Vakasvuta Vane Chisikwa Chepasi Chese Sperm Count
Kuwanda kwebambani kunoshandisa pakati pevarume vezera rekubereka hakuna kumbobvira rakakwirira, nepo varume vanokonzera kuberekwa kunewo kuwedzera. Vanotsvakurudza vanotenda kuti kupararira kwemutemo wezvokurapa uye zvekudya kunoshandiswa muUnited States kunogona kuva chinhu chinokonzera kuwedzera kwekusagadzikana kwevarume.
Ongororo dzinoverengeka dzakabatanidza kushandiswa kwepambani uye kusagadzikana kwevarume asi kushandiswa kwemishonga kunobata kusagadzirisa kwakave kwakabatanidzwa kune zvikonzero zvakasiyana-siyana.
Chimwe chidzidzo chakawana kuti varume vanosvuta mbanje kazhinji vane zvishoma zvakanyanya seminal fluid, aine mbeu shoma pasi uye mbeu yavo inoita zvisina kufanira. Zvose izvi zvinogona kukuvadza kubereka.
Yunivhesiti kuBuffalo yekudzidza ndiyo yekutanga yekuongorora marijuju yemigumisiro pamusoro pemaitiro chaiwo okushambira emadhimoni kubva kune vanoputa marijuji uye kuenzanisa nemigumisiro nehuta hwevarume hunosimbisa kubereka. Marijuana ine mishonga inonzi cannabinoid THC (tetrahydrocannabinol), iyo inonyanya kushandiswa mumakemikari yemakemikari, pamwe nezvimwe zvinogona kushandiswa.
Mbeu Inoshambira Izvo Zvokurumidza, Zvokutanga Pakutanga
"Chinonyanya kukosha ndechokuti, izvo zvinoshandiswa pakugadzira mbanje zviri kuita chimwe chinhu kumunhu, uye nhamba dziri munzira yekusava nekushaya simba," akadaro Lani J. Burkman, Ph.D., munyori anotungamirira pachidzidzo.
"Hatizivi chaizvoizvo zviri kuitika kuti tishandise hutano hwemhumhi," akadaro Burkman, "asi isu tinofunga kuti ndeimwe yezvinhu zviviri: THC inogona kunge ichikonzera nguva isina kunaka yehurosi kuburikidza nekukurudzira zvakananga, kana inogona kunge ichideredza kuvhara kwepanyama nzira.
Pasinei nokuti chii chinokonzera, chirume chacho chiri kushambira nokukurumidza zvikuru kare. "
Kuchinja muSermerm Enzyme Cap
Iyi nzira inoshandiswa yakave yakabatanidzwa mukusafa mune zvimwe zvidzidzo, akadaro.
Bhuku reBuffalo rakawanikwawo mu laboratori ye andrology yakaratidza kuti hupenyu hwevanhu hunoonekwa pachena kuhupamhi hweHTC hwakaratidza kusagadzikana kusina kushandiswa muhupenyu hwemadziro enzyme, inonzi acrosome.
Apo vatsvakurudzi vakaedzwa maitiro anandamide zvakaenzana - inokosha yemafuta anonzi neurotransmitter - pamunhu wevanhu, maitiro ezvakanaka ekushambira akachinjwa uye mbeu yakaratidza kuti yakagadziridzwa kukwanisa kubatanidza neiyo isati yasvika.
Kuedzwa kweSperm Count
Burkman uye vashandi pamwe chete vakagamuchira mvura yemasitini kubva kumakumi maviri nemakumi maviri nematanhatu akachengetedza mbanje vachiputa uye vakaisa sampuli kune miedzo yakasiyana-siyana. Vaya vanozvipira vakataura kusvuta mbanje kanenge ka 14 pavhiki, uye kwemavhareji emakore 5.1.
Kudzora nhamba kwakawanikwa kubva kune varume makumi mashanu vanobereka vakabereka pamuviri. Vanhu vose vakaramba kuita zvepabonde kwemazuva maviri vasati vaongorora kubhi.
