<prompt> Fingqa isihloko: Kuwukukhathazeka okudala kwabesilisa emhlabeni wonke. Nokho, manje ososayensi baye baveza lokho okubhekwanjengokuvamile ngobukhulu nobude bepenisi. Bathola ukuthi ubude obuphakathi nendawo besitho sangasese sobulili esivukile bungamasentimitha angu - 13,12. Ngakolunye uhlangothi, ubude obuvamile besitho sobulili esixegayo bungamasentimitha angu - 9,16 kanti uma sixegayo kodwa siluliwe singamasentimitha angu - 13,24. Futhi ngokuqondene nobubanzi, ububanzi obuphakathi nendawo lapho iqondile babungamamitha angu - 11,66 kanti uma iqondile kwakungamamitha angu - 9,31. Ucwaningo lwaseBrithani lwathola nokuthi kunokuhlobana okuncane phakathi kobude besitho sobulili esimi ngomumo nobude besilisa. Abacwaningi bathole ukuthi ubude besitho sangasese sobulili esixegayo bungu-3.6 inches 9.16 cm no-5.2 inches 13.24 cm lapho sixegayo kodwa siluliwe ifayela lesithombe Abacwaningi bathi amagrafu abawabhalile, abonisa ukusatshalaliswa kosayizi wesitho sangasese sobulili, azosiza odokotela ababhekene ne-Body Dysmorphic Disorder BDD, isifo sokukhathazeka esibucayi esihlobene nesithombe somzimba. Lolu cwaningo lungasiza ekululekeni amadoda akhathazekile ngosayizi wawo, noma ekuphenyeni ukuthi ukwehluleka kwama-condom kuhlobene kanjani nosayizi nobubanzi bepenisi. Amanye amadoda akhathazwa ubukhulu bepheni lawo, futhi lawo akhathazekile futhi acindezeleke kakhulu angase atholakale ene-BDD. Abacwaningi bakha igrafu noma i-nomogram ebonisa ukusatshalaliswa kosayizi we-penis phakathi kwamadoda akubo bonke ubudala nezinhlanga eziningi. Lolu cwaningo lwaluhlanganisa izifundo ezingu - 17 zamadoda angu - 15 521 ayehlolwa ubukhulu bepenisi ochwepheshe bezempilo besebenzisa inqubo evamile. Ngaphambi kwalolu cwaningo, kwakungakaze kube khona ukubuyekezwa okuhlelekile kwalezi zilinganiso, futhi kwakungekho mzamo wokwenza i-nomogram ebonisa ukusatshalaliswa kosayizi. Umbhali oholayo uDkt. David Veale we-Institute of Psychiatry, Psychology Neuroscience IoPPN, i-Kings College London neSouth London kanye ne-Maudsley NHS Foundation Trust, watshela i-MailOnline: Amadoda aziqhathanisa nezithombe zobulili ezingcolile ezitholakala kuyi-Internet futhi akholelwa ukuthi angaphansi. Abanye abesilisa baye bahlekwa usulu abalingani babo bobulili ngobude babo. Kunamadoda amaningi...  <response>: Ochwepheshe baye bakha amagrafu abonisa ukusatshalaliswa kosayizi wepenisi. Ucwaningo lubonisa ukuthi ubude besitho sangasese sobulili esixegayo bungamasentimitha angu - 9,16. Lokhu kufinyelela kumasentimitha angu - 13,24 uma kunwetshiwe kodwa kusalokhu kuqothukile. Abacwaningi bathole ukuthi kunokuhlobana okuncane phakathi kokuphakama nobude bepenisi. Ochwepheshe bathi amagrafu angasiza odokotela ekwelapheni i - Body Dysmorphic Disorder.
