Indoda
Umuntu omdala wesilisa womuntu . Ngaphambi kokuba mdala, umuntu wesilisa ubizwa ngomfana ( ingane yesilisa noma eyeve eshumini nambili ).
Njengazo zonke izilwane ezincelisayo zesilisa, ufuzo lomuntu ngokuvamile luthola i- X<span typeof="mw:Entity" id="mwIw"> </span>i-chromosome evela kumama kanye no- Y<span typeof="mw:Entity" id="mwJQ"> </span>i-chromosome evela kubaba. Umbungu wesilisa ukhiqiza amanani amakhulu ama- androgens namanani amancane ama- estrogens kunombungu wesifazane.Lo mehluko kumanani ahlobene nalawa ma- steroids ezocansi ubhekene nomehluko womzimba ohlukanisa amadoda kwabesifazane .Ngesikhathi sokuthomba, ama-hormone akhuthaza ukukhiqizwa kwe-androgen aholela ekukhuleni kwezici zesibili zobulili, ngaleyo ndlela kukhombisa umehluko omkhulu phakathi kobulili.Lokhu kufaka phakathi ubukhulu bemisipha, ukukhula kwezinwele zobuso nokwakheka kwamafutha omzimba aphansi.
Anatomy Male is zihlukaniswa kusukela anatomy zesifazane yi uhlelo besilisa zokuzala, ehlanganisa umthondo, amasende, isidoda imbobo, wendlala indlala kanye epididymis, kanye seconday ubulili izici.
Kukhona okuhlukile okungenhla ngokuphathelene kobakhe futhi bulilimbili amadoda.
Ibhayoloji[hlela | Hlela umthombo]
Kubantu, ubulili bomuntu bunqunywa ngesikhathi sokukhulelwa ngezinto zofuzo ezithwelwe esitokisini sesidoda. Uma ingqamuzana lesidoda eliphethe i- X chromosome livundisa iqanda, inzalo ngokujwayelekile iyoba ngowesifazane (XX).Ngakolunye uhlangothi, uma isidoda sesidoda esithwele i- Y chromosome sifaka iqanda, inzalo iyoba ngowesilisa (XY).Isici sangempela sokunquma yisakhi sofuzo se-SRY, esivame ukutholakala ku-Y chromosome.Abantu abanesakhiwo esididayo sezakhi zofuzo noma somzimba kubhekiswa kubo njenge- intersex .Ama- aneuploidies ocansi e- chromosome, njenge- XYY syndrome, nawo angavela.
- Izinwele zobuso ;
- Izinwele zesifuba;
- Amahlombe avulekile;
- I-larynx ekhulisiwe (eyaziwa nangokuthi i -apula lika-Adam ); [1] futhi
- Izwi elijule kakhulu kunezwi lengane noma lowesifazane. [2]
Uhlelo lokuzala[hlela | Hlela umthombo]
Uhlelo lokuzala lwabesilisa lubandakanya izitho zangasese zangaphandle nangaphakathi.Izitho zobulili zangaphandle zesilisa ziqukethe ipipi, i-urethra yesilisa, ne-scrotum, kuyilapho izitho zangasese zesilisa zangaphakathi zinama-testes, i-prostate, i-epididymis, i-vesicle yesidoda, i-vas deferens, i-ejaculatory duct, ne-bulbourethral gland.
Umsebenzi wesistimu yokuzala yowesilisa ukukhiqiza isidoda, esithwala isidoda futhi ngaleyo ndlela imininingwane yezofuzo engahlangana neqanda ngaphakathi kowesifazane.Njengoba isidoda okungaphandle okungena sowesifazane kwesibeletho bese amashubhu fallopian kuqhubeka zalisa iqanda okwenzeka ibe umbungu noma ingane, iduna uhlelo zokuzala udlala kungekho eyayidingeka ngesikhathi sokukhulelwa.Ukutadisha ukukhiqizwa kwamadoda nezitho ezihambisanayo kubizwa nge- andrology.
Ezempilo[hlela | Hlela umthombo]
Yize ngokujwayelekile abesilisa behlushwa izifo eziningi ezifana nezabesifazane, banezifo ezithe ukuqhela uma kuqhathaniswa nabesifazane. Abesilisa banesikhathi esiphansi sokuphila namazinga aphezulu okuzibulala uma kuqhathaniswa nabesifazane.
Ubulili nokungena ocansini[hlela | Hlela umthombo]
Ubulili besilisa nokuheha kuyahlukahluka kuye ngomuntu, futhi indlela umuntu aziphatha ngayo kwezocansi ingathinteka ezintweni eziningi, kufaka phakathi ukucabanga okuguqukayo, ubuntu, ukukhuliswa namasiko.Ngenkathi iningi lamadoda lingabobulili obuhlukile, abambalwa abalulekile bangongqingili noma abesilisa nabesifazane .Amanye amadoda akhomba njengokuqonde kakhulu .
Amaphesenti amancane abantu ababelwe abesifazane ngesikhathi sokuzalwa angakhomba njengabesilisa (ngokuvamile ababizwa ngokuthi amadoda angama-transgender ).Ngokuphambene nalokho, abanye abantu ababelwe owesilisa ngesikhathi sokuzalwa bangakhomba njengowesifazane (ovame ukubizwa ngokuthi ungowesifazane we-transgender ).Abanye abantu ababelwe owesilisa ngesikhathi sokuzalwa bangakhomba futhi njengokungeyona kanambambili.Kukhona nabantu be-intersex abangakhomba njengabesifazane noma abesilisa.
