Pregnancy after 20 Years

- Successful Pregnancy 20 Years After Cryopreservation -

 

Recently, the Tyler Medical Clinic and Westwood Cryobank achieved the first successful pregnancy using sperm that was cryopreserved for approximately 20 years. 

In 1978, a 32-year-old man came to the Tyler Medical Clinic to deposit sperm for cryopreservation.  In mid-1997 he informed us that he had relocated out of state and that he and his wife were thinking about the possibility of starting a family.   

Because of prolonged storage and the limited number of vials, a decision was made to proceed with GIFT or IVF/ICSI.  The wife was given a schedule of medication and was instructed to return to California on day 11 of her menstrual cycle.  Her response was satisfactory, and the GIFT procedure was performed on day 13.  The semen, after thawing, showed 24% active motility.  Five oocytes (three mature and two slightly immature) were  retrieved and transferred, with the husband's sperm, into the fallopian tube.   

The patient returned to the East Coast two days after the procedure.  A pregnancy test was positive on day 25.  Ultrasound at six weeks confirmed a twin intrauterine pregnancy.  The course of gestation was uneventful, and female twins were delivered at 39 weeks without complications.
