Reproductive organ as

Reproduction can be defined as the biological process of producing a new individual or an offspring identical to the parents. This process ensures the increase in the number of individuals of a species when conditions are favorable. It is one of the fundamental characteristics of living things and an essential life process.

There are mainly two types of reproduction –

This process of reproduction is very complex and involves the formation and transfer of gametes, followed by fertilization, the formation of the zygote, and embryogenesis.

This process of reproduction involves only one parent and the new offspring produced is genetically similar to the parent.

All human beings undergo a sexual mode of reproduction wherein, two parents are involved in producing a new individual. Offspring are produced by the fusion of gametes (sex cells) from each parent. Hence, the newly formed individual will be different from parents, both genetically and physically. In human beings, both males and females have different reproductive systems; hence, they are known to exhibit sexual dimorphism. Males have testes- also called testicles, while the females have a pair of ovaries.

The reproduction in human beings involves the fusion of male and female gametes produced in their reproductive system. The male reproductive system is different from the female reproductive system, both in structure and in function.

The male gametes, i.e., sperms are produced within the male reproductive system. Sperms are small unicellular structures with a head, middle piece, and a tail. The male reproductive system consists of :

A pair of oval-shaped organs masked in a pouch called scrotum which is responsible for the production of sperms and the male hormone testosterone.

It is a sac-like organ that hangs below the penis and behind it. It is the house of the testicles, or testes, and maintains an appropriate temperature required for the production of sperms. Vas deferens: The sperms produced in the testes are stored in a tube called the epididymis. Here the sperms get matured and pass to urethra through the muscular tube called vas deferens.

This includes three glands, namely seminal vesicles, prostate gland, and Cowper’s gland. The secretions from accessory glands mix to form a fluid called semen. It nourishes the sperm, increases the volume, and helps in lubrication. Penis: Penis is a cylindrical tube like structure that serves as both a reproductive organ as well as an excretory organ. It helps to put sperms into the vagina during sexual intercourse. (Image will be uploaded soon)

The female reproductive system is active before, during, and after fertilization as well. It consists of the following parts:

Ovum is produced and stored in Ovaries. A female hormone is produced within the ovaries called Estrogen.

They are the site of fertilization. They connect ovaries with the uterus.

Uterus is the site of development for the embryo.

It is the part that connects the cervix to the external female body parts. It also forms the route for the penis during coitus as well as a fetus during delivery. (Image will be uploaded soon)

Female reproductive system has two functions –

During puberty, eggs in the ovaries start to mature. One of the ovaries releases the mature ovum every 28 to 30 days and the process is called ovulation.

The process in which Zygote is produced by the fusion of sperm with egg is called Fertilization. It is a crucial stage of reproduction in human beings. The fertilized egg is called the zygote. Zygote starts to divide into many cells and develops into an embryo. Embryo moves into the uterus and gets attached to its walls. This process is referred to as implantation, and the implanted embryo eventually develops into a fetus.

Reproduction can be defined as the biological process of producing a new individual or an offspring identical to the parents. This process ensures the increase in the number of individuals of a species when conditions are favorable. It is one of the fundamental characteristics of living things and an essential life process.

The two types of reproduction are – Sexual Reproduction – This process of reproduction is very complex and involves the formation and transfer of gametes, followed by fertilization, the formation of the zygote, and embryogenesis. Asexual Reproduction –  This process of reproduction involves only one parent and the new offspring produced is genetically similar to the parent.

The male reproductive system consists of : Testicles (testes):  A pair of oval-shaped organs masked in a pouch called scrotum which is responsible for the production of sperms and the male hormone testosterone. Scrotum:  It is a sac-like organ that hangs below the penis and behind it. It is the house of the testicles, or testes, and maintains a temperature that is required for the production of sperm by it. Vas deferens:  The sperms produced in the testes are stored in a tube called the epididymis. Here the sperms get matured and pass to urethra through the muscular tube called vas deferens. Accessory Glands:  This includes three glands, namely seminal vesicles, prostate gland, and Cowper’s gland. The secretions from accessory glands mix to form a fluid called semen. It nourishes the sperm, increases the volume, and helps in lubrication. Penis:  Penis is a cylindrical tube that serves as both a reproductive organ as well as an excretory organ.
