Spermatogenesis - chii ichi?

Spermatogenesis - kunzwisisa nzira hono, umo paumbwe dzisingaoneki gonocytes (primordial utachiona sero). Zvaive munguva kuyaruka anotanga ndichibvunza Danho racho kukura, uye muitiro mberi kusvikira pakukwegura. Full vakaparadzana dzisingaoneki kukura kutenderera kunoitika Paavhareji kamwe ose 3 months.

Zviri majini zvinhu zviri urume yevanhu. Uyezve, chero pfungwa akasimba pabonde upenyu kunokanganisa chokubereka hwake. Naizvozvo, nzira iyo masero vari aumba kubva spermatogenesis, kunyatsofungwa.

An dzinonakidza Chokwadi ndechokuti mazuva ose testes aumbwa dzisingaoneki masero vanenge mamiriyoni 200, uye zvimwe hafu kuti dzinenge mamiriyoni 100 dzisingaoneki.

danho

Izvi zvakadaro kushaika kuti chakaipa nokushanda kwenhengo gono muviri muitiro unogona kukamurwa zvitatu anokosha maitikiro ose spermatogenesis:

• The kutanga kwekupwanyiwa pakukura inonzi mitosis. Panguva iyi, chokuwanziridza kuti hunde masero ari gonads, vanonzi testes.
• Panguva Danho rechipiri imwe inorwara masero kushandurwa yomuzana hurongwa spermatocytes. Zvadaro, nhamba yavo kunowedzera, uye pashure pfupi vanopinda danho rokutanga meiosis.
• Muchikamu chinotevera pavaipfuura muitiro pane masero, kunzi wechipiri-hurongwa spermatocytes. Izvi, anoumba spermatids. Uye kare vari nemhaka zvimwe kuchinja dzikava dzisingaoneki.

Sertoli muchitokisi basa

Spermatogenesis - inofanira apo masero ari pedyo nevanhu Sertoli masero, izvo kuita zvinotevera mabasa:

• kusika Zvakanyanya Kunaka Panguva Yepamuviri nokuti kukura "tadpoles" nharaunda;
• secrete mvura, iyo inobatanidzwa kushanda manhu;
• zvifambiswe kuti masero okisijeni uye zvinovaka muviri;
• synthesized kunyorerana mapuroteni iyo transports testosterone muzvitokisi spermatogenic.

Uchitikurudzira, spermatogenesis muitiro hwakareba chaizvo uye zvakaoma, uye negoho yaro zvizere novimba basa rose muviri. Kana murume ari mutano, ane, maererano, dzisingaoneki zvakanaka. Zvinorevei izvi? Qualitative urume rine yakawanda zvimwe dzisingaoneki.

Chimwe chinoratidza spermatogenesis

Weboka okutodza mune iyi akafanirwa vainyatsotarisirwa. Kana kuchinja kunoitika spermatocytes, 46 okutodza muzvikamu zviviri. Saka, zviri okutodza, izvo akaunza vabereki, 23 vavo vari mumwe muchitokisi spermatids, uye imwe hafu - mune dzimwe. Saka, chibereko yemberi ine 50% kubva nemashoko ari baba uye 50% vanaamai.

Zvinhu chokuita chirongwa spermatogenesis

Spermatogenesis - inofanira kuti inoenderana dzezvakatipoteredza zvinofurira. Ndosaka padanho rimwe nerimwe kukura dzisingaoneki inogona kukanganiswa nematambudziko zvinhu.

Chokutanga, chikuru zvinhu uyu akasiyana mugadziriro tembiricha uye zvakapoteredza zvinofurira, mukuwedzera, ane mutengo mararamiro inotungamirira munhu.

An chinogamuchirika tembiricha kuti spermatogenesis iri 34 ° C. Zvinofadza kuti muna mukono scrotum kuti tembiricha anodzokororwa ainyanya nokuda ropa riyerere zvakakodzera.

