Process of maturation and development of sperm is called
a)	Oogenesis	b)	Spermatogenesis	c)	Spermiogenesis	d)	None of these

Spermatogenesis is the process of the formation of haploid spermatozoa (sperms) from the undifferentiated diploid primordial germs cells of the testes, which involves multiplication phase, growth phase, maturation phase and differentiation phase, whereas  Spermiogenesis is the process to transformation of spermatids intospermatozoa (sperms) which involves differentiation phase.
