RESUMEN

Arrested caudal extension of the fused Müllerian ducts, either complete or segmental, causes obstruction of the outflow tract. We describe a case of agenesis of the uterine isthmus and the procedure to establish the continuity of the outflow tract. A 15-year-old girl with cyclic pelvic pain and amenorrhea was found to have a 3-cm gap between the uterine body and the cervix. After cervico-uterine anastomosis via laparotomy she menstruated normally and was pain-free. Selected cases of arrested Müllerian duct extension can be corrected by primary anastomosis, which establishes anatomical continuity and restores menstruation and, possibly, future fertility.

RESUMEN

Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disorder in women with components of significant genetic predisposition and possibly multiple, but not yet clearly defined, triggers. This disorder shares several clinical features with hemochromatosis, a genetically defined inheritable disorder of iron overload, which includes insulin resistance, increased adiposity, diabetes, fatty liver, infertility, and hyperandrogenism. A notable difference between the two disorders, however, is that the clinical symptoms in PCOS appear at much younger age whereas they become evident in hemochromatosis at a much later age. Nonetheless, noticeable accumulation of excess iron in the body is a common finding in both disorders even at adolescence. Hepcidin, the iron-regulatory hormone secreted by the liver, is reduced in both disorders and consequently increases intestinal iron absorption. Recent studies have shown that gut bacteria play a critical role in the control of iron absorption in the intestine. As dysbiosis is a common finding between PCOS and hemochromatosis, changes in bacterial composition in the gut may represent another cause for iron overload in both diseases via increased iron absorption. This raises the possibility that strategies to prevent accumulation of excess iron with iron chelators and/or probiotics may have therapeutic potential in the management of polycystic ovary syndrome.

RESUMEN

CONTEXT: Polycystic ovary syndrome (PCOS) is a reproductive disorder of ovarian hyperandrogenism and insulin resistance characterized by abnormal luteinization of small follicles. After exposure to GnRH analog/FSH stimulation for in vitro fertilization (IVF), however, it is unclear whether such PCOS follicles remain abnormally luteinized during the resumption of oocyte maturation in vivo. OBJECTIVE: The aim of this study was to determine whether PCOS follicles exposed to GnRH analog/FSH stimulation for IVF show abnormal luteinization. DESIGN: This study was a prospective cohort. SETTING: The setting was an institutional practice. PATIENTS: Eleven PCOS and 30 normoandrogenic ovulatory women were included. INTERVENTION(S): All subjects received GnRH analog/FSH therapy after basal serum hormone determinations. MAIN OUTCOME MEASURE(S): Follicle fluid aspirated at oocyte retrieval from the first follicle of each ovary was assayed for gonadotropins, steroids, insulin, and glucose. LH receptor mRNA expression was determined in granulosa cells of the same follicle. RESULTS: In PCOS patients with basal hyperandrogenemia and hyperinsulinemia, total oocyte number was increased and follicle diameter was decreased, despite normal maximal serum estradiol levels. Within PCOS follicles, progesterone levels were reduced (P < 0.01), despite comparable bioactive LH and insulin levels and granulosa cell LH receptor mRNA expression; estradiol levels were normal, despite diminished FSH availability (P < 0.004). Elevated androstenedione (P < 0.01), testosterone (P < 0.001), and glucose (P < 0.01) levels also occurred. In PCOS follicles containing mature oocytes, however, elevated androgen levels were accompanied by both normal progesterone concentrations and a normal inverse relationship between glucose depletion and lactate accumulation. CONCLUSION: Hyperandrogenic follicles with mature oocytes from PCOS women receiving GnRH analog/recombinant human FSH therapy for IVF show sufficient glucose utilization for normal luteinization.

RESUMEN

In this review, we summarize existing research on a variety of environmental factors potentially involved in the etiology, prevalence, and modulation of polycystic ovary syndrome (PCOS), and we suggest avenues for future research. The main environmental factors we consider include environmental toxins, diet and nutrition, socioeconomic status, and geography. There is some evidence that environmental toxins play a role in disrupting reproductive health, but there is limited research as to how these toxins may affect the development of PCOS. Although research has also shown that PCOS symptoms are reduced with certain dietary supplements and with weight loss among obese women, additional research is needed to compare various approaches to weight loss, as well as nutritional factors that may play a role in preventing or mitigating the development of PCOS. Limited studies indicate some association of low socioeconomic status with certain PCOS phenotypes, and future research should consider socioeconomic conditions during childhood or adolescence that may be more relevant to the developmental onset of PCOS. Finally, the limited scope of comparable international studies on PCOS needs to be addressed, because global patterns of PCOS are potentially valuable indicators of cultural, environmental, and genetic factors that may contribute to excess risk in certain regions of the world.

