Produzione delle cellule sessuali
Every normal mature man and woman produce a sec cell. The male sec cells are called sperms (spermatozoa). They are produced in the testis. They pass through the sperm ducts (vas deferens). They are passed out through the penis. The female sex cell is called ovum or egg. It is produced by the ovary. There are two ovaries in a woman.
Processo di ovulazione e fertilizzazione
Each ovary produces an ovum every month. The prices of producing an ovum by the ovary is called ovulation. If there is a sexual relationship or intercourse between a man and a woman at the period when the ovum is produced, the sperm will fertilize the ovum.
The result is pregnancy. If there is no sexual relationship, the released ovum will die off in a day or two. Then menstruation will occur. Menstruation is the flow of blood which each normal woman of child-bearing age experiences every month, unless she is pregnant.

Domande da interrogazione
- Qual è il processo di produzione delle cellule sessuali negli uomini e nelle donne?
- Cosa accade durante il processo di ovulazione e fertilizzazione?
- Quali sono i segni comuni della gravidanza?
Negli uomini, le cellule sessuali chiamate spermatozoi sono prodotte nei testicoli e passano attraverso i dotti spermatici per essere espulse attraverso il pene. Nelle donne, la cellula sessuale chiamata ovulo è prodotta dalle ovaie, di cui ci sono due in una donna.
Durante l'ovulazione, ogni ovaio produce un ovulo ogni mese. Se avviene un rapporto sessuale durante questo periodo, lo spermatozoo può fertilizzare l'ovulo, portando alla gravidanza. Se non c'è rapporto sessuale, l'ovulo rilasciato muore entro uno o due giorni, e si verifica la mestruazione.
I segni comuni della gravidanza includono l'interruzione delle mestruazioni, seni più pieni e sensibili, nausea e vomito (soprattutto al mattino), minzione frequente, ingrossamento dell'addome a partire da circa 3 mesi, e movimenti del bambino percepiti dalla madre man mano che la gravidanza avanza.
