<prompt> Fingqa isihloko: Kungakhathaliseki ukuthi kusegumbini lokuhlangana noma endaweni yokuzingela, ukuncintisana kwabesilisa kungabangela ukwanda okungazelelwe kwamazinga e-testosterone. Manje ukuhlola okusha kutholile ukuhlobana phakathi kwe - testosterone nohlangothi olunakekelayo lwamadoda lapho ebuyela ekhaya ngemva kokuzingela. Lolu cwaningo lwembula ukuthi lapho i-testosterone yendoda inyuka kakhulu phakathi nosuku, yilapho ihomoni yothando i-oxytocin evame ukukhiqizwa kakhulu lapho ifika ekhaya. Lolu cwaningo lwalusekelwe kubantu abangamaTsimane, abantu bomdabu abalimi nabazingeli abahlala emathafeni aphansi esigodini sase-Amazon eBolivia. Abacwaningi bathi isimiso sama - hormone somuntu sivumelaniswe kahle kakhulu nendlela yabo yokuphila. Abacwaningi baphinde bathola ukuthi ukwanda kwe-oxytocin kwakukukhulu kulawo madoda ayekhishwe isikhathi eside. Lolu cwaningo lwalusekelwe kubantu abangamaTsimane, abantu bomdabu abalimi nabazingeli abahlala emathafeni aphansi esigodini sase-Amazon eBolivia. Abacwaningi bathi isimiso sama-hormone abantu sisebenza kahle kakhulu endleleni yabo yokuphila egxile emiphakathini emincane, ehlangene ngokuqinile ekhiqiza ukudla kwayo. Inhloso yethu kwakuwukubheka ukusebenzelana phakathi kwama-hormone ahlukahlukene ekukhuthazeni ukuziphatha esimweni esingokwemvelo, kusho u-Adrian Jaeggi, ongomunye wababhali abaphambili e-University of California, eSanta Barbara. Lolu cwaningo lwembula ukuthi lapho i-testosterone yomuntu inyuka kakhulu phakathi nosuku, yilapho ihomoni yothando i-oxytocin evame ukukhiqizwa kakhulu lapho efika ekhaya. Abacwaningi baphinde bathola ukuthi ukwanda kwe-oxytocin kwakukukhulu kakhulu kulabo bantu ababengekho isikhathi eside, futhi kwakuhlobene nokushintsha kwe-testosterone esithombeni Ukuzingela ukuze umuntu aphile nokuhlanganyela inyama yinto abantu abaye bayenza amakhulu ezinkulungwane zeminyaka. Ucwaningo lwangaphambili luye lwabonisa ukuthi i-oxytocin yenza abantu babambisane kakhudlwana kuyilapho i-testosterone inomphumela ophambene. UJaeggi wathi wayelindele ukubona ukuhwebelana phakathi kwamahomoni amabili futhi wamangala ukuthola ubuhlobo obuhle phakathi kwawo. Lapho indoda itshela umkayo noma...  <response>: Abacwaningi balandelela amazinga amahomoni abantu abangamaTsimane eBolivia. Ukuzingela ukudla usuku lonke kwabangela ukwanda kwamazinga e-testosterone. Lapho i-spike inkulu, yilapho indoda ikhiqiza i-oxytocin eyengeziwe lapho ifika ekhaya. Ukwanda kwe-oxytocin kwakukukhulu kulawo madoda ayekho isikhathi eside.
