The men resist better to pain

Exit, the knights without fright and without grimaces If the men are more resistant to pain, it would have got nothing to do with them fabled endurance, but rather everything to see with their hormonal system.

Far from being cosier, the women would not simply benefit from clean protection to the men: testosterone, a tremendous(great) buckler antipain!

« This hormone served undoubtedly at first for protecting the men of big somatic pain. The hunter who made eat an arm struggled for his survival », Isabel Gaumond advances(moves). The professeure of the department of the sciences of the health of the University of Quebec in Abitibi-T?miscamingue signs an exciting article on subject, Is the pain sexist? Endogenous mechanisms and sexual hormones, with Serge trader — the specialist of Quebec of pain — in the recent edition of the magazine Medicine / science. The key of the understanding of difference face d with pain would find a place to live so in the hormonal sphere.

While pain is part prenante of the life of the women (menstruations, delivery, etc), the men are better armed to make him(her) face. An injustice still aggravated(increased) by the private link which exists between menstrual cycle and chronic pain. « The threshold of pain is lower for the women and they support(bear) intense stimuli less. On top of that, they are more often victims of chronic pain linked up with menstrual cycles, such splitting headache », support the seeker who follows(continues) clinical plans within an interactionnelle school nowadays intended(designed) to help the patients suffering from cervical pain.

Painful experiments

To explore the mechanisms of pain, the researchers subjected rats to painful experiments. Renowned have a system of transmission of similar pain in ours, these animals are models improved for this type of studies.

Rats accepted(received) an injection of formaline — from some indistinct formalin — in the back leg. This injection gave them a badly persistent during two hours while the researchers noted(noticed) their reactions. They determined a sexual dimorphisme in the modulation of the different mechanisms of management of pain linked up with the nervous system. « The males seemed to be less displayed(explained) there than the females », raises Isabel Gaumont. While gonadectomis?s subjects — in the absence of sexual gland — produced the same answers as the females.

The biggest tolerance of the males in pain would come from influence of testosterone on excitateurs mechanisms which transmit the painful sign(signal). At the females, sexual hormones would play rather on inhibition – even if other mechanisms, as the release of endogenous opio?des, exist in the female management of pain. This hormonal difference s o proved to be less efficient at the women, especially during chronic pain.

The recent research works of the seeker Ana Maria Aloisi also go to this sense. The Italian seeker questioned transsexual on their perception of pain during the administration of hormones linked to the change of sex. Near a man becoming woman on three (29,8 %) brought back(reported) pain. A new reality for a transsexual on six!
