Gonadal arteries

The primary function of gonadal arteries is to ensure an adequate supply of blood to the reproductive organs, which is vital for their health and functionality. In males, the gonadal arteries facilitate the perfusion of the testes, allowing for the production of sperm and testosterone—essential components of male reproductive health. In females, these arteries support the ovaries, ensuring proper delivery of hormones such as estrogen and progesterone, which regulate the menstrual cycle and influence fertility. Furthermore, by maintaining the health of the reproductive organs through their blood supply, the gonadal arteries play a pivotal role in overall reproductive capacity and sexual function, impacting aspects of health that reach beyond reproduction itself.

Gonadal arteries can be found originating from the abdominal aorta, typically at the level of the second lumbar vertebra (approximately 5 centimeters above the umbilicus). They descend along the posterior abdominal wall and are notably different in males and females. In males, the gonadal arteries travel into the inguinal canal, where they reach the testes, lying along the spermatic cord. In females, the arteries proceed to the ovaries, following a course along the suspensory ligament of the ovary, which connects the ovaries to the pelvic wall. This distinct pathway enables these arteries to effectively supply the necessary blood to their respective gonadal structures.

• Gonadal arteries develop from the embryonic mesonephric arteries and can vary in size and path between individuals.
• In addition to providing blood to the gonads, these arteries also supply blood to surrounding structures, including parts of the ureters.
• The right gonadal artery generally is longer than the left due to differences in anatomy related to the position of the inferior vena cava.
