stimulate the collagen protein release for tissues scaring. The tissue scarring can extended to compress the nerves and blood vessels in addition to stretching induced nerve and blood vessel damage or scarring. You should avoid mechanically stretching damage of the nerves, tissues and blood vessels, upregulate your DHT and 5-alpha reductase receptors in your erectile tissues, increase your hGH production to activate the penile somatic stem cells, boost the release of beta endorphin, and activate the genes cytokeratin 16 and transformation growth factor beta-3 for enbryonic scar-free healing and cellular growth (http://action.love/cases/case11311.htm )!

How Does Aquila Anal-Breathing (Altair) QiGong Exercises boost your brain and endocrine function?

Aquila Qigong practices increase sex hormones  via the stimulation (stretching/compression, twisting, or/and contraction, even light or thermal )  of  the local peripheral hormonal target tissues ( extragonadal ) which have sex hormone receptors (as intracrinology, http://www.ncbi.nlm.nih.gov/pubmed/1838082, andhttp://www.ncbi.nlm.nih.gov/pubmed/1314080) , as well as the stimulation of the central  hypothalamicpituitarygonadal axis (also HPG axis) known as the neuro-endocrine function  – http://www.uthsc.edu/endocrinology/documents/ch08-syllabus-Childress.pdf.

17 beta-hydroxysteroid dehydrogenase is a group of the liver Cytochrome P450 alcohol oxidoreductases, responsible for catalysing the dehydrogenation of 17-hydroxysteroids in steroidogenesis  that includes interconversion of DHEA and androstenediolandrostenedione and testosterone, and estrone and estradiol, respectively,  as shown in http://upload.wikimedia.org/wikipedia/commons/1/13/Steroidogenesis.svg.

The intracrinologic function takes effect in about  5-10 minutes after starting exercising, while the neuro-endocrine function kicks in after taking a rest.

My theory about the exercise effects on the nervous function, skin/muscle endocrine function (aslo known as intracrinology – steroidogenesis in peripheral intracrine tissues – http://www.ncbi.nlm.nih.gov/pubmed/1838082,  http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3710002/pdf/11-14.pdf , http://physrev.physiology.org/content/physrev/88/4/1379.full.pdf  and http://www.medizin.uni-tuebingen.de/transfusionsmedizin/institut/eir/content/2004/42/article.pdf  ) , and neuroendocrine function is:

1. Somatic motoring nerves activates the cells in the muscles for the skin and muscle endocrine function (steroidogenesis) with the liver P450 enzymes, leading to syntheses of hGH, DHEA, testosterone, DHT and neurotransmitters and their precursors (Sunlight UV stimulates the skin endocrine function too), for examples: http://www.ncbi.nlm.nih.gov/pubmed/8092980http://www.ncbi.nlm.nih.gov/pubmed/23435015 ,http://www.ncbi.nlm.nih.gov/pubmed/22166417, http://www.ncbi.nlm.nih.gov/pubmed/24464446 & http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3847208/pdf/1471-2369-14-194.pdf , http://jap.physiology.org/content/96/2/531.full.pdf+html, http://www.ncbi.nlm.nih.gov/pubmed/15942766;

2. Stretching or twisting of nerves, blood vessels and muscles generates the somatic sensory nervous signals, partially to autonomic nervous reflex arcs in the spine and the medulla oblongata for steroidogenesis of internal smooth muscles, activation of the neuroendocrine function, and partially to the thalamus (via the somatic sensory pathway of the Thalamus) for activation of the central nervous system ,
for examples:
http://www.ncbi.nlm.nih.gov/books/NBK10950/ ;http://www.ncbi.nlm.nih.gov/pubmed/11240404 and more in References). Note: some researcher have shown that “a role of skeletal muscle as a secretory organ of cytokines and other peptides, denominated myokines (IL6, IL8, IL15, Brain-derived neurotrophic factor, and leukaemia inhibitory factor), which have autocrine, paracrine, or endocrine actions and are deeply involved in inflammatory processes” ( http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3710002/ and http://physrev.physiology.org/content/physrev/88/4/1379.full.pdf ).

You can boost your growth hormone level over 300 % before a meal in 30 minutes. The best time to jump your hormonal level up is before breakfast.  However, you should limit your exercise duration for no longer than 60-80 minutes – http://jap.physiology.org/content/96/2/531.full.pdf+html . According this report, you can increase your testosterone level at about 20-30%. Our reader also reported this result.

exercises-induced endocrine functionHowever, prolonged, heavy-duty, hard-core exercises usually burn out your testosterone faster than your body produces ( http://jap.physiology.org/content/96/2/531.full.pdf+html ). In addition, the hypothalamus and adrenal glands turn dopamine to norepinephrine, and then, when the dopaminergic system runs down in the exhaustion state, the pituitary gland releases excessive prolactin; as a result of combination of both norepinephrine and prolactin, norepinephrine is bound into the sympathetic nervous alpha receptors to tighten up your muscles and arteries, and the cells in the joints and muscles release excessive prostaglandin E2 for pain to set the alarm off – ( http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3766664/ ; http://www.ncbi.nlm.nih.gov/pubmed/22151605 ; http://www.ncbi.nlm.nih.gov/pubmed/10090630 ; http://www.ncbi.nlm.nih.gov/pubmed/15942766).

