Spermatogenesis is the process of functional sperm/spermatozoa from diploid spermatogonia. Its formation is under the control of FSH and androgens. The different steps involved in spermatogenesis are the multiplicative phase, growth phase, maturation phase, and differentiation. The sperm consists of a head, neck, middle piece, and tail. So take this quiz and increase your knowledge about spermatogenesis.
