The testes are two oval-shaped organs in the male reproductive system. We’ll go over the different structures within each testis and how they function. You’ll also learn about the kinds of ...
Testis, plural testes, also called testicle, in animals, the organ that produces sperm, the male reproductive cell, and androgens, the male hormones.In humans the testes occur as a pair of oval-shaped organs. They are contained within the scrotal sac, which is located directly behind the penis and in front of the anus.
The testes are twin oval-shaped organs about the size of a large grape. They are located within the scrotum, which is the loose pouch of skin that hangs outside the body behind the penis. While this location makes the testes vulnerable to injury (they have no muscles or bones to shield them), it provides a cooler temperature for the organs.
The testes are connected to the vital organs of the ventral body cavity via the spermatic cords. Nerves, blood vessels, and lymphatic vessels travel through the spermatic cords to support the testes. The vas deferens also passes through the spermatic cord carrying sperm out of the testes toward the prostate and urethra.

Testicle or testis is the male reproductive gland or gonad in all animals, including humans. It is homologous to the female ovary.The functions of the testes are to produce both sperm and androgens, primarily testosterone.Testosterone release is controlled by the anterior pituitary luteinizing hormone; whereas sperm production is controlled both by the anterior pituitary follicle-stimulating ...
Describe the structure and location of the testes. Testes in scrotum, temperature lower than the inside of the body, covered by tunica albuginea, which divides testes into lobules containing seminiferous tubules- Function-sperm production and production of testosterone.
In an adult male, or at least a male well into the stages of puberty, the testes are located within the scrotum. The scrotum is the sac external to the body that holds the testes, and lies below ...
Testicles, or testes, are oval-shaped organs located in the scrotum, just behind the penis and right in front of the anus on male humans. Each testis weighs 0.35 to 0.5 ounces ...
Animal reproductive system - Male systems: In anurans, amniotes (reptiles, birds, and mammals), and even some teleosts, testes are composed largely of seminiferous tubules—coiled tubes, the walls of which contain cells that produce sperm—and are surrounded by a capsule, the tunica albuginea. Seminiferous tubules may constitute up to 90 percent of the testis.
