ABSTRACT
Overian follicular diameter was measured using real time ultrasound in 21 hyperstimulated patients from April to September 1986. And we analyzed the relation between the size measured with ultrasonography and maturity observed under the phased microscopy, the correlation between aspirated dominant follicular volume and the dominant follicular volume calculated by the size measured with ultrasonography. Also we experienced the conditions which showed the ultrasonographic finding similar to that of follicle.
The results were as follows:
1. The mean follicular diameter increased in a linear fashion from 7 days after LMP (9.4mm+2.8)to the one day before ovum pick up(18.2+2.8).
2. The mean diameter of the most appropriate dominant follicle was 19.08+1.23mm
3. The correlation between the dominant follicular volume measured with ultrasonography and aspirated follicular volume during ovum pick up was highly significant(r=0.94;0<0.001).
4. during follicular growth and maturity monitoring the conditions which misdiagnosed of follicle were simple ovarian cyst(1 case), hydrosalpinx (1 case), endometriosis( 1 case), tubo-ovarian abscess(1 case), Hydatid of Morgagni(1 case).
