Maselo a spermatogenesis

Pofuna kudziwa zomwe zimayambitsa kusabereka kwa anthu okwatirana, onse awiriwa amayesedwa. Mkulu wa mayesero kwa amuna pa nkhaniyi ndi spermogram. Kafukufuku wamtundu uwu ndi cholinga chokhazikitsa zitsanzo za maselo ogonana a ejaculate, omwe nthawi zambiri amakhala osowa mu kapangidwe kake. Makamaka zimaperekedwa kwa maselo a spermatogenesis, omwe amasintha kukhala spermatozoa.

Kodi kupangidwa kwa maselo a amuna amtundu wanji?

Asanayambe kunena za maselo ambiri a spermatogenesis muyeso kapena mlingo akhoza kukhalapo mu umuna, tiyeni tione mwachidule momwe kukula kwa spermatozoon.

Choncho, mapangidwe a maselo a amuna amtundu wa amuna amayamba pafupifupi zaka 12 ndipo amatha kufikira ukalamba, m'moyo wonse wa munthu. Pa nthawi yomweyi, ndi zachilendo kuganiza kuti nthawi ya spermatogenesis ili pafupi masiku 75.

Mapangidwe a maselo ammimba amayamba mwachindunji mkati mwa miyala yotulutsa convoluted seminiferous yamatenda. Madzi awo onse amagawanika ndi septum yapadera mpaka awiri. Mmodzi mwa magawo awiriwa a spermatogenesis alipo, ndipo kachiwiri - spermatogonia, yomwe imayambitsa spermatozoa. Kawirikawiri, khungu limodzi lili ndi maselo oposa biliyoni.

Ndi maselo ati omwe ali aang'ono ndipo ayenera kukhala ndi zochuluka bwanji mu spermogram?

Monga lamulo, kupezeka kwa maselo ambiri a spermatogenesis kumabweretsa chitukuko cha mavuto pakati pa amuna. Ichi ndichifukwa chake chizindikiro ichi ndi chimodzi mwazofunikira pakufufuza zotsatira za phunziroli.

Maselo ang'onoang'ono a spermatogenesis amatchedwanso spermatogenic. Izi zikuphatikizapo:

• maselo a spermatogonia , omwe ndi maziko a mapangidwe a spermatocytes;
• spermatocytes 1 (sungani mu mitosis chifukwa cha kusagwirizana kwa maselo osakwanira) ndi maulamuliro awiri (lowetsani 1 prophase meiosis, malizitsani magawo oyambirira, ndikupanga monga spermatocytes 2);
• spermatids (ali ndi haploid ya ma chromosomes ndipo pambuyo pa kusintha kwamasinthidwe amasandulika kukhala spermatozoa).

Ndikoyenera kudziwa kuti maselo osakwatira a spermatogenesis alipo mu spermogram iliyonse . Choncho, mwachizoloŵezi chisamaliro chawo sayenera kupitirira mamiliyoni asanu / ml wa umuna. Komabe, nthawi zina, pakakhala kuswa, kuwonjezerapo kwa chizindikiro ichi kumawonekera kangapo. Kafukufuku wam'mbuyo posonyeza kuti chizindikiro ichi si cha mtengo wapatali woyeza.

Chofunika kwambiri pakuzindikira chomwe chimayambitsa matendawa ndi zomwe maselo ali mumimba ya umuna, monga leukocyte, kapena kuti, mawonekedwe awo, monga neutrophils. Chiwerengero chawo sichiyenera kupitirira 1 million / ml. Kupanda apo, pali chitukuko cha kuphwanya koteroko monga leukospermia, zomwe zimakhudza kwambiri mphamvu ya maselo aamuna kuti asambe.

Nanga bwanji ngati spermiogram inasonyeza kuchuluka kwa maselo a spermatogenesis?

Monga tanenera kale, ngakhale m'maselo achibadwa a spermatogenesis sangathe kupezeka mu chitsanzo cha ejaculate. Komabe, ngati chiwerengero chawo chiposa 5 miliyoni / ml, ndiye kuti akuyankhula za matenda.

Mtundu uwu wa kuphwanya ndiko kulephera kwa njira yopanga spermatozoa. Chifukwa cha izi, nyemba imapezeka mu umuna ndi maonekedwe osasinthika (mawonekedwe): kusowa kwa mbendera, mbendera ziwiri, mutu wambiri, ndi zina zotero. Spermatozoa imeneyi silingathe kufota manyowa chifukwa cha kuphwanya mpweya wawo.

Zikakhala choncho, mwamuna amalembedwa chithandizo, chomwe chimapangidwira kuti chidziwitso cha spermatogenesis chikhale chokhazikika, chomwe choyamba chimachitika poikidwa mankhwala osokoneza bongo.

Motero, tinganene kuti kukhalapo mu spermogram ya maselo osakanikirana a spermatogenesis si kuphwanya ngati kusungidwa kwawo sikupitirira chikhalidwe chokhazikika.
