Males have two testicles of similar size contained within the scrotum, which is an extension of the abdominal wall. [1] Scrotal asymmetry, in which one testicle extends farther down into the scrotum than the other, is common. This is because of the differences in the vasculature's anatomy. [1]

The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia. Each testicle develops in the lower ...
The testicle in the male and the ovary in the female are called the primary sex organs. [1] All other sex-related organs are known as secondary sex organs . The outer parts are known as the genitals or external genitalia , visible at birth in both sexes, [ 1 ] while the inner parts are referred to as internal genitalia , which in both sexes ...
The testicles are two gonads that produce sperm by meiotic division of germ cells within the seminiferous tubules, [1] and synthesize and secrete androgens that regulate the male reproductive functions. The site of production of androgens is the Leydig cells that are located in the interstitium between seminiferous tubules. [1]
"It would be like calling the penis 'the scrotum' or 'testicles,'" she says. "There’s a labia majora , a labia minora, a clitoris and a vulvar vestibule that can all have different issues ...
The tunica vaginalis is a pouch of [2] serous membrane [3] within the scrotum that lines the testis and epididymis (visceral layer of tunica vaginalis), and the inner surface of the scrotum (parietal layer of tunica vaginalis).
