Testosterone functions within the brain. There are several lines of evidence for this: there are androgen receptors within the brain; testosterone is converted to both dihydrotestosterone (DHT) and estradiol by the actions of 5-α-reductase and aromatase respectively in the brain; steroid hormones promote neuronal cell growth and survival (Azad et al 2003). Testosterone enhances cerebral perfusion in hypogonadal men and that perfusion takes place specifically in Brodman areas 8 and 24, regions of the brain that are concerned with: strategic planning, higher motor action, cognitive behaviors, emotional behavior, generalized emotional reaction, wakefulness and memory (Greenlee 2000; Azad et al 2003). Studies of cognition demonstrate that older men with higher levels of free testosterone index (a surrogate measure of bioavailable testosterone) have better scores in tests of: visual memory, verbal memory, visuospatial functions and visuomotor scanning. Hypogonadal men have lower scores in tests of memory, visuospatial function, with a faster decline in visual memory (Moffat et al 2002). In a very small, short term placebo-controlled study hypogonadal men with Alzheimer’s Disease (AD) treated with testosterone demonstrated a modest improvement in a cognition assessment score in AD (Tan and Pu 2003).

4. Foods rich in vitamin A. Vitamin A is more commonly known for its association with eyesight improvement, but it is also a vitamin supplements the production of testosterone. The June 2004 issue of the Clinical Endocrinology journal published research conducted by Israel’s Kaplan Medical Center. This study involved Israeli boys that had delays in puberty. These boys were given Vitamin A supplements and foods rich in Vitamin A over the course of 6 months, and most of them showed an improvement with their testosterone levels. If you want to boost the level of testosterone in your body, food types that are rich in Vitamin A are carrots, sweet potatoes, squash, cantaloupe and eggs.

Other Potential risks that can be caused by use of testosterone supplements are: People who take good testosterone supplements or any other kind of testosterone boosters can also experience many other side effects, including stomachache, problems with urination, dizziness, mood changes, intermittent breathing during sleep, changes in testicles, appetite loss, inflammation of gums, weight gain, nausea, painful erection, and protracted erection.


You can search every supplement on the market, and you can try reading “how to be good at sex” books (there’s about a million of them); You can even try those strange penis exercises (please do not waste your time). Or you can take a daily supplement that is designed and developed to do one thing: transform your penis and sex life so the next time a girl is talking about some guy who “could not stop making me orgasm,” that guy is you!

Growth of spermatogenic tissue in testicles, male fertility, penis or clitoris enlargement, increased libido and frequency of erection or clitoral engorgement occurs. Growth of jaw, brow, chin, and nose and remodeling of facial bone contours, in conjunction with human growth hormone occurs.[21] Completion of bone maturation and termination of growth. This occurs indirectly via estradiol metabolites and hence more gradually in men than women. Increased muscle strength and mass, shoulders become broader and rib cage expands, deepening of voice, growth of the Adam's apple. Enlargement of sebaceous glands. This might cause acne, subcutaneous fat in face decreases. Pubic hair extends to thighs and up toward umbilicus, development of facial hair (sideburns, beard, moustache), loss of scalp hair (androgenetic alopecia), increase in chest hair, periareolar hair, perianal hair, leg hair, armpit hair.

Herbalists have used _Trifolium pratense_, red clover, to treat menopausal symptoms like hot flashes. The mechanisms underlying these effects remain unknown. Testosterone decreases hot flashes in some postmenopausal women, so red clover may work in this way. A 2015 paper in the Avicenna Journal of Phytomedicine reviewed the literature testing this idea.

The reliable measurement of serum free testosterone requires equilibrium dialysis. This is not appropriate for clinical use as it is very time consuming and therefore expensive. The amount of bioavailable testosterone can be measured as a percentage of the total testosterone after precipitation of the SHBG bound fraction using ammonium sulphate. The bioavailable testosterone is then calculated from the total testosterone level. This method has an excellent correlation with free testosterone (Tremblay and Dube 1974) but is not widely available for clinical use. In most clinical situations the available tests are total testosterone and SHBG which are both easily and reliably measured. Total testosterone is appropriate for the diagnosis of overt male hypogonadism where testosterone levels are very low and also in excluding hypogonadism in patients with normal/high-normal testosterone levels. With increasing age, a greater number of men have total testosterone levels just below the normal range or in the low-normal range. In these patients total testosterone can be an unreliable indicator of hypogonadal status. There are a number of formulae that calculate an estimated bioavailable or free testosterone level using the SHBG and total testosterone levels. Some of these have been shown to correlate well with laboratory measures and there is evidence that they more reliably indicate hypogonadism than total testosterone in cases of borderline biochemical hypogonadism (Vermeulen et al 1971; Morris et al 2004). It is important that such tests are validated for use in patient populations relevant to the patient under consideration.

2. Garlic. According to a research conducted by the Kobe’s Women’s University, an increase in the intake of garlic can actually enhance the testosterone level of the body, given that garlic is also complemented with a high protein diet. A compound called the diallyldisulfide can be found in garlic, and this compound is responsible for producing the testosterone stimulating hormone (TSH).  This is an aptly named hormone.
