[New fluorescence method for staining of human spermatozoa]
Abstract:
300 human ejaculates from a andrological group of patients were stained for visualisation of the spermatozoal morphology with the new fluorochrome DAPI (4',6-diamidino-2-phenylindol) and examined by fluorescence microscopy. DAPI has proven to be stable, since the preparations do not fade even after long storage periods. It can be utilized in small amounts and has a special affinity for the spermatozoon nucleus, which it stains light yellow, in contrast to the acrosomal parts which are fluorescent green. The method is surprisingly simple and can be carried out in a few minutes. A further advantage of the DAPI procedure lies in the additional staining of leucocytes and microorganisms, so that inflammatory processes of the male accessory organs can be diagnosed as well.

- Traditional staining methods can be time-consuming and lack specificity.
Purpose:
- To evaluate the efficacy of 4',6-diamidino-2-phenylindol (DAPI) as a fluorochrome for assessing human spermatozoal morphology.
- To determine the utility of DAPI staining in diagnosing inflammatory processes in male accessory organs.
Summary:
- A novel fluorescence microscopy method utilizing DAPI was developed for human ejaculates.
- DAPI stains spermatozoon nuclei light yellow and acrosomal parts green, offering clear visualization.
- The technique is rapid, stable, and also stains leukocytes and microorganisms, aiding in diagnosing inflammation.
