Schimb\u0103rile climatice ar putea influen\u021ba sexul copilului t\u0103u, potrivit unui nou studiu citat de Daily Mail<\/a>. Cercet\u0103torii de la Universitatea Oxford au descoperit dovezi surprinz\u0103toare. Temperaturile mai ridicate par s\u0103 afecteze raportul dintre sexe la na\u0219tere.<\/p>\n

Echipa de la Oxford a analizat peste cinci milioane de na\u0219teri. Studiul a acoperit 33 de \u021b\u0103ri din Africa subsaharian\u0103 \u0219i India. Rezultatele au fost clare: temperaturile peste 20\u00b0C sunt asociate cu na\u0219terea mai multor fete.<\/p>\n

Dr. Abdel Ghany, autorul principal, a explicat importan\u021ba descoperirilor. \u201eC\u0103ldura extrem\u0103 nu este doar o amenin\u021bare major\u0103 pentru s\u0103n\u0103tatea public\u0103\u201d, a spus el. Cercet\u0103torul sus\u021bine c\u0103 temperatura influen\u021beaz\u0103 fundamental reproducerea uman\u0103.<\/p>\n

\u201eDemonstr\u0103m c\u0103 temperatura influen\u021beaz\u0103 cine se na\u0219te \u0219i cine nu se na\u0219te\u201d, a ad\u0103ugat Dr. Ghany. Constat\u0103rile arat\u0103 c\u0103 temperatura are consecin\u021be m\u0103surabile asupra supravie\u021buirii f\u0103tului. De asemenea, influen\u021beaz\u0103 comportamentul de planificare familial\u0103.<\/p>\n

Mecanisme diferite \u00een Africa \u0219i India<\/strong><\/h2>\n

Cercet\u0103torii au identificat mecanisme diferite \u00een cele dou\u0103 regiuni studiate. \u00cen Africa subsaharian\u0103, sc\u0103derea na\u0219terilor de b\u0103ie\u021bi este legat\u0103 de mortalitatea prenatal\u0103. Cauza principal\u0103 este stresul termic matern provocat de c\u0103ldur\u0103 extrem\u0103.<\/p>\n

\u00cen India, efectele apar mai t\u00e2rziu \u00een timpul sarcinii. Temperaturile ridicate \u00een trimestrul al doilea sunt asociate cu mai pu\u021bine na\u0219teri de b\u0103ie\u021bi. Efectul este mai pronun\u021bat la mamele mai \u00een v\u00e2rst\u0103 \u0219i la cele f\u0103r\u0103 fii.<\/p>\n

Ce \u00eenseamn\u0103 pentru raportul global \u00eentre sexe<\/strong><\/h2>\n

La nivel global, exist\u0103 u\u0219or mai mul\u021bi b\u0103rba\u021bi dec\u00e2t femei. Raportul actual este de aproximativ 101-102 b\u0103rba\u021bi la fiecare 100 de femei. \u00cenc\u0103lzirea global\u0103 ar putea schimba acest echilibru \u00een deceniile urm\u0103toare.<\/p>\n

\u201eExist\u0103 o reac\u021bie specific\u0103 sexului la temperatura dinaintea na\u0219terii\u201d, au concluzionat cercet\u0103torii. At\u00e2t reac\u021biile biologice, c\u00e2t \u0219i cele comportamentale joac\u0103 un rol important. Impactul asupra compozi\u021biei popula\u021biei ar putea fi substan\u021bial.<\/p>\n

\u0218i fertilitatea masculin\u0103 este afectat\u0103 de clim\u0103<\/strong><\/h2>\n

Un alt studiu, realizat la Universitatea din Manchester, aduce date suplimentare. Cercet\u0103torii au analizat probe de sperm\u0103 de la peste 15.500 de b\u0103rba\u021bi. Participan\u021bii proveneau din Danemarca \u0219i Florida, dou\u0103 climate complet diferite.<\/p>\n

Rezultatul a surprins chiar \u0219i pe oamenii de \u0219tiin\u021b\u0103. Calitatea spermei este cea mai bun\u0103 vara \u0219i cea mai slab\u0103 iarna. Acela\u0219i tipar a fost identificat \u00een ambele \u021b\u0103ri, indiferent de clim\u0103.<\/p>\n

\u201eAm fost uimi\u021bi de c\u00e2t de similar era modelul sezonier\u201d, a declarat profesorul Allan Pacey. Chiar \u0219i \u00een Florida, unde temperaturile r\u0103m\u00e2n ridicate tot anul, tiparele s-au repetat. Cercet\u0103torii cred c\u0103 temperatura ambiant\u0103 nu este singura explica\u021bie.<\/p>\n","protected":false},"excerpt":{"rendered":"
