RESUMO
Follicular development was followed by echography during 18 menstrual cycles in 10 women volunteers. Results were correlated with changes in serum hormone levels, basal body temperature curves, and cervical mucus changes. The average follicular growth as measured from the time of echographic visualization was 0.3 cm/day. The diameter of the follicle measured the day before disappearance was 2.7 +/- 0.3 cm. In all cases echography was shown to indicate accurately the time of ovulation. Given its inoffensive nature, the usefulness of echography in determining the physical event of ovulation is demonstrated. Possible applications in the surveillance of ovulation induction methods and in artificial insemination are discussed.
PIP: Echography of the ovarian follicle was compared with indirect tests of ovulation detection, such as basal body temperature, serum hormone levels, and cervical mucus changes, to analyze its effectiveness as an ovulation detection device. Follicular maturation was studied in 10 normal women volunteers, aged 24-28 years, with regular menstrual cycles and not taking oral contraceptives. In all, 18 cycles were studied. Average follicular growth by echographic visualization was .3 cm/day; the diameter of the follicle the day before disappearance was 2.7+ or -.3 cm. The echographic report in all ways correlated with other ovulation detection methods, and since it is noninvasive and unoffensive, the use of echography for ovulation surveillance in particular cases, such as artificial insemination and ovulation induction experiments, is recommended.

The authors, who practised for years in Africa, present the present view on the effects haemoglobinopathies have on pregnancy and on modern therapeutic methods. They point out that among these haemoglobinopathies by far the most serious is haemoglobin SS or heterozygote S associated with haemoglobin C or with betathalassaemia. On the other hand, pregnancies in patients with the sickle-cell trait (HbSA) are often very well tolerated.
