Microfluidic chip vs standard sperm prep for IVF with embryo testing
This study compares two ways of preparing sperm for IVF when you are also doing genetic testing of embryos (PGT-A). One method uses a microfluidic chip, and the other is the standard spinning technique. The goal is to see which method leads to better embryo development.
Abu Dhabi, Abu Dhabi EmirateAges Any age - NCT07270250Recruiting
Do dry or humid culture conditions affect embryo health?
This trial tests whether growing embryos in dry or humid conditions affects their development and genetic health. It may help improve the success of IVF with genetic testing.

Stem cell transplant for children with sickle cell and ABO mismatch
This trial studies a stem cell transplant approach for children with sickle cell disease, using a sibling donor whose blood type is not compatible. It aims to see if this transplant method can safely reduce serious sickle cell complications.
Calgary, AlbertaAges 1–19 - NCT03587272RecruitingPhase 2
Sibling bone marrow transplant to reduce treatment side effects
This study tests a way to do a bone marrow (stem cell) transplant from an HLA-matched sibling in children with sickle cell disease, aiming to lower the risk of serious side effects. You may be considered if you have certain past sickle complications and your body can safely handle the transplant plan.
