Question
Chapter 27.4, Problem 10AYLO
Summary Introduction
To discuss:
The composition of semen and main percentages of its principal components. Functions of fructose, semenogelin, clotting enzyme, prostaglandins, and serine protease. Clinical relevance of prostate-specific antigens (PSAs).
Introduction:
Semen is the fluid part that is ejaculated out during male orgasm. Semen consists of several functional constituents in it, since it is produced by the outcome of different accessory male reproductive organs. A typical adult male ejaculates 2 to 5mL of semen per ejaculation.

- HEALTHY 42-YEAR-OLD MAN PRESENTED TO THE EMERGENCY DEPARTMENT AFTER THE ACUTE ONSET OF penilepain during sexual intercourse. The erect penis had inadvertently collided with his partner’s perineum. Heheard a snap, noticed a rush of blood from the meatus, had immediate detumescence, and had severe pain. The penile“fracture” refers to a tear in the tunica albuginea, the watertight fibrous outer sheath of the corpora caver-nosa that isresponsible for maintaining the structural integrity of an erection. Disruption of the tunica results in a loss of bloodoutside the corpora, causing a hematoma. The classic eggplant deformity (swelling, discoloration, and deviation awayfrom the defect in the tunica) can be seen. If the fracture involves the urethra, blood will extravasate through theurethra.
