Human beings are born biologically either female or male. Depending on our development, throughout the first stages of life the sexual characteristics will be marked and the differences between both sexes will become more evident.
These sexual characteristics can be of one of the following two types:
Primary sexual characteristics: these are those directly related to reproduction, that is, the sexual organs and the corresponding glands. Secondary sexual characteristics: these are the characteristics that are not directly related to reproduction and that mark the physical differences between men and women. The most notable are the following:
FEMALE
MALE
The highest voice. The deepest voice. Development of the mammary glands. Muscle development. Wider hips. Wider shoulders and back. Less body hair. More body hair. Increased hair in the armpits and pubes.
Furthermore, during puberty, the first ejaculations (exit of semen through the urethra) appear in males and the first menstruations (exit through the vagina of the lining of the uterus when fertilization does not occur) in males. female sex.
In this text, we will focus on the primary sexual characteristics of living beings of the male sex, specifically, their reproductive system.
What organs and glands make up the male reproductive system?
The male reproductive system is located in the lower part of the trunk, in the pelvis. In addition, your organs can be classified taking into account those located inside the abdomen and those that are located outside and, therefore, can be seen without the need for medical tests.
The following diagram shows the aforementioned classification and the organs of each type:
This table shows the different parts of the male reproductive system with a brief description:
EXTERNAL
PENIS
Organ responsible for expelling semen with sperm. In addition, it has a urinary function as it is responsible for expelling urine.
It is made up of three cylindrical structures: the corpora cavernosa, the corpus spongiosum and the glans.
SCROTUM: TESTICLES AND EPIDIDYMIS
The scrotum is a thick skin sac that surrounds and protects the testicles, which are the male gonads whose main functions are to produce sperm (male gametes) and testosterone (the main male hormone). For its part, the epididymis collects sperm and offers them the appropriate conditions to mature and acquire the ability to move.
INTERNAL
CREMASTER
Muscle that allows the testicles and scrotum to move toward or away from the body.
DUCT DEFERENTS
Thin tubes that start from the epididymis and transport sperm to the seminal vesicles.
SEMINAL VESICLES
They are located under the bladder and are responsible for producing semen, which is liquid in which sperm move.
PROSTATE
It is the size of a walnut and produces part of the seminal fluid that protects and nourishes the sperm found in the semen.
URETHRA
It has a double function, in both men and women, it is the duct through which urine is expelled. However, in men it is also responsible for allowing semen to pass to the outside.
COWPER OR BULBOURETHRAL GLANDS
They are located under the prostate and prepare the urethra for the passage of semen through it thanks to the secretion of a liquid that allows it to pass more easily.
In the following images you can see the location of this device within the male human body in both front and profile views:
What are the functions of the male reproductive system?
The male reproductive system has three main functions:
Manufacture, store, preserve and transport sperm (male reproductive cells) and semen. Depositing sperm inside the female reproductive system so that the female egg can be fertilized and give rise to a new human being. Manufacture and secrete male hormones that serve to maintain the apparatus and the development of male sexual characteristics.
What are the most common diseases that can occur in this device?
Like the rest of the systems of the human body, it also presents a series of diseases that directly affect it. Among the most common are the following:
CANCER OF THE TESTICLES, PENIS OR PROSTATE
Malignant tumors that appear in any of the mentioned areas and that must be treated.
PEYRONIE’S DISEASE
Formation of a fibrous band on the penis that causes it to deviate or curve when erect.
PHIMOSIS
It mainly affects children under 10 years of age and consists of strangulation of the orifice of the foreskin (fold of skin that covers the glans) which is too small and does not allow it to retract so that the glans (final or extreme part of the penis) can emerge. .
URINARY INFECTIONS
They are more common in women, but men can also have them. They are produced by bacteria that enter the urethra and infect the urinary tract.
ORCHITIS
Inflammation of one or both testicles, usually caused by an infection.
VARICOCELE
Dilation of the veins in the testicles, commonly known as varicose veins.
Furthermore, there are calls STDs, diseases of sexual transmission, such as candidiasisthe chlamydiathe gonorrheahe Genital herpesthe hepatitis Bthe syphilis or the AIDS. These diseases are caused by bacteria, fungi and viruses that are transmitted through sexual contact and, sometimes, from mothers to fetuses through the umbilical cord.
In the case of men, certain functional anomalies can also occur such as premature ejaculation (expulsion of semen before what may be considered convenient), erectile dysfunction (maintenance of the erect penis) and male infertility (inability to fertilize an egg for various reasons).
What can be done to prevent these diseases or treat them when they occur?
A good hygienea Healthy life Regarding nutrition, rest and balance in vital activities, they are always the best recommendation for prevention against these and other diseases. Furthermore, it is important to be alert to the signs that the organism itself gives.
Once you have any disease, it is key to early medical diagnosis and receive the most appropriate treatment in each case and for each person.
To finish, we leave some activities to practice.
