EXPERIMENTALChildren faced with a fertility threatening diagnosis or treatment plan will be offered testicular tissue cryopreservation, particularly if pre-pubescent and without other options to preserve fertility.
Interventions
Eligibility Criteria
You may qualify if:
- Be male 0-17 years of age
- Meet at least one of the following four conditions:
- Be scheduled to undergo surgery, chemotherapy, drug treatment and/or radiation for the treatment or prevention of a medical condition or malignancy with risk of causing permanent and complete loss of subsequent testicular function. Risk categories based on treatment regimens are indicated below. Investigators will utilize three sources to calculate risk: 1. "Fertile Hope - Risks of Azoospermia" brochure that details typical agents and treatment regimens in each risk category, 2. The Summed Alkylating Agent dose score (Green et al., 2009) or 3. The Cyclophosphamide Equivalent Dose method (Green et al., 2014). Because of the complexity of many treatment regimens, patient risk categorization will be at the discretion of the investigators.
- High Risk
- \>= 80% risk of prolonged azoospermia, Fertile Hope Brochure
- Summed alkylating agent dose score \>= 3
- Cyclophosphamide equivalent dose \>= 7,500mg/m\^2
- Intermediate risk (21-79% risk of prolonged azoospermia, Fertile Hope)
- Low Risk ( =\< 20% risk of prolonged azoospermia, Fertile Hope)
- Eligibility is limited to patients in the High risk category and/or intermediate risk after discussion with pediatric oncology, fertility preservation team, and the patient/family
- Or, have a medical condition or malignancy that requires removal of all or part of one or both testicles
- Or, have a medical condition (genetic or autoimmune) that results in decline in fertility (e.g. Klinefelter syndrome)
- Or, have a newly diagnosed or recurrent disease affecting fertility. Those who were not enrolled at the time of initial diagnosis (i.e. patients with recurrent disease) are eligible if they have not previous received therapy that is viewed as likely to result in complete and permanent loss of testicular function
- Have two testicles if undergoing elective removal of a testicle for fertility preservation only. Note: removal of both testicles will limit fertility preservation options. Or have 1 testicle but limited potential for future fertility due to underlying condition, malignancy, prior surgery or previous torsion and no other fertility preservation methods are available except for testicular tissue cryopreservation
- Sign an approved informed consent and authorization permitting the release of personal health information. The patient and/or the patient's legally authorized guardian must acknowledge in writing that consent for specimen collection has been obtained, in accordance with institutional policies approved by the United States (U.S.) Department of Health and Human Services
- +3 more criteria
You may not qualify if:
- Diagnosed with psychological, psychiatric, or other conditions which prevent giving fully informed consent.
- Diagnosed with an underlying medical condition that significantly increases their risk of complications from anesthesia and surgery.
- Previous recipients of gonadotoxic chemotherapy or radiation therapy thought to have resulted in impairment of testicular function.
