Noun encyclopaedia of _ andrology of ketone of testis
Testis ketone most important man sex hormone ' Androgen) ,Mainly secreted by the testis.
Testis ketone ( Also called cortisol, testis ketone or testosterone) It is hormone of firm alcohol of a kind, secreted by the ovary of male testis or women, the renal gland also secretes a few testis ketone. It is sex hormone of main man and assimilates hormone. No matter man or women, it and has important influence to the health, including strengthening efficiency such as sexual desire, strength, immunological function, opposing osteoporosis. The statistics show, the weight that adult men secrete ketone of testis is 20 times that of adult women's secretion quantity.
Like other steroids hormone, ketone of testis is derived by cholesterol. Can last a large number of testis ketone testises male,woman ovary, placenta, man or the renal gland tapes netteds of women can secretion the testis ketones of small quantity.
Testis ketone to combine globulin, transport the intersection of goal and organization of body to via sex hormone in the blood. Cells of Sene and Tory in the male gonad need ketone of testis to turn into the sperm.
What function does sex hormone have in the man
In the past dozens of years, people have been thinking all the time estrogen can only play a very limited role in man's physiology, because its density in man's blood is very low. But the research in recent years shows, role in man of estrogen is very important in fact. The researchers (Nature, Vol 390, December of 1997) of U.S.A. Illinois State university Find, the little mouse of transgenic great ambition lacking the estrogen receptor in the testis loses reproduction ability, the actual reason is that estrogen has serious absorption on liquid, lack estrogen to make the seminal fluid stop up. This kind stop up, blockade the intersection of sperm and person who produce, reduce sport of sperm, inhibit the intersection of sperm and maturity of cell. Estrogen has other important function: If the man can't produce estrogen, then the long bone will have grown all the time, cause the body to unusually increase; While belonging to in some kinds, estrogen has certain function on forming and behavior of the man's mating behavior. Because androgen can be turned into estrogen through the complicated route, androgenic function can be said and " hit two hawks with one arrow " .
Ketone of testis, to the brain, the function of behavior and mood
Ketone of testis develops some areas of brain in embryo one and infancy, thus influence the development of the brain. In adolescence, with the increase of the density of sex hormone, structure of these brains and all behavioral skills can take shape formally.
To the direct intervention of sex hormone ' Research) Indicate, androgen has important function on the cognitive function. Castration man, kind does not have testis disease man and old man to use ketone of testis, increase their aware glimmering or vibrant ability (this is a method to measure attention and vigilance) ,And so long as offer the treatment androgenically, this kind of improvement can keep. Therefore, can be thought rationally, androgen is to person all one's life, from borning to grow up until the cognitive ability of the old age was playing a role in activating.
Attack the sexual behavior and is very correlated with with endogenous testis ketone level the grading oneself of the attack.
The relation about mood and between androgen is not very clear. The early report regarding castration man and gonad function bow the man finds, the testis ketone treatment stablizes its mood.
Some discover, the testis ketone treatment produces stronger aggressiveness than placebo. It is reported, the man of the gonad with low function supplements and treats ketone of testis, not merely improve the parameter of mood, such as energy and health sense, and reduce the parameter of bad mood, tense and irascible. The research proves, ketone of testis has some function on the man's mood and behavior. Some authors think, the function on the central nervous system of ketone of testis has not been totally clarified yet, because the human behavior receives social usage and normal complicated influence.
Ketone of testis and cardiovascular system
Ketone of testis and coronary heart disease (CHD.coronary heart disease) Between what does it have to do with?
Take off hydrogen watch grand ketone (DHEAs, sulfo-dehydroepiandrosterone) about ketone and sulfuric acid of testis Epidemiology and clinical research of the relation with CHD announce, endogenous androgen is neutral in man's body, even resist a kind of sclerosis function of porridge, but present and urge to resist a kind of sclerosis function of porridge in woman's body. Similarly, the other source testis ketone and DHEAs presents on a kind of sclerosis of porridge of the male animal too neutrally or benefits function, but present harmful function in the female animal's body.
Some discover ketone of testis reduces cholesterol (HDL-C) of high density lipoprotein The level, and others discovers the ketone of testis is to lipoprotein (a) ( Lp(a) )Present beneficial function. Some author find testis ketone make low the intersection of density and lipoprotein cholesterol (LDL-C) The level is reduced, and not found Lp(a) The level changes.
Besides lipoprotein supersession, some other factors, such as blood flow volume, the changes of the heart, blood vessel smooth muscle and blood coagulation system will influence the function on heart disease of ketone of testis from front or reverse side.
The materials which synthesize all reports can be thought, the man carries on the testis ketone treatment, will not generate a bad impact on main fat supersession and influence.
Study testis ketone level and coronary artery disease relation the materials indicate recently between the intensity, testis the intersection of ketone and level bow the intersection of blood and disease, might preceded a dangerous factor, form of atherosclerosis actually.
For confirm other source testis ketone supplementary to treat, have bad function to lipoprotein supersession, need to carry on the large-scale and more detailed long-term follow-up study.
Ketone of testis and skeleton
What relations are there between ketone of testis and skeleton?
Ketone of testis inhibits the bone of broken bone cells from absorbing, may stimulate into bone cells and take shape, especially the bone of cortex under the periosteum. The intersection of testis and product of supersession of ketone, especially estrogen, may androgen to main modulator that skeleton apply.
Osteoporosis is comparatively common in the man, it is a main dangerous factor of man's osteoporosis that the gonad function is low. Pass excited pharmaceutical (GnRH-a) of gonadotropin Excise treatment or testis, the osseous density drops rapidly, this may prove, the body of gonad steroid has important function in maintaining the osseous density. A lot of findings about the middle-aged and old man, the testis ketone treatment can reduce biochemical index of absorbing respect of the bone, and raise the ossicle density of bone of cortex and bone Xiao Liang.
Ketone of testis substitutes and treats the influence made up to the health
Muscles are an important target organ of ketone of testis, 5a reductase level in the muscle is very low. The adult man of the gonad with low function adopts ketone of testis to supplement and treat, enable health muscle quantity increase, muscle strength increases too, the fat of body is reduced, the body density increases. When study in a lot of, it may be unanimous for health to make up the discovery of exerting a favorable influence about the androgenic treatment. With old and feeble, upper part of the body and fat in the body increase, and muscle quantity and strength reduce. A lot of research regarding the middle-aged and old man used ketone of testis indicates, ketone of testis makes the muscular tissue increase, fat quantity is reduced; Grip and lower extremities strength increase at the same time.
Ketone of testis and sex
The male sexual behavior relates to androgen. When the testis begins to secrete androgenically in adolescence, the male sexual behavior begins to sprout and strengthen.
It is reported, the other source uses the man's sexual desire that ketone of testis increases the gonad with normal function, and strengthen the normal young man's hardness that the penis erects at night. Androgen may be right to be vigorous to play a organizing directly role.
Gonad function bow man carry on testis ketone supplementary to treat, indicate testis the intersection of ketone and some in sexual behavior have important function.
Impact on prostate of ketone of testis
Hyperplasia of benign prostate (BPH, benign prostatic hyperplasia) It is the middle-aged and old man's common disease with prostate cancer. Androgen might have facilitation to two disease these, androgen inhibit from come, treat two disease these. However, the blood plasma prostate -specific antigen of measurement carried on in the elderly, most research in parameters such as the size of prostate or urine flow,etc. have already shown, the testis ketone treatment does not influence these parameters.
