Presence of Donor-Derived DNA in Semen Samples From Cancer Survivors Who Underwent Donor Stem Cell Transplant
RATIONALE: Studying samples of semen from cancer survivors in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
PURPOSE: This phase I research study is looking at the presence of donor-derived DNA in semen samples form cancer survivors who underwent donor stem cell transplant.
Chronic Myeloproliferative Disorders
Multiple Myeloma and Plasma Cell Neoplasm
Testicular Germ Cell Tumor
Genetic: DNA analysis
Genetic: polymerase chain reaction
Other: flow cytometry

|Official Title:||Detection of Donor-Derived DNA in Semen Samples Among Recipients of Allogeneic Hematopoietic Stem-Cell Transplants|
- Presence of donor-derived DNA in semen samples of male survivors of allogeneic hematopoietic stem cell transplantation [ Time Frame: end of study ] [ Designated as safety issue: No ]
Biospecimen Retention: Samples With DNA
Your sample will only be used for research at Vanderbilt University and will not be sold. Health insurance companies and group health plans may not request your genetic information that comes from this research. As part of this study, we ask that the data from the semen analysis can be put into a databank at Vanderbilt and kept with data from other people in the study. Your data will be given a special code and will not identify you directly. We ask you to select yes or no to allow/disallow us to:
- Use your semen sample for gene research.
- Store/share your semen sample for future gene research in hematopoietic stem cell transplantation.
- Store/share your semen sample for future gene research for other health problems (such as cancer, heart disease, etc).

Laboratory biomarker analysis will be performed on the samples collected.
- To examine semen samples from male survivors of allogeneic hematopoietic stem cell transplantation for the presence of donor-derived DNA.
OUTLINE: Semen samples are collected and assessed by flow cytometry and PCR. DNA samples are compared to previously analyzed DNA extracted from survivor and donor. Samples are also analyzed for sperm concentration, motility, morphology, and viability.
