    Advances in Assisted Reproductive Technologies pp Cite as. Mammalian spermatozoa possess a unique topography which clearly defines the location of the various organelles responsible for the diverse functions the sperm cell must fulfill, before and during fertilization. A technique of in depth evaluation of sperm morphology might afford a wide spectrum of information, ranging from data concerning the integrity of the spermatogenetic process of the testes to the functional properties of the spermatozoa.

    Sperm concentration, morphology, DNA condensation and nuclear protein pattern as well as sperm adenylate cyclase were evaluated in semen samples provided by 7 volunteers every 8 h for 2 days. During the observation period, sperm concentration and total sperm number decreased but began to return towards normal after a 3-day abstinence period. No increase in the proportion of immature sperm cells was observed by light microscopy. Total adenylate cyclase EC 4. Microflow fluorometry revealed no consistent alterations in the DNA or nuclear protein distribution.
