As children grow and discover their reproductive organs, they begin to show interest in this topic. Without a doubt, this is a good time to explain in a simple way what their reproductive organs are, what function they perform and how they differ from the reproductive system of the other gender. In Stage Infant we know that it is not an easy task for many parents, that is why we want to give you a hand, so that you can talk to your children about this topic with more fluency and clarity.

What is the reproductive system and what function does it perform?

The human reproductive system is the set of organs and ducts of the body that participate in reproduction, that is, in the creation of new individuals of the species. Although the reproductive system is different for girls and boys, it is basically responsible for perpetuating the life cycle of humans in nature, so it is of vital importance for the maintenance of the species. However, it also intervenes in other functions of the body.

The reproductive system is related to sexuality and the synthesis of sexual hormones, which not only define gender, but also develop sexual characteristics in each person. Likewise, they are related to the formation of muscle mass, bone density, body hair and the consolidation of one or another type of voice, at the same time that they intervene in the regulation of some metabolic and cardiovascular functions.

What organs make up the female reproductive system?

The female reproductive system is made up of two parts: an internal part that includes most of the system, and an external part whose main function is to protect the entrance to the internal part. The main female reproductive organs are:


It is one of the most important internal female reproductive organs since they produce the female ovules or gametes, which are nothing more than the female reproductive cells. The ovaries are shaped like a small egg and are located where the fallopian tubes end.

Fallopian tube

Basically, the fallopian tubes are the tubes that connect the ovaries with the uterus. They play an essential role during female reproduction since the ovules travel through them to meet the male sperm. They are cord-shaped and are located at both ends of the uterus.


It is a kind of cavity with thick and muscular walls. It is precisely to this cavity where the ovules arrive after being fertilized and where the gestation takes place, once the pregnancy takes place. The uterus is cup-shaped and located in the lower abdomen.


The vagina is the tube that connects the uterus with the outside. It is a kind of muscular channel that has the function of receiving sperm during sexual intercourse and protecting the rest of the reproductive system from infections in the environment. It is also the channel through which the baby comes out at the end of the pregnancy.


This is the outermost part of the female reproductive system. It is formed by a kind of skin fold, known as inner and outer lips, which protect the entrance to the internal area of ​​the reproductive system.

What organs make up the male reproductive system?

Like the female reproductive system, the male reproductive system is made up of an external and an internal part that, together, guarantee its proper functioning. Its main organs include:


Similar to the female ovaries, the male testicles are basically responsible for producing sperm, which are nothing more than male reproductive cells. They are located inside the bag that hangs below the penis and are shaped like a small egg.

Also known as the vas deferens, they connect the testicles with the ejaculatory ducts. Its main function is to transport mature sperm to the urethra, where they will mix with other fluids before going outside.

ejaculatory ducts

Also known as afferent ducts, they connect the seminal ducts with the secretory duct. In other words, they are the pathways through which semen is expelled from the male body.


It is a very important internal organ that connects to the testicles through the vas deferens. Its main function is to exert pressure so that the semen is expelled through the urethra to the outside. It also closes the bladder passageway during sexual intercourse to prevent it from releasing its contents.


It is an external organ, with a tubular shape, through which the semen and spermatozoa go outside to be deposited inside the female reproductive system. It is also the organ through which male urination occurs. The penis is made up of the glans, the cone-shaped corpus spongiosum located just at the tip, and the foreskin, which is the skin that covers the glans.

How does human reproduction work?

Human reproduction begins long before the sexual act. It all starts when one of a woman’s ovaries releases a mature egg as part of the female menstrual cycle. The expelled egg travels through the fallopian tubes on its way to the uterus. If during that journey it does not find any male sperm to fertilize it, upon reaching the uterus it is expelled through the vagina when the period occurs, which occurs approximately every 28 days.

If the egg is fertilized by a sperm, then it reaches the uterus and nests in its walls. From this moment on, the ovum begins to reproduce and becomes an embryo, a kind of very small egg that feeds on the nutrients and oxygen transmitted by the mother through the umbilical cord.

During the following months the embryo transforms into a fetus and continues to grow. Then the organs form, the different parts of the body take shape, and about 9 months later the baby is born. During birth, the baby passes through the vagina, and once outside, the umbilical cord is cut. Already in the world, the baby continues to grow, learns to walk and gains more and more autonomy until he becomes an independent being from his parents.
