Spermatogenesis vs. Oogenesis


Which of the following statements is TRUE as it relates to spermatogenesis and oogenesis in humans?


Spermatogenesis is asymmetrical,​ while oogenesis is symmetrical.


Spermatogenesis ultimately results in one functional sperm cell with three polar bodies that disintegrate as a result of each meiotic division. Oogenesis creates four functional egg cells per meiotic division.


Spermatogenesis is a rapid, uninterrupted cycle of meiosis. Oogenesis can begin but be interrupted at various points during meiotic division, sometimes for long periods of time.


Spermatogenesis only occurs during a limited time within a human male's lifetime, and the male is born with a finite number of sperm cells. Human females, in contrast, produce oocytes throughout their lifetimes.
