Epididymis: Crescent-shaped, close to the upper end and posterior edge of the testicles. The upper end is the caput epididymis, the middle part is the body of the epididymis, and the lower end is the cauda epididymis. The epididymis is an organ that temporarily stores sperm and secretes epididymal fluid for sperm nutrition. Promote further maturation of sperm. The epididymis is a common site for tuberculosis.

Vas deferens: It is the direct continuation of the epididymal duct, about 50cm in length, with thicker wall, more developed muscle layer and small lumen. When touched in vivo, it appears as a solid round cord. The vas deferens starts from the end of the epididymis and enters through the inguinal canal along with the spermatic cord. In the pelvic cavity, behind the bladder floor and in front of the rectum, the vas deferens on both sides gradually approach and expand into the ampulla of the vas deferens.

Ejaculatory duct: The end of the ampulla of the vas deferens tapers and merges with the efferent duct of the seminal vesicle to form the ejaculatory duct. The ejaculatory duct opens into the prostate part of the urethra

Spermatic cord: It is a soft round cord-like structure that passes from the abdominal ring of the inguinal canal through the inguinal canal, exits the subcutaneous ring and extends to the upper end of the testis. The ligated part of the vas deferens is the spermatic cord

Seminal vesicle: It is an oblong sac-like organ located behind the base of the bladder and on the lower outside of the ampulla of the vas deferens, one on each side.

Prostate: An unpaired solid organ located between the bladder and urogenital diaphragm. The secretion of the prostate is the main component of semen and contains prostaglandins.

The bulbourethral glands are a pair of pea-sized spherical glands located in the deep transverse muscles of the perineum. The efferent duct of the gland opens into the bulb of the urethra

Cervix: The section located within the uterine wall, with the smallest diameter, connecting the fallopian tube to the uterine cavity.

Isthmus: short and straight, where fallopian tube ligation is often performed

Ampulla: Thick and long, with rich blood supply, accounting for about 2/3 of the total length of the fallopian tube. Most eggs are fertilized in the ampulla.

Infundibulum: The enlarged part at the end of the fallopian tube. Around the abdominal opening of the fallopian tube, many slender finger-like protrusions called fallopian tube fimbria are formed on the edge of the end of the fallopian tube, covering the surface of the ovary. One of the larger protrusions connected to the ovary is called the ovarian fimbriae

Location: Located in the center of the small pelvis, between the bladder and rectum and connected to the vagina at the lower end

Shape: The uterus of an unpregnant adult is slightly flattened from front to back and inverted pear shape. The uterus is divided into three parts: fundus, body, and neck. The fundus of the uterus is the part above the level of the uterine opening of the fallopian tube, wide and round. The cervix is ​​a narrow cylindrical part at the lower end, which is a common site for cancer tumors. Between the fundus of the uterus and the cervix is ​​the body of the uterus. The upper part of both sides of the uterus that communicates with the fallopian tube is called the uterine horn. The narrower part where the body of the uterus connects with the upper end of the cervix and vagina is called the uterine isthmus.
