Raw and test-thaw semen parameters after cryopreservation among men with newly diagnosed cancer.

Objective: To characterize sperm parameters from thawed semen samples of men with different cancers who cryopreserved semen before oncologic therapy.

Design: Retrospective cohort study.

Setting: Tertiary academic medical center.

Recovery, isolation, identification, and preparation of spermatozoa from human testis.

In some cases, human spermatozoa to be used for in vitro fertilization are processed from testicular or epididymal biopsies collected in the clinic or operating room. An appropriately equipped Andrology or Embryology Laboratory is required. Sterility must be maintained at all stages from collection and transport to identification and processing to insemination or cryopreservation.
