In the extinction of sexual function, the endocrine system and the central nervous system are of primary importance. In the period of involution, atrophy of not only the gonads, but also the adrenal cortex, pituitary, thyroid and other glands, and the involution of some organs occur.

The weakening of sexual function occurs at the age of 50–70 years, in most men it fades away on average, about 55 years.

In most cases, male menopause is accompanied by a decrease in sexual ability and sexual feelings. Libido is weakening, the nature of libido is changing – the tinge of urgency, irresistibility is lost.

The men themselves say that before they could not find a place for themselves from an irresistible desire for sexual intimacy, but in the period of involution they look at a woman with a “chilled” look, admiring her beauty, but without the previous “burning”; if earlier they were not able to restrain themselves when a sexual attraction to a woman arose, now they can restrain themselves as much as they like and sometimes try to stimulate their sexuality and activate their desire to have sexual intercourse with their wife at least once a week.

According to doctors, in the involutional period there is a loss of psychophysiological integrity in experiencing a situation of intimate rapprochement.

If in young years even a spontaneous (spontaneous) morning erection was accompanied by erotic fantasies, and when communicating with a woman even in a situation excluding intimacy, a man could have an erection and desire for intimacy with this woman, then with the beginning of the involutional period, the man may experience a feeling of gratitude to a woman and show your love for her with caresses and kisses without causing an erection.

That is, one of the characteristic signs of the onset of the involutional period is the need to expend certain efforts to arouse the desire for intimacy and activate the remaining components necessary for the implementation of sexual intercourse, to “pull up” either the emotional mood to erections or erections to the emotional mood.

If the erection is delayed, the most frequent (and most physiological) method is to lengthen the stage of preliminary caresses, and then increase their intensity and use some additional techniques – sexual intercourse with the lights turned on to see a partner, using new postures for sexual intercourse, expanding the range of manual (with with the help of hands) manipulations on the penis by either the man himself or the woman.

If on the contrary, an erection is sufficient, but there is no emotional interest, and this is manifested in the difficulty of switching from everyday and official worries to a sexually-erotic mood, men use additional irritants – reading erotic literature, watching erotic or pornographic films and photographs.

In the period of involution, the nature of sexual abstinence also changes. Partial abstinence is possible, which may be accompanied by emissions, petting, and complete abstinence with the loss of subjectively painful feelings from forced abstinence, which was characteristic of earlier.

Menopause is accompanied by a gradual decrease in spermatogenesis (sperm production). Sperm cells become less mobile and change.

However, there are cases when, in the presence of menopause, a man retains sexual activity.

Jacobson believes that it is impossible to indicate the age at which men who have retained their sexual strength would not have met.

Psychologically involutional decrease in sexual activity of men is experienced much more painfully than women. This is one of the common disorders for which men turn to sex therapists.

In single people who do not have the ability to have regular sex, menopause is more difficult than in people who have a family and regular sexual intercourse. First of all, it affects the mental disorders characteristic of the menopause.

And many men who have lived a harmonious sex life and who are in a successful marriage with a wife of about the same age or a little younger age, quite calmly and reasonably endure the age-related decline in their sexual abilities. By the time of the period of involution, their value orientations are shifting towards other life values.

They do not come to the sex therapist because they know that the decrease in sexual capabilities and sexual needs is quite natural and physiological.

Such a harmonious entry into the period of involution is observed in those men who had normal psychosexual development and normal puberty. They started sexual activity in a timely manner, not earlier than no later than average age norms, regularly had sexual life, and they had no internal deficiency.

According to scientists, the harmonious entry into puberty largely determines the harmonious way out of the reproduction period.

And a completely different thing in people with delayed puberty. They are much later than the age norms (by 4–5 years) begin sexual life, much later their sexual activity becomes regular, and the period of decline in their sexual capabilities begins much earlier than the age norms.

The duration of the conditionally physiological rhythm period in such men is almost three times shorter than in normal men.

Sexopathologists note that although the patient himself dates the beginning of the decline in sexual abilities to a certain age, the survey reveals that violations firstly started much earlier, and secondly, there were indisputable signs of sexual deficiency from the very beginning of sexual activity, so that the true prescription of sexual failure is calculated not several years, as the patient himself believes, but 15–20, and sometimes 40–50 years.

Throughout life, the crisis periods of sexuality have to be overcome by all people, but among retardants (people with retarded sexual development), they are more pronounced, taking sharp forms both at the onset of sexual activity and during a period of decreased sexual activity.

The most pronounced are disorders in combination with a deep degree of delayed sexual development with congenital personality abnormalities.

The first signs of decreased sexual activity in patients with delayed sexual development may occur at the age of 28 years, some patients turn to sex therapists at the age of 36 years.

The average age of contacting a sexopathologist, according to the scientific and methodological center for sexopathology, is 50 years. The main complaints of patients – erection failure – 49%, weakening of sexual desire – 30%, ejaculation and orgasm disorders – 16%, acceleration of ejaculation – 5%.
