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.