RESUMEN

BACKGROUND: Polycystic Ovary Syndrome (PCOS) affects approximately 15% of reproductive-age women and increases risk of insulin resistance, type 2 diabetes mellitus, cardiovascular disease, cancer and infertility. Hyperinsulinemia is believed to contribute to or worsen all of these conditions, and increases androgens in women with PCOS. Carbohydrates are the main stimulators of insulin release, but research shows that dairy products and starches elicit greater postprandial insulin secretion than non-starchy vegetables and fruits. The purpose of this study was to determine whether an 8-week low-starch/low-dairy diet results in weight loss, increased insulin sensitivity, and reduced testosterone in women with PCOS. METHODS: Prospective 8-week dietary intervention using an ad libitum low starch/low dairy diet in 24 overweight and obese women (BMI ≥ 25 kg/m2 and ≤ 45 kg/m2) with PCOS. Diagnosis of PCOS was based on the Rotterdam criteria. Weight, BMI, Waist Circumference (WC), Waist-to-Height Ratio (WHtR), fasting and 2-hour glucose and insulin, homeostasis model assessment of Insulin Resistance (HOMA-IR), HbA1c, total and free testosterone, and Ferriman-Gallwey scores were measured before and after the 8-week intervention. RESULTS: There was a reduction in weight (-8.61 ± 2.34 kg, p<0.001), BMI (-3.25 ± 0.88 kg/m2, p<0.001), WC (-8.4 ± 3.1 cm, p<0.001), WHtR (-0.05 ± 0.02 inches, p<0.001), fasting insulin (-17.0 ± 13.6 µg/mL, p<0.001) and 2-hour insulin (-82.8 ± 177.7 µg/mL, p=0.03), and HOMA-IR (-1.9 ± 1.2, p<0.001) after diet intervention. Total testosterone (-10.0 ± 17.0 ng/dL, p=0.008), free testosterone (-1.8 pg/dL, p=0.043) and Ferriman-Gallwey scores (-2.1 ± 2.7 points (p=0.001) were also reduced from pre- to post-intervention. CONCLUSION: An 8-week low-starch/low-dairy diet resulted in weight loss, improved insulin sensitivity and reduced testosterone in women with PCOS.

RESUMEN

Insulin action is mediated by two insulin receptor (IR) isoforms, differing in mitogenic and metabolic function. IR isoform expression might occur in human granulosa cells and could be altered in polycystic ovary syndrome (PCOS) from hyperinsulinemia. To determine the relationship between granulosa cell IR isoform expression and follicular fluid insulin concentration in individual follicles, 18 normal women and seven PCOS patients receiving gonadotropins for in vitro fertilization were studied. Glucose tolerance testing was performed before pituitary desensitization, and fasting serum insulin was measured at oocyte retrieval. Granulosa cells and fluid aspirated from the first follicle were used to determine IR isoform mRNA expression and insulin concentration, respectively. IR isoform A mRNA expression was greater than that of IR isoform B expression in normal mural granulosa and cumulus cells, without a cell type effect. Intrafollicular insulin levels increased with adiposity and serum insulin levels at oocyte-retrieval but did not predict IR mRNA expression. Total IR mRNA expression, but not intrafollicular insulin levels, was elevated in PCOS patients, whereas intrafollicular insulin levels were increased in women with impaired glucose tolerance. Granulosa cell IR heterogeneity, together with adiposity-dependent intrafollicular insulin availability, introduces a novel mechanism by which insulin may affect granulosa cell function within the follicle.

RESUMEN

OBJECTIVE: To report the occurrence and management of pulmonary compromise, marked leukocytosis, and eosinophilia in a patient receiving P-in-oil after IVF and embryo transfer. DESIGN: Case report.A tertiary referral reproductive medicine unit. PATIENT(S): A 29-year-old patient receiving P-in-oil supplementation after IVF embryo transfer. INTERVENTION(S): Extensive diagnostic testing and surveillance for hypersensitivity to P in sesame oil; development of an alternative oil-based P-in-oil suspension. MAIN OUTCOME MEASURE(S): Tolerance of alternative P vehicle; clinical pregnancy. RESULT(S): The patient tolerated an alternative P oil vehicle and successfully achieved a clinical pregnancy after frozen embryo transfer. CONCLUSION(S): Although rare, hypersensitivity reactions may occur in patients receiving P-in-oil supplementation after IVF embryo transfer. Testing for tolerance and subsequent use of alternative P vehicles may be an effective strategy in managing patients with sensitivity to P-in-oil.

