What is the difference between Egg and Sperm Cell Formation?

Gonads are the primary reproductive organs that produce the gametes. A pair of testes produce sperms in males and a pair of ovaries produce ovum in females. Spermatogenesis is the process by which the male gametes called “sperms” are formed from the primitive spermatogenic cells.

There are four major stages in spermatogenesis which include the stage of proliferation, growth, maturation, transformation. It is affected by factors like hormones and Sertoli cells. The process of formation of an egg cell is known as oogenesis, this process involves two meiotic divisions. Primary oocyte produces two daughter cells with 23 chromosomes after completing the meiosis I. Secondary oocyte completes 2nd meiosis only if fertilized. Oogenesis results in one large fertilized egg (zygote) and possibly three small polar bodies.

The egg cells and sperm cells are different cells present in the female and male sex, respectively. The two depend on themselves to recreate life, and when they come in contact together in the female reproductive system, there will be a reaction, and gestation commences, which is likely to lead to pregnancy. They are different in terms of their source. The egg cells are produced by the female reproductive system, while the sperm cells are sourced from the male reproductive system. The way they function is different.

The egg cells are created in the female ovaries, while the sperm cells are formed in the epididymis. A sperm cell is smaller than an egg cell. Both the sperm cells and egg cells undergo meiosis. When a female reaches a particular puberty stage, her eggs start to be released during her menstrual cycles, which usually occur monthly. Sperm cells are reproduced constantly in males, while a female is naturally born with millions of cells.

The most apparent difference between an egg cell and a sperm cell is that sperm is a reproductive cell from a male while the egg cells are from females. Both egg and sperm cells depend on each other for the reproduction of human life, and they both undergo meiosis. There is a difference in the formation time for both egg and sperm cells. The raw materials for egg cell production are formed while the fetus is still in the uterus. Every baby girl is born into a world with about 4 million egg cells in her ovaries. These eggs drop into the uterus once every month once she is at the age of sexual maturity. On the other hand, sperm cells are produced continuously. They die, but they also are replenished, and this process usually takes about three weeks. When the sperm cell completes its second lifecycle, it is done, and it cannot develop any further.

Meanwhile, once the egg drops into the uterus, it is halfway through the first and second stage of the lifecycle. It does not complete until sperm comes to fertilize it. The hormones are different, as testosterone is the essential hormone that is responsible for the production of sperm cells, estrogen is the female hormone that promotes the release of luteinizing hormone, which triggers the egg cell released from the ovary.

There are so many differences between egg and sperm cell formation. Egg cell is the reproductive cell of the female gender, while sperm cell is the reproductive cell of the male gender. During sexual intercourse, the sperm cell of a man will travel to meet the egg cell of a woman for fertilization. When there is fertilization, this will in turn lead to pregnancy.

According to research, egg cells are added to the fetus in the uterus after fertilization and those egg cells are about four million, and once the baby has reached the maturity stage, the eggs drop once in a month into the uterus, waiting for sperm cells to come for fertilization. But Sperm cells are produced in the male’s body and they die after three weeks upon which they are replenished. Egg cells are produced in the ovary of a woman in her reproductive system, while sperm cells are produced in the epididymis. Sperm cells are also smaller when compared with the size of the egg cells.
