Testosterone 5 alpha reductase

5-alpha-reductase inhibitors are a group of medicines that block the action of 5-alpha-reductase, the enzyme that converts testosterone into dihydrotestosterone. This results in increased levels of testosterone and decreased levels of dihydrotestosterone; an overabundance of dihydrotestosterone has been implicated in benign prostatic hyperplasia (BPH) and prostate cancer. The scalp of men with androgenetic alopecia (male-pattern baldness) has also been found to contain increased amounts of dihydrotestosterone and miniaturized hair follicles compared with men who have a lot of hair.

The second isoenzyme of 5α reductase is deficient in the classic intersex condition ( pseudovaginal perineoscrotal hypospadias ), or 5α-reductase deficiency . It was first discovered in indigenous cultures of Papua, New Guinea , where children were born with feminine genitalia in the absence of endogenous DHT during pregnancy, but with the surge of testosterone during adolescence, changed to males at puberty. Because of this change at puberty, the condition is also sometimes called " guevedoche ." [24] There is a range of external appearance that has been described of external genitalia at birth, with varying degrees of virilization.

We describe a simple procedure for the microassay of testosterone 5 alpha-reductase in homogenates of rat brain. This enzyme converts testosterone to dihydrotestosterone. We have used this assay to characterize the enzymatic activity and to map its distribution. The apparent Km is x 10(-6) M and the Vmax is pmol/mg protein/h. The pH optimum is broad and extends from pH to . For the brain regions surveyed, testosterone 5 alpha-reductase activity varied over a 10-fold range. The highest activities were observed in homogenates of the midbrain and pons (37-39 pmol/mg protein/h). The lowest were seen in homogenates of the thalamus, caudate nucleus, frontal cortex, hippocampus, hypothalamus, olfactory tubercle, and preoptic area (3-7 pmol/mg protein/h).

You need the energy to work out in the gym. If you do a job, that becomes very difficult for you to keep the same energy required for the exercise. Alpha Hard Reload gives you that power. Every man has particular desires and needs. He wants to look attractive with right body muscles, and he wants to be healthy. Both are things that are vital for men, and they also desire for a beautiful body shape. Also, men want to be right in bed so that they can satisfy their life partner. But due to less energy content in the body, it becomes hard to perform well in bed.
