Motility of Human Spermatozoa after Migration in Bovine Serum Albumin
Isolation of motile spermatozoa has often been attempted for experimental purposes as well as in an effort to resolve certain problems of male hypofertility. A study by Ericsson et al. in 1973 on migration characteristics of spermatozoa in bovine serum albumin (BSA) solutions showed that it was possible not only to isolate a population which contains a majority of Y bearing spermatozoa but also to significantly increase the proportion of motile forms.1 These results were contested by Evans et al. and Schilling and Thormaèhlen who found no change in these parameters;2,3 and Ross et al. were able to determine only an augmentation of motile forms. 4 However, Ericsson’ s findings have been supported by Broer et al.5 and David et al.6,7 who both found a marked isolation of motile forms and Y bearing spermatozoa.
