The semen may certainly be vitiated and diseased: the odor and color assume all the gradations of other secretions when in a morbid condition.
Semen not discharged is supposed to be absorbed, thereby adding to the strength and nutriment of the economy; but as it is furnished for a specific purpose, and its secretion depends much upon the play of our animal passions, and as they are rarely permanently idle, there is not only the inducement that the fluid be furnished, but also emitted, and hence we have nocturnal emissions. These, to a degree, are salutary; but they may happen so frequently that the function becomes disordered and perverted, and in some individuals the semen (unconsciously to them) escapes during sleep, or on the slightest local excitement of riding, walking, or on the action of the bladder or rectum.
The prostate gland, as has been stated, contributes much to the dilution of the semen; it may empty itself independently of it. The gland is composed of numerous cells, from which proceed some twenty or thirty pipes or passages that open in the urethra by the sides of the verumontanum, as shown in the drawing.

Morbid Secretions and Irritability of the Urethra.—I have stated that clap or gonorrhœa is one of the first and most frequent complaints of the generative apparatus. There are many secretions common to the urethra, such as those afforded by the various glands for the purpose of lubrication, &c.; and the lining membrane of the passage yields a moisture for its own protection, like the membrane of many other organs, such as the eyes, nose, mouth, and so forth, and these secretions may become unhealthy or vitiated, and give rise to symptoms that lead on to confirmed disease; and, what is still more remarkable, may assume many of the characters and appearances of gonorrhœa, but they rarely induce such constitutional disturbances as clap. The symptoms, consequences, and duration of clap, form its distinguishing features from any other discharge of the urethra: it is very important that such distinction should be understood, for the treatment of the two affections differs most materially; the one is an affection of weakness, and the other of an inflammatory and pestilential nature. The symptoms of clap are as follow: there is usually first felt an uneasy sensation at the mouth of the passage or urethra. The patient is frequently called upon to arrange his person; that uneasy sensation sometimes amounts to an itching (occasionally of a pleasurable kind) the feeling extends a little way up the penis; there is oftentimes an erection and a desire for intercourse, which, if indulged in, the sooner develops the disease. The itching alone will not convey the disease from one person to another; but if intercourse be held, the action of the inflamed vessels is accelerated, and a purulent secretion which is infectious is urged forth and emitted with the semen: therefore the very symptom of the tingling or itching, for it rarely exists in healthy urethræ, should be noticed, and intercourse be avoided until it shall have ceased.
About this time is perceived a slight heat on passing water, or at the conclusion of the act; and shortly after, or may be before, a yellowish discharge is observed oozing from the mouth of the glans or nut of the penis; the symptoms then rapidly advance, unless timely and judicious means be adopted to palliate them or effect a cure; the scalding becomes intense, and the pain and smarting continue some time after each operation of passing water: the discharge becomes profuse and clots on the linen, and continues to ooze out with little intermission: the orifice of the urethra looks red and inflamed, and the glans itself swells and is occasionally extremely tender: the foreskin or prepuce sometimes, but fortunately not always, becomes swollen, and tightened over the nut of the penis, from which it can not be drawn back, constituting that form of the disease known by the name of phymosis. See drawing annexed.

When that is the case, other annoyances ensue; the purulent matter collects around the glans; excoriations, ulcerations, and sometimes warts, are the consequence; the whole symptoms become thereby much aggravated. It also happens that the prepuce from inflammation assumes a dropsical appearance, that is to say, the edges or point swell, and appear like a bladder filled with water; thus, the size which the penis then arrives at is enormous, and to the patient very alarming; it usually, however, subsides in a day or two, if rest and proper measures be employed.
