Monitoring of HMG-stimulated follicular development by real-time ultrasound.

Monitoring of human follicular development by real-time ultrasound during HMG-HCG treatment is presented. With the aid of ultrasound monitoring, the ovulation rate is raised to 94.3% (formerly 80% without ultrasound). Serious side effects such as ascites and/or hydrothorax did not occur in this study (1.2% without ultrasound controls). The pregnancy rate was 21/47 (44%) of all hormonally treated patients. By means of real-time sector scan examination, the growing follicle could be detected in 103/106 (97.3%) of HMG-HCG treated cycles. Thus real-time ultrasound examinations provide results comparable to those achieved mostly by time-consuming compound scan in demonstration of the growing follicle.
