A comparison of the ovarian response to external stimulation between women with right or left ovary participating in programs of ICSI/ET.
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 response to external stimulation and the outcome in women with a single ovary was affected by the location of the ovary.


METHODS
Sixty cycles from 24 women, which stimulated with either hMG or rFSH and a GnRH agonist, were retrospectively studied. Twelve women had right and 12 had left ovary. In all cases, the fertilization was performed by intracytoplasmic sperm injection.


RESULTS
There was not found any statistical significant difference 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 of the right ovary and seven in the group of left ovary were achieved.


CONCLUSIONS
According to these results, right and left ovary, in single ovary women under external stimulation, are equally active and potent for reproduction.
