Play Elemental Can you conquer the elements? Analyzing Scientific Data in In human males, by contrast, meiosis and spermatogenesis do not begin in the testes until puberty and then go on continuously in the epithelial lining of very long, tightly coiled tubes, called seminiferous tubules. Spermatogonia develop from primordial germ cells that migrate into the testis early in embryogenesis. Sperm Are Produced Continuously in Most Mammals In mammals, there are major differences in the way in which eggs are produced oogenesis and the way in which sperm are produced spermatogenesis. In this lesson, you will learn the definition of a sperm cell, as well as its primary function.

The gametophytes of bryophytes , ferns and some gymnosperms produce motile sperm cells, contrary to pollen grains employed in most gymnosperms and all angiosperms. Sperm cells were first observed by Anton van Leeuwenhoek in Related to sperm quality is sperm size, at least in some animals. When an egg and a spermatozoon unite, they create a zygote, which will develop into an embryo an unborn, developing organism , and later into a fetus. When the sperm passes through the cervix, it smells the female ova from the egg.
What are sperm cells?
Description: On the other hands, while spermatozoa are one of the smallest cells in the male body, ova are one of the largest cells present in the body of human females. Learning Outcome When you are done watching and reviewing this lesson, ensure that you can accurately describe the structure and function of a sperm cell. They occur in the structure of the sperm cell and can lead to male infertility , thereby preventing fertilization from taking place. Pages Images and files Insert a link to a new page Loading
