[Lactation and amenorrhea in women from the rural and urban areas of Yucatan].
Influence of environment and lactation patterns on amenorrhea duration and frequency of ovulation before the first menstrual bleeding postpartum are studied on a group of 100 women (half rural, half from urban areas). All subjects studied were highly motivated to breastfeed for prolonged periods. Results show a more prolonged amenorrhea, although not statistically significant, in those women from the rural zone. Ovulation frequency before the first vaginal bleeding was 14% none ovulated before six months.
