Spermatogenesis Description & Process Britannica

WebIn oviparous animals, fertilization takes place internally but embryo development takes place externally. The eggs of birds such as hen and duck carry immature embryo in them. The hard shells of eggs protect them from damage. Once the fetus is matured, the egg hatches. The trait of egg-laying animals is known as oviparity. Sperm production occurs in the testicles. Upon reaching puberty, a man will produce millions of sperm cells every day, each measuring about 0.002 inches (0.05 millimeters) long.
