Number of Spermatozoa for AI

During insemination, if the total motile sperm number is less than 5 million, the chance for pregnancy is lower than that of a higher sperm count. Generally we expect that we can separate and transfer 10-20 million normal spermatozoa or more from the original semen specimen in the uterus or at least 5 million sperm at the time of insemination process.
