TREATMENT TIMING NOTICE: Fertility preservation interventions (egg retrieval, ovarian tissue banking, sperm freezing) must be carefully synchronized with your oncologist so that curative cancer therapy is never delayed beyond medically safe intervals.

1. Educational & Supportive Scope Only

The content provided on OncoFertilityGuides (accessible at fertility.oncoguides.org and across the OncoGuides Network) is published solely for educational, research, and supportive purposes. The information, interactive CED calculators, random-start stimulation calendars, POSITIVE trial protocols, and charitable grant directories are designed to support, not replace, the clinical judgment of a board-certified reproductive endocrinologist or medical oncologist.

2. No Doctor-Patient Relationship

Use of this website, including calculating Cyclophosphamide Equivalent Doses or checking POSITIVE protocol eligibility, does not establish a doctor-patient relationship, clinical consultation, or medical prescription. You should never initiate ovarian stimulation or pause prescribed adjuvant endocrine therapy without explicit medical oncology authorization.

3. Teratogenicity & Conception Safety

Patients taking tamoxifen, aromatase inhibitors, or undergoing systemic chemotherapy must observe strict contraception and medically approved washout periods before attempting pregnancy.
