Loaʻa nā ʻōnaehana hānau kāne mai kahi hoʻonohonoho o nā mea kūloko a me waho, e hoʻokuʻu ana i nā homone, androgens, a mālama ʻia e ka lolo ma o ka hypothalamus, ka mea e hūnā ai i ka hormone hoʻokuʻu hoʻokuʻu gonadotropin a me ka pituitary, e hoʻokuʻu i ka follicle-stimulate and luteinizing hormone .

ʻO nā ʻano moekolohe mua, i hoʻopili ʻia me nā genital kāne, hana ʻia i ka wā o ka ulu ʻana o ka fetal a ua hoʻokumu ʻia nā mea kiʻekiʻe mai ka wā ʻōpio, ma waena o nā makahiki o 9 a me 14, ke lilo ke kino o ke keikikāne i kino kāne, kahi e ulu ai nā ʻōnaehana kāne. a me ke ʻano o ka ʻumiʻumi, lauoho ma ke kino a mānoanoa o ka leo.

He aha nā mea moekolohe kāne

1. Kakela

ʻO ka scrotum kahi ʻeke o ka ʻili lewalewa, nona ka hana o ke kākoʻo ʻana i nā testicle. Hoʻokaʻawale ʻia lākou e kahi septum, i hoʻokumu ʻia e nāʻiʻo muscle a i ka wā e ʻaelike ai, hiki i ka ʻili o ka ʻili scrotum, he mea nui ia no ka hoʻoponopono ʻana i ka mahana, ʻoiai aia i loko o nā testicle i hua ʻia ai ka sperm.

Hiki i ka scrotum ke mālama i ka mahana o nā testicle ma lalo o ke kino o ke kino, no ka mea aia ma waho o ka lua pelvic. Hoʻohui ʻia, i kekahi mau ʻano, e like me ke anuanu, ke ʻāpā cremaster, i hoʻokomo ʻia i loko o ka scrotum a kāpae i ka testicle, hoʻāla i nā testicle i ka wā o ke anuanu, e pale ana iā ia mai ke anuanu, a ʻo ia pū kekahi i ka wā e hoʻāla ai ka wahine.

2. Hōʻikeʻike

Loaʻa i nā kāne ʻelua mau testicle, ʻo ia nā lālā me kahi ʻano oval a ʻo ke ana e pili ana i 5 cm ka lōʻihi a me 2.5 cm ke anawaena o kēlā me kēia, e kaupaona ana ma kahi o 10 a 15 mau mika. ʻO kēia mau lālā i ka hana o ka hūnā ʻana i nā homone wahine e pili ana i ka spermatogenesis, ʻo ia hoʻi ka hoʻokumu ʻana o ka sperm, a hoʻonāukiuki i ka hoʻomohala ʻana i nā ʻano moekolohe kāne.

Hoʻohuli ʻia ka hana o nā testicle e ka ʻōnaehana hopohopo waena, ma o ka hypothalamus, kahi e hūnā i ka hormone hoʻokuʻu hoʻokuʻu gonadotropin (GnRH), a me ka pituitary, e hoʻokuʻu i nā follicle-stimulate (FSH) a me nā luteinizing (LH) hormones.

I loko o nā testicle, aia nā tubules seminiferous, kahi e loaʻa ai ka ʻokoʻa o nā hunaola germ i loko o spermatozoa, a laila e hoʻokuʻu ʻia i loko o ka lumen o nā tubules a hoʻomau i ke oʻo ʻana ma ko lākou ala ma o nā kahe o ka ʻōnaehana hānau. Hoʻohui ʻia, loaʻa i nā tubules seminiferous nā hunaola Sertoli, nā mea e mālama i ka pono a me ke kō ʻana o nā hunaola germ, a me nā mea i hoʻopuni ʻia e hoʻopuni i kēia mau tubula i nā pūnaewele Leydig, kahi e hana ai i ka testosterone.

3. Nā kelena moe kolohe

ʻO kēia mau ʻōpū ke kuleana no ka hūnā ʻana i ka nui o ka semen, a he mea nui ia no ka lawe ʻana a me ka meaʻai o ka sperm a me ka lubrication o ka peni.

