Impact of Intensified Chemoimmunotherapy Regimens in Aggressive Non‐Hodgkin Lymphoma on Reproduction Patterns

European Journal of Haematology, EarlyView.
ABSTRACT Concerns about treatment‐related fertility impairment are common among young adult lymphoma survivors. Evidence on the impact of treatment for aggressive non‐Hodgkin lymphoma (NHL) on future childbearing is limited, although many individuals of reproductive age are affected.

Company‐Sponsored Fertility Benefits: A Gift‐Exchange and Contextual Intersectionality Informed “FAiRE” Framework Guiding Design and Implementation

Gender, Work &Organization, EarlyView.
ABSTRACT Managing the work‐fertility interface is a major challenge for organizations when implementing fertility policies. These policies cover a broad spectrum of areas including clinical treatments, preservation and storage of eggs and sperm, preimplantation and diagnostics, and non‐clinical family‐building assistance. They also differ from standard
