DNA ubé madlozi

Iinkcukacha-manani zibonisa ukuba kwamanye amazwe kwiqondo ukungachumi ukunwenwa 8-29%, kwaye ehlabathini jikelele - 15%. Kwangaxeshanye yonke isibini yesibhozo akunakwenzeka ukuba ukukhawula umntwana wokuqala. Wonke pair lesithandathu kunzima ngokuzalwa loonyana kwesibini. Xa kwesiqingatha iimeko oku kungenxa yeengxaki wesini womelele, oko kukuthi, kukutshintsha parameters bembewu zeebhokhwe nangoku linegama elithi "DNA ubé". Kwiminyaka engamashumi amabini edlulileyo, olu phuhliso eyandayo: ukusuka-30 ukuya kuma-50%.

Ukuba kuyimfuneko, kwenza uhlahlelo olufanelekileyo, kuyimfuneko ukumisela neqondo DNA ukuqhekeka. Kodwa asinguye wonke umntu uqhelene kwikota ngasentla, kwaye unalo imibuzo emininzi. Ngoko kuyimfuneko ukuba uyivule ngakumbi.

Ntoni igama elithi "DNA ubé"?

Phantsi kwale nkcazelo, libhekisela iqondo umonakalo imisonto DNA, nto leyo sisalathisi umgangatho gametes kwaye uthetha malunga nenqanaba wenzala eyindoda. Izikhewu DNA kweleli kukhokelela kukuba ukuthembeka kolwazi yemfuza iphazamisekile. Ngenxa yoko, amathuba ukuzalwa yehla kakhulu.

DNA ukuqhekeka kaninzi kwenzeka ngenxa protamines ukuhla. Yinto a iiproteni ezizodwa ezifana zothutho, ziqulethwe zofuzo. Besenza umsebenzi omkhulu ukhuseleko - ukuthintela imisonto DNA ukusuka umonakalo obangelwe yimiba yangaphandle.

Ubukho ukuqhekezwa iDNA iiseli intsholongwane unempembelelo ngqo kwi ekukhuleni umbungu kwixesha lokuqala kunye nokusekwa kwe blastocyst. Nto layiva kakuhle, nokuba amadlozi ngezinga eliphezulu eqhekekileyo nga kwakheke iiseli yintsholongwane nemazi, kodwa kamva xa nisaqala yenkqubo yophuhliso ndiseyimbumba ukuze ayeke.

Kubanga zokugula

Ukophulwa ulwazi yemfuza kwisidoda ezinokubangelwa kwizinto ezahlukeneyo ezibangela ukuba zombini ngaphakathi nangaphandle. inzalo Male lunokwenzeka ngenxa ukwaphulwa ezininzi iinkqubo ezahlukeneyo ephilayo, ezifana:

• sex;
• ezidalwe;
• thazeke;
• yegazi;
• omzimba kwaye njalo njalo.

Umsebenzi ophambili we iiseli oyindoda sokuzala makanikelwe izinto yeqanda esempilweni ngaphandle umonakalo. Kuphela kulo mzekelo emva kokukhulelwa wokugqibela ndiseyimbumba iza kuphuhlisa ngokwesiqhelo ngokupheleleyo. Kungenjalo, kusenokubakho ezimbi ezahlukeneyo. Ngenxa yokuba into eyenzekayo DNA zomhlaba?

ezibangela yangaphakathi

Imiba yangaphakathi izizathu ezibini. Eyokuqala kwezi luphuhliso madlozi sinesiphene. Nokuvuthwa kweeseli lwegciwane oyindoda lwenzeka kwi epididymis. Ngelo xesha, ukuba isebenze chromatin, nto leyo ifumaneka esiseleni nucleus. Lunoxanduva ukuba isidoda motility. Kwezinye iimeko, le nkqubo ukuya ephosakeleyo, yaye ngoko ke kweleli iDNA yonakele.

Umba yangaphakathi yesibini yi gametes ukulahlwa ayilunganga. indalo isidoda yenzeka amatyhalarha. Le peculiarity komzimba inkunzi ke ukukwazi ukufumanisa imeko iiseli lwegciwane. Ukuba isidoda kuvandlakanywa lunomahluko ezithile ngokwalo yemfuza okanye umahluko kubume, umzimba lokubhangisa kubo. Kodwa inkqubo ngezinye kucuthwa into engalunganga. Kulo mzekelo, i ejaculate ziya iiseli okunempilo yonakele.

izinto zangaphandle

Ukongeza lwangaphakathi ebangela DNA nokuqhekeka iiseli ibe ngenxa eziliqela zangaphandle. Ezi kungathathwa ubukho izifo ezithile ukuba kwenzeka ngohlobo oyingozi okanye engapheliyo. Ukutshatyalaliswa iiseli lwegciwane ezinokubangelwa ukudumba phecana enzala. Oku kubonakala ngakumbi kwiimeko apho kukho isibetho asiqhenqethanga siphilisiwe ngokupheleleyo.

