Kweli nqaku siza kuphendula phi ukuchumisa kwenzeka, kunye neminye imiba efana nini lelona xesha lilungileyo, inkqubo, yintoni na iindlela oko kufuneka kunikwe, i ixesha Ihlala ithatha ixesha elingakanani emva kokwabelana ngesondo, okanye nokuba yintoni na incedisi yokuchumisa.
Sinethemba lokuphendula imibuzo yakho ngaphandle kobugcisa kakhulu, kodwa kufuneka sisebenzise amagama ezonyango okanye ezenzululwazi.
Inkcazo yokuchumisa
Ukuchumisa kuchazwa njengenkqubo ekwenziwa ngayo iinyamakazi ezimbini, enye inkunzi nemazi, ziyahlangana. Olu manyano lwenza ukuba kwenzeke ubomi obutsha. Le yinkqubo eyinkimbinkimbi efuna uluhlu lweemeko ezifanelekileyo. Le nkqubo ayenzeki kuphela kwiintlobo zabantu, kodwa yabelwana ngezilwanyana, izilwanyana ezincelisayo okanye cha.
Kwimeko yabantu, inkqubo yokuchumisa iyenzeka kwi ngaphakathi emzimbeni womfazi, ngenxa yoko kuyimfuneko ukuba ibhinqa libe kwisigaba esithile somjikelezo wakhe wokuya esikhathini. Kwaye ngexesha lokwabelana ngesondo, i-ejaculation iyenzeka ngaphakathi kwi-vagina.
Inqanaba elikhethekileyo ekufuneka umfazi abe kulo ukuze aqhame kunini Iqanda elikhulileyo lishiya i-ovary kwaye likwi-fallopian tube.. Kumjikelo oqhelekileyo oku kwenzeka malunga nosuku lwe-14. Kuzo zonke izigidi zamadlozi aphumayo, malunga nama-200 afikelela kwityhubhu ye-fallopian kwaye inye kuphela eya kulawula ukuwela inwebu engaphandle yeqanda kwaye idibanise nayo.
Isidoda siphila malunga neentsuku ezintathu kule ndawo. Yiyo loo nto kuthiwa le fusion inokwenzeka phakathi kwe-19 kunye ne-72 iiyure emva kokwabelana ngesondo. Kodwa amaxesha anokwahluka kakhulu phakathi kwezinye iimeko kunye nezinye kangangokuba akunakwenzeka ukunika ixesha elithile.
Injani inkqubo?
Inkqubo yokuchumisa inokohlulwa ibe ngamanqanaba amane:
- Ukungena kwe isithsaba esikhazimlayo. Idlozi kufuneka lingene kumaleko weeseli ezijikeleze iqanda. Le yi-corona radiata.
- Ukungena kwe zona pellucida. Kweli nqanaba intloko yesidoda iseka unxibelelwano ne-ZP3 receptor kwi-zona peludida yeqanda. Olu manyano lukhupha ii-enzymes ezivumela ukuba idlozi lidlule.
- Ukudityaniswa kweMembrane. Isidoda sidibana nenwebu yeplasma yeqanda. Ngeli nqanaba, iinkqubo ezi-3 zenzeka kwi-gamete yowesifazane: ukubunjwa kwekhoni yokuchumisa, i-depolarization ye-membrane yayo kunye nokukhululwa kwe-cortical granules.
- Ukudityaniswa kwenucleus kunye nokwakheka kwezygote. Apha idlozi lihambela phambili de intloko yalo ibe kufuphi nepronucleus yebhinqa yaye, xa sele isondelelene, kwenzeka ukudibana. Iinwebu zazo zombini ziyanyamalala, ngoko ke iichromosome zazo zinokudibana kunye kwaye kukho iseli entsha eneseti yokuqala yechromosome evela kubazali bobabini.
I-zygote, ekwityhubhu yesibeleko, uya kuqhubeka iintsuku ezintathu okanye ezine ukutyhalwa yimithambo ye-muscular of the tube de ifike kumgodi wesibeleko. Kule mihla ukwahlukana kweeseli sele kuqalile kwaye i-embryo encinci iya kubambelela kwi-endometrium. Apha iya kuphuhlisa kwaye ikhule kude kube ngumzuzu wokuhanjiswa.
Ukuncediswa kokuchumisa
Njengoko ubona, ukuchumisa kwendalo akukho lula njengoko sicinga. Uthotho lweemeko kufuneka zenzeke kwaye akusoloko kulula. Ngamanye amaxesha ukukhulelwa kunokuba nzima. Ngoko ke, inzululwazi isinika ithuba lokunceda ekuveliseni. Olu luluhlu lweendlela zonyango kunye nonyango olujoliswe ekufezekiseni ukukhulelwa xa ukuchumisa kwendalo kungenakwenzeka.
Xa sithetha malunga nokuchumisa okuncediswayo, asithethi kuphela ngeengxaki zokuzala kwezonyango, kodwa iyanda indlela yokuba abafazi abafuna ukuba ngoomama, kwaye bengenalo iqabane, okanye iqabane lesini esifanayo, babhenela kubo.
Kukho unyango oluncedisiweyo lokuchumisa, inokuthi ifakwe kwi-artificial insemination (AI), ukuchumisa in vitro (IVF), umnikelo weqanda, ukudluliselwa kwe-embryo okanye ukwamkelwa kombungu. Ngamnye kubo unesicelo sakhe kunye nezinto ezikhethekileyo.
