title: Ultrasonic assessment of ovulation in cyclofenil induced ovulatory cycles.
abstract: Graafian follicle growth was studied by ultrasound scanning during the peri-ovulatory period in 64 ovulatory cycles in 32 infertile patients on cyclofenil treatment, and compared with a control group of 32 patients with confirmed ovulatory cycles assessed on the basis of serum progesterone levels in the middle of the second half of the cycle. The mean maximum diameters of the leading follicles before ovulation were 21.9 +/- 0.6 (S.E.) mm and 24.4 +/- 0.5 (S.E.) mm, respectively for the cyclofenil group and the normal control group (P greater than 0.05). In 79% of the cyclofenil stimulated group and 83% of the spontaneous ovulation group, ultrasonic evidence of ovulation was present between 12 and 36 h after the initial increase in urine LH levels. Ultrasound scanning was found to be simple, and a quick method of monitoring graafian follicle development and ovulation on cyclofenil therapy and the cycles were comparable to the spontaneous ovulatory cycles as assessed on the basis of graafian follicle diameter, and the time of ovulation. Cervical score was not found to be useful to assess ovulation time in the cyclofenil treated group since 31.3% achieved a score of 10 or more on day -4, 93.8% within 24 h of ovulation and 24% on day 3 following the ovulation.
