Umjikelo wokuya exesheni okanye umjikelo wesini sowasetyhini yinkqubo apho umzimba womfazi, kule meko isibeleko sakhe, ukwinkqubo yehomoni elungiselela ukukhulelwa okunokwenzeka. Ngexesha lomjikelo umfazi uya kuthatha inkqubo yehomoni emzimbeni wakhe ukuya ukuvelisa iqanda elinokwenzeka ukuba ayifakwanga isichumisi, iya kugxothwa ibangele ukuba kuthiwe sexesheni okanye ukopha.
Umjikelo wokuya exesheni wenzeka rhoqo ngenyanga kubomi bomfazi xa sele ecolile. Ibandakanya iintsuku ezingama-28, kodwa kukho imijikelo enokuhlala malunga neentsuku ezingama-21 ukuya kuma-35. Fumanisa ukuba loluphi na usuku lokuchuma komfazi kwaye unantoni yokuya exesheni.
Xa umfazi ethathwa njengomntu ochumileyo?
Ixesha lokuzala okanye lokuchuma lomfazi Iqala kwiminyaka yokufikisa, malunga neminyaka eli-12 ubudala, kwaye iqala ukwehla kwiminyaka engama-30 ubudala. Ukususela kuloo minyaka ukuya phambili, amathuba okuba azame ukukhulelwa aya kuba ngama-20%, kwaye xa efikelela kwiminyaka engama-40 ubudala, amathuba akhe okuhla aye kwi-5%. Umfazi awusavundisisi okanye usiya exesheni xa usiya exesheni, esihlala sijikeleze iminyaka engama-51 ubudala.
Izigaba zomjikelo wokuya esikhathini
Ixesha okanye umjikelo wokuya esikhathini unokuhlala phakathi kweentsuku ezingama-24 nama-38 kowasetyhini Kwaye yonke into iya kuxhomekeka kubudala bomfazi. Ayifani xa ufikisa njengokuba ukwisigaba sokuya exesheni.
Inqanaba lokuqala lomjikelo: ukuya exesheni.
Ngeli xesha kuxa ukopha kwenzeka oko kubandakanya ukukhutshwa ngobufazi kwilungu lesibeleko okanye i-endometrium yesibini, ukusukela oko akubangakho kufakelwa umbungu okanye ukungabikho kokukhulelwa.
Ngale nto yokopha, umaleko owawugcina iqanda elalingafakwanga sidlozi uyachithwa. Ihlala ihlala kwiintsuku ezi-2 ukuya kwezi-7 kwaye ungabona ukuba amanqanaba ehomoni ye-estrogen kunye neprogesterone asezantsi.
Inqanaba lesi-2: inqanaba lokulandelwa kunye / okanye ukwanda
Kweli nqanaba kwenzeka emva kokuya exesheni okanye ngamanye amagama ngaphambi kokukhutshwa kweqanda. Ihlala malunga neentsuku ezili-10 ukuya kwezi-12 kweli nqanaba kuxa i-pituitary gland yengqondo isayinisa ama-ovari ukuba akhuphe i-estrogen kunye neprogesterone.
Ezi hormone ziya kuba noxanduva lokwenza phakathi kwe-10 kunye ne-20 follicles (amaqanda angavuthiyo) ukuze aqale ukubumba ngaphakathi kwesibeleko. Inye kuphela kubo eya kuba nkulu kunezinye kwaye ifikelele kwinqanaba lokuvuthwa eya kuba ngoyena uya kugubungela wonke umphezulu we-ovary. Zonke ezinye ezenziweyo ziyaqhekeka kwaye zifunxwe ngumzimba ngokwawo.
Inqanaba lesithathu: isigaba se-ovulative
Eli xesha livela phakathi kosuku lwe-14 okanye lwe-15 (ngaphambi komthetho omtsha). Xa ii-estrogens ziphezulu ngokwaneleyo, iqanda sele ligqibile ukukhula. Nantsi indawo yebhinqa ithumela umqondiso wokukhutshwa kweqanda elikhulileyo kwaye liyakuhamba ngapha Ityhubhu ye-fallopian.
Isigaba se-4: isigaba se-luteal kunye / okanye ukugxothwa
Amanqanaba eHormone aqala ukulungiselela ulungelelwaniso lwesibeleko ukuqala ukukhulelwa okunokubakho kwiintsuku ezintathu zokuba i-ovulation ingahlala. Ukuba iqanda alichunyiswanga liyakuguga kwaye alinakuphinda lichume.
Kweli nqanaba kuxa owasetyhini enokufumana utshintsho emzimbeni nasemphefumlweni, qaphela ukuba amabele akho anovakalelo ngakumbi kwaye adumbile, ukugcinwa ngakumbi kolwelo, uziva udiniwe nangakumbi lutshintsho kumsi noxinzelelo.
Ukuba ukuchumisa okunjalo akwenzekanga, i-corpus luteum okanye iqanda liya kubola, linciphise amanqanaba eprogesterone.. I-endometrium iqala ukwehla ngobukhulu kwaye njengoko ingasayi kusetyenziswa kumfazi okhulelweyo, umzimba uya kuyikhupha. Kulapho umjikelo wokuya exesheni uqala kwakhona, kunye nokugxothwa kwilungu lobufazi eline-uterine lining ehamba negazi.
