Zvinoshamisa, asi chokwadi: nokukurumidza kana kuti gare gare anenge munhu wose anofunga nezvekuenderera kwemhuri. Uye vamwe varume vanorota nevana kupfuura vakadzi vavo. Asi kana zvasvika mukugadzirira kubata pamuviri, vanababa vemangwana vanotenda kuti havana chavanoita munguva ino. Uye ivo vakakanganisa. Varume pamwe chete nevakadzi vanobatsirana ku genetics yomwana uye vane basa rehutano hwemwanakomana wavo kana mwanasikana wavo wemangwana.
Mukuwedzera kune mageneti, kune chimwe chinhu chakakosha chekugadzirira kwekudzorerwa kwemhuri. Kubva kumurume muzviitiko zvizhinji mukana wekubata unotaridzika. Sezvo nhamba dzichiratidza, munenge hafu yematambudziko ekudzivirira hazviitike nekuda kwekudzivirira kwemunhu. Uyewo, chiratidzo chikuru chekubereka chibereko chehuta, iyo inotarirwa nemiganhu iyo sehamba ye spermatozoa, kufamba kwavo, chimiro (morphology) nekubudirira.
Kuti unzwisise kuti sei basa rakadaro rinokosha rinowedzerwa nemafungiro aya, ngatitariye kuti kutora pamuviri kunowanikwa sei.
Spermatozoa inopinda mu uterine cavity 30-60 maminitsi mushure mekuvhara, uye pashure peawa 1.5-2 maawa vanopinda mu ampulla ye uterine tube. Evha inowanikwa pano pamusvondo maawa masere mushure mekuvhara. Ipapo zera rinosungira kana kufa. Apo spermatozoa "inowana" mazai, inonamatira kuhombe yayo, asi inopinda muiyo masero, sekutonga, imwechete spermatozoon inogoneka. Nezveruzhinji, shell inenge isingakwanisi. Mushure mokunge spermatozoon inopinda muzai, nucleus yayo inosanganiswa nechepakati reii, uye chromosomes yababa inogadzira imwe chete yakagadzirirwa namai chromosomes. Panenge rimwe zuva mushure meizvi, sero rinoguma rinotanga kuparadzanisa - danho rokutanga rekuberekwa kwemafuro rinotanga.
Mukutaura, zvinhu zvose zviri nyore. Asi chokwadi chiri chakaoma zvikuru. Iyo spermatozoon ine zviduku zviduku zvikuru (iri 8 zvishoma zvishoma pane pixel). Kuti "uwane" kuneii, chirume chinoda kukunda kfupi, iyo inopfuura 3636 times. Kana munhu aifanira kufamba nenzira iyoyo, aifanira kubva kuMoscow kuenda kuVoronezh. Unofunga kuti vakawanda vaizogadzirisa basa iri here? Ndicho chikonzero nei zvakakosha kuti spermatozoa inofamba uye ine sarudzo yakarurama. Uye kunyanya mbeu iyi mumumvuri, iyo inowedzera mukana wekuti imwe yei inokwanisa kusvika pachinangwa.
Ngatitaurire zvakawanda pamusoro pechiratidzo chega chega.
Zviratidzo zvekubereka mwana
Sezvatave tatoona, kuitira kuti tisangane ne ovum, spermatozoa inofanirwa kufamba nechekare uye neimwe nzira. Spermatozoons inofungidzirwa isingabatsiri kana tsvimbo dzavo dzedumine dzine circular kana oscillatory kufamba munzvimbo imwe (manezhnye kana pendulum) - munyaya iyi spermatozoon haigoni kusvika ku ovum. Mhando dzemazuva ose dzinofungidzirwa, umo 40% ye spermatozoa inoshandiswa.
Izvo zvakasarudzwa zvinogadzirisa kwete chete kukwanisa kufamba, asiwo kukwanisa kuisa mazai. Iro spermatozoon inofungidzirwa kuti morphologically yakarurama kana musoro wayo une ruvara rwakasvibiswa nemafuta ane acrosome inotsanangurwa zvakanaka. An acrosome inobata membrane ine enzymes iyo inopedza mazai evha kupinda mukati me spermatozoon mairi. Iyo acrosome inowanzofanira kutora 40-70% yemusoro. Iyo spermatozoon haifaniri kunge isina kukanganisa kwemusoro, mutsipa, pakati nepakati muswe.
Mafungiro epermatozoa mu ejaculate anokosha zvikuru. Mamiriro ezvinhu ayo mamiriyoni makumi mana nemakumi mana ekurarama spermatozoa kana kuti akawanda anowira pamamiriyoni imwe emuviri anonzi anobereka kubereka. Kuti mbeu ibudirire, anenge mamirioni gumi spermatozoa anofanira kupinda muchibereko.
Nzira yekuongorora sei kubereka kwevarume?
