Testosterone cells

While I was doing my research one thing I was worried about right from the beginning was side effects and how safe testosterone boosters really are. After thoroughly researching the most common ingredients and most of the test boosters that currently exist I am happy to report that there are a very few on the market that are unsafe. These supplements by their very nature use only natural ingredients and can’t cause any natural side effects. There are generally no synthetic ingredients in most of the products currently on the market. However, a quick word of warning, I would stay away from any product that uses a “proprietary blend” and does not disclose its full ingredients list along with the exact dosages of each ingredient. Which brings me to my next point…

The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression". [77] [78] Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible. [77] The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game. [79] Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males. [80] [81] [82] [83] [84]

Although there is clear evidence that many women with low testosterone levels do not experience sexual dysfunction, there is also evidence that testosterone plays a role in regulating female sexual desire and response. For example, studies have correlated low testosterone levels in women with decreased orgasmic ability, sexual pleasure and reduced libido. There is also evidence that women’s response to sexual stimuli (. erotic videos, sexual contact) is increased and that women have sex more frequently, during the mid point of their menstrual cycle, at which time testosterone levels are highest and they are also most fertile. In addition, there is evidence that testosterone levels increase in response to sexual stimuli. For example, a study in which women masturbated to orgasm reported that the women’s testosterone levels increased after orgasm.
