Objective: To describe the birth achieved from frozen embryos after
intracytoplasmic sperm injection (ICSI) of donor sperm into vitrified
oocytes.
Patient: A 25-year-old woman whose husband was azoospermic undergoing
IVF therapy.
Methods: Oocytes collected after ovarian stimulation were vitrified,
thawed, and fertilized by frozen donor sperm.
Results: Nineteen oocytes were vitrified and all survived after
thawing. Thirteen of the 19 oocytes that underwent ICSI with donors
sperm were successfully fertilized. Twelve embryos were cryopreserved
again by conventional slow-freezing protocol because of uterine
bleeding on the day of transfer. Three thawed embryos were
transferred, and a normal male with an infant karyotype of 46,XY was
delivered.
Conclusion: This case report demonstrates effective oocyte
cryopreservation by vitrification. |
