By Dr Ananya Mandal, MD. Sperm is the male reproductive cell in vertebrates. The term is derived from the Greek word sperma meaning seed. Sperm were first observed under a microscope in 1677 by Antonie van Leeuwenhoek who described them as little animals or animalcules.here is little cytoplasm in sperm and the head is densely packed with DNA. Sperm is released from the male in a fluid called semen. Semen is alkaline and does not allow the sperm to be completely motile until they reach the female reproductive tract or the vagina which is acidic in pH.
