The male reproductive organs are a group of organs involved in the reproductive systemand is divided into two parts, namely internal organs and external organs. In the process of reproduction, it is necessary also certain hormones to help the function of the male reproductive organs. Check out the following explanation.
Male reproductive organs are owned from birth, but the new reproductive ability will begin after puberty. Puberty begins at the age range of 9-15 years.
Broadly speaking, the male reproductive organs function to produce semen and sperm in them, then enter the sperm into the female reproductive organs for the fertilization process. Semen containing sperm is usually thick, but sometimes sperm can also be watery.
Male Reproductive Organs
Based on its location, the male reproductive organs are divided into two parts, namely:
- External organs
The external male reproductive organs consist of three organs namely the penis, scrotum (testicles), and testes. Apart from being a sexual organ in men, the penis also functions as a way out of urine from the body through a channel called the urethra.
While the scrotum, acts as a temperature control system in the testes. The temperature of the testes is closely related to the production of healthy sperm. In addition to producing sperm, the testes also function to produce the hormone testosterone, which is the main hormone in men.
- Internal organs
The male reproductive organs consist of several organs including the epididymis, prostate gland, bulbourethral gland, seminal vesicles, urethra, and vas deferens.
The epididymis functions to store sperm cells produced in the testes and transport immature sperm to the tube vas deferens to become mature sperm.
Vas deferens The tube itself is a tube that serves to transport mature sperm to the urethra, the tube that carries urine or sperm out of the body, in preparation for ejaculation. While the seminal vesicles function as a producer of fructose fluid which is used by sperm as a source of energy during activities.
The prostate gland contributes to providing additional fluid for the ejaculation process. Prostate fluid also helps sperm to stay healthy. Meanwhile, the bulbourethral glands play a role in producing a fluid that serves to lubricate the urethra and neutralize the acidity that may exist due to residual urine droplets.
All of these male reproductive organs play an important role in every stage of the reproductive process, from fertilization to pregnancy. When a man or boy who has gone through puberty is sexually aroused, his body will react. Initially, there is a change in the size of the penis because the blood vessels become larger so that more blood enters. Enlargement of the penis is accompanied by changes in texture to become stiffer, this is what is called an erection condition.
After a man has an erection, which is then followed by ejaculation, the penis will secrete semen along with the sperm in it. In each ejaculation, the volume of semen released is 2.5 to 5 milliliters. Each milliliter contains more than 20 million sperm. After the sperm enters the vagina, the sperm will continue to move towards the cervix until the egg cell reaches the fertilization process and finally pregnancy occurs.
Male Reproductive Hormones
The entire male reproductive system depends on hormones, which are chemicals that regulate the activity of cells and organs in the body.
When boys enter puberty, their bodies will produce more gonadotropin hormones. This hormone is produced by the hypothalamus gland in the brain.
In another part of the brain, namely the pituitary gland, a hormone called luteinizing hormone and follicle-stimulating hormone (follicle-stimulating hormone).
The following is a further explanation of hormones in the male reproductive organs:
- Follicle stimulating hormone (follicle-stimulating hormone)
This hormone is very important so that the male reproductive organs can produce sperm. Every day the production of sperm produced can reach 300 million, with the formation period of each sperm about 65-75 days.
- Luteinizing hormone
When this hormone is released into the blood, there will be production and release of testosterone as the main male hormone.
- Testosterone
Testosterone production at puberty triggers a variety of physical changes. Such as enlargement of the testicles and scrotum, an increasingly elongated penis, a louder voice, and the growth of hair around the genitals, face and armpits. Some teenage boys also experience significant weight and height gain after entering puberty. Testosterone will also affect bone mass and sexual arousal.
Providing adequate understanding to boys about the male reproductive organs, preferably starting from childhood to adolescence. This is intended to prevent dangerous sexual behavior and unplanned pregnancy, early on.
