Where do sperm fully mature

In the male reproductive system, the scrotum houses the testicles or testes, providing passage for blood vessels, nerves, and muscles related to testicular function. The entire male reproductive system is dependent on hormones, which are chemicals that stimulate or regulate the activity of cells or organs. The muscle provides much of the force needed for ejaculation to occur. Mature sperm are better able to move, find an egg and penetrate it to complete fertilization. Now, preparing for the procedure, the doctor is alert.

Research shows that increasing age is associated with decreasing sperm quality. The main job of the sperm is to get the haploid genome into the ovum, which will provide the other half of the genome along with pretty much all of the cytosol, cell membrane, and cellular organelles. The presence of this gene in sea anemones —very primitive life-forms—suggests that the ability to produce sperm evolved only once, roughly million years ago. Males can produce several million sperm per day, so the process must be highly regulated by the body in order to ensure sufficient sperm quality and quantity. The surgeon may make a slit in this long, flexible tube and draw out fluid with a needle aspiration or flush the tube with a solution irrigation.

Gametes such as ova, sperm, and pollen begin as germ cells, which, like other types of cells, have two copies of each gene in their nuclei.
