PEEMIA Is the form of male sterility where, with well-preserved capacityof coition and normal ejaculation, the liquid contains no sperma-tozoids. Causes.—1. This form occurs in robust young men with normaltesticles, without any previous disease, without demonstrable cause. 2. It occurs quite frequently in retention of the testes, or wherethey have been arrested in their development. 3. In parenchymatous disease of the substance of the testicles,as well as in neoplasms which lead to atrophy. 4. In obliteration of the seminal ducts, principally the result ofgonorrhoea! epididymitis. Liegois found but eight in eighty-threecases of double gonorrhoeal epididymitis that did not become defi-nitely sterile. 5. General diseases may, by weakening the organism, cause theabsence of spermatozoa; thus Levin found but ten times spemia-tozoids in persons who had died from tuberculosis. We may findtemporary azoospermia of this character in healthy individuals whoare suffering from excesses. PLATE 66

The practical side of this question is important. The physiciandoes not always receive the urine fresh for examination, and occa-sionally may not have time for it immediately. The question thenis: how long it is possible to examine the urine for semen. Myinvestigations have shown that spermatozoids may be distinctly de-monstrated after six weeks, while, according to the usual notions,they should be dissolved in the urine in a few days. Donne claims even to have demonstrated spermatozoids afterthree months in putrid urine. Spermatozoids, it may at once be remarked, show great resist-ance against external influences. They are dissolved with difficultyby concentrated mineral acids and acetic acid, by liquor ammonise,potassae, or sodse; they are stained yellow by sulphuric and nitricacid. They are destroyed most easily b
