AI overview

A testicle (or testis) is the male gonad that produces spermatozoa, which travel through a series of ducts including the epididymis and vas deferens before exiting the body. It is the male equivalent of the ovary and is essential for male reproduction in humans and other animals.

The release of testosterone is regulated by luteinizing hormone (LH) from the anterior pituitary gland. Sperm production is controlled by follicle-stimulating hormone (FSH) from the anterior pituitary gland and by testosterone produced within the gonads.
