Njani ukubunjwa kweeseli zesini zesini?
Ngaphambi kokuba ndixelele ngobungakanani beeseli ze-spermatogenesis kwisiqhelo okanye kwisantya singabakho kwi-spermogram, makhe siqwalasele ngokufutshane inkqubo yokukhula kwe-spermatozoon.
Ngaloo ndlela, ukwakheka kweesini zesini kwindoda kuqala malunga ne-12 iminyaka kwaye idlulela kude kube ngumdala, kubomi bomntu. Ngelo xesha, kuqhelekile ukuba ucinge ukuba ubude bomjikelezo omnye we-spermatogenesis malunga neentsuku ezingama-75.
Ukubunjwa kweeseli zesini zesondo kuqala ngokuthe ngqo ngaphakathi kwimizimba ye-seminiferous tubules. Nganye yee-tubules zabo zahlula i-septum ekhethekileyo kwiinqunithi ezimbini. Kwesinye seziganeko eziphambili ze-spermatogenesis zikhona, kwaye kwisibini - i-spermatogonia, eyabangela ukuba i-spermatozoa ivele. Ngokuqhelekileyo, itekisi enye iqulethe ngaphezu kweebhiliyoni ezifana neeseli.
Ziziphi iiseli ezincinane kwaye zifanele ziquke kangakanani kwi-spermogram?
Njengomthetho, ubukho benani elikhulu lamaseli e-spermatogenesis likhokelela ekuphuhlisweni kweengxaki kubantu. Yingakho esi sibonakaliso sisinye seziphambili ekuhloliseni iziphumo zolu pho nonongo.
Iiseli ezingapheliyo ze-spermatogenesis nazo zibizwa ngokuba yi-spermatogenic. Ezi ziquka:
- iisensi ze- spermatogonia- stem, eziyisiseko sokwakhiwa kwe-spermatocytes;
- i-spermatocytes 1 (uhlale kwi-mitosis ngenxa yesahlulo seeseli esingaphelelanga) kunye nemiyalelo emi-2 (faka 1 i-prophase meiosis, gcwalisa isahluko sokuqala, ubenze njengesiphumo se-spermatocytes nganye);
- i-spermatids ( inekhethi ye- haploid yama-chromosomes kwaye emva kokuba utshintsho lwezakhiwo luguqulwa zibe yi-spermatozoa).
Kubalulekile ukuba uqaphele ukuba iiseli ezilodwa ze-spermatogenesis zikho naziphi na izidalwa ze-spermogram. Ngoko, ngokusemgangathweni ukugxininisa akufanele kudlule ngaphezu kwezigidi eziyi-5 / ml mlume. Nangona kunjalo, ngamanye amaxesha, phambi kophulo-mthetho, esi sibonakaliso sidlulileyo ngumlinganiselo we-10. Uphononongo olutshanje lubonise ukuba le ncwadana ayinayo ixabiso elikhulu lokuxilonga.
Okubaluleke ngakumbi ekunqumeni imbangela yesifo ngumxholo weeseli kwi-cell cell, njenge-leukocytes, okanye kunoko, ifom yabo, njenge-neutrophils. Inani elipheleleyo lazo alimele lidlulele kwi-1 million / ml. Ngaphandle koko, kukho ukuphulwa kwephulo elinjalo njenge- leukospermia, echaphazela kakubi ukukwazi ukuhluma iiseli zentsholongwane.
Kuthekani ukuba i-spermiogram ibonise inani elinyukayo leeseli ze-spermatogenesis?
Njengoko sele kukhankanywe ngasentla, kwintsholongwane evamile ye-spermatogenesis ayikwazi ukuba engekho kwisampuli ye-ejaculate. Nangona kunjalo, ukuba inani labo lilonke lidlula izigidi ezi-5 / ml, ngoko kulo mzekelo bathetha nge-pathology.
Olu hlobo lokuphulaphula ukungaphumeleli kwenkqubo yokwenza i-spermatozoa.
Kwiimeko ezinjalo, umntu unyangwa unyango, olujoliswe ekumiseleni i-spermatogenesis, eyokuqala kwayo yonke into eyenziwa ngokuqeshwa kwamachiza e-hormone.
Ngaloo ndlela, kunokuthiwa ukuba ubukho kwi-spermogram yeeseli ezitshatyalaliswayo ze-spermatogenesis ayikho ukuphulaphula ukuba ingcamango yabo ayidluli kwisiqhelo esisisiseko.
