[Sonographic monitoring of follicular maturation]

In recent years the interest for the evidence of ovulation and its follow-up has increased. This increase is especially evident in the field of out-body insemination. The ultrasound follow-up of ovulations is performed in the case of the growth of the follicle; determination of the ovulation ring; and observation of the Douglas free liquid. The authors present values of the follicular diameter on the 14th day of gestation in 34 patients with spontaneous, stimulated and induced cycles. In their opinion this procedure is a very useful method which, in addition to other parameters, enables a good inspection into the functioning of the ovary.
