Matching criteria: closest-age, same-sex biologic sibling.
Statistically significant differences between groups.
Participants sought fertility assistance by consulting a doctor or taking fertility-promoting medications.
High-intensity conditioning = myeloablative intensity conditioning; low intensity conditioning = nonmyeloablative/reduced-intensity conditioning.
