Abstract:
OBJECTIVE:To investigate the health safety of the offspring delivered following natural pregnancy after orthotopic fetal ovarian allotransplantation in rats.
METHODS:Any symptoms of spontaneous abortion during pregnancy and of any possible still birth and death of infant rats within 3 days after the delivery were observed and compared in 19 pregnant rats (the study group) after the orthotopic fetal ovarian allotransplantation and in another 10 pregnant rats (the control group). Forty offspring rats from each group were selected randomly. The mean weight at day 35 after the birth of offsprings was measured and compared. By routine G-banding technique, the karyotype was analyzed and the chromosomal number and structure were observed.
RESULTS:There was no spontaneous abortion, still birth, or death in the infants within 3 days after the birth in both groups. The body weight of offsprings at 35 days in both groups was (93.80 ± 4.93) g and (94.13 ± 4.53) g, respectively. There was no significant difference between the 2 groups (P> 0.05). The karyotype analysis indicated that the karyotype from both offspring groups was 42, XX or 42, XY. No chromosome abnormality (abnormal chromosomal number or abnormal chromosomal structure) was observed in both groups.
CONCLUSION:The health status of the offsprings of rats after orthotopic fetal ovarian allotransplantation is safe.
