Please note:
There is no absolute laboratory test or combinations of tests that will accurately predict the subsequent fertility of an ejaculate or a dose of semen.
- In other words we can not look at 2 samples of semen and accurately predict that sample A will result in a 92% farrowing rate and that sample B will result in an 85% farrowing rate.
- However, we should be able to distinguish between samples of obvious low quality, which if used for insemination, would result in very low or zero conceptions.
