Emergency Fertility Preservation in a Young Woman With Non-Hodgkin Lymphoma

A nulliparous woman, age 25 years, had received a diagnosis of non-Hodgkin lymphoma (NHL) and now presented with stage IIA diffuse large B-cell lymphoma (DLBCL). According to her hematological oncologist's treatment plan, chemotherapy had to start immediately (within 1 week), with the patient receiving 6 courses of the standard R-CHOEP21 regimen (rituximab 375 mg/m², cyclophosphamide 750 mg/m², hydroxydaunorubicin 50 mg/m², vincristine 1.4 mg/m², etoposide 100 mg/m², prednisone 40 mg/m²). Due to potential risks of chemotherapy-induced gonadotoxicity and subsequent iatrogenic premature ovarian failure (POF) and fertility loss, the patient was referred to the reproductive medicine department for fertility preservation counseling and further management.
