title: Live birth after transfer of vitrified-warmed blastocyst derived from ICSI with frozen-thawed sperm: case report.
abstract: OBJECTIVE
  A live birth after transfer of vitrified-warmed blastocyst derived from intracytoplasmic sperm injection (ICSI) with frozen-thawed sperm of a male cancer patient is described.
  
  
  METHODS
  A case report from a tertiary center for assisted reproductive technologies. The 35-year-old male patient had been diagnosed with testicular tumor nine years ago. He had unilateral orchiectomy operation after the diagnosis. Four years after the first operation, he was diagnosed with another testicular tumor in the other testis. He admitted to our center with the demand of sperm preservation before the second surgery. The sperm samples were cryopreserved and stored in liquid nitrogen until required. The patient had no chemotherapy or radiotherapy after the operations. After he completed his oncologic follow up, ICSI was decided with his frozen samples. Although the couple failed to conceive with the fresh cycle, the remaining embryos were frozen and revealed a pregnancy in the subsequent frozen-thawed cycle.
  
  
  RESULTS
  A healthy female infant with a birth weight of 3,700 g was born by cesarean section at 38th weeks of the gestation.
  
  
  CONCLUSIONS
  Giving detailed information about fertility-saving management in male patients is important in those who wish to bear children. However, both the patients and physicians should be cautious that preservation should be performed before surgery and/or adjuvant therapy. In this respect, assited reproductive technology (ART) and related facilities yield chance of pregnancy in such population.