Dzimwe nguva kunyange nokuda yakawedzera muviri tembiricha panguva unserious dzisingaoneki chirwere parameters vanogona yekudyidzana achiipa. Nyanzvi regai kuvakurudzira kushandisa zviri motokari pachigaro hita, sezvo izvi zvingavawo kukonzera kudzikira mune unhu dzisingaoneki.

Kuwedzera tembiricha, kuti simba pamusoro urume zvinokonzerwa zvimwewo.

Stress, mishonga, steroids, hormone kukundikana - zvose izvo zvinogona kukanganisa mashandiro uye kukosha makono dzisingaoneki yepamusoro. Saka, asati yokubereka mwana harifaniri kutora chero zvinodhaka, huta, shandisa steroids.

Kubva izvo zvichiri kunotsamira spermatogenesis nevanhu?

Kunyange nokuda yakasviba mhepo iri mumhepo pamusoro spermatozoa velocity anogona kudukupiswa. A refu uye kuramba vachionana makemikari anogona kuva chikonzero duku kushaya mbereko.

Kana kwenguva yakareba, hazvibviri vakaroorana pamuviri, kutanga achaongorora murume. Zvinotora urume pamusoro pachisara unonzi "urume".

Health zviratidzo zviri dzisingaoneki

Chaiye Kugadzirwa nhengo munhurume dzisingaoneki count pa 1 ml urume kunge vangasvika 20 Mill. Kuwanda dzisingaoneki anokwanisa ave akaenzana hafu nhamba. Asi kunyange muviri utano anogona kuvapo akaneta dzisingaoneki, hakusi aberration.

ongororo dzakaratidza kuti dzisingaoneki unhu kazhinji kunobva somatic zvirwere varume. Somuenzaniso, mwoyo uye vascular chirwere, BP uye kunyange ganda zvirwere kanganisa masero spermatogenic.

Masayendisiti Australian vakawana kuti zuva ukama kunokanganisa unhu dzisingaoneki. Avo vanotevera zano iri, vakawana kuti ufanane DNA kukuvara yakanga kuderedzwa 20%. Vaongorori akatsanangura iyi ndechokuti kurega dzisingaoneki DNA wakuvadzwa uye kwete kuwanikwa dzose bonde urema hwakadaro.

Kunyange vakabudirira pamuviri, vamwe vanachiremba vanokurudzira mazuva mashoma kuti varege zvepabonde. Izvi zvinoitwa kuti kuwedzera wevasungwa kuti basa uye chine musoro spermatozoa.

kweiyi spermatogenesis

nenhamba World nhasi ndechokuti chikamu varume kutambura kubva mwana zvakakwirira zvikuru. chechipiri munhu mumwe nomumwe nokuda imwe nguva kana zvachose chena. Uye ichi idambudziko chairo, nokuti kunyange ezvokunambira kunze kwomuviri waamai muchangosangana nzira hazvibviri pasina dzisingaoneki. Achivhara mbereko muvarume haatori nguva yakawanda, kusiyana hadzi hafu vanhu. Usatya vanachiremba, nekuti zvinokanganisawo kukwanisa kuva nevana.

Saka zvakakosha nguva kurapwa. The chiremba vakuudzeyi zvekuita kuita zvimwe zviito zvainanga panguva kweiyi spermatogenesis.

Spermatogenesis - inofanira kuti kwakaoma chaizvo kuti apore. Chokutanga, murume aizofanira kuva kuongorora zvizere nokuda nyanzvi uye kununura urume ongororo - detailed Kuongorora ejaculate, iyo inoshandiswa kuona varume wokubereka, kuonekwa zvirwere uye hormone zvirwere. Uyewo anogona kuwedzera dzisingaoneki kugadzirwa, vachiona imwe nzira, izvo zvinosanganisira marapirwo uye mishonga. Ekupedzisira zvinosanganisira gonadotropins - mahormone kuti waidzora kushanda gonads.

