What Is the Reproductive System?

Anatomical name. Department of breeding offspring, continuing the general name of the organs of the race. The organs of the reproductive system are different between males and females, but according to their functions, they are composed of gonads, reproductive ducts and accessory organs. The reproductive organs, through their various activities, fertilization, pregnancy, and other physiological processes, achieve the role of reproduction offspring. According to its location, it can be divided into internal and external genitalia.

Reproductive system I. Male reproductive system:

A series of organs in which men perform reproductive functions, namely the gonads, ducts, accessory glands, and external genitalia. The male gonad is the testis. The ducts are the epididymis, vas deferens, ejaculation ducts and urethra. The accessory glands are seminal vesicles and prostate. The seminal vesicle glands secrete a yellow viscous fluid. The excretory duct and vas deferens synthesize ejaculation ducts, and the prostate secretes a milky white slurry, which together with the seminal vesicle gland secretions form semen. Its excretory opening is open to the urethra. The external genitalia has a penis and scrotum. The scrotum is a sagging skin sac containing the testis and epididymis. The penis can be divided into three parts: root, body and head. There is a circular coronal groove between the penis head and the penis body.

Reproductive system II. Female reproductive system:

A series of organs in which a woman performs reproductive functions, namely the gonads, ducts, accessory glands, and external genitalia. The female gonad is the ovary. Conduits include fallopian tubes, uterus and vagina. The fallopian tube is a pair of curved and long pipit-shaped muscular ducts with the medial end opening to the uterine cavity and the lateral end opening to the peritoneal cavity. The fallopian tube is a place for human fertilization, and fertilized eggs develop in the first few days. Clinically, the fallopian tubes, together with the ovaries, are called uterine appendages. The uterus resembles an inverted pear-shaped, slightly flat front and back, and can be divided into four parts: the bottom, body, isthmus and neck. The uterus is where the embryo develops. The vagina is a flat muscular duct that stretches back and forth. It is a large stretch and is the pathway for menstruation and fetal delivery. There is a semilunar or ring-shaped mucosal fold in the virgin's vaginal opening, called the hymen. Female accessory glands include vestibular glands, urethral glands, and so on. External genitalia, also known as female vulva, include genitals, labia majora, labia minora, clitoris, and vaginal vestibule.

Reproductive system III. Clinical diseases:

Sexually transmitted diseases (STDs) and tumors of the reproductive system are two common types of reproductive system diseases that affect both the safety and quality of sexual life, and cause dysuria in men, sexual dysfunction, pain in women, and ectopic pregnancy. , Infertility and other complications; may also threaten fetal health, cause abortion and stillbirth, or directly affect the offspring population quality.

(1) Common STDs:

STDs are a collective term for a group of infectious diseases transmitted primarily through sexual contact. China's common STDs include AIDS [AIDS, including human immunodeficiency virus (HIV) infection], syphilis, gonorrhea, genital tract trachomatis infection, condyloma acuminatum, genital herpes, soft chancre, and sexually transmitted lymphogranuloma, etc., which are government regulations Legal surveillance of disease.

(2) Syphilis:

Syphilis is a chronic infectious disease caused by Treponema pallidum that can cause multiple organ disease and damage throughout the body. Congenital syphilis (CS), also known as fetal syphilis, is obtained by the fetus through the placenta. It is often caused by early syphilis in pregnant women. CS is far more harmful than adult syphilis. In recent years, the number of syphilis cases in China has been ranked among the top three in China for Class A and B legally reported infectious diseases.

(3) Gonorrhea:

Gonorrhea is a purulent inflammatory disease of the urogenital system caused by Neisseria gonorrhoeae. Economically developed areas and coastal areas are areas with high incidence of gonorrhea. Gonorrhoea mainly occurs in young adults aged 20 to 49, and there are significantly more men than women.

(4) AIDS:

AIDS is a malignant infectious disease caused by severe infection of somatic immunity caused by HIV infection. The mortality rate is extremely high and it is a major public health problem worldwide.
