[The biochemistry of sperm].

[Article in French]



Human ejaculate is composed of about 0.2 ml. of spermatozoa and seminal plasma. It is possible to analyze it after collection by masturbation. Sperm components come from prostatis secretion (acid phosphates, magnesium, zinc, citric acid), and from the seminal vesicules (fructose). Several studies are ongoing to define the compotents of seminal plasma, such as proteins, prostglandins, amoniacids, and sex hormones, the latter very important since oligospermia is characterized by diminishing levels of estradiol and progesterone. Different tests are used to sear ch for autoantibodies, such as agglutinins, and for antibodies in the seminal plasma.
