Amaseli we-spermatogenesis

Uma unquma izimbangela zokungabi nabantwana emshadweni oshadile, bobabili abalingani bahlolwa. Okuyinhloko kwezivivinyo zamadoda kulesi simo yi-spermogram. Lolu hlobo locwaningo luhloswe ekusunguleni isampula yama-ejaculate amangqamuzana e-sex immature, okuyinto ezimweni eziningi ezingavamile kwisakhiwo. Ukuqaphela ikakhulukazi kukhokhwa amaseli we-spermatogenesis, kamuva aphenduke abe yi-spermatozoa.

Ukubunjwa kwamangqamuzana omzimba wesilisa kunjani?

Ngaphambi kokutshela ukuthi amangaki amangqamuzana e-spermatogenesis ejwayelekile noma esingaba khona angaba khona ku-spermogramme, ake sicabangele ngenqubo yokukhula kwe-spermatozoon.

Ngakho-ke, ukwakheka kwamaseli wesilisa wesilisa kubafana kuqala eminyakeni engaba ngu-12 futhi kuqhubeka kuze kube sesikhulile, kuyo yonke impilo yomuntu. Ngesikhathi esifanayo, kuvamile ukucabanga ukuthi ubude bomjikelezo owodwa we-spermatogenesis buyizinsuku ezingaba ngu-75.

Ukwakhiwa kwamangqamuzana wesilisa ocansini kuqala ngokuqondile ngaphakathi kwe-tuboluted seminiferous yamathambo. Ngamanye amashubhu abo ahlukaniswe i-septum ekhethekile ibe ngamashumi amabili. Kwesinye sezici eziphakathi kwe-spermatogenesis zitholakala, futhi okwesibili - i-spermatogonia, okwenza kube khona i-spermatozoa. Ngokuvamile, isilwane esisodwa sinamangqamuzana angaphezu kwezigidi eziyizinkulungwane.

Yimaphi amangqamuzana awakhulile nokuthi kufanele ayenze kangakanani ku-spermogram?

Njengomthetho, ukuba khona kwenani elikhulu lamaseli we-spermatogenesis kuholela ekuthuthukiseni ukuphazamiseka kwamadoda. Yingakho lesi sibonakaliso singenye yezindlela ezibalulekile ekuhloleni imiphumela yocwaningo olunjalo.

Amangqamuzana amancane ka-spermatogenesis nawo avame ukubizwa ngokuthi i-spermatogenic. Lokhu kufaka:

• ama-spermatogonia - stem cells, okuyisisekelo sokwakhiwa kwe-spermatocytes;
• i-spermatocytes 1 (ehlala ku-mitosis ngenxa yokuhlukaniswa kwamaseli angaphelele) nemiyalo emibili (faka 1 prophase meiosis, uqedele ukuhlukaniswa kokuqala, okwenza kube yi-spermatocytes yesibili);
• izidakamizwa (zibe neqoqo le-haploid lama-chromosomes futhi ngemva kokuguqulwa kwesakhiwo kuguqulwa zibe yi-spermatozoa).

Kufanele kuqaphele ukuthi amangqamuzana angashadile we-spermatogenesis akhona kunoma iyiphi i- spermogram. Ngakho, ngendlela evamile ukuhlushwa kwabo akufanele kudlule izigidi eziyisihlanu / ml umuthi. Kodwa-ke, ngezinye izikhathi, lapho kukhona ukwephulwa, ukudlula kwalesi sibonakaliso kuphawulwe izikhathi ezingu-10. Ucwaningo lwamuva luveze ukuthi le nkhomba ayiyona into enkulu yokuhlonza.

Okubaluleke nakakhulu ekunqumeni imbangela yalesi sifo kungukuqukethwe kwamaseli ku-cell cell, njenge-leukocytes, noma kunalokho, ifomu labo, njenge-neutrophils. Inani eliphelele lazo akumele lidlule i-1 million / ml. Uma kungenjalo, kukhona ukuthuthukiswa kokuphulwa okunjalo njenge- leukospermia, okuyinto ephazamisa kakhulu ikhono lama-germ cells wesilisa ukutshala.

Kuthiwani uma i-spermiogram yembula inombolo ekhulayo yamaseli e-spermatogenesis?

Njengoba sekushiwo ngenhla, ngisho nasemavivinini avamile e-spermatogenesis angeke abe khona esampheni ye-ejaculate. Kodwa-ke, uma inani labo eliphelele lidlula izigidi ezingu-5 / ml, khona-ke kuleli cala bakhuluma nge-pathology.

Loluhlobo lokuphula umthetho ukwehluleka kwenqubo yokwakhiwa kwe-spermatozoa. Ngenxa yalokhu, isilwane sitholakala kulesidoda esine-morphology engavamile (ukungabi khona kwe-flagella, i-flagellum kabili, ikhanda eliphindwe kabili, njll. I-spermatozoa enjalo ayikwazi ukutshala, ngenxa yokuphulwa komsebenzi wabo wamandla.

Ezimweni ezinjalo, umuntu ukwelashwa okunqunyiwe, okuhloswe ukuba kube nokujwayelekile kwe-spermatogenesis, okuyiyokuqala, okutholakala ngokuqokwa kwezidakamizwa ze-hormone.

Ngakho-ke, kungashiwo ukuthi ukutholakala kwe-spermogram yamangqamuzana omzimba we-spermatogenesis akuyona ukwephulwa uma ukuhlushwa kwabo kungadluli esimisweni esenziwe.