Ngokufuthi, unobangela kwaye onjalo phakathi kwabantu kwande izifo, njengokuba varicocele. Ngokuqhelekileyo lula ukubona ngezifo of ngemithambo inimba kule amasende. Kodwa ukuxilongwa ngakumbi iya kuseka uviwo efanelekileyo. Kodwa ngaphandle koko, izizathu kungaba:

• lobushushu eliphezulu ixesha ngokwaneleyo elide, kunye akukho zimpawu ezicacileyo kunye neempawu;
• phambi ntshikilelo oxidative;
• X-reyi zokukhanya;
• lokudlula ichemotherapy;
• nemikhuba emibi.

Kwinqaku lesibini, isidoda DNA ukuqhekezwa yenzeka ngenxa yokutshaya.

Okwangoku, zininzi iindlela zokulwa nalo mkhwa yingozi. Kwaye ukuba ufuna ngayo ukukhulisa abantwana, ukuba kushiywa ngokupheleleyo. Kwaye ke msinyane, ngcono!

uxilongo Standard - yobudoda

Kaloku ukuzalwa komntwana esempilweni ngokupheleleyo idinga into elungileyo yemfuza. Kwaye ukuze ukumisela ubume iiseli lwegciwane eyindoda, uhlalutyo oluqhelekileyo ngaphandle ejaculate wenziwe. Isiphumo sale sifundo zibonisa ukuba oonobangela kwephulwa isichumiso. Uhlalutyo amadlozi ikwavumela ukumisela isakhiwo, ingqondo, iqondo ukuhamba kweeseli lwegciwane eyindoda, kodwa kwangaxeshanye kwaye ukhangele ukuze kuthotyelwe norm nokomzimba. Kwakhona ifakiwe kuhlalutyo umsebenzi yokufumanisa i-asidi ulwelo ZakwaLizwi Zehlabathi.

Ngapha koko, le sifundo ukufumanisa inani leukocytes, apho ngokuqhelekileyo kufuneka ibe ngaphezulu kwesigidi milliliter amadlozi nganye. Ipharamitha ebalulekile umbala kunye nevumba. Healthy cerebrospinal ZakwaLizwi unalo emhlophe nombala off-ezimhlophe okanye pink kancinane, kwaye nevumba kufana nezompleyini. Ukuba kukho nayiphi na ukutenxa kufuna uviwo ngokucokisekileyo ngakumbi, nto leyo ethatha isigqibo igqirha ngokwesiseko isiphumo.

Kodwa ke, iingcali zikholelwa ukuba uhlalutyo esezantsi nako ukuqinisekisa ukuba ngaba DNA zomhlaba lowo. iindlela Survey nje musa ukuvumela ukuba enze njalo njengoko la madlozi kakhulu kugqitywa kuphela physical parameters ze kulwelo ZakwaLizwi Zehlabathi. Ngoko ke, lokufunyaniswa ikhonkco iDNA ngale ndlela yokwenza oko akunakwenzeka, kunye neengcali bacebisa ukusetyenziswa kwenye ubuchule eqhelekileyo ebizwa TUNEL.

Kakuhle eli indlela TUNEL

Iingcali ezininzi Siyaleza ukuhlola ukulandelelana DNA ye-nkqubo elinikiweyo. Uphando ukwenzela ukuqinisekisa ukuba isixa (%) of gametes ezonakeleyo. Ngokusekelwe kwiziphumo, uyakwazi ukufumana iindlela eziyimfuneko unyango ukuze kwandiswe amandla abantu ukuba umgquba.

Emva ngokubeka isidoda kulo ukongeza wezenzi ezizodwa, yaye uphando lwenziwa usebenzisa ngemicroscope. Kulo mzekelo, inani madlozi okunempilo yonakele zingabonwa ngokucacileyo. An Umphandi onamava ngokukhawuleza ngokuchanileyo ukuchonga utshintsho DNA. Ukuqhekezwa madlozi kulo mzekelo kwabonakala into yokuba iiseli yintsholongwane umonakalo zahluke kakhulu ngembonakalo yabo.

Isiphumo isifundo ikhutshwa kuphela uchwepheshe abaqeqeshiweyo esandleni kwisigulana ngohlobo imifanekiso kunye nomfanekiso iiseli. I parameter ebalulekileyo uphando yipesenteji iiseli okunempilo ukuze lahlulahlulwe. Ngokwesiqhelo, inani leeseli owenzakeleyo engaphenduli kwi-15%.

Sicatshulwa lolu phando ibandakanya iqela lwemithetho mandatory. Kwiintsuku ezisixhenxe, musa emanzini ashushu uze ukuphelisa ngeenyawo sokuhlambela. Ngeli xesha, kufuneka basenokuziphepha iintlobano zesini kwaye uyeke utshwala. collection isidoda kwenziwa ngomhla inkqubo kwisikhongozeli ekhethekileyo eyenziwe ngeplastiki. Oku kwenziwa ekhaya kwindawo yonyango.