RESUMEN

Polycystic ovary syndrome (PCOS) affects between 4%-18% of reproductive-aged women and is associated with increased risk of obesity and obesity-related disease. PCOS is associated with hyperinsulinemia, which is known to impair fat oxidation. Research shows that carbohydrates from dairy and starch-based foods cause greater postprandial insulin secretion than carbohydrates from nonstarchy vegetables and fruits. The purpose of this study was to determine whether an ad libitum 8-week low-starch/low-dairy diet would improve fasting and postprandial fat oxidation after a high saturated fat liquid meal (HSFLM) in overweight and obese women with PCOS. Prospective 8-week dietary intervention using a low-starch/low-dairy diet in 10 women (body mass index ≥25 kg/m(2) and ≤45 kg/m(2)) with PCOS. Indirect calorimetry was used at fasting and for 5 h following consumption of the HSFLM to determine respiratory exchange ratio (RER), macronutrient oxidation, and energy expenditure (EE) at week 0 and week 8. Participants had a reduction in body weight (-8.1 ± 1.8 kg, p < 0.05) and fasting insulin (-19.5 ± 8.9 µg/mL, p < 0.05) after dietary intervention; however, these were not significantly correlated with improved fat oxidation. There was a reduction in fasting RER, and fasting and postprandial carbohydrate oxidation, and an increase in fasting and postprandial fat oxidation after adjusting for body weight. There was also significant difference in incremental area under the curve from pre- to post-diet for fat (0.06 ± 0.00 g/kg per 5 h; p < 0.001) and carbohydrate oxidation (-0.29 ± 0.06 g/kg per 5 h; p < 0.001), but not for RER or EE. In conclusion, an 8-week low-starch/low-dairy diet increased fat oxidation in overweight and obese women with PCOS.

RESUMEN

OBJECTIVE: To study diagnostic thresholds for polycystic ovary (PCO). DESIGN: Retrospective cohort study. SETTING: Academic hospital. PATIENT(S): Normoandrogenic ovulatory women and patients with polycystic ovary syndrome (PCOS). INTERVENTION(S): Two-dimensional (2D) and three-dimensional (3D) transvaginal ultrasound. MAIN OUTCOME MEASURE(S): The mean follicle number per ovary (FNPO) of both ovaries and the maximum number follicles in a single sonographic plane (FSSP) of either ovary were determined using 3D transvaginal ultrasound. Ovarian volume was determined using 2D transvaginal ultrasound. RESULT(S): Twenty-nine normoandrogenic ovulatory women were compared with 10 patients with PCOS. Diagnostic thresholds for PCO with 100% specificity as determined by receiver operator characteristic (ROC) curves were > or =20 for mean FNPO, > or =10 for maximum FSSP, and > or =13 cm3 for ovarian volume. Both 2D and 3D transvaginal ultrasound were highly accurate in the diagnosis of PCO as determined by areas under the curve (AUC) that were >90% for all three measures. CONCLUSION(S): Mean FNPO and maximum FSSP by 3D transvaginal ultrasound have comparable high accuracy for diagnosis of PCO. The diagnostic threshold with 100% specificity for mean FNPO is > or =20, which is greater than suggested by the Rotterdam Consensus Workshop in 2003. Use of the consensus standard, consequently, may result in overdiagnosis of PCO. A threshold of > or =20 mean FNPO using 3D transvaginal ultrasound may be appropriate to minimize false-positive diagnoses of PCO.

RESUMEN

Multiple gestations remain one of the leading causes of morbidity related to infertility therapy. In the realm of assisted reproductive technologies, multiple gestations can be significantly limited by the reduction in the number of embryos transferred. Significant concern remains that a reduction in the number of embryos transferred may appreciably lower overall chances for pregnancy. Promising new developments are unfolding that may permit improved detection of a single human embryo with high implantation potential. One such development is the use of sequential culture media to allow prolonged culture of embryos to the blastocyst stage. We report a case in which sequential culture and elective transfer of one blastocyst was successfully used in a patient with a profoundly poor obstetrical history because of the complications of high-order multiple gestations.
