Ist der erfolg einer sterilitätsbehandlung mit intrazytoplasmatischer spermieninjektion bei einseitig ovarektomierten frauen von der lage des verbliebenen ovars abhängig?

Background. Single ovary women compose a group of special interest in assisted reproduction technologies. The aim of the present study was to investigate whether the outcome of the infertility treatment with intracytoplasmatic sperm injection (ICSI) in women with a single ovary was affected by the location of the ovary. Methods. 60 cycles from 24 women, which were stimulated with either human menopausal gonadotrophin (hMG) or recombinant follicle stimulating hormone (rFSH) and a gonadotrophin releasing hormone- (GnRH-) agonist, were retrospectively studied. 12 women had right and 12 had left ovary. Results. No statistical significant difference was found between the two groups regarding the days of stimulation, the peak estradiol levels, the number of aspirated follicles, the number of retrieved oocytes, the fertilization rate and the number of transferred embryos. The cumulative embryo score (CES) was also similar in both groups. Six pregnancies in the group with a right ovary and seven in the group with a left ovary were achieved. Conclusion. According to these results, right and left ovary in single ovary women under external stimulation are equally active and potent for reproduction.
