Kirok be?a navi ye u ji
bestere?aneya

Be?a aliye derveyi hekdankan weki tukil te navkirin. Tukil bi
ruke?e?aneye
dapo?rav e. Di bin cina ruke?e?aneye de cina sipik (bi latini:
tunica albuginea
) cih digire. Cikildanen hekdanke di be?a tukile de, di bin cina sipik de cih digirin. Cikildan ji
xaneya heke
ya negihi?ti u xaneyen derdani (bi inglizi:

) pek te.
[7]
Hekexaneya (xaneya heke) negihi?ti weki oosit (bi latini:
oocyte
) te navkirin.
[8]
Di be?a tukil a her hekdankek de bi hezaran cikildanen hekdanke cih digirin. Li gor rejeya perisine, ne yek le cendan cor cikildanen hekdanke heye. Herwisa li gel cikildanan, pekhateyen weki
tene zer
u tene spi ji di hekdankan de cih digirin.

Di la?e meya bi temene pegihi?ti de her meh hekdanek calak dibe.
Cikildanen heri negihi?ti yen hekdanke ne. Ango cikildanen pe?eng in. Ji hekexane ya negihi?ti u ji rezek cikildanexane (xaneyen cikildane) yen li derdora hekexaneye pek te.
[9]
Di qonaxa cikildana pe?in de hekexane ya negihi?ti, ango oosit, weki oosita yekem (bi inglizi: primary oocyte) te navkirin. Perisina Oositan di qonaxa profaz a
miyoza
yekem de hatiye rawestandin. Dema ji dayikbune de, di hekdanken dergu?a me de bi qasi 1.5 milyon cikildanen pe?in heye.
[4]
Di temene pegihi?tine de ango di temene 12-14 sali de hejmara cikildanen pe?in dadikeve 400 hezari.

Di destpeka temene pegihi?tine ?unve (12-14 sali) bi bandora
hormona handere cikildane
(FSH), cikildana pe?in diperise u cikildana yekem peyda dibe.
[6]
Di her cikildanek yekem de oosita yekem, bi rezek an ji pirtir rezen cikildanexane yen ?e?ruyi dapo?rav e. Di cikildana yekem de cikildanexane edi weki xaneyen granuloza (bi inglizi:
granulosa cells
) ten navkirin. Hormona estrocen ji xaneyen granuloza te derdan. Cikildanen yekem hem diperisin hem ji hormona estrocen der didin. Estrocen u procesteron guherina navpo?e malzaroke han dikin.
Cikildana duyem (bi inglizi:
secondary follicle
)

Ji ge?buna cikildana yekem, cikildana duyem cedibe. Cikildana duyem ji oosita yekem, gellek cinen xaneyen granuloza u antrume pek te. Di ve qonaxe de oosita yekem ji aliye du pekhateyen parezer ve hatiye dorpeckirin. Ji van pekhateyan, a yekem weki navceya zelal (bi latini:
zona pellucida
) te navkirin u li ser ooside de cih digire, pekhateya din ji weki taca tiroji (bi latini:
corona radiata
) te navkirin.
[4]
Taca tiroji li ser navceya zelal cih digire. Be?a di navbera taca tiroji u xaneyen granuloza bi ?ileyek tiji ye, nave ve be?e antrum e.
Cikildana gihi?ti (bi inglizi:
Graafian follicle
)

Cikildana gihi?ti ji oosita duyem a bi navceya zelal u taca tiroji dorpeci, ji firerezen xaneyen granuloza u ji antrumek fireh a bi ?ile tiji pek te. Oosita duyem miyoza yekem temem kiriye, ango edi haploidi ye u di qonaxa metefaza miyoza duyem de rawesti ye. Di qonaxa cikildana pegihi?ti de cikildan u antrum gellek mezin xuya dibin.
Bi bandora
hormona handere tene zer
(LH), cikildana pegihi?ti diqeli?e u oosita duyem ber bi coga heke te paldan. Be?a mayi ya cikildane, di nav hekdanke de diguhere, qabareya xaneyen cikildane (xaneyen granuloza) zede dibe u xane bi cewri tiji dibin.
Cewri
renge zer dide xaneyen cikildane. Ev be?a zer a cikildana beoosit edi weki tene zer (bi latini:
corpus luteum
) te navkirin. Tene zer di nav hekdanke de hormonen procesteron u estrocen berhem dike u der dide.
[11]
Evan hormonan navpo?e (ruye navi) malzaroke sturtir dikin bo ceqina embriyoye.
Temene tene zer bi qasi 12-14 roj e.
[12]
Pa?e tene zer ji aliye xaneyen hellu?ener ve ten hilwe?andin, pekhateyek spi ya ji bestere?ane peyda dibe. Nave ve pekhateye tene spi ye (bi latini:
corpus albicans
). Piraniya tene sipi te mijandin, hinek ji tene spi ji di nav hekdanke de mina lekeyen sipi dimine.
- Cikildanen hekdanke xurek dabin dikin bo hekexane ya negihi?ti.
- Dema
hekdanane
rek dixe.
- Malzaroke, cogen heke u zeye amade dike bo
pitina
heke ji aliye
sperm
ve.
- Navpo?e malzaroke amade dike ji bo ceqina heka pitandi.
- Di destpeka ducaniye de bo korpeleye hormonen estrocen u procesteron berhem dike, pa?e heman hormon ji aliye
hevalbicuke
(plasenta) ve te berhemkirin u derdan.
