10 fapte ar trebui să știți despre sperme
Spermatozoizii (plural: spermatozoizi) cu spermă sau Denumire științifică completă este celula reproductivă aparținând persoanelor de sex masculin.
Producția acestor celule în testicule începe în timpul pubertății. Acesta transportă informații ereditare (ADN), care se va transfera la ou în timpul fertilizării în secțiunea cap. Are coadă și se mișcă. La om, aproximativ 150-200 milioane de spermatozoizi sunt eliberate în timpul unei împerecheri. Cu toate acestea, doar o singură celulă de spermă poate fertilide ou. Atunci când un spermatozoid ajunge la o celulă de ou (oocyte), lasă coada afară pentru a intra în ou și trece informațiile ereditare la ouă. Spermatozoizi se găsesc într-un lichid dens. Numele acestui lichid este material seminal (ersuyu), ejaculare sau utilizate în mod obișnuit sub formă de sperma.
Capul Spermatozopetilor seamănă cu lopata brutarului și conține informații ereditare. Există o structură numită Akzoroma care împachetează partea capului ca un capac și conține enzimele necesare pentru ca spermatozoziul să treacă prin peretele celulei de ou. Când celula de spermă ajunge la ou, enzimele din membrana acrosome sunt eliberate, permițând spermatozoizilor să intre în ou. Numărul n de materiale ADN masculine care vin în sunt combinate cu un număr de materiale de ADN feminin și constau din numărul 2n de materiale ADN (această celulă se numește zygote). Apoi, în zygote, celulele încep să se multiplice prin împărțirea. Cromozomii X și Y care sunt transporți de Spermatozoli în formarea de gen sunt determinați. Când celula reproductivă feminină poartă cromozomi X, jumătate din celulele de reproducere masculine X și cealaltă jumătate transportă cromozom Y. În cazul în care celula reproductivă feminină fertilizează spermatozoizele cu cromozom X, cromozomii devin XX, iar sexul individului devine feminin, în timp ce în cazul în care spermatozoizul care transportă Y este fertilizat, sexul individului devine mascul. Cu toate acestea, există unele excepții. ar fi XXY, x 0 pot apărea, de asemenea, cu persoane bolnave ereditare.
Deși sperma este vorbită în lumea medicală, efectele sale, beneficiile sau conținutul sunt greu de vorbit de oameni. Dar informația despre asta e foarte interesantă. Aici sunt 10 informații interesante nu știți despre spermă.
- Sperma este produsă în testiculele bărbaților și este necesară timp de 10 săptămâni pentru fiecare spermă la riper.
- Sperme mature pot aștepta 2 săptămâni pentru "ziua cea mare". Până atunci, ei stau în episodul numit Epididmis.
- În cazul în care sperma nu este excretat cu ejaculare este rupt și absorbit de organism.
- Doar 10% din spermă conține spermă. Restul contine enzime, vitamina C, calciu, proteine, sodiu, zinc, acid citric, zahar de fructoza. Toate aceste componente sunt lucruri care ajută sperma să supraviețuiască.
- Barbatii sanatosi produc 70-150 milioane de spermatozoizi pe zi, dar pot pierde pana la trei ori mai mult decat ejacit.
- Un mascul mediu poate descărca până la o jumătate de linguriță.
- În timp ce bărbații produc milioane de spermă nouă în fiecare zi, maturizarea lor poate dura o medie de 2-3 luni.
- Majoritatea spermelor pot trăi aproximativ 72 ore în corpul feminin. Cu toate acestea, în condițiile potrivite, acesta poate rămâne în viață între 5 și 7 zile.
- Există spermă anormală, și ar putea fi o chestie cu două capete, cu coadă scurtă, cu cap mic, cu capul mare.
- Sperma are, de asemenea, sex. Sperma feminină este mai lentă, dar mai puternică, în timp ce sperma masculină este mai rapidă, dar mai slabă.
