Sonographic incidence of polycystic ovaries in a gynecological population

The prevalence of polycystic ovaries in a large population of 1078 women of reproductive age was determined by pelvic ultrasonography. The ovarian ultrasonic appearance of 183 (17%) women met the morphological criteria of polycystic ovaries. Of these women, 147 (80.3%) had irregular cycles (group A) and 36 (19.70%) had normal cycles (group B). The remaining women constituted the control group. Ovarian volume was calculated in all women in whom at least one ovary was visualized. Serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH) and testosterone were measured in 124 women from group A, 25 from group B and 50 controls. Mean ovarian volume was statistically higher in both group A (13.4 ml) and group B (11.8 ml) than in the control group (6.2 ml). Mean LH/FSH ratio and mean testosterone values were statistically higher in group A only (2.1 and 1.1 ng/ml, respectively) compared with the mean values in the control group (0.7 and 0.7 ng/ml, respectively). Obesity and hirsutism were more common in group A than in group B and the controls. Screening the ovaries in women of reproductive age and subsequent assessment of morphology in polycystic ovaries can aid in the diagnosis of this condition in patients who may have a varied clinical presentation.

Serum markers of immune activation in women undergoing in-vitro fertilization and embryo transfer

We evaluated serum concentrations of two early and sensitive markers of immune activation, interleukin-2 receptor (sIL-2R) and intercellular adhesion molecule-1 (ICAM-1) in two age-matched groups of in-vitro fertilization (IVF)-embryo transfer women, group I (n = 26) without and group II (n = 40) with methylprednisolone (MPD) supplementation of the luteal phase, on the days of oocyte retrieval (sample A) and embryo transfer (B), and second (C) and 13th (D) days post-transfer and in 20 normally cycling women (controls) on the day of luteinizing hormone (LH) peak. No difference in the outcome of the IVF-embryo transfer was observed between groups I and II. In sample A, both immunomarker concentrations showed no significant difference between the two groups of IVF women, while they were significantly higher (P < 0.01) than values in controls. In cycles in which conception occurred, significantly higher immunomarker concentrations were observed in sample A of both groups I and II compared with those in unsuccessful cycles of the same group. A significant decrease of both sTL-2R and ICAM-1 was noticed in sample B only in group II (P < 0.0001 and P < 0.001 respectively; paired t-test) that continued further in the late luteal phase only in the case of conception, independently of MPD supplementation. These data suggest that (i) due to multiple ovulations, IVF-embryo transfer women show elevated concentrations of sIL-2R and ICAM-1 at oocyte retrieval; (ii) since, even at oocyte retrieval stage, high concentrations of immunomarkers are associated with IVF-embryo transfer success, sIL-2R and ICAM-1 could be used as early indicators for conception cycles; (iii) transient suppression of T cell activity by MPD supplementation following IVF-embryo transfer does not improve pregnancy rate

Discordant secretion of pregnancy specific β1-glycoprotein and human chorionic gonadotropin by human pre-embryos cultured in vitro

Objective: To study and compare the secretion of pregnancy specific β1- glycoprotein (SP1) and human chorionic gonadotropin (hCG) by human pre- embryos, cultured in vitro, with their respective morphological development. Design: Spare human pre-embryos from randomly selected women participating in a program of in vitro fertilization (IVF) were studied prospectively. Setting: Pre-embryos were cultured, and hormone release was determined in academic research laboratories. Patients, Participants: Pre-embryos (n = 108) cultured for 14 days after fertilization in Ham's F-10 medium (GIBCO Ltd., Paisley, Scotland) were observed, and hCG and SP1 were measured in the culture media at regular intervals. Main Outcome Measures: Discordant secretion of SP1 and hCG. Results: Of the 98 bipronucleate pre-embryos, 53.6% formed blastocysts, 17.3% of which hatched. Human chorionic gonadotropin was detected from day 7 after fertilization concomitantly with blastocyst formation, thereafter showing a logarithmic increase (maximum 10,650 mIU) until the first signs of embryonic disintegration. Pregnancy- specific β1-glycoprotein release started 3 to 4 days after fertilization independently of the morphological development and the future production of hCG, thereafter displaying a nonlogarithmic increase (maximum 41 ng). Conclusions: Hormone secretion and morphological development are unique for each pre-embryo. Human chorionic gonadotropin and SP1 seem to have different biochemical and physiological regulation

Hematological parameters of the mother and neonatal status during normal labor

This study reviews the relationship between hematological parameters of the mother and the newborns status. Our material consisted of 180 pregnant women with singleton pregnancies who had an uncomplicated vaginal delivery. A negative relationship was noted between the pH and the maternal hemoglobin values both in the umbilical artery and vein (r = -0.27, p < 0.001, for the umbilical vein and r = -0.32, p < 0.0001, for the umbilical artery). A negative relationship was also noted between the umbilical vein pH and the maternal hematocrit, which was statistically significant (r = -0.28, p = 0.001). A similar negative correlation was observed between the umbilical artery pH and the maternal hematocrit (r = -0.32, p < 0.0001). In conclusion, maternal hematological parameters (hemoglobin, hematocrit) can affect the fetal acid base balance. © 1997 S. Karger AG, Basel
