خصیے (Khyze) refers to the male reproductive glands known as testes. These glands are responsible for producing sperm and hormones, particularly testosterone, which plays a crucial role in male development and reproductive functions. In addition to their reproductive functions, خصیے also contribute to secondary sexual characteristics, such as increased muscle mass and body hair. They are located in the scrotum, which helps regulate their temperature for optimal sperm production. Proper functioning of خصیے is essential for male fertility and overall health.
