Ziziphi iindidi ze-spermatozoa ezahlukileyo?
Kuhlalutyo lwe-motility ye-spermatozoa, kungekhona nje isantya sokunyakaza, kodwa kwakhona ukulandelwa kokuhamba kweeseli zesini kuhlolwa. Ngokuqhelekileyo, ngokwemiqathango yesifundo, yonke i-spermatozoa ihlukaniswe ngamaqela amane:
- iisini zesini kunye nokuhamba okukhawulezayo, okuqhubekayo;
- b - inkqubela eqhubekayo yokuhamba ngokukhawuleza;
- c - akukho ntshukumo yokuqhubela phambili okanye i-spermatozoa ishukunyiswa endaweni enye, isuka ukusuka ecaleni ukuya ecaleni;
- d - iseli zesini asinakususwa.
Ngokuxhomekeke kumlinganiselo walezi zigaba kwaye uhlole i-ejaculate yesintu yokuzala.
Okwangoku, entshonalanga, kukho inkqubo eyahlukileyo yokuvavanya iseli zesini zesini ukuhamba. Ngoko, ngokuqhelekileyo iingcali zangezizwe zinika iindidi ezi-3 zesini zesini xa zihlola ukuhamba kwazo:
- I-progressive-mobile (PR) - iisetyini zesini zesini ezihamba ngokukhawuleza ngokwasemzimbeni okanye kwisangqa nge-radius enkulu. Ngokoluhlu olukhankanywe ngasentla, ezi ziiseli zecandelo kwaye b;
- engekho inqubela-yeselula (i-NP) - i-spermatozoa enohambo lokungahambisani nalokhu ngasentla, kungekho nkqubela (icandelo c);
- (IM) - ukungabi naluphi na ukunyakaza.
Ixabiso elikhawulezileyo lokuchumisa ngokuphumelelayo yinkalo ye-spermatozoa PR okanye i-b b kwenye indawo.
Ziziphi iiparitha zokuhamba kwezidumi zentsholongwane zihambelana nokuqhelekileyo?
Nangona kunjalo, ukuba ukuchumisa ngempumelelo, i-morphology yeeseli zentsholongwane ibaluleke ngaphezu kokuhamba kwazo, iparameter yokugqibela kufuneka ifakwe ingqalelo xa iqhuba amanyathelo okwelashwa kwindoda engapheliyo.
Ngokwemigangatho yonyango, xa uvavanyo lwesidoda, iseli leselula yeselula kufuneka libe ubuncinane kwi-35% yenani le-spermatozoa kwisampuli. Yilesi sibonakaliso sokuba iingcali zihambelana nazo xa zivavanya umgangatho wesilisa wesilisa.
Yintoni eyenza ukuhamba kwe-spermatozoa?
Kubalulekile ukuba uqaphele ukuba le parameter yamaseli ezithando zesilisa ifuthe kakhulu kwizinto zangaphandle. Yingakho kubesilisa ngokumalunga nobudala obufanayo, eli lathisi lingahluka.
Ukuba sithetha ngokuthe ngqo malunga nento echaphazela ukuhamba kwe-spermatozoa, ngoko kufuneka sichaze ezi zinto zilandelayo:
- imikhwa emibi (iicicin, utywala);
- ukuhamba rhoqo kumaqondo aphezulu aphezulu (sebenzela kwisitolo esishisayo, umzekelo);
- ubukho beentlobano zesini kunye nesifo esingapheliyo sokuvuvukala kwindlela yokuzala yabantu;
- mpe mbelelo engqongileyo yemeko.
Indlela yokwandisa umlingo wesilisa?
Kwakhona, ukwandisa ukuhamba kwe-spermatozoa, izidakamizwa zinokumiselwa. Phakathi kwabo nguSpemann, Proviron, Andriol, Pregnil. Ubude bexesha lokumkelwa, ukuphindaphindwa kunye nokulinganisa kuboniswa kuphela ngugqirha.
Ngaloo ndlela, sinokuthi isisombululo kule ngxaki siquka indlela ehlangeneyo kunye nokujonga rhoqo ngamayeza.
