Okumangalisayo, kodwa inyaniso: kungekudala okanye kamva malunga nomntu ngamnye ucinga ngokuqhubeka kwentsapho. Kwaye abanye abantu baphupha abantwana ngaphezu kwamakhosikazi abo. Kodwa xa kuziwa ekulungiseleleni ukukhulelwa, ootata baya kuba bakholelwa ukuba abanakwenza nto ngeli xesha. Kwaye bayaphutha. Amadoda kunye nabasetyhini banegalelo kwimfuza yomntwana kwaye banembopheleleko yempilo yengane okanye intombi yabo.
Ukongeza kwimfuza, kukho enye into ebalulekileyo yokulungiselela ukuzaliswa kwentsapho. Ukususela kumntu ngeendlela ezininzi ukukhulelwa komntu kuxhomekeke. Njengoko iimanani zibonisa, malunga nesiqingatha seemeko zokukhulelwa azikho ngenxa yokuzala okuphantsi komntu. Ngaloo ndlela, isibonakaliso esiphezulu sokuzala sinomgangatho wesidoda, esinqunywe ngamapalitha njengenani le-spermatozoa, ukuhamba kwawo, isakhiwo (morphology) nokusebenza.
Ukuqonda ukuba kutheni indima ebalulekileyo idlalwe yiyo mpawu, makhe sikhumbule ukuba kwenzeka njani ukukhulelwa.
I-Spermatozoa ingena kwisigxina se-uterine 30-60 imizuzu emva kokunyuka, kwaye emva kweeyure eziyi-1.5-2 zifaka i-ampulla ye-tube ye-uterine. Iqanda lifunyenwe apha ngokuqhelekileyo kwiiyure ezingama-24 emva kokuvuthwa. Emva koko iqanda litshiza okanye life. Xa i-spermatozoa "ifumana" iqanda, idibanisa igobolondo layo, kodwa ingene kwiqanda leqanda, njengomthetho, kuphela enye i-spermatozoon inokwenzeka. Kulo lonke, igobolondo ayinakunceda. Emva kokuba i-spermatozoon ingena kwiqanda, i-nucleus yayo idibanisa kunye nenqama yeqanda, kwaye i-chromosomes yisehlo yenza isethi enye kunye nama-chromosomes kamama. Malunga nomhla emva kwalokhu, isalathisi esiphumela siqala ukwahlula - isigaba sokuqala sokuqala komntwana.
Ngokwemfundiso, yonke into ilula. Kodwa inyaniso iyinkimbinkimbi kakhulu. I-spermatozoon inamanani amancinci kakhulu (ngamaxesha amancinci angama-8 kune-pixel). Ukuze "ufike" kwiqanda, isidoda kufuneka sikwazi ukunqoba umgama omfutshane, ongaphezu kwama-3636 amaxesha. Ukuba indoda yayifanele ihambe kuloo ndlela, kwakufuneka ihambe ukusuka eMoscow iya eVoronezh. Ngaba ucinga ukuba abaninzi banokujamelana nalo msebenzi? Yingakho kubaluleke kakhulu ukuba i-spermatozoa ifumaneke kwaye ibe nesakhiwo esifanelekileyo. Kwaye uninzi lwesilisa kwi-semen, ephakamileyo ithuba lokuba okungenani omnye wabo angafikelela kwiinjongo.
Makhe sithethe ngakumbi malunga nesikhombisi ngasinye.
Izibonakaliso zokuzala komntu
Njengoko sele sifumene, ukuze sidibane ne-ovum, i-spermatozoa kufuneka ihambe ngokukhawuleza kwaye ibe linye icala. I-Spermatozoons ithathwa njengengasebenzi xa iintambo zabo zineesetyhula okanye zinyukayo endaweni enye (manezhnye okanye i-pendulum) - kulo mzekelo i-spermatozoon ayikwazi ukufikelela kwi-ovum. Imbewu eqhelekileyo iqwalaselwa, apho ubuncinane ubuncinane be-spermatozoa engama-40%.
Isakhiwo esilungileyo sinqumle nje ukukwazi ukuhamba, kodwa kunye nokukwazi ukungenisa iqanda. I-spermatozoon ithathwa njengento echanekileyo yokuziphatha xa intloko yayo inomgca ogqithiseleyo kunye ne-acrosome ecacileyo. I-acrosome yimbumba ye-membrane ne-enzymes echitha iigobolondo zeqanda ukuze ingene kwi-spermatozoon kuyo. I-acrosome imele ibambe i-40-70% yentloko. I-spermatozoon akufanele ibe neempembelelo zentloko, intamo, inxalenye ephakathi kunye nomsila.
Uxinzelelo lwe-spermatozoa kwi-ejaculate lubaluleke kakhulu. Iimeko apho iigermatozoa ezinempilo ezingama-39 okanye ngaphezulu ziwela kwi-milliliter enye yesidoda zibhekwa njengezityalo zokuzala. Ukuze utyalo luphumelele, ubuncinane ubuninzi be-spermatozoa ezili-10 kufuneka bangene kwisibeletho.
Indlela yokuvavanya ukuzala komntu?
Indlela eqinisekileyo yokwenza uhlalutyo lwe-ejaculate, i-spermogram. Ukucacisa i-spermogrammy kuya kukuvumela ukuba uqikelele umgangatho wembewu, ukubonakalisa iingxaki ezinokuphazamisa ukukhulelwa, nokuzinqumla.
