10 fatti che dovresti sapere sugli spermi

Spermatozoi (plurale: spermatozoi) con sperma o nome scientifico completo è la cellula riproduttiva appartenente a individui maschi.

La produzione di queste cellule nei testicoli inizia durante la pubertà. Trasporta informazioni ereditarie (DNA) che trasferirà all'uovo durante la fecondazione nella sezione della testa. Ha una coda e si muove. Nell'uomo, circa 150-200 milioni di spermatomeri vengono rilasciati durante un accoppiamento. Tuttavia, solo una cellula dello sperma può fertilare l'uovo. Quando uno sperma raggiunge una cellula uovo (oocyte), lascia la coda all'esterno per entrare nell'uovo e passa le informazioni ereditarie alle uova. Gli spermi si trovano in un liquido denso. Il nome di questo liquido è lo sperma (Ersuyu), ejeculate o comunemente usati sotto forma di sperma.

La testa degli spermatozoi assomiglia alla pala del fornaio e contiene informazioni ereditarie. C'è una struttura chiamata Akzoroma che avvolge la parte della testa come un tappo e contiene gli enzimi necessari per lo spermatozoside di passare attraverso la parete delle cellule uovo. Quando la cellula dello sperma raggiunge l'uovo, gli enzimi nella membrana acrosome vengono rilasciati, permettendo agli spermatozoi di entrare nell'uovo. Il numero n di materiali di DNA maschili che entrano sono combinati con un numero di materiali di DNA femminile e consistono di 2n numeri di materiali del DNA (questa cellula è chiamata Zygote). Poi, nello zigote, le cellule iniziano a moltiplicarsi dividendo. I cromosomi X e Y che sono trasportati dagli spermatozoi nella formazione del genere sono decisivi. Quando la cellula riproduttiva femminile trasporta cromosomi X, metà delle cellule riproduttive maschili X e l'altra metà trasportano il cromosoma Y. Se la cellula riproduttiva femminile fertilizza lo spermatozoo con il cromosoma X, i cromosomi diventano XX e il sesso dell'individuo diventa femminile, mentre se lo spermatozoo che trasporta la Y è fertilizzare, il sesso dell'individuo diventa maschio. Tuttavia, ci sono alcune eccezioni. come XXY, x0 può verificarsi anche con individui malati ereditari.

Anche se lo sperma è parlato nel mondo medico, i suoi effetti, benefici o contenuti sono difficilmente parlati dagli esseri umani. Ma le informazioni su di esso è molto intrigante. Ecco 10 informazioni interessanti che non conosci sullo sperma.
