Kusanthula umuna

Anthu okwatirana amene sangathe kukhala ndi mwana kwa nthawi yaitali amayang'ana chifukwa chomwe nthawi zambiri amachitira mkazi. Mawu akuti "kusabereka kwa amayi" tsopano ali pamilomo ya ambiri, ndipo ndizovuta kwambiri kulankhula za kusabereka kwa amuna. Koma ntchito yabwino ya uhule wamwamuna imakhudza 50 peresenti ya kupambana kwa mimba ya mwanayo. Pofuna kudziwa momwe munthu alili ndi pakati, ndikofunika kuti awonetsetse kuti amatha kuganiza za umuna kapena spermogram. Kufufuza kwa umuna kungapangidwe mu ma laboratories ofunikira kubereka ndi zipatala zapadera.

Umuna ndi mimba

Spermatozoa wamwamuna ndi gawo lofunika kwambiri kuti ayambe kutenga mimba. Nkhumba za pathupi zimakhala ndi nthenda yaikulu, yogwira ntchito ya spermatozoa, lethargic ndi immobile spermatozoa idzafa musanafike ku ovum. Pakati pa kugonana, pafupifupi milioni 200 spermatozoa imalowa mumaliseche, onse amawunikira dzira, koma mbali yochepa chabe - yomwe imakhala yolimba kwambiri komanso yolimba kwambiri - imalowa mkati mwa iyo yokha. Ndipo kotero, pamene kusanganikirana kwa mtima wawo kunachitika, ndiye dzira limakhala losalephereka kwa otsala a spermatozoa ndikuyamba kugawa. Panthawiyi, ntchito ya munthu imayesedwa, ndipo mwayi wokhala ndi mimba, kupitiriza kwake ndi kutha nthawi yabwino kumadalira thupi la mkazi.

Kodi mungapereke bwanji chiyeso kwa umuna?

Kupereka kwa umuna kumapangidwe kumachitika zambiri:

• kupeŵa kugonana mkati mwa masiku 3-4 chisanachitike;
• m'masiku akudziletsa ku kugonana, kukana kumwa mowa, fodya, sauna, kusamba ndi mankhwala.

Amuna ambiri amakhala ndi chidwi ndi momwe amachitira umuna kuti awunike. Ikhoza kuperekedwa, pogwiritsa ntchito maliseche kapena kusokoneza kugonana. Kugwiritsira ntchito kondomu sikofunika kwambiri, chifukwa mukakambirana ndi mphira pambuyo pa mphindi 15-20, spermatozoa imasiya kutuluka kwawo.

Kutenga nyemba kuti iwonetsere kuyenera kuchitika pamalo ogwiritsa ntchito ma laboratory komwe idzafufuzidwa, popeza kusinthasintha kwa kutentha kwake kumakhala pansi pa 20 ° C ndipo pamwamba pa 37 ° C kumapangitsa kusintha kwa malo ake ndi kutanthauzira kosayenera kwa kulingalira kwa umuna. Ndikofunikira kwambiri kuti lonse lonse la umuna umene umataya panthawi yopuma umalowa mu chubu. Izi zimakhudzanso kulondola kwa zotsatira.

Kusanthula kamuna kafukufuku

Pofufuza kafukufuku wa umuna, kuchuluka kwake, khalidwe labwino komanso khalidwe lachikhalidwe kumayesedwa. Tiyeni tiwone momwe kusanthula kwawonetsera za umuna kuli koyenera.

Mlingo wa ejaculate uyenera kukhala oposa 2 ml, kusasinthasintha kwabwino. Kawirikawiri, umuna uyenera kusokoneza pambuyo pa 10-30 mphindi, ukhale ndi masentimita awiri, masentimita oyera, imoto yosavuta, ndi mafuta a pH a 7.2-8.0, ukhale mdima, ulibe thunzi. Chiwerengero cha spermatozoa mu njira yoyenera mu 1 ml. - 20-200 miliyoni. Chiwerengero cha spermatozoa - choposa 25% cha chiwerengerocho, chonsecho chilibe mphamvu kuposa 50%, ndipo chimakhala chosapitirira 50%. Spermatozoa sayenera kugwirana pamodzi ndikukhazikika. Chiwerengero cha leukocyte mu ejaculate sayenera kupitirira 1 million, ndipo chiwerengero cha spermatozoa choyenera chiyenera kukhala oposa 50%. Makhalidwe apamwamba a pamutu ayenera kukhala oposa 30% a spermatozoa, komanso maselo 2-4 a spermatogenesis. Kufufuza kafukufuku wa umuna kungakhale kuchokera ku gawo limodzi la ejaculate.

Ndikofunika kudziŵa kuti potency yabwino yamunthu sinali chizindikiro cha umoyo wake wa umuna. Nthawi zina amuna omwe ali ndi ubwino wokhala ndi umuna amakhala ndi ubweya wambiri, ndipo mofananamo, amuna omwe ali ndi mavuto amatha kukhala ndi ubwino wabwino wa umuna. Kudziwa zinthu izi ndi banja lopanda banga liyenera kutsogoleredwa ndi odwala awiriwo.
