Abstract
OBJECTIVE
To investigate the feasibility of using late spermatids in intracytoplasmic sperm injection (ICSI) for patients in which there is a total lack of normal and testicular sperm.
DESIGN
Clinical study.
SETTING
Private fertility center with adjacent laboratory facilities.
PATIENT(S)
Thirty-six males diagnosed with azoospermia underwent testicular biopsy and the resulting spermatids from nine patients were used to fertilize oocytes retrieved from their respective wives by ICSI.
INTERVENTION(S)
Intracytoplasmic spermatid injection of oocytes with late spermatids obtained by testicular biopsy.
MAIN OUTCOME MEASURE(S)
Fertilization, pregnancy, and delivery rates.
RESULT(S)
Three of the cases resulted in pregnancies with childbirth occurring in all three, identical twins in one, and individual singletons in the other two cases.
CONCLUSION(S)
It is possible to achieve successful levels of pregnancy and childbirth in cases of azoospermia by intracytoplasmic injection of late spermatids.
