Low sperm count
- Are in fertile because to few spermatozoa survive the female reproductive tract
- May reflect inflammation of the epididymis, ductus deferens, or prostate gland
Common abnormalities of sperm

The seminal glands 60%
Prostate gland 30%
The nurse cells and epididymis 5%
Bulbourethral glands less than 5%
Protease enzyme in seminal fluid
May help dissolve mucus in the vagina
Seminal plasmin enzyme in seminal fluid
Prostatic enzyme that kills a variety of bacteria, including Escherichia coli
A prostatic enzyme that coagulate the semen after ejaculation by
Converting fibrinogen to fibrin
Fibrinolysin
