What is the difference between egg and sperm formation

Ovum is called oosphere in algae. Ovum has a cell substance at its center called the yolk or ooplasm. Ooplasm contains a nucleus named the germinal vesicle and also nucleolus called the germinal spot. Ooplasm has formative yolk and nutritive yolk, the formative yolk is the cytoplasm of an ordinary animal cell and the nutritive yolk deutoplasm is made of rounded granules composed of fatty and albuminoidal substances in the cytoplasm. The latter helps in nourishing the embryo in the early stages of developmental phase in mammals.

On the other hand, birds contain egg nutritive yolk which is enough to supply its chick enough nutrients throughout the period of incubation. We will highlight the differences between sperm and ovum in a tabular chart as follows. It is the male gamete or male reproductive cell. It is a female gamete or female reproductive cell. It is a motile cell having flagella that helps in its movement and penetration into ovum.

Size of cell. It is the smallest cell in the human body. It is one of the largest cells in the human body. Location of mitochondria. Mitochondria is centrally located in this cell. Mitochondria is scattered in the cytoplasm of the cell. Amount of Cytoplasm. Cytoplasm is present in very small amounts in sperm cells. Cytoplasm is present in large amounts in the egg cell or the ovum. Nucleoplasm is absent in the cell. Nucleoplasm or the germinal vesicle is present in the egg cell.

Type of Chromosomes. They use their tails to swim against the stream of fluid in the oviduct to the fallopian tube.

Difference between Egg Cells and Sperm Cells. Egg Cells Sperm Cells Anatomy The egg cells have a nucleus that is surrounded by cytoplasm, which is guarded by the zona pellucid and the follicular cells.

Produced in Egg cells are produced in the ovary of a female human being. Sperm cells are produced in the testicles of a male human being. Size Larger compared to sperm cells. Approximately 0. Appearance The egg cell is one of the largest human cells in the body.

Shape Round, oval or a circle. Produce in numbers Only a single egg cell is produced during once menstruation cycle. Millions of cells are released during a single ejaculation. Temperature Requires warm body temperature for sustenance. Requires approximately two degrees lesser than the body temperature for sustenance. Time of formation Egg cells are usually formed in a female before birth. Sperm cells form during puberty. Life-span Egg cells have a short life span.

Production till Egg cells form before birth and are active only till menopause. Sperm cells start being produced from the body from puberty till death.

Storability Cannot be stored. Can be frozen and stored. Metabolism Active. Less active. These studies show that once ejaculated, sperm can survive and be functional up to five days in the reproductive tract. The number of sperm in a single ejaculate ranges from 40 million to million—the average is about million 1. For every ovum ovulated, about 1 billion sperm are produced 1. However, most ejaculated sperm are either dead or incapable of fertilizing 1. The fluid from accessory sex organs that make up most of semen is called seminal plasma , which is alkaline, thick, and rich in sugar fructose as a nutrient for the sperm 1.

Research shows that increasing age is associated with decreasing sperm quality. Sperm quality includes its motility ability to reach an egg , structure, and semen volume Sperm number and concentration per ejaculate varies individually, with some people having a low sperm count or absence of sperm 1.

When it comes to age and effectiveness, the American Fertility Society recommends an age limit of 50 for semen donors This is commonly known as being intersex. There have been no documented cases where one person has both functional ovaries and testes.

Fertility for all genders is a combination of many factors, including age, diet, genetics, substance use, stress levels, illness, and environmental factors 1. Both people with testes and people with ovaries have a lot of sperm and eggs, but only a tiny number of these cells are ever used when it comes to forming another human.
