[Ovulation induction with gonadotropins aided by cervix mucus analysis and echography].

Induction of ovulation was performed in 148 cycles using human menopausal gonadotropins (HMG) in 52 patients, seven with hypothalamic-pituitary failure and 45 suffering dysfunction at this level. Several induction schemes were used beginning on the second day of the cycle, until one or more follicles larger than 14 mm were found, to administrate 10,000 UI of human chorionic gonadotropin (HCG). Clinical valuation of cervical mucus and ultrasound of the ovaries to assess follicular development were done, from day eight of the cycle. Twenty five pregnancies resulted in 23 patients (44%), three in patients with failure and 22 in the dysfunction group. A total of 19 healthy babies were taken home, however three neonatal deaths, four miscarriages and one ectopic pregnancy occurred. Multiple gestation was present in three patients (12%), one was quadruplet, one triplet and one twin. The ovarian hyperstimulation syndrome (OHS) was detected in seven patients (13.4%), three were mild, two moderate and two severe; two cases of OHS had multiple pregnancies. Although induction of ovulation with HMG in patients with anovulation is a complex procedure requiring strict clinical vigilance and advanced technological resources, in this clinical study it was possible to obtain similar results to other series, using high resolution ultrasound only, without daily measurements of hormones.
