Ziwalo zoberekera zamwamuna zimachokera ku ziwalo zamkati ndi zakunja, zomwe zimatulutsa mahomoni, ma androgens, ndipo amayendetsedwa ndi ubongo kudzera mu hypothalamus, yomwe imatulutsa timadzi tomwe timatulutsa gonadotropin ndi pituitary, yomwe imatulutsa timadzi tomwe timapangitsa kuti tibereke .

Makhalidwe oyambilira ogonana, omwe amaphatikizira maliseche amphongo, amapangidwa nthawi yakukula kwa fetal ndipo yachiwiri imapangidwa kuyambira kutha msinkhu, azaka zapakati pa 9 ndi 14, pomwe thupi la mnyamatayo limakhala lamwamuna, momwe ziwalo zoberekera zamwamuna zimakhalira, komanso mawonekedwe a ndevu, tsitsi mthupi lonse komanso kukulira kwa mawu.

Kodi ziwalo zoberekera za abambo ndi ziti?

1. Mpukutu

Chotupa ndi thumba la khungu lotayirira, lomwe limagwira ntchito yothandizira machende. Amagawanika ndi septum, yomwe imapangidwa ndi minofu ya mnofu ndipo ikagwirizana, imayambitsa makwinya a khungu la minyewa, lomwe ndilofunika kwambiri pakuthana ndi kutentha, popeza ndi machende omwe umuna umapangidwa.

Mphuno imatha kutentha kutentha kwa machende pansi pa kutentha kwa thupi, monga kunja kwa mchiuno. Kuphatikiza apo, m'malo ena, monga kuzizira, minofu ya cremaster, yomwe imalowetsa m'matumbo ndikuyimitsa machende, imakweza machende pakuwonekera kuzizira, kuletsa kuzizira, komwe kumachitikanso mukadzutsa chilakolako chogonana.

2. Machende

Amuna nthawi zambiri amakhala ndi machende awiri, omwe ndi ziwalo zokhala ndi mawonekedwe owulungika ndipo amayeza pafupifupi 5 cm m'litali ndi 2.5 cm m'mimba mwake mulingo uliwonse, wolemera pafupifupi magalamu 10 mpaka 15. Ziwalozi zimagwira ntchito yobisa mahomoni ogonana omwe amapezeka mu spermatogenesis, omwe amapangidwa ndi umuna, komanso omwe amalimbikitsa kukula kwa zikhalidwe zogonana amuna.

Kugwira ntchito kwa machende kumakhudzidwa ndi dongosolo lamanjenje lamkati, kudzera mu hypothalamus, yomwe imatulutsa mahomoni otulutsa gonadotropin (GnRH), ndi pituitary, yomwe imatulutsa mahomoni opatsa mphamvu (FSH) ndi luteinizing (LH).

Mkati mwa machendewo muli ma tubules osakanikirana, pomwe kusiyanasiyana kwa ma cell a majeremusi mu spermatozoa kumachitika, kenako kumasulidwa ndikuwala kwa ma tubules ndikupitilizabe kukhwima panjira yawo kudzera m'mabande a ziwalo zoberekera. Kuphatikiza apo, ma tubules omwe ali ndi seminiferous amakhalanso ndi maselo a Sertoli, omwe amachititsa kuti tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda, komanso minofu yomwe imazungulira ma tubuleswa imakhala ndi maselo a Leydig, omwe amapanga testosterone.

3. Zowonjezera zogonana

Matendawa ali ndi udindo wobisa umuna wambiri, womwe ndi wofunikira kwambiri pakunyamula ndi kupatsanso thanzi la umuna komanso pakondedwe ka mbolo:

