Isigaba of umjikelezo wokuya esikhathini uwubufakazi

Ngaphambi sikhuluma izigaba nomjikelezo wokuya esikhathini, kubalulekile ukusho ukuthi limelela. umjikelezo wokuya esikhathini uwubufakazi - kuyinto izinguquko nyangazonke bokuphila kuleli ezikhiqiza amaqanda nowesifazane ubulili izitho, okwenzeka ukuze ulungiselele umzimba ngoba ukukhulelwa kungenzeka. Lokhu kuhilela hhayi kuphela Izitho zokuzala, indima ebalulekile ubuchopho futhi uhlelo hormone.

Lonke umjikelezo zingahlukaniswa zibe izingxenye ezine. Ezinye izazi zithi mayelana incorrectness ka ukwahlukana enjalo, futhi ikunika ezimbili kuphela izigaba of umjikelezo wokuya esikhathini uwubufakazi: follicular futhi luteal. Eqinisweni, kokubili ngeengaba basuke kucishe. ibonisa Iningi ngokunembile izinqubo belungiselela ukukhulelwa kungenzeka ngezigaba okokuqala ehlukanisa izigaba ezine nomjikelezo wokuya esikhathini. On kubo kuzoxoxwa ngezansi.

Eyokuqala izigaba ezimbili zibonisa belungiselela ukwakheka amaqanda, ezimbili zokugcina - ukwakheka ukulungiselela Iqanda ukuze ukukhulelwa nokuzalwa / ukufa neqanda. Ake sicabangele ngayinye yalezi zinkulumo ngokwehlukile.

Isigaba sokuqala umjikelezo uqala ngosuku lokuqala kakhulu lapho eseqala ukuya esikhathini. Ngalesi sikhathi, senqaba the endometrium, futhi umzimba ubhekisa ukunakekela yayo ekwakhekeni iqanda elisha. Ngesikhathi le nqubo ithatha kusukela ezinsukwini ezintathu kuya kweziyisithupha, kodwa ngaphambi kokuphela kwenyanga kufika elilandelayo isigaba, follicular.

Isikhathi lomjikelezo wesibili ihlala ngemva cishe amasonto amabili yaphela ngenyanga. Umjikelezo kule isikhawu igxile ekuthuthukiseni follicle ngaphansi isenzo le-hormone, elinye lawo (okuyizona) kamuva ukuvuthwa amaqanda. Ngesikhathi esifanayo, i-estrogen ilungisa lesizalo ulwelwesi kanye isikhwehlela wesibeletho okwenza ungenakonakala isidoda.

Isikhathi kwesikhathi elilandelayo, isigaba nge-ovulation, cishe izinsuku ezintathu. Ngalesi sikhathi snizhet ezingeni i-hormone follicle-inkanuko, okuyinto akhale luteinizing okwenza yamukele isidoda isikhwehlela wesibeletho. Ngaphezu kwalokho, le hormone kuthinta kwaqedwa we oocyte nokuvuthwa, sebenzi whereupon it ukhululeka follicle (nge-ovulation). esibelethweni avuthwa uthuthela tube fallopian, lapho cishe izinsuku ezimbili ukulinda kuze kokukhulelwa.

Esikhundleni sesigaba wesine umjikelezo wokuya esikhathini uwubufakazi - luteal. Ngemva kokudedelwa follicle eqandeni, ithunyelwa kokukhulelwa, kanti follicle iqala ukukhiqizwa progesterone. Indima progesterone siwukulungisa le endometrium lesizalo ukuncela iqanda eselivundisiwe. Ngesikhathi esifanayo kokuba uyeke ukukhiqizwa of luteinizing hormone, okuyinto ephinda kwenza isibopho wesibeletho ungenakonakala isidoda. Cycle isigaba sesine kungathatha izinsuku ezingu-16. Umzimba ukumuncwa esiteji wesizalo iqanda eselivundisiwe, okuyinto eyenzeka izinsuku 6-12 emva kokukhulelwa ukulinda.

Uma indlovukazi wathatha iqanda ngokushesha uqala ukukhiqiza ihomoni ekhethekile, engaphansi kwethonya luteum Corpus izosebenza phakathi nokukhulelwa. Kuyinto ukuba le hormone has a sokukhulelwa ukuhlolwa ebucayi.

Uma ekukhulelweni lube khona, iqanda kanye ufa umzimba ophuzi, iyeke ukukhiqiza progesterone, ngoba nakanjani kulandela ukubhujiswa futhi wenqaba endometrium. Ngamanye amazwi, uqale ngenyanga, futhi zonke izigaba umjikelezo wokuya esikhathini uwubufakazi ezilandelana futhi.

Okuphawulekayo iqiniso elandelayo. Zonke izigaba ezine umjikelezo wokuya esikhathini uwubufakazi achazwayo ngaphansi kwethonya hormone, ezithinta hhayi kuphela izitho zomzimba, kodwa futhi ku isimo esingokomzwelo abesifazane. AmaShayina asendulo ayekholelwa ukuthi ulwazi izici esigabeni ngasinye umjikelezo ibuthinta ngokuqondile phezu inhlalakahle abesifazane. Ngakho, ekuqongeleleni amandla senzeka phambi nge-ovulation, Ngakho-ke, uma owesifazane ukugcina amandla engxenyeni yokuqala lomjikelezo, ivumela yakhe ukuba siphile ngokuvumelana ukuzithuthukisa emhlabeni.
