Effect of Lepidium meyenii (maca) roots on spermatogenesis of male rats.
TLDR
The Lepidium meyenii root invigorates spermatogenesis in male rats by acting on its initial stages (IX-XIV), which results in an increase in the weights of testis and epididymis but not the seminal vesicle weight.
The effects of exogenous testosterone on sexuality and mood of normal men.
TLDR
It is concluded that supraphysiological levels of testosterone maintained for up to 2 months can promote some aspects of sexual arousability without stimulating sexual activity in eugonadal men within stable heterosexual relationships.
Lack of sexual activity from erectile dysfunction is associated with a reversible reduction in serum testosterone.
TLDR
Since the pre-therapy low testosterone levels were independent of the aetiology of impotence, it is hypothesized that this hormonal pattern is related to the loss of sexual activity, as demonstrated by its normalization with the resumption of coital activity after different therapies.
