A pyramid.
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.
Structure A. Testis
The ovaries.
The outer layer of the serous membrane that covers each testis is called the tunica vaginalis. It is a two-layered structure that surrounds and protects the testis within the scrotum.
The Sertoli cells usually form the blood-testis barrier.

Hydrocele is the abnormal accumulation of fluid in the scrotum.
The testicles produce sperm once the male is beginning to reach sexual maturity.
Sperm move from the testes to the epididymis to finish growing. The epididymis is the tubular structure on the top of the testis.
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.
They are produced in testis. There are tubules in testis
The testis produce the male androgen testosterone.