• Zovala za Seminal:izi ndizomwe zili kumbuyo kwa chikhodzodzo komanso kutsogolo kwa rectum ndikupanga madzi ofunikira kuti asinthe pH ya urethra mwa amuna ndikuchepetsa acidity ya maliseche achikazi, kuti ikhale yogwirizana ndi moyo wa umuna. Kuphatikiza apo, ili ndi fructose momwe imapangidwira, yomwe ndikofunikira kuti ipange mphamvu kuti ipulumuke ndikutuluka, kuti athe kuthira dzira;
• Prostate:nyumbayi ili pansi pa chikhodzodzo, ikuzungulira mkodzo wonse ndipo imatulutsa madzi amkaka omwe amathandiza kuti magazi atseke pakatha. Kuphatikiza apo, ilinso ndi zinthu zomwe zimagwiritsidwa ntchito popanga mphamvu, zomwe zimathandizira kuyenda ndi kupulumuka kwa umuna.
• Matumbo a Bulbourethral kapena ma gland a Cowper: tiziwalo timene timapezeka pansi pa prostate ndipo tili ndi timadontho tomwe timatseguka m'chigawo cha siponji cha mkodzo, momwe zimatulutsa chinthu chomwe chimachepetsa acidity ya mkodzo yomwe imayambitsidwa ndi mkodzo. Izi zimatulutsidwa panthawi yogonana, yomwe imakhalanso ndi ntchito yotsekemera, yothandizira kugonana.

4. Mbolo

Mboloyo ndimapangidwe ozungulira, opangidwa ndi matupi a cavernous ndi matupi otsekemera, omwe amakhala mozungulira mtunda. Kumapeto kwa mbolo, pali glans, yokutidwa ndi khungu, lomwe limagwira ntchito yoteteza dera lino.

Kuphatikiza pakuthandizira kutuluka kwa mkodzo, mbolo imagwiranso ntchito yofunikira pakugonana, yomwe zoyambitsa zake zimayambitsa kukhathamira kwamitsempha yake yomwe imathirira matupi a cavernous ndi siponji ndikupangitsa kuchuluka kwa magazi mderali, komanso kutsogolera mpaka kuuma kwa mbolo, ndikulowetsa kulowa kwake mumtsinje wamaliseche panthawi yogonana.

Momwe Kudyetsa Hormone Kumagwirira Ntchito

Kubereketsa kwamwamuna kumayang'aniridwa ndi mahomoni omwe amalimbikitsa kukula kwa ziwalo zoberekera, kupanga umuna, kukula kwa mikhalidwe yachiwiri yogonana komanso machitidwe ogonana.

Kugwira ntchito kwa machende kumayang'aniridwa ndi hypothalamus, yomwe imatulutsa mahomoni otulutsa gonadotropin (GnRH), opangitsa kuti khungu la pituitary litulutse luteinizing hormone (LH) ndi hormone yolimbikitsa (FSH). Mahomoniwa amachita molunjika pa testicle, kuwongolera spermatogenesis ndikupanga ma androgen, estrogen ndi progesterone mahomoni.

Zina mwazomalizazi, mahomoni ochulukirapo mwa amuna ndi ma androgens, testosterone ndiyo yofunikira kwambiri komanso yokhudzana ndi kukula ndi kusamalira mikhalidwe yogonana yamwamuna, zomwe zimathandizanso pakupanga umuna.

Androgens imathandizanso pakukula kwamakhalidwe oyambira komanso achiwiri. Zizindikiro zoyambirira zogonana, monga ziwalo zakunja zakunja ndi zamkati zamkati, zimapangidwa pakukula kwa mwana wosabadwa ndipo zikhalidwe zogonana zachiwiri zimapangidwa kuyambira kutha msinkhu.

Kutha msinkhu kumachitika pafupifupi zaka 9 mpaka 14 zakubadwa, kumapangitsa kusintha kwa mawonekedwe amthupi, kukula kwa ndevu ndi ubweya wam'mimba ndi thupi lonse, kukulitsa kwa zingwe zamawu komanso kutuluka kwa chilakolako chogonana. Kuphatikiza apo, palinso kukula kwa mbolo, chikopa, zotupa zam'mimba ndi Prostate, zotupa zowonjezereka, zomwe zimayambitsa ziphuphu.

Onaninso momwe njira yoberekera yaikazi imagwirira ntchito.
