The mesovarium is the portion of the broad ligament of the uterus that suspends the ovaries. The ovary is not covered by the mesovarium; rather, it is covered by germinal epithelium.
At first, the mesonephros and genital ridge are suspended by a common mesentery, but as the embryo grows the genital ridge gradually becomes pinched off from the mesonephros, with which it is at first continuous, though it still remains connected to the remnant of this body by a fold of peritoneum. In the male, this is the mesorchium, and in the female, this is the mesovarium.

The inguinal canal is a passage in the anterior abdominal wall on each side of the body, which in males, convey the spermatic cords and in females, the round ligament of the uterus. The inguinal canals are larger and more prominent in males.
The paired gubernacula, also called the caudal genital ligament, are embryonic structures which begin as undifferentiated mesenchyme attaching to the caudal end of the gonads.
The rectouterine pouch is the extension of the peritoneum into the space between the posterior wall of the uterus and the rectum in the human female.
The inguinal ligament, also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop.
The external iliac arteries are two major arteries which bifurcate off the common iliac arteries anterior to the sacroiliac joint of the pelvis.
In human anatomy, the inferior epigastric artery is an artery that arises from the external iliac artery. It is accompanied by the inferior epigastric vein; inferiorly, these two inferior epigastric vessels together travel within the lateral umbilical fold The inferior epigastric artery then traverses the arcuate line of rectus sheath to enter the rectus sheath, then anastomoses with the superior epigastric artery within the rectus sheath.
The sacrotuberous ligament is situated at the lower and back part of the pelvis. It is flat, and triangular in form; narrower in the middle than at the ends.
The round ligament of the uterus is a ligament that connects the uterus to the labia majora. It originates at the junction of the uterus and uterine tube. It passes through the inguinal canal to insert at the labium majus.
The uterine artery is an artery that supplies blood to the uterus in females.
The ovarian artery is an artery that supplies oxygenated blood to the ovary in females. It arises from the abdominal aorta below the renal artery. It can be found within the suspensory ligament of the ovary, anterior to the ovarian vein and ureter.
The broad ligament of the uterus is the wide fold of peritoneum that connects the sides of the uterus to the walls and floor of the pelvis.
The suspensory ligament of the ovary, also infundibulopelvic ligament, is a fold of peritoneum that extends out from the ovary to the wall of the pelvis.
The pelvic cavity is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet. Its lower boundary is the pelvic floor.
The ovarian vein, the female gonadal vein, carries deoxygenated blood from its corresponding ovary to inferior vena cava or one of its tributaries. It is the female equivalent of the testicular vein, and is the venous counterpart of the ovarian artery. It can be found in the suspensory ligament of the ovary.
The deep perineal pouch is the anatomic space enclosed in part by the perineum and located superior to the perineal membrane.
The perimetrium is the outer serosal layer of the uterus, derived from the peritoneum overlying the uterine fundus, and can be considered a visceral peritoneum. It consists of a superficial layer of mesothelium, and a thin layer of loose connective tissue beneath it.
The rectouterine fold is a bilaterally paired prominent ridge/fold of the peritoneum that represents the lateral boundary of the rectouterine pouch on either side. It is formed by the underlying rectouterine muscle. On either side, the rectouterine fold extends between the sacrum medially, and the base of the broad ligament of the uterus laterally.
The mesometrium is the mesentery of the uterus. It constitutes the majority of the broad ligament of the uterus, excluding only the portions adjacent to the uterine tube and ovary.
The development of the gonads is part of the prenatal development of the reproductive system and ultimately forms the testicles in males and the ovaries in females. The immature ova originate from cells from the dorsal endoderm of the yolk sac. Once they have reached the gonadal ridge they are called oogonia. Development proceeds and the oogonia become fully surrounded by a layer of connective tissue cells. In this way, the rudiments of the ovarian follicles are formed.
The fallopian tubes, also known as uterine tubes, oviducts or salpinges, are paired tubes in the human female body that stretch from the ovaries to the uterus. The fallopian tubes are part of the female reproductive system. In other vertebrates, they are only called oviducts.
