Isigaba eyinhloko folliculogenesis Ukwakheka kwezitho okuyizona (primary) follicle.

follicle evelele ezakhiwe izigaba ngokulandelana kokuqhubeka:

- ukuqala kumiswa uquqaba encane follicle antral ,

- ukukhula nokuthuthuka of follicle encane

- nokuvuthwa we follicle evelele,

- ukukhiqizwa kwamaqanda.

Singasho ukuthi ovuthiwe follicle evelele - iqanda, okumele sovulirovat. Ngakho, kuyacaca ukuthi nazo zonke lezi zinyathelo follicle ekwakhekeni, ekugcineni ovulate, isb kungenzeka sokukhulelwa.

Ukwakheka follicle encane iqala ezinsukwini zokuqala nomjikelezo wokuya esikhathini. Nokho, ukukhula kwabo iqala kuphela gormonozavisyaschuyu esiteji ukuthi kuza ngokushesha emva kokuphothulwa esigabeni luteal. Ngesikhathi esifanayo kunciphisa inani estradiol futhi progesterone, kodwa inani follicle eqabulayo i-hormone (FSH) kwandisa.

Kufanele kuqashelwe ukuthi follicle evelele kuthintwa izici eziningi ezingase ziholele ekufeni kwakhe. Nokho, umzimba female yakhelwe ukuze zonke izinqubo zawo ahloselwe ekulondolozeni iqanda umquba. Ngakho-ke, follicle evelele "ukuvikela" epidermal ukukhula factor nokuguqula ukukhula factor (TGF).

Ngemuva kwezinsuku 5-7 lapho kuqala ukuya esikhathini okokuqala ekuqaleni ukwakha follicle encane. Zibizwa ngokuthi nangokuthi ephakeme noma antral. Zazo zikhona eziningi ngempela - izingcezu-10. Lesi sigaba sibizwa ngokuthi Ngasekuqaleni folliculogenesis ayanda noma ekuqaleni kumiswa encane follicle antral . I ububanzi lezi zinkampani ezincane ingeqi 5 mm. Basuke etholakala a "bead" azungeze esibelethweni. Okwesikhathi esithile, ingxenye inyuka follicle ngobukhulu begodu kuragela phambili kuba.

Ngenxa yalokho, kwakhiwa i-follicle evelele is ngemva cishe 10 izinsuku nomjikelezo wokuya esikhathini, futhi ngalesi sikhathi Ubukhulu bayo ukufinyelela 15 kwangu. Lamanye ahamba follicle ukuthi zehlulekile azuze isisindo ezidingekayo abaphindela futhi bafe. Ngenxa yalokho, singaphetha ngokuthi lo follicle evelele kungaba angaphezu kwelilodwa. Lapho amaqanda amabili noma ukhulile iziphi ke avundiswa, ukuthuthukisa nokukhulelwa izingane eziningi ngasikhathi. Le nqubo akuyona ovamile, kodwa Ezimweni ezinjalo elotshiwe. Ngokuvamile kuba izimbangela iatrogenic: izidakamizwa esekelwe hormone, nokukhandela imbeleko ngomlomo noma IVF. Kodwa wawususa futhi imbangela bokuphila ukuzalwa kwamawele kuyisenzakalo futhi ezintathu.

Ukuqondisa isikhathi nge-ovulation follicle evelele kumele ukufinyelela ububanzi of mayelana 20 kwangu (mhlawumbe okuningi). Ngesikhathi indawo ye follicle yakha luteum Corpus has kancane ezincane kuneyokuqala.

Uma kokukhulelwa ingekho, bese ngesonto emva kokukhululwa kwe-iqanda kusuka esibelethweni Corpus luteum uqala wehlise ngosayizi - regresses. Ngesikhathi lesizalo endothelial ukwenqaba le luteum Corpus, njengoba umthetho, afe, futhi endaweni yawo kuphela ingxenye echogenicity eziphukile asele.

Ekhuluma folliculogenesis, ayikwazi ukugxila welithi "follicle eziphikelelayo."

Ukuqhubeka ebizwa ngokuthi follicle, oludlula zonke izigaba folliculogenesis, ngaphandle nge-ovulation ngokushesha. Iziphi izizathu kungaholela lesi simanga bengayiqondi ngokugcwele. Nokho, odokotela bavame ukuthatha ukuphikelela njengoba okufana kuyinsakavukela khona, yebo, uma kungenziwanga njalo okuphindaphindiwe.

Ngezinye izikhathi kuyenzeka ukuthi follicle eziphikelelayo iguqulwe ibe nginesimila encane wesibeletho. Iziguli ababengenaso nginesimila, kumelwe uzigcine. Uma le nqubo akakubangeli izikhalazo, ukuphathwa ayidingekile.

Njengomthetho, ophikelelayo follicle uyadabuka ngesikhathi nge-ovulation, kodwa ukhulelwa ngesikhathi lesi simo cishe engenakwenzeka, ngoba endometrium lesizalo kakhulu bavale i yenzeka.
