![]() Research suggests the testicle size has no bearing on how many sperm the male produces each day. The testicles produce millions of sperm each day, but this number can vary greatly. Sperm motility refers to the ability of sperm to move towards an egg. Sperm count refers to the number of sperm cells present in male ejaculate. Two key factors that can affect male fertility are sperm count and sperm motility. The tail propels the sperm forward, towards an egg for fertilization. The purpose of the sperm tail, or flagellum, is to allow movement. These specialized structures provide the energy necessary for the sperm cell to move. The midsection of the sperm contains energy producing mitochondria. The acrosome contains proteins that help the sperm penetrate the outer shell of an egg. When the sperm and egg combine, this results in an embryo with 46 chromosomes.Ĭovering the head of the sperm is a cap that doctors call an acrosome. Typically, both the human sperm cell and the human egg cell each contain 23 chromosomes. The sperm head contains chromatin, which is the DNA material that makes up chromosomes. When studying a sperm cell under a microscope, scientists can typically identify the following three parts: The head When a sperm combines with a female gamete, or egg, it results in a human embryo. The term “gamete” implies that the cell is half of a whole. Sperm is the male reproductive cell or gamete. doi:10.1016/j.fertnstert.2014.10.Share on Pinterest A doctor may suggest a semen analysis to a person struggling to conceive with their partner.
