10 fakta du bør vite om sperms

Spermatozoon (flertall: spermatozoa) med sperm eller full vitenskapelig navn er den reproduktive cellen som tilhører mannlige individer.

Produksjonen av disse cellene i testiklene begynner i puberteten. Det bærer arvelig informasjon (DNA) at det vil overføre til egget under befruktning i hodet delen. Han har en hale og han beveger seg. Hos mennesker er omtrent 150-200 millioner sperms utgitt under en mating. Imidlertid kan bare en sperm celle fertilide egget. Når en sperm når en egg celle (oocyte), etterlater den halen utenfor for å gå inn i egget og passerer arvelig informasjon til eggene. Sperms er funnet i en tett væske. Navnet på denne væsken er sæd (Ersuyu), ejeculate eller ofte brukt i form av Sperma.

Leder av Spermatozois ligner Baker ' s spade og inneholder arvelig informasjon. Det er en struktur kalt Akzoroma som omslutter hodet del som en lue og inneholder enzymer som er nødvendige for spermatozoside å passere gjennom egg celle veggen. Når sperm cellen når egget, blir enzymene i acrosome membranen frigitt, slik at spermatozoa kan inngå egget. N antall mannlige DNA-materialer som kommer i er kombinert med en rekke kvinnelige DNA-materialer og består av 2n antall DNA-materialer (denne cellen kalles zygote). Deretter, i zygote, cellene begynner å multiplisere med å dele. X-og Y-kromosomer som bæres av Spermatozoas i dannelsen av kjønn er avgjørende. Når den kvinnelige reproduktive cellen bærer X kromosomer, halvparten av den mannlige reproduktive celler X og den andre halvparten bære Y-kromosom. Hvis den kvinnelige reproduktive cellen er gjødsle spermatozoon med X-kromosom, blir kromosomer XX og kjønnet til den enkelte blir kvinnelig, mens hvis spermatozoon som bærer Y er gjødsle, kjønnet på den enkelte blir mannlig. Det finnes imidlertid noen unntak. som XXY, X0 kan også forekomme med arvelige syke individer.

Selv om sperm snakkes i den medisinske verden, dens virkninger, fordeler eller innhold er neppe snakkes av mennesker. Men informasjonen om det er svært spennende. Her er 10 interessant informasjon du ikke vet om sperm.