Ngokuhambelana nemigangatho ye-WHO, i- spermogram enhle kufuneka ihlangabezane nale migqaliselo elandelayo:
- Umqulu we-ejaculate: 1.5 ml okanye ngaphezulu.
- Inani elipheleleyo le-spermatozoa kwi-ejaculate: izigidi ezingama-39 okanye ngaphezulu.
- Ukuxinwa kwe-spermatozoa kwi-1 ml: izigidi ezili-15 okanye ngaphezulu.
- Ukuhamba ngokupheleleyo kwe-spermatozoa: 40% okanye ngaphezulu.
- I-Sperm eneentshukumo eziqhubekayo: 32% okanye ngaphezulu.
- Ukukhubazeka kwe-spermatozoa: i-58% okanye ngaphezulu.
- I-Morphology: iifom zesiqhelo 4% okanye ngaphezulu.
Indlela yokuthatha i-spermogram?
Ngaphambi kokubeka imbono ekuhlaleni, kuyimfuneko ukuba uyeke kwisenzo sesondo ubuncinane iintsuku eziyi-3-4, kodwa kungekhona ngaphezu kweveki. Awukwazi ukusela utywala (kuquka ubhiya), amayeza, tyelela i-sauna, uthathe ibhafu elitshisayo. Iqondo lokushisa eliphezulu kangangokuba i-sperm ayifi, i-20-37 ° C, ukupholisa isidoda esingaphantsi kwe-20 ° C ikhokelela ekuphambukeni kweendlululo. Ngoko ke, kungcono ukuthatha uhlalutyo kwigumbi elinye apho i-laboratory ikhona khona. Kubalulekile ukuba zonke izilwanyana ezifakwe kwii-glassware zelabhoratri zenzeke. Ukulahlekelwa ubuncinane kwisabelo esinye kunokuphazamisa umphumo wesifundo.
Ukuba inkcazo ye-spermogram iphezulu, uhlalutyo olulodwa lunokwanela. Kodwa ukuba ufumanisa i-pathologies kwi-ejaculate, uza kufuna uhlalutyo lwezinto ezimbini okanye ezintathu kunye neentsuku ezi-7.
Ngaba kufuneka ndiyithabathe?Akubona bonke abantu abavuma ukuhamba ukuhanjiswa kwe-spermogram kwisigaba sokucwangcisa ukukhulelwa. Ewe, le mpazamo iyaqondakala kwaye inokuthi ilandelwe inombolo yezizathu ezifanelekileyo. Nangona kunjalo, nawuphi na umzekelo, indoda kufuneka icinge ngendlela yokuphucula umgangatho wesilisa kunye nokwandisa ukuhamba kwe-spermatozoa. Inyaniso kukuba ngaphezu kwehafu yesigqithi esedlulileyo, umgangatho wesilisa kumadoda uye wancipha kakhulu. Oku kubangelwa ukuba i-concentration, morphology kwaye, ngokubaluleke kakhulu, i-motility ye-spermatozoa inokukhathazeka kakhulu kwimpembelelo yezinto zangaphandle: ukungonakaliswa kweemeko zendalo, ukusetyenziswa kotywala kunye nemichiza, ukutshaya, ukungondleki, njl.
Ukwandisa i-motility ye-spermatozoa kunye nomgangatho wobisi kuza kunceda amalungiselelo athile e-vitamin. Kubalulekile ukuqonda ukuba ukususela kokuvuthwa kwe-spermatozoa kuthatha iintsuku ezingama-72, loo ndoda kufuneka inikwe ubuncinane iinyanga ezintathu ukucwangcisa ukukhulelwa. Iithamini zamadoda ngeli xesha kufuneka zithathwe imihla ngemihla. "Iivithamini zamadoda" kufuneka ziqukethe i-zinc, i-vitamin E kunye ne-L-carnitine kwimilinganiselo ephezulu. Zonke ezi zixhobo ziyinxalenye yesilwanyana "Spematon". "I-Spematon" ivuselela i-spermatogenesis kwaye iphucula umgangatho wesilisa ngenxa yokuba:
- I-carnitine ikhulisa inani le-spermatozoa, liphucula ukuhamba kwabo, luza kunceda ukunciphisa inani leempawu zesimo sengqondo esingaqhelekanga.
- I-Zinc ibalulekile ekuqaliseni i-hormone testosterone kunye ne-follicle-stimulating hormone (FSH), eziyimfuneko yokuveliswa kwesilisa.
- I-Vitamin E ikwandisa ukuhamba nokugxininiswa kwe-spermatozoa, yandisa ukwenzeka kwazo.
Yaye ke, kufuneka kukhunjulwe ukuba ukucwangciswa kokuzala akubandakanyi nje iivithamini zamadoda, kodwa kunye nokuphila ngendlela enempilo, ubuncinane ukulahla okwethutyana kunye nokutshaya, ukutya okunomsoco kunye nesimo esihle sengqondo. Ewe, ukuxinezeleka, kuninzi, kwandisa imeko yomzimba wesilisa kwaye kuthintela umgangatho wesilisa.
Iinyanga ezintathu zokunyamekela umzimba wakho kunye nokugcinwa kwemithetho elula yintoni umntu onokuyenza kwimpilo yengane engakazalwa ngaphambi kokuba azalwe.
