A study was conducted which compared transvaginal and transabdominal u
ltrasound in determining the prevalence of polycystic ovaries in a pop
ulation of women. Women, chosen randomly from electoral rolls, were se
nt a letter inviting them to take part in a study determing the presen
ce of polycystic ovaries. A transvaginal and transabdominal ultrasound
scan was performed on day 5-9 of their menstrual cycles. A total of 1
87 women (mean age 33 years) took part in the study. The prevalence of
polycystic ovaries was 21% (40/187) by transabdominal ultrasound and
27% (36/134) by transvaginal ultrasound. No differences existed betwee
n women with polycystic and normal ovaries with respect to uterine siz
e and endometrial thickness. Mean ovarian volume was larger in women w
ith polycystic ovaries irrespective of the use of hormonal contracepti
on or breast feeding. There was no difference in the prevalence of pol
ycystic ovaries diagnosed by transabdominal or transvaginal ultrasound
in the group of randomly selected women. However, almost 20% of the w
omen declined a transvaginal ultrasound examination.
