Sperm develops in the testicles within the system of tubes called seminiferous tubules. At birth those tubules inside the testicles contain simple cells, then when puberty arrives the male testosterone and other hormones cause the cells to transform into sperm cells.
because spermatozoa and developing cells produce surface antigens that are recognized as foreign by the immune system
The structure of the testis responsible for producing spermatozoa is the seminiferous tubules. These tubules are lined with germinal epithelium, where spermatogenesis occurs, leading to the formation of sperm cells. The process involves the differentiation of spermatogonia into mature spermatozoa, which are then released into the lumen of the tubules. After maturation, the sperm are transported to the epididymis for storage and further development.

The testicles produce sperm once the male is beginning to reach sexual maturity.
The testes produce spermatozoa (sperm).
The spermatozoa is formed in the testis and is stored in the epididymis. While traveling through the epididymis the sperm mature and gain motility and the ability to fertilize.
produce sperm
The fetal testis descends into the scrotum through a structure called the inguinal canal. This canal is a passage in the lower abdominal wall that allows the testis to move from the abdomen to the scrotum during development.
