Kuyaziwa ukuba abachasayo banokuchaphazeleka ngesondo. Zingakhokelela kwiingxaki ngomnqweno, ukuvusa, ukunyuka, kunye ne-orgasm. Ezi ngxaki zesini zihambelana nokusetyenziswa kweeklasi zamachiza ezikhethiweyo-serotonin reuptake inhibitors (SSRIs) kunye ne-serotonin-norepinephrine reuptake inhibitors (SNRI).
Ngokukhawuleza kakhulu ekuphuhlisweni kwe-SSRIs, kwafumanisa ukuba ezi zonyango zingabangela ubunzima nge-ejaculation.
Enyanisweni, la mayeza ayenziwa ngamanye amaxesha amadoda ayenenkathazo ye-ejaculation engaphambi kwexesha ! Kutheni abanokudandathelanisa abanemiphumo enzulu kwimpilo yesondo, ingakumbi kumadoda? Akukho nto enokuyenza ngayo. Kunoko, kuhlobene nendima ye-serotonin kunye namanye ama-neurotransmitter ekuvukeleni nasekukhuleni.
ISerotonin kunye neEjaculation
Isondo, ngeendlela ezininzi, umsebenzi wengqondo. Ukuvuswa komzimba kungenziwa ngokukhuthaza ngokuthe ngqo. Kungenzeka kwakhona ngaphandle kokuvuselela ngqo. Iingcali zezocansi zivame ukucebisa "iingcamango ezingcolileyo" njengongenelelo, kuba ukucinga ngesondo kungaba yinto yokuziphendulela. Njani loo msebenzi? Ngendlela efanayo ukuba iingcinga ezininzi zicutshungulwa-ngokuveliswa kwee-neurotransmitter ezahlukeneyo. Yile ndlela iiseliti ze-nerve zidibana ngayo. Bakhulula baze baphendule kwii-neurotransmitters. Iingcali ze-neurotransmitter ezinjalo ziquka i-serotonin, i-norepinephrine, ne-dopamine.
Ininzi yokuqonda kwethu indima yama-neurotransmitters kunye nezakhi zobuchopho ekuvukeleni nase-orgasm zivela kuphando lwezilwanyana. Nangona kunjalo, kukho uphando lwabantu ngokunjalo. Ngophando, izazinzulu ziye zafunda ukuba kukho imida emininzi yengqondo ehambelana nomsebenzi wesini wesini. Ngokukodwa, indawo yangaphambili ye-hypothalamus ibaluleke kakhulu.
I-MPOA, njengokuba kuthiwa ngamanye amaxesha, apho iifomula zesini ezivela kwiindawo ezahlukeneyo zomzimba ziyahlangana ukuze ziqhutywe. Kwakhona inxalenye yengqondo eqala iintlobo ezininzi zokuphendula ngesondo. Ingqondo ithumela iimpawu phantsi komgca womgogodla obangela ukuba umzimba ube ngowokuqala uvuke kunye ne-orgasm. Icandelo le-amygdala kunye ne-cortex ye-parietali ibalulekile ekulawuleni ukunyuka.
Ama-neurotransmitters yindlela yokwenza le miqondiso. Uphononongo kwiirath uye wabonisa ukuba kunokwenzeka ukwenza ukuba iiphunga zibe yi-orgasm nje ngokusebenza kwezinye i-receptionist ye-neurotransmitter engqondweni. (Iimvume zezi ndawo apho izibophelelo ze-neurotransmitter zibopha. Kukho iintlobo ezininzi zeempendulo ezingaphendula ngamnye, okanye ukudibanisa, ezahlukahlukeneyo.
Kubantu, i-serotonin yi-neurotransmitter ecacileyo ngokucacileyo ehlotshaniswa ne-ejaculation. Umsebenzi we-SSRIs ngokuthintela iiseli ekubuyiseni kwakhona i-serotonin. Oku kuthetha ukuba iimpawu ezibangelwa yi-serotonin zandiswa, zihlala ixesha elide. Ukusetyenziswa okungapheliyo kwe-SSRIs kuye kwaboniswa ukwandisa ixesha phakathi kokulungiswa kunye nokunyuka kwamadoda. Kungenxa yoko kuyimfuneko njengonyango lwe-ejaculation ngaphambi kokuqala.
Kuyathakazelisa ukuba uphando kwizigulisi lubonise ukuba i-serotonin ishintsha utshintsho lwayo. Xa i-serotonin ijojowe kwezinye iindawo zobuchopho be-rat, kubangela ukulibaziseka kwi-ejaculation. Kweminye imicimbi yengqondo, kubangele ukuba kuqhutywe i-ejaculation.
