Improved cryopreserved semen fecundability in an alternating fresh-frozen artificial insemination program.
This study with glycerol and increased number of motile sperm inseminated showed an increase in f to 10.4% for frozen semen and 27.4% for fresh semen. There is a significant (P less than 0.01) difference in pregnancy rate when greater than 100 million motile sperm are inseminated (31.3%) than when less than that number are inseminated (11.9%) in the first cycle when frozen semen is used.
