[Ultrasonic follow-up check of overstimulation by gonadotrophin therapy (author's transl)]

The risk of overstimulation is implied in any therapy, using gonadotrophin to induce ovulation. Cystic changes were recorded from the ovaries in 30 of 119 gonadotrophin treatments. Early detection of overstimulation was accomplished by ultrasonic follow-up checks and daily oestradiol assay.
