Types of samples
Institut Marques provides frozen sperm samples from donors in two formats:
- Standard format (not processed) These samples (before being used for one cycle of IVF or IUI) should be processed by the means of density gradients, wash and spin, etc. depending what the centre deems appropriate.
- IUI-Ready format (processed) These samples do not need to be processed before being used for an IUI. They can be used directly after thawing.
When using IUI-ready samples for IVF cycles, Institut Marques recommends carrying out a wash with growth medium before ICSI or eggs insemination.
Quality and safety controls
All laboratory processes are controlled and monitored by a second biologist, who certifies the safety and traceability of these processes any time.
Twice a year, Institut Marquès Laboratory participates in an external quality control conducted by the United Kingdom National External Quality Assessment Service.