• Nā vesicle seminal:he mau hale ia ma hope o ke kumu o ka ʻai a ma mua o ka poli a hana i kahi wai nui e hoʻomaʻamaʻa i ka pH o ka urethra i loko o nā kāne a hoʻoliʻiliʻi i ka acidity o ka ʻōnaehana wahine, no laila e pili ia me ke ola o ka sperm. Eia hou, he fructose kona i loko o kāna mea i haku ʻia, kahi mea nui e hana i ka ikehu no ko lākou ola a me ka locomotion, i hiki ai iā lākou ke momona i ka hua manu;
• Moekolohe:Aia kēia hale ma lalo o ka puhā, hoʻopuni i ka urethra āpau a hūnā i kahi wai waiū e hāʻawi i kāna hoʻopili ʻana ma hope o ka ejaculation. Hoʻohui ʻia, loaʻa pū kekahi i nā mea i hoʻohana ʻia no ka hana ʻana i ka ikehu, e hāʻawi i ka neʻe a me ke ola o ka sperm.
• Nā gland bulbourethral a i ʻole nā ​​gland o Cowper: aia kēia mau glands ma lalo o ka prostate a loaʻa nā kahe e hāmama i ka ʻāpana spongy o ka urethra, kahi e hūnā ai lākou i kahi mea e hōʻemi ai i ka acidity o ka urethra i hoʻokumu ʻia e ka mimi. Hoʻokuʻu ʻia kēia mea i loko o ka huhū wahine, a he hana lubricating kekahi, e kōkua ana i ka moekolohe.

4. peni

ʻO ka peni kahi hale cylindrical, i haku ʻia i nā kino kai a me nā kino spongy, aia ma kahi o ka urethra. Ma ka wēlau o ka peni, aia nā glan, uhi ʻia e ka ʻōmaka, nona ka hana o ka pale ʻana i kēia ʻāina.

Ma waho o ke kōkua ʻana i ke kahe ʻana o ka mimi, he hana nui kā ka peni ma ka moekolohe ʻana, nā mea e hoʻonāukiuki ai i nā aʻa e hoʻoinu i nā kino o ke ana a me nā iwi spongy a hoʻonui i ka nui o ke koko i kēia wahi, ke alakaʻi nei hoʻi i kahi paʻakikī o ka peni, hoʻonāukiuki i kona komo ʻana i loko o ka aʻa liʻiliʻi i ka wā o ka moekolohe.

Pehea e hana ai ka Hormone Control

Mālama ʻia ka hana kāne kāne e nā hormones e hoʻoulu ai i ka ulu ʻana o nā mea hānau, ka hana ʻana o ka sperm, ka hoʻomohala ʻana i nā ʻano moekolohe ʻelua a me ka moekolohe.

Hoʻopili ʻia ka hana o nā testicle e ka hypothalamus, ka mea e hoʻokuʻu i ka hormone hoʻokuʻu hoʻokuʻu gonadotropin (GnRH), e hoʻonāukiuki i ka pituitary gland e hūnā i ka hormone luteinizing (LH) a me ka follicle-stimulate hormone (FSH). Hana pololei kēia mau hormoni i ka testicle, ka mālama ʻana i ka spermatogenesis a me ka hana ʻana o androgen, estrogen a me nā hormones progesterone.

Ma waena o nā mea hope loa, ʻo ka nui o nā hormoni i loko o nā kāne he androgens, me ka testosterone ʻo ia ka mea nui a ʻo ka mea e pili ana i ka hoʻomohala ʻana a me ka mālama ʻana i nā ʻano moekolohe kāne, e hoʻohuli nei hoʻi i ka hoʻokumu ʻana o ka sperm.

He mana ko Androgens i ka hoʻomohala ʻana i nā ʻano moekolohe mua a me nā lua. Hana ʻia nā ʻano moekolohe ma mua, e like me nā kāne a me nā kino moekolohe o loko, i ka wā o ka ulu ʻana o ka embryo a me nā ʻano moekolohe lua mai ka wā ʻōpio.

Kū ʻo Puberty ma kahi o 9 a 14 mau makahiki o ka makahiki, e hoʻonui ana i ke kino, ka ulu ʻana o ka ʻumiʻumi a me ka lauoho pubic a me ke koena o ke kino, ka mānoanoa o nā kaula leo a me ka puka ʻana o ka makemake moekolohe. Eia hou, aia ka ulu ʻana o ka peni, scrotum, seminal vesicle a me ka prostate, hoʻonui i nā huna sebaceous, kuleana no ka huehue.

E ʻike pū i ka hana o ka ʻōnaehana hānau wahine.
