Axial segment of the right scrotal hemi-sac anatomy diagram. The external spermatic fascia (green), cremaster muscle (red), internal spermatic fascia (light blue), and parietal and visceral laminae of the tunica vaginalis (pink) are represented from the outside to the inside. The vaginal cavity is indicated by the star. spermatic cord (1), testis (1) (2)
A network of fibrous connective septa emerges from the inner surface of the tunica albuginea and extends radially through the testis, reaching the mediastinum and dividing the parenchyma of the testis into about 250–300 lobules; these are approximately cone-shaped, with their bases at the level of the tunica albuginea and their apex towards the mediastinum.
Every lobule is made up of 1–4 tubuli seminiferi, each measuring 30–180 cm in length; these tubes are highly convoluted and converge towards the mediastinum, where they emerge at the level of the rete testis, straightening out (tubuli recti).
The veins from the didymus and epididymis anostomose in a plexus (pampiniform plexus) at the level of the posterior margin of the testis, forming convoluted wider blood vessels that anostomose in a plexus (pampiniform plexus) and become part of the spermatic cord. This cord gives rise to the testicular vein, which connects the inferior vena cava on the right and the ipsilateral renal vein on the left.

The seminal vesicles are two sacculated pouches that contain a substantial amount of seminal fluid. Each vesicle is about 5 cm long on average, but it can be much shorter. Laterally, upward, and backward, the wide end is directed. Its narrow end is very similar to the contralateral vesicle’s. The seminal vesicles are nearly vertical when the urinary bladder is distended, but nearly horizontal when the bladder is empty. The seminal vesicles are encased in a thick sheath made up of smooth muscle and fibrous tissue that is bound to the urinary bladder’s posterior side. The peritoneum covers the upper portions, which are separated from the rectum by the rectovesical pouch. The rectovesical septum separates their lower parts from the rectum. The ureters’ terminal portions and the ductus deferens’ ampullae are medial to the vesicles, while the prostatic and vesicle venous plexuses are lateral.
Each seminal vesicle is made up of a coiled tube that emits multiple diverticula before ending blindly above. To form a duct, its lower end narrows and straightens. This connects the corresponding ductus deferens, and the ejaculatory duct is the tube that results from this union.

In male anatomy, the ejaculatory ducts (ductus ejaculatorii) are paired structures.

[1] The vas deferens and the duct of the seminal vesicle join to form each ejaculatory duct.

Ejaculatory duct – medical meaning and pronunciation

[2] At the seminal colliculus, they pass through the prostate and open into the urethra. Semen passes via the prostate gland, reaches the urethra, and leaves the body through the urinary meatus during ejaculation. [three]
Women and men go through the same stages. However, in men, the excitation process is very fast, whereas in women, it takes a little longer (normally). Men’s plateau periods are also shorter. Women’s refractary periods would be shorter than men’s. Because of their shorter refractary time, women are more likely to develop multiorgasms.
The emission stage and the expulsion stage are the two stages of ejaculation.
[4] The emission stage includes many ejaculatory duct structures: contractions of the prostate gland, seminal vesicles, bulbourethral gland, and vas deferens force fluids into the prostatic urethra.
[3] The sperm is held here before ejaculation takes place. The seminal fluid trapped in the prostatic urethra is propelled through the penile urethra and expelled through the urinary meatus by contracting muscles at the base of the penis. Due to the contraction of the muscles that drive it, the ejaculate is expelled in spurts. These muscle contractions are associated with male orgasm sensations. (5)

The sperm is propelled through the prostate to the prostatic urethra, which empties into the intermediate portion of the urethra and then into the spongy urethra, which stretches the length of the penis to the body exterior.
a procedure for male sterilization or permanent contraception that is performed surgically. During the procedure, the male vas deferens is severed and then bound or sealed in such a way that sperm cannot reach the seminal stream (ejaculate) and therefore fertilization is prevented.