At this stage, there s a lack of blood flow to your brain and testicles; thus, your testicular function slows down and produces less testosterone. Therefore, you will have a longer and longer recovery time. You may grow your muscles at the expense of your testicular (or ovarian for female ) function –

Orgasm , Histamine Receptors ( H1, H2 and H3) , and Premature Eejaculation

Orgasm releases extra histamine by mast cells under the stimulation of norepinephrine due to an rapid conversion of dopamine-to-norepinephrine in the hypothalamus and adrenal glands during sexual encounter and even after orgasm.
The solution is: reduce abrupt dopamine-norepinephrine conversion, and inhabit its action on the adrenergic alpha receptors.

The receptors affected by histamine are given below.  H2 seems producing positive effects, but H1 can give you positive and some negative (such as itching, asthma, pain, dizziness, an so on) effect,  and H3, which serves as a feeback control of norepinephrine release but also negatively inhibit acetylcholine and serotonin release in the CNS for memory loss, depression and weak cholinergic/vegas and serotonin nervous control.  Thus, H1 and H3 receptors generate sexual exhaustion symptoms, although H1 receptors in the vaginal endothelial cells (particularly, around the G-spot) triggers the orgasm responses for the vagal nerves, and in the prostate, urethra, bulbourethral,  and seminal vesicles, it produces hypersensetive sensation and induces ehaculation urgency premature ejaculation or precum/semen leakage during sexual encounter .

Premature ejaculation is a very complicated tissue.
Main possible causes:
1. The prostate abrasion and poor seminal quality due to over-masturbation.
It requires a long-term prostaglandin E-1 therapy with Viapal-hGH-J (3-015) and 5-HTP (2-001) ,  plus Fish oil  (2-005) and Vitamin D(2-004) daily.

2.  Drug abuse.
It requires a long-term nervous detoxification with Viapal-hGH-J (3-015) , DeToxiA (1-017) and 5-HTP (2-001), plus Fish oil  (2-005) and Vitamin D(2-004) daily.

3.  a low  Serotonin level in the brain.
MoodMax and 5-HTP can help
4.  over-training of the nervous L1-L3 reflex arcs  of the PC and prostate muscles.
a long term Anal breathing practice can solve the problem

5.  weak erection.
Power your erection with Viapal-hGH-J (3-015)

We use 5-HP,  ViaGrowth-III (or ViaGrowth-IV)+ MoodMax + DopaFIbra, Fish Oil (Omega-3 EPA  (647 mg) and Vitamins D 2000 IU and E 200 IU.
5-HTP + MoodMax + EPA  boost the cholinergic,  serotonin and GABA nervous control in the hypothalamic dopamine-norepeinephrine conversion, and power the parasympathetic nervous function to counterbalance  the sympathetic nervous function.
Our 5-HTP also contains a high dose of B3 (Niacin) to increase prostaglandin D2 production for relax the blood-brain tight junction for brain and nervous nutrients to penetrate into the brain and nervous system. Prostaglandin D2 also dilates arteries and capillaries for better blood circulation. B3 also increases the serotonin synthesis.
DopaFibra + ViaGrowth-III increase androgen hormones,  charge the central  dopaminergic nervous system and the parasympathetic nervous system,  and block the adrenergic alpha receptors, so that norpeinephrine and epinephrine can stimulate the adrenergic beta receptors for arterial dilation,  more blood https://www.rossitchpediatricdentistry.com/buy-lasix-online/ flow and beta-endorphin release.   Beta-endorphin in the brain and semen can cool down the sympathetic nervous function.
Fish Oil, Vitamins D and E will also increase testosterone and semen production.  They also change the semen chemistry by increasing prostaglandin E1 and E3 while reducing prostaglandin E2.
Reducing the sympathetic nervous function, increasing beta-endorphin/acetylcholine/serotonin/GABA/prostaglaninds E1/E2 and nadrogen hormone testosterone/DHT, and reducing norepinephrine/prostaglandin E2 will reduce histamine release.
Premature ejaculation, the sympathetic nervous fight response to sexual stimulation,  occurs when the prostate,  seminal vesicles, urethra, and  bulbourethral glands cook up more prostaglandin E2 and histamine, as inflammatory and sensitization hormones, in the synthesizing fluids (precum and semen)  under the sexual-induced excessive hypothalamic and adrenal dopamine- norepinephrine conversion.
We use the same formula to knock the bladder anxiety, over-reactive bladder, and stress induced incontinence.
There is another sympathetic nervous response to sex,  known as sympathetic nervous flight.  When the dopamine nervous function becomes too weak to stimulate the pituitary glands for sex, the pituitary gland releases insufficient oxytocin but excessive prolactin to constrict the arteries and retrieve the blood from the brain, penis and testicles, so that the penis goes limp.  The sympathetic nervous flight response to sex will force you to contract the PC muscles and the prostate to stimulate L1-L3 and S2-S4 for erection. Stimulation of L1-L3 sympathetic nerves activates the autonomic/sympathetic nervous reflex arcs in Discs L1 – L3 for precum release, semen emission and expulsion (ejaculation).
The solution for the sympathetic-nervous-flight-induced the sympathetic nervous fight is to block the autonomic nervous reflex arcs in Discs L1-L3 by my Anal Breathing training that alternates the autonomic nervous reflex arcs from L1-L3 to S1-S4.
Chronic masturbation for a fast ejaculation release usually trains the L1-L3 autonomic reflex arcs into a neuroplasticity state. If you got it, you have to ee-train your nervous reflex arcs.
