Sperm - hale, hana, anomalies

ʻO Spermatozoa nā pūnaewele germ kāne e pono ai no ka hoʻohua ʻana i ka wahine. I nā kāne, loaʻa iā lākou ka lōʻihi o 60 microns a ua hoʻokumu ʻia i ke kaʻina hana spermatogenesis. He 16 mau lā ka lōʻihi, akā he 2 mau mahina e hana ai i ka sperm makua. Inā loaʻa nā maʻi i ka wā o ka pōʻai mua, hiki ke emi ka maikaʻi o ka sperm.

1. Sperm - hale

Hoʻokumu ʻia ka spermatozoa oʻo loa poʻo a ʻāʻī a ʻo ko lākou lōʻihi ma kahi o 60 µm. He ʻano oval ke poʻo sperm. ʻO ka lōʻihi ma kahi o 4-5 microns, ākea 3-4 microns. I loko, aia kahi nucleus cell i loaʻa ka DNA a me kahi acrosome. Aia i loko o ka acrosome nā enzymes proteolytic kuleana no ke komo ʻana ma o ka membrane alohilohi o nā cell germ wahine. ʻO Vitek kahi mea kuleana no ka neʻe ʻana o ka spermatozoa. Aia kēia mea i ka ʻāʻī a me kahi mea hoʻokomo. ʻO ka ʻāʻī ka ʻāpana mua o ka twine a hoʻopili i ke poʻo sperm i ke koena o ka twine. ʻO ka mea hoʻokomo, ma ka ʻaoʻao ʻē aʻe, he mea maʻalahi ʻē aʻe o ka hoʻolālā sperm.

2. Sperm - hana

ʻO ka hana ʻana o ka spermatozoa i loko o nā kāne i kapa ʻia ke kaʻina hana spermatogenesis. I ka wā o ka wā ʻōpio i nā keikikāne, ua hoʻokumu ʻia nā cell i loko o nā paipu seminal mai nā pūlima ma hope o ka mitosis, i kapa ʻia. spermatogonia. A laila hoʻokaʻawale ka follicle-stimulating hormone ma o ka mitosis. I kēia pae, aia kauoha ʻia nā spermatocytes XNUMX. Ma hope mai, hele nā ​​spermatocytes mua i ke kaʻina hana o ka meiosis kahi i hana ʻia ai kauoha ʻia nā spermatocytes XNUMX.

Hele kēia mau pūnaewele i ke kaʻina meiosis a hana hou sperm. A laila lilo lākou i spermatozoa me ka helu haploid o nā chromosomes. I ke kaʻina hana holoʻokoʻa, emi ka nui o ka cytoplasm a me ka helu o nā organelles cell. He poʻo ka nucleus o ke kelepona, a hoʻololi kekahi hapa o ka mea hana Golgi i acrosome i loaʻa nā enzymes pono no ke komo ʻana i loko o ka hua manu.

ʻO ke kaʻina holoʻokoʻa o ka spermatogenesis aia ma lalo o ka mana hormonal o ka testosterone, a ʻo ke kaʻina holoʻokoʻa o ka spermatogenesis kanaka e pili ana i nā lā 72-74.

3. Sperm - anomalies

ʻO Spermatozoa nā pūnaewele e pono ai no ke kaʻina fertilization. Eia nō naʻe, aia nā ʻano mea like ʻole e hiki ke hoʻopilikia i kēia mau cell, e alakaʻi ana i ka hoʻāʻo ʻole e hāpai. Ma waena o kēia mau hewa, hiki i kekahi ke hoʻokaʻawale i nā mea e pili ana i kahi ʻano kūlohelohe, ka nui, ka nui o ka sperm i hana ʻia a i ʻole ka mobility. No ke ʻano o ka spermatozoa, hiki i nā hemahema ke hoʻopilikia i nā mea āpau o ko lākou ʻano a ua kapa ʻia ʻo teratozoospermia. Ma muli o ka helu o ka sperm i loko o ka ejaculate, hiki ke ʻike ʻia kēia mau mea: azoospermia (ka nele o ka spermatozoa i ka ejaculate), oligospermia (haʻahaʻa loa ka helu sperm i loko o ka ejaculate) a cryptozoospermia (ke ʻike ʻia ka spermatozoa hoʻokahi i loko o ka ejaculate). Hoʻokaʻawale ʻia nā maʻi o ka nui o ka semen i: aspermia (ke hoʻokuʻu ʻia ka sperm ma lalo o 0,5 ml i hoʻokahi ejaculation), hypospermia (inā emi ka nui ma mua o 2 ml), hyperspermia (inā ʻoi aku ka nui o ka sperm ma mua o 6 ml). ʻO Asthenozoospermia kahi huaʻōlelo i hoʻohana ʻia e wehewehe i ka motility sperm abnormal, ʻoiai e like me nā lula o kēia manawa, ʻoi aku ma mua o 32% o ka sperm e hōʻike i ka neʻe i mua.
