As we have already seen after ejaculation prostate fluid serves to nourish and propel spermatozoi towards the egg. If the prostate fluid is abnormal or contains blood because of inflammation the spermatozoa may lose mobility (astenospermia) or even become completely immobile and have a shortened life-span. When the Chalmydia Tracomatis is present they will be markedly deformed. If the ejaculatory ducts are also inflamed due to direct obstruction or to pressure exerted by surrounding prostate tissue the sperm will contain fewer spermatozoa (oligospermia) and will be ejaculated with little force into the vagina. Difficulties will ensue in trying to overcome the barrier of the female cervical mucous.
If the seminal vesicles are infected symptoms will be more severe and more evident.