Ndinokwenza uqale nini ukuba ukhathazeke?

Amadoda amaninzi musa kuphela abayazi into DNA ukuqhekezwa izinga zesi salathisi ngayo nayo ayaziwa. Njengoko, ke, emva koko, ngaxa ethile kufuneka ukuba bahlolwe. Ngenxa yesi sizathu, akukho kukhula ubudlolo kwakunye ukuvela zizifo ezahlukahlukeneyo. Kule nkalo, kufuneka nesiphumo kwiimeko apho iqula kufuneka ingqalelo:

• Intsapho ixesha elide awukwazi ukukhawula umntwana.
• Ngaphambili kubekho iinzame eziliqela amadlozi ngesirinji apho.
• Imeko enganelisiyo mbungu.
• Ndandiyithanda kwisiqingatha sesibini kwezisu rhoqo, kodwa ke ngokucacileyo kuyo.
• Madoda ubudala 45 nangaphezulu.
• Ukubakho imithambo varicose ye intambo spermatic.
• iinyanga ezintathu okanye ngaphezulu kokubona amadoda nomkhuhlane.

Ngokubhekisele Kwimeko yokuqala, oku kudla ngokuba ngelo xesha, abafazi ajongwayo kule ndlela apho kwenzeka ukuba basempilweni ngokupheleleyo, kodwa ukukhulelwa lungenzeki. Kulo mzekelo, kufuneka ukuba aqwalaselwe kunye namadoda.

Ukuhlolelwa ukuba iseli lwegciwane ukuqhekeka lityumbe ugqirha lobuqu phantsi kweemeko ezithile kuphela.

Ndisenako uhlolwe phi?

Ngoku Yinto eyaziwayo ukuba lo eqhekekileyo DNA, "apho lokuphumelela" - lo mbuzo olandelayo ezivelayo. Okwangoku, phantse wobunzululwazi ngezixhobo mihla sele ephanda imbewu eyindoda. Ukuba ivavanywe banokuba phantse naziphi na izibonelelo zempilo zikarhulumente ngaphandle kwentlawulo. Nje elinde iziphumo singathatha iintsuku ezininzi. Ukuba qhagamshelana omnye iziphumo lab zabucala ziya kufumaneka phakathi ngenye imini.

Kubalulekile ukukhumbula ukuba yonke uphando yahlukile na isiphumo. Ngoko ke, ngokuba ukuthembeka kubhetele Kwathi ezinye iimvavanyo kumqolo. Ekuphela kwendlela ugqirha bahlanganise amaqhekeza kunye nokumisela ukuxilongwa.

Ukuphucula degree eqhekekileyo

De kwexesha elithile Kuyenzeka ukutshintsha i izinga DNA uqhekeko ngendlela engcono. Kodwa emva kokuba akukho kwakudala, ukuba ufunda ayizange olungqiniweyo. Ukuncipha ukuqhekeka kwenziwa ngokuthi kwaziswe antioxidants zibe umzimba umguli. Kodwa kwezinye iimeko uhlalutyo DNA nokuqhekeka madlozi ayihambelani ukuqinisekisa ukuba iziphumo ezidibanisayo.

Umzekelo, ukuba inguqu ezibangwa kukungakhuseleki elide iiseli obushushu aphezulu okanye izinto eziyityhefu.

impahla eluncedo folate

Emva kokuba abaphandi abahlalutya amandla amadoda amaninzi, beza wenza isigqibo umdla. Okuya uba mkhulu umsantsa ubungakanani folic acid kwi ekutyeni, encinane into kwasekwa iiseli ezingaqhelekanga. Ngoko ke kuyimfuneko ukuba iinyanga 3-4 phambi kokuba isicwangciso ukukhulelwa ukufaka kwi ezityiwa acid, esifunyaniswe ekutyeni ezahlukeneyo. Phakathi imveliso yezityalo zezi:

• imifino;
• cereal, amasiko bean;
• bananas;
• sohlobo;
• iminqathe;
• nuts.

Acid ifumaneka kukutya zezilwanyana:

• kwesibindi kunye nenyama yenkomo, yehagu kunye imvana;
• salmon;
• egg sac.

Kwakhona khona iimveliso zobisi.

Xa unyango ubushushu ezinye ilahleko yemveliso acid ifikelela kwi-90%. Ngoko ke, kangangoko kunokwenzeka kungcono ukutya ekrwada. Quka ezityiwa ezi mveliso, unokuqiniseka ukuba uhlalutyo lwe-DNA ukuqhekeka kuzakubonisa iziphumo ezihle. Oku kuthetha ukuba akukho mfuneko yokuba phele kwimpilo elizayo usana lwakho.
