Renovation works Brussels IVF

To increase the comfort and privacy of its patients, Brussels IVF is renovating its nursing unit (VP03). The end of the renovation works is scheduled mid-March 2024.
The preparation for every intervention where an admission is needed (follicle puncture, surgery, …) and follow-up care will temporarily be carried out in another nursing unit at UZ Brussel.

For the same reason, your partner or companion can not be present during your stay.
