Spermatogenesis: he aha ia a pehea e hana ai nā pae nui

Anter

• Nā papa nui o ka spermatogenesis
• 1. pae Germinative
• 2. Wā ulu
• 3. Ke kuʻi ʻana
• 4. ʻĀpana ʻokoʻa
• Pehea e hoʻoponopono ʻia ai ka spermatogenesis

Kūlike ʻo Spermatogenesis i ke kaʻina hana o ka sperm, ʻo ia nā kāne e pili ana i ka hoʻoulu hua. Hoʻomaka ka hoʻomaka ʻana o kēia kaʻina hana a puni ka makahiki o 13, hoʻomau ʻia i ke ola o ke kāne a me ka hōʻemi ʻana i ka ʻelemakule.

ʻO Spermatogenesis kahi hana i hoʻokele nui ʻia e nā homone, e like me testosterone, luteinizing hormone (LH) a me follicle stimulate hormone (FSH). Hana kēia hana i kēlā me kēia lā, e hana ana i nā mano o ka sperm i kēlā me kēia lā, i mālama ʻia i ka epididymis ma hope o kāna hana ʻana i nā hōʻike.

Nā papa nui o ka spermatogenesis

ʻO Spermatogenesis kahi hana paʻakikī e mau ma waena o 60 a 80 mau lā a hiki ke hoʻokaʻawale ʻia i kekahi mau ʻanuʻu:

1. pae Germinative

ʻO ka lā germinative ka pae mua o ka spermatogenesis a hiki i ka wā e hele ai nā hunaola germ o ka wā embryonic i nā testicle, kahi e noho ʻole ai lākou a ʻeleu ʻole hoʻi, a ua kapa ʻia ʻo spermatogonias.

Ke hiki i ke keiki kāne i ka wā ʻōpio, ʻo ka sperm, ma lalo o ka mana o nā hormones a me nā hunaola Sertoli, aia i loko o ka testis, e ulu ikaika aʻe ma o nā mahele o ka cell (mitosis) a hāpai i nā spermatosit mua.

2. Wā ulu

ʻO nā spermatocytes mua i hoʻokumu ʻia i ka germinative phase e hoʻonui i ka nui a hana i ke kaʻina o ka meiosis, no laila e pālua ʻia kā lākou mea kūlohelohe, a ʻike ʻia he spermatosittes lua.

3. Ke kuʻi ʻana

Ma hope o ke kūkulu ʻia ʻana o ka spermatocyte lua, hana ke ʻano o ke ʻano ʻana e hāpai i ka spermatoid ma o ka mahele meiotic.

4. ʻĀpana ʻokoʻa

Kūlike i ka wā o ka hoʻololi o ka sperm i sperm, a ʻoi paha ma kahi o 21 mau lā. I ka wā o ka ʻokoʻa, kahi hiki ke kapa ʻia ʻo spermiogenesis, ua kūkulu ʻia ʻelua mau hale koʻikoʻi:

• ʻAcrosome: he hanana i kū i ke poʻo o ka sperm e loaʻa ana i kekahi mau enzyme a ʻae i ka sperm e komo i ka hua manu a ka wahine;
• ʻO ka hahau: ke kūkulu e ʻae ai i ka neʻe o ka sperm.

Me ka loaʻa o kahi flagellum, ʻaʻohe motility o ka sperm i hana ʻia a hiki i ko lākou hele ʻana i ka epididymis, ka loaʻa ʻana o ka motility a me ka momona ma waena o 18 a me 24 mau hola.

Pehea e hoʻoponopono ʻia ai ka spermatogenesis

Hoʻonohonoho ʻia ʻo Spermatogenesis e kekahi mau hormones ʻaʻole makemake wale i ka ulu ʻana o nā mea moekolohe kāne, akā ka hana ʻana o ka sperm. ʻO kekahi o nā hormones nui he testosterone, ʻo ia kahi hōmona i hana ʻia e nā puʻuwai Leydig, ʻo ia nā pūnaewele i loaʻa i nā hōʻike.

Ma waho o ka testosterone, he mea nui ka hormone luteinizing (LH) a me ka hormone stimulate follicle (FSH) no ka hana sperm, no ka mea hoʻonāukiuki lākou i nā pūnaewele Leydig e hana testosterone a me nā huna Sertoli, no laila aia kahi hoʻololi o spermatozoa i spermatozoa.

Hoʻomaopopo i ka holo ʻana o ka hoʻoponopono hormonal o ka ʻōnaehana hānau kāne.