Nzira yakasimba ndeyokuita ejaculate analysis, spermogram. Kugadzirisa chinonzi spermogrammy kuchabvumira kuenzana nehutano hwebonde, kuratidza zvinetso zvinogona kukanganisa kubata pamuviri, nekudziparadza.
Maererano neWIV maitiro, chironga chinonzi spermogram chinofanira kuzadzisa zvinotevera:
- Bhuku reEjaculate: 1.5 ml kana kupfuura.
- Nhamba yose ye spermatozoa mu ejaculate: mamiriyoni makumi mana kana kupfuura.
- Kuwedzera kwepermatozoa mu 1 ml: mamiriyoni 15 kana kupfuura.
- Kushanda kwepermatozoa: 40% kana kupfuura.
- Uhu hune hufambi hunofambira mberi: 32% kana kupfuura.
- Viability ye spermatozoa: inokwanisa 58% kana kupfuura.
- Morphology: maitiro akafanana 4% kana kupfuura.
Nzira yekutora spermogram?
Usati waisa muto pakuongorora, zvakakosha kuti urege kuita zvepabonde kwemazuva masere, asi kwete kupfuura vhiki. Iwe haugoni kunwa doro (kusanganisira doro), mishonga, shanyira sauna, tora bhaji inopisa. Iyo yakawanda inotonhora kuitira kuti chirume hachifi, 20-37 ° C, kuporesa chirwere chiri pasi pe 20 ° C kunotungamirira kune kukanganisa kwezvikamu. Saka, zviri nani kutora kuongorora mune imwe nzvimbo umo laboratori iripo. Zvakakosha kuti mbeu yose yakasimbiswa iyo yave yakasiyiwa muiraira reirabato inowanikwa munzvimbo. Kurasikirwa kwechikamu chimwechete kunogona kukanganisa chigumisiro chekudzidza.
Kana iyo nhamba yepermogram yakakwirira, kumwe kuongorora kunogona kukwana. Asi kana iwe uchitarisa pathologies mu ejaculate, iwe uchada kuongorora maviri kana katatu neyenguva yemazuva manomwe.
Ndinofanira kutora spermogram here?Haasi vanhu vose vanobvumirana kuenda kune chirongwa chepermogram pachikwata chekuita pamuviri. Zvakanaka, izvi zvinonzwisisika uye zvinogona kutongerwa nezvikonzero zvezvakanaka. Zvisinei, mumamiriro ose ezvinhu, murume anofanirwa kufunga nezvekuvandudza kunaka kwehuta uye kuwedzera kufamba kwepermatozoa. Ichokwadi ndechokuti pamusoro pemakore makumi maviri akapfuura, hutano hwemhino hwevarume hwakaderera zvikuru. Izvi zvinokonzerwa nekuti kunyanya, morphology uye, zvinonyanya kukosha, motility yepermatozoa inonyanya kugadzikana kune simba rekunze: kuora kwezvinhu zvakasikwa, kunwa doro uye mamwe mishonga, kusvuta, kusagadzikana, nezvimwewo.
Kuwedzeresa motility ye spermatozoa uye hutano hwemhino huchabatsira mavitamine chaiwo ekugadzirira. Zvakakosha kunzwisisa kuti sezvo kucheneswa kwepermatozoa kunotora mazuva makumi manomwe nemaviri, murume anofanira kupiwa mwedzi mitatu kuti agadzirire pamuviri. Vitamine kuvarume munguva iyi inofanira kutorwa zuva nezuva. "Mavhithamini evanhu" anofanira kunge ane zinc, vitamin E uye L-carnitine mupamusoro dheji. Zvose izvi zvikamu zvikamu zvechirwere "Spematon". "Spematon" inokurudzira spermatogenesis uye inovandudza hutano hwepamusoro nekuda kwekuti:
- L-carnitine inowedzera nhamba ye spermatozoa, inovandudza mararamiro avo, inobatsira kuderedza nhamba ye morphologically isina kukwana masero masero.
- Zinc inokosha pakufananidzira kwehomoni testosterone uye follicle-stimulating hormone (FSH), iyo inofanirwa kubudiswa kwehuta.
- Vitamin E inowedzera kufamba uye kufungidzirwa kwepermatozoa, inowedzera kugona kwayo.
Uye zvechokwadi, zvinofanira kurangarirwa kuti kuronga pamuviri hakurevi mavitamini evanhu chete, asiwo mararamiro ane hutano, kungorega kwenguva pfupi kubva kunwa doro uye kusvuta, kudya kwakakodzera uye mafungiro akanaka. Hungu, kushungurudzika, zvakare, kunowedzera mamiriro ezvinhu emuviri wechirume uye kunokanganisa kunaka kwehuta.
Mwedzi mitatu yekunyatsochenjerera muviri wako uye kuchengeta mitemo iri nyore ndizvo zvinogona kuitwa nomunhu wese kuitira utano hwomwana wake asati aberekwa asati aberekwa.
