Testicles Plush Toy

Want a super fun and cute way to learn more about the human body? GiantMicrobes plush toys are here to entertain, educate, and cuddle. These plush toys are about 5 inches in height.

This toy represents testicles, the primary reproductive organs in those assigned male at birth. The testicles have two functions: production of sperm and production of hormones.

Sperm are produced within tube-like canals called seminiferous tubules. There are hundreds of these 2-foot long tubules. Sperm mature for about 100 days within long coiled tubes called the epididymis. At release, sperm travel through the vas deferens into the urethra and then outside of the body.

Testosterone is the main hormone produced by the testicles. This hormone is secreted by cells that lie between the seminiferous tubules, known as the Leydig cells. The testicles produce other substances as well, such as inhibin B, insulin-like factor 3 and oestradiol.
