Abstract:
:A new sperm isolation technique was studied in conjunction with the short-term freeze preservation of human spermatozoa. The isolation procedure yielded subpopulations of spermatozoa with very high percentage motility and progressive motility score, and which were virtually free of seminal debris. For 24 semen samples from 13 donors, the mean prefreeze values of percentage motility and motility score were 53% (2.8), 73% (3.1), and 88% (3.5) for the parent semen, 7.5% BSA (middle) fractions, and 17.5% BSA (bottom) fractions, respectively. These samples were used without a priori constraint on semen quality. Eleven samples were preselected on the basis of good motility in the semen. These yielded prefreeze motility values of 66% (3.2), 70% (3.4), and 87% (3.9) for the semen and two fractions, respectively. Sperm motility in the middle fractions was thus intermediate to that in the semen and in the bottom fractions, although closer to the former in these 11 cases. The sperm freeze preservation procedure involved dilution of the semen samples and separated sperm fractions with a cryoprotective semen extender, and freezing and thawing in a conventional manner. Post-thaw percentage motility, motility score, and percentage survival were substantially higher for the separated fractions than for the parent semen. For the 24 cases, the bottom fractions yielded mean values of 57% motility, 3.0 motility score, and 70% survival, in comparison with the respective values of 20%, 2.3, and 34% for the semen. In the 11 preselected cases, the bottom fractions yielded post-thaw mean values of 60% motility, 3.3 motility score, and 72% survival; the middle fractions yielded respective values of 45%, 3.1, and 64%; and the parent semen yielded respective values of 27%, 2.3, and 41%. It was concluded that the major factor in improving post-thaw motility recovery was the separation process as a whole, rather than the degree of separation.
