OBJECTIVE: To report a case of transient ovarian failure shortly after arterial embolization for treatment of uterine fibroids, followed by recovery of ovarian function. DESIGN: Case report. SETTING: A university-based hospital. PATIENT: A 49-year-old woman with menorrhagia and anemia secondary to uterine fibroids and refractory to medical management. The follicle-stimulating hormone (FSH) level on cycle day 3 before the procedure was 8.2 mIU/mL. INTERVENTION(S): Bilateral uterine artery embolization for treatment of menorrhagia. MAIN OUTCOME MEASURE(S): Serum FSH level. RESULT(S): The patient developed amenorrhea and hot flashes 3 months after uterine artery embolization. Her serum FSH level at that time was 140.1 mIU/mL. Four months later, uterine bleeding resumed; her serum FSH level was 2.1 mIU/mL. CONCLUSION(S): Uterine artery embolization may hasten ovarian failure. This procedure should be reserved for women who have completed their child-bearing or are poor candidates for myomectomy. Patients should be counseled appropriately about the risk of possible ovarian failure.
To examine whether the duration of exclusive breastfeeding affects maternal nutrition or infant motor development, we examined data from two studies in Honduras: the first with 141 infants of low-income primiparous women and the second with 119 term, low birth weight infants. In both studies, infants were exclusively breastfed for 4 mo and then randomly assigned to continue exclusive breastfeeding (EBF) until 6 mo or to receive high-quality, hygienic solid foods (SF) in addition to breast milk between 4 and 6 mo. Maternal weight loss between 4 and 6 mo was significantly greater in the exclusive breastfeeding group (EBF) group than in the group(s) given solid foods (SF) in study 1 (-0.7 +/- 1.5 versus -0.1 +/- 1.7 kg, P < 0.05) but not in study 2. The estimated average additional nutritional burden of continuing to exclusively breastfeed until 6 mo was small, representing only 0.1-6.0% of the recommended dietary allowance for energy, vitamin A, calcium and iron. Women in the EBF group were more likely to be amenorrheic at 6 mo than women in the SF group, which conserves nutrients such as iron. In both studies, few women (10-11%) were thin (body mass index <19 kg/m(2)), so the additional weight loss in the EBF group in study 1 was unlikely to have been detrimental. Infants in the EBF group crawled sooner (both studies) and were more likely to be walking by 12 mo (study 1) than infants in the SF group. Taken together with our previous findings, these results indicate that the advantages of exclusive breastfeeding during this interval appear to outweigh any potential disadvantages in this setting.
BACKGROUND: The purpose of this article is to review the present knowledge about physical activity and reproductive health. METHODS: Medline and manual search for articles related to exercise and menstrual function, and exercise and pregnancy were performed. RESULTS: Repetitive intensive exercise with increased stress hormone utilisation seems to partly explain the disturbances in the hypothalamic-pituitary-adrenal axis. The prevalence of menstrual irregularities is higher among athletes who participate in sports in which leanness is considered important for performance. Most of the studies concerning exercise-induced amenorrhoea have focused on low body weight and low fat ratio of body weight. However, energy drain and nutrient deficiency have been found to be important variables explaining menstrual irregularity in athletes. Loss of bone mass is related to menstrual irregularities hence it is important that menstrual irregularity not is considered a "normal" aspect of being an athlete. There are a number of positive effects and a few hypothetical risks related to exercise during pregnancy. There are no clinically controlled studies allowing us to draw conclusions about the effect of intensive training during pregnancy. INTERPRETATION: Physically active women should be aware of the importance of sufficient energy intake to keep their regular menstrual cycle. Moderate exercise during pregnancy is recommended.
