What are the differences between the REM and the semenogram?

By Zaira Salvador B.Sc., M.Sc. (embryologist).
Last Update: 05/17/2022

In a normal semen analysis, the quality of the semen is analyzed without it having undergone any sperm capacitation process. We simply study different semen parameters (motility, morphology, concentration, volume, etc.) after obtaining the fresh sample by ejaculation.

If in addition to this study, we perform the recovery of motile spermatozoa after having capacitated the seminal sample, we speak of seminogram + REM or simply REM test.
