Oligoasthenospermia is a combination of several sperm alterations:
- Low sperm count (oligospermia).
- Low sperm motility (asthenospermia).
Achieving a natural pregnancy with a diagnosis of oligoasternospermia will be more difficult, as the sperm will not always be able to reach the egg. The recommendation would be IVF treatment to assist fertilization.
The IVF-ICSI technique is usually recommended, as it significantly optimizes fertilization rates compared to classical IVF. However, in the case of oligoasternospermia, the ICSI technique will be used with all the more reason, since it will allow a better selection of motile spermatozoa.
Depending on the seminogram values, biologists may use an additional technique for sperm pre-selection, such as the PICSI or FertileChip techniques.
