[1] While varicocele is the diagnostic term for swelling in the valveless venous distribution of the male pampiniform plexus, this embryological structure, common to males and females, is often incidentally noted to be swollen during laproscopic examinations in both symptomatic and asymptomatic females. [2]
[1] cremasteric muscle and fascia, formed from a continuation of the internal oblique muscle and its fascia. [1] internal spermatic fascia, continuous with the transversalis fascia. [1] The normal diameter of the spermatic cord is about 16 mm (range 11 to 22 mm). [2] It is located behind the tunica vaginalis. [3]
I did the diagram myself based on the one found on the book "Gray's anatomy" 36th edition, Williams & Warwick, 1980; and a diagram found of the review "Formation and organization of the mammalian sperm head" from Kiyotaka Toshimori and Chizuro Ito.

The veins emerge from the back of the testis, and receive tributaries from the epididymis. [1] They unite and form a convoluted plexus, called the pampiniform plexus, which constitutes the greater mass of the spermatic cord; the vessels composing this plexus are very numerous, and ascend along the cord, in front of the ductus deferens.

An average adult testicle measures up to 5 cm × 2 cm × 3 cm (2 in × 3 ⁄ 4 in × 1 + 1 ⁄ 4 in). The Tanner scale, which is used to assess the maturity of the male genitalia, assigns a maturity stage to the calculated volume ranging from stage I, a volume of less than 1.5 cm 3; to stage V, a volume greater than 20 cm 3.
The tunica albuginea is a dense, [1] [2] blue-white [3] layer of fibrous tissue surrounding the testis. [1] [4] It is the middle of three envelopes forming the capsule of the testis; it is deep to the visceral layer of tunica vaginalis, and superficial to the tunica vasculosa testis (vascular layer of testis).
The epididymis (/ ɛ p ɪ ˈ d ɪ d ɪ m ɪ s /; pl.: epididymides / ɛ p ɪ d ɪ ˈ d ɪ m ə d iː z / or / ɛ p ɪ ˈ d ɪ d ə m ɪ d iː z /) is an elongated tubular genital organ attached to the posterior side of each one of the two male reproductive glands, the testicles.
