Abstract
The sexual decline in the elderly is caused by a decrease in the excitability threshold of erogenous zone receptors, including those in the brain.
In the case of analyzers, the state of sexual arousal is determined by neuro-psychic factors sensitized by visual, auditory, olfactory and tactile stimuli. The body shapes that confer the female’s sensuality are received by the male through the visual analyzer (Fig.1), the most important and sophisticated of the senses, having a special role in the appearance and potentiation of the erogenous sensation, respectively of libido.
It is well known that the visualization of the woman’s exciting corporeal forms easily may induce a state of arousal in the young man, the penile erection and the desire to mate, while in the elderly, due to the analyzers’ pathology (i.e.- the optic nerve), the erection does not appear or it occurs with difficulty and low erectile tone.
