What are the main differences in the formation of the egg and sperm in males and females?
What will be an ideal response?
Sperm formation, or spermatogenesis, in males occurs in the seminiferous tubules, which involves the development of four sperm cells from each spermatogonium. A mature male produces millions of sperm. In contrast, a mature female usually produces only one egg (technically a secondary oocyte) each month. Also, oogenesis begins during fetal development, but egg development is arrested and won't continue until ovulation and fertilization take place. In oogenesis, there will be only one viable egg produced and three polar bodies.
