Effect of ultrasound monitoring of follicular growth on the conception rate: a clinical study

Periovulatory ultrasonography (POUS) was performed on 59 anovulatory women over 523 treatment cycles. Follicular development was stimulated with either clomiphen citrate (CC) or human menopausal gonadotropin (hMG). Thirty-one pregnancies were induced; 23 went to term. Three factors were considered in evaluating the incidence of conception: the patient's age, drug use and the presence or absence of POUS