I-Dopamine idlala indima ekwenzeni i-ejaculation, nangona indima yayo ingazange ihlolwe ngokucacileyo njengeyoyi-serotonin. Uphononongo kwizigulane lubonisa ukuba ukuvuselela i-dopamine kunokubangela ukuba kuqhutywe i-ejaculation. Kubantu, kukho uphando lokuxhasa oku. I-Schizophrenics ephathwa ngezilwanyana ezinxamnye ne-psychotic ezithintela uhlobo oluthile lwe-dopamine receptor (i-D2-like receptors) ziyakufumana kunzima, okanye akunakwenzeka, ukuba i-ejaculate.
Ezi ziyobisi ziye zavavanywa kumadoda angama-ejaculation angaphambi kwexesha. Efana ne-SSRIs, kubonakala ngathi yandisa ixesha phakathi kokuvusa nokunyuka. Ukongezelela, kukho ixabiso elincinane lwedatha ebonisa ukuba utshintsho kwi-dopamine receptors lunokwenza ukuba amadoda athile angene ejaculation ngaphambi kokuqala.
Ukuqonda ukuhlaselwa
Ukunyuka kwegazi kuchazwa njengento eqhubekileyo yokuqhubela isisu evela emzimbeni. Iyenzeka kwiindawo ezimbini. Isigaba sokuqala sisiphumo. Yilapho iinqununu ezahlukeneyo zesilwane, kuquka u-sperm, zifihliwe kwiintlobo ezahlukeneyo kunye namalungu. Isigaba sesibini ukuxoshwa. Ngaloo ndlela ukuphambana okukhulu kweemisipha kwisigcawu somzimba kubangela ukuba inambuzane ikhutshwe ngaphandle kwepenisi.
Inqaku, amadoda athile ayenayo iindidi ze-prostate ukuhlinzwa ngeso lengqondo unokufumana "omile". Oku kungenxa yokuba imizimba yabo ayisaphinda ivelise izicwangciso zamanzi. Phantse enye yesithathu yomkhuhlane wamanzi uvela kwi-prostate. Ezinye izilonda ezifaka isandla ekuveliseni imveliso yamanzi ziyakwazi ukuchaphazeleka ngophando lomhlaza.
Kwindoda, igama elithi orgasm lisetyenziswe ngokufana nesigama sesigxina sokuthi u-ejaculation. Nangona kunjalo, ukunyuka kwe-ejaculation kunye ne-orgasm akuyona into efanayo. Nangona kukho ininzi yamadoda, i-orgasm iyenzeka ngokuyinhloko ngexesha lokunyuka, akusoloko kunjalo. Amanye amadoda aninzi-orgasmic angaba ne-orgasms ezininzi nge-ejaculation eyodwa kuphela. Amanye amadoda akakwazi ukuhlambalaza. Le meko yaziwa ngokuba yinto engenayo.
UkuKhutshwa koKwahlula kunye nokuHlanywa
Kubalulekile ukuba uqaphele ukuba ukulungiswa akudingeki ukuba u-ejaculation kwenzeke. Ukuhlaselwa ngaphandle kokulungiswa akuqhelekanga, kodwa kunokwenzeka. Umzekelo oqhelekileyo wolu hlobo uqhutyelwa kumakhwenkwe asetsheni ngelixa belele-okubizwa ngokuba "ukuphuma kwelanga" okanye "amaphupho amanzi." Ukukhutshwa komhla wobusuku kungenziwa kunye okanye ngaphandle kobukhoko. Ukunyuka ngaphandle kokumiswa kungaphinda kuvuselelwe ngokusebenzisa ukutshatyalaliswa kwendoda kumadoda aneentlobo ezithile zokulimala kwentambo yomgogodla. Ngamanye amaxesha le ndlela isetyenziselwa ukuqokelela isityalo ukuze incedise inkqubo yokuzalisa.
Akumangalisi, iinjongo zeengqondo kunye nezinye iindlela zokuphila ezikhokelela ekusungulweni nasekuhambiseni idijithi zihlobene, kodwa azinjalo. Yingakho ii-inhibitors ze-PDE-5 ezisetyenziselwa ukunceda amadoda ane-erectile disysction ayinayo impembelelo enkulu ekusebenzeni kwabo. Zichaphazela ukuhamba kwegazi ngaphakathi nangaphandle kwepenisi. Awuyi kususa ukukhutshwa kweengxenye zesambulo okanye izicatshulwa zomzimba zokuxoshwa.