Kubva kumapoka ose maviri, sampuli dzakaongororwa nehuwandu, huwandu-count-per-unit of seminal fluid, total sperm count, chikamu chemuviri chakanga chiri kufamba, velocity uye chirume chemuviri.
Marijuana Vakasvuta Vakanga Vashoma Kupfura
Zvigumisiro zvakaratidza kuti zvose zviri zviviri zvemumonta yemvura uye nhamba yose yehuta kubva kune vachiputa marijuji yakanga isingasviki kune yekubata ushe kwevarume. Zvimwe zvinopesana zvakaonekwa zvakare apo hyaluronic acid (anionic, nonsulfated glycosaminoglycan yakaparadzirwa zvikuru mukati rose, epithelial, uye neural tissues) uye kufema, zvose zvisati zvaitika uye shure kwekushamba, zvakaongororwa, chidzidzo chakawanikwa.
"Mbeu inobva kuvhujwa inopfungaira yakanga ichifamba nokukurumidza zvikuru," akadaro Burkman. "Nguva yacho yakanga isiri iyo.Uyu hurau huchava nehutano husati hwasvika mazai uye husingazokwanisi kubereka."
Dambudziko rekuberekwa kwepamusoro pevarume varume
Vatsvakurudzi vakabvuma kuti varume vakawanda vanosvuta mbanje vave nevana. "Varume avo vanonyanya kuchinjwa vanogona kunge vachiita zvigaro zvekurima, uye THC kubva mumuchomo inogona kuvamanikidza kusvika pamucheto kusvika pakushaya simba," akadaro.
Nezvemubvunzo wekuti inogona kubereka inogona kudzoka kana vanotsvaga vakamira kushandura mbanje: Burkman vakati nyaya yacho haina kuongororwa zvakanaka zvakakwana kuti ipe mhinduro yakananga.
"THC inoramba yakachengetwa mumafuta kwenguva yakareba, saka iyo inogona kunge yakanyanyisa." Hatigoni kutaura kuti zvinhu zvose zvichadzokera kumashure. vari panjodzi.ndiri kunyatsokurudzira chero munhu ari kuedza kubata kuti asasvuta mbanje, uye izvozvo zvinosanganisira vakadzi pamwe nevarume. "
Kuyambuka zviratidzo zveFertili
Kutsvakurudza kwakazotevera naBurkman neshamwari vakawana kuti mari inoshandiswa inogona kukanganisa maitiro emakemikari ekufananidzira kunoitika panguva yekudyara. Marijuana inoshandiswa inogona kukanganisa arachidonylethanolamide (AEA) inowanikwa mumvura yepasema yemunhu, pakati pemiganhu ye oviductal fluid, uye follicular fluid.
Mbeu inoratidzirwa kune iyi inonaya mvura inobereka pavanenge vachibva kubva kumadzimai kusvika kunzvimbo yekumera mu oviduct. Vatsvakurudzi vakaona kuti AEA-chiratidzo chinogona kutonga chirume chinoshandiswa pakudyara mumaturakiti evanhu ekubereka, uye kuti kusvuta mbanje kungakanganisa izvi.
Kuvhiringidza Sperm Mabasa
Zvimwe zvidzidzo zvakawana kuti mbanje inoshandisa zvinogona kuvhiringidza endocannabinoid system (ECS), iyo inobatanidzwa mukugadzirisa kwekusununguka kwevarume. Zvimwe zvakasiyana-siyana mu vivo uye in vitro zvidzidzo zvakawanikwa kuti marijuana inoparadza hypothalamus-pituitary-gonadal axis, spermatogenesis, nemabasa akasiyana-siyana evanhu.
Imwe yedzidzo ye endocannabinoid system yakawana kuti marijuana inogona kudzivisa basa rekucherechedza kwe FAAH (mafuta asidi amide hydrolase) iyo yavakawana ine basa rinokosha mukati mezviratidzo zvekubereka, izvo zvinoita basa mukudzora matanho anoverengeka eboka revanhu.
Zviri pachena kubva kune idzi dzakasiyana-siyana zvesayenzi iyo mbanje inoshandisa inogona kuita mabasa akasiyana-siyana mukuzvara kwemurume uye hapana mumwe wavo anovandudza kubereka.