On maratidzirwo mahormone pamusoro muviri zvichanzi kurondedzerwa hereinafter.

Mirayiridzo inokosha kuzoita spermatogenesis

Dzoserai kushanda hono uye zvichida nyore nzira kuti haadi dzinodhura kuita. Heano mamwe acho:

• kuchengetwa Zvakanyanya Kunaka Panguva Yepamuviri tembiricha: usarega overheating of manhu;
• kudzivisa miitiro inokuvadza (kusvuta, kunwa doro);
• kudya kwakakodzera, iyo inosiya kukuvadza varume basa zvigadzirwa;
• kurambwa zvinogadzirwa kuti dzine yokuvirisa uye munuhwi enhancers;
• Hazvina varumbidzwa kushanda zvine chepfu;
• Kurambwa inorwisa mabhakitiriya uye antihistamines. Uye zvirokwazvo munguva kuzoita spermatogenesis nani kurega kushandisa chero zvinodhaka.

Kuti kunobatsirawo pamusoro spermatogenesis? Chokwadi, kudya zvinovaka muviri inoita basa rinokosha izvi.

zvinogadzirwa

Zvimwe zvokudya zvine mavhitaminzi kuti zvinobatsira maximize kuorera akasimba pabonde. Zvikurukuru, izvi zvinosanganisira:

• Yekotapeya. Rine mavhitaminzi E uye B6, uye folic acid. Ivo akamisa hormone maitiro uye kuwedzera libido.
• Green pizi asiparagasi. Vhitamini C, iyo iri zvigadzirwa izvi, kunonatsiridza dzisingaoneki motility.
• Madomasi, tsvuku bhuratifuru, visi. Dzavo chirungiso - lycopene, iyo inowedzera basa "tadpoles."
• Nhanga mbeu, oatmeal, mazai, oysters, nzungu. Zingi, izvo zviri pakati pavo anowedzera uwandu dzisingaoneki.
• Garlic. Selenium Rinowanikwawo ayo sezvamunoita, kudzivirira dzisingaoneki muchiwirirana uye kunonatsiridza kweropa.
• Ginger. Zvinokanganisawo kweiyi dzisingaoneki kugadzirwa.

Cherechedzai inofanira kubhadharwa kuti zvigadzirwa kuti ane folic acid. Hazvina chinokosha nedanho spermatogenesis. zhinji makuru folic asidhi rinowanikwa Citrus zvibereko, beets, nhanga, chibage, nenyemba, itsvo bhinzi. Zvakaratidza kuti unogona kugadzirisa zvaunodya kuitira kuti urume unhu zvichanaka pamusoro nguva.

Kuzvirega zvichikanganisa kunowanzoitika pakunyudutsa spermatogenesis?

Doro kunowedzera pachiyero munhukadzi pabonde mahormone. Naizvozvo, kana zvakakosha kuti munhurume dzokubereka basa, chinofanira kusiya kushandisa doro. Kusvuta anewo inokanganisa nedanho paumbwe spermatozoa.

Hazvina varumbidzwa kushandisa makabheji, gorosi bran, uye cruciferous miriwo, izvo vanobatsirawo kugadzirwa inonzi estrogen. It kutakura njodzi huru, uye mafuta zvokudya. Grilled nyama, mayonnaise, bhekoni, aizikirimu - zviri vavengi chaivo ngakuite dzokubereka nadzo.

izvi zvose zvinogona kukonzera nokuvhiringidzirwa spermatogenesis.

Sezvineiwo, uwandu dzisingaoneki zvinoderedza mu mumatsutso uye muchando, apo muzhizha vanova Mobile. Saka, maererano nenhamba, pamuviri inoitika zvakawanda muzhizha kupfuura chando.

Unique mashoko pamusoro dzisingaoneki

• Apo mumwe-nguva ejaculation nevanhu mashizha vanenge hafu nendiro dzisingaoneki.
