Are there any association between polycistic ovary syndrome and congenital abnormalities of Müllerian ducts

Background/Aim. There are many specificities of merital infertility and sometimes surprising connections between some thinks with no connections at first sight. Examinations of these patients imply diagnostic actions such as the blood basal hormone sample, doing hysterosalpingography, ultrahysterosonography, ultrasound examinations, and sometimes laparoscopy and hysteroscopy if there are necessary. The aim of the study was to determine the characteristics of the connection between policystic ovary (PCO) syndrome (Sy) and congenital M?llerian ducts abnormalities. Methods. This study included 356 patients treated in the period from January 1, to December 31, 2009, in the Department of Infertility of the Clinic for Obstetrics and Gynecology in Nis, Serbia. Exclusion criteria were no myoma, ovary cysts, tubal and male factors of infertility. Results. A total of 180 patients were divided into 3 groups: the group I with PCO sy, the group II with uterine congenital malformation and the group III with a combination of these disorders. The middle age of patients was 29.6 ? 4.8, body mass index (BMI) was 26.1 ? 4,8 kg/m2 the middle thicknes of endometrium was 5.2 + 2.7 mm, and there were no significant differences between the examined groups. There were no significant among in a number of miscarriages in the examined groups. We found that PCO Sy and congenital abnormalities of M?llerian ducts were conjoint in 30% of examined patients. Conclusion. Conjoined PCO Sy and congenital abnormalities of M?llerian ducts do not result in a higher number of misscarriages than only either PCO Sy or abnormalities of M?llerian ducts. It is important to check BMI, basal level of follicle stimulating hormone and number of antral follicles because the induction protocol and concentracion of inductors depends on these characteristics, thus, the successful cycles and pregnancy.

Permselectivity of blood follicle barriers in mouse ovaries of the mifepristone-induced polycystic ovary model revealed by in vivo cryotechnique

Despite the potential association of polycystic ovary (PCO) syndrome with hemodynamic changes, follicular microenvironment and the involvement of blood follicle barriers (BFB), a histopathological examination has been hampered by artifacts caused by conventional preparation methods. In this study, mouse ovaries of a mifepristone-induced PCO model were morphologically and immunohistochemically examined byin vivocryotechnique (IVCT), which prevents those technical artifacts. Ovarian specimens of PCO model mice were prepared by IVCT or the conventional perfusion fixation after s.c. injection of mifepristone. Their histology and immunolocalization of plasma proteins, including albumin (molecular mass, 69 kDa), immunoglobulin G (IgG, 150 kDa), inter-α-trypsin inhibitor (ITI, 220 kDa), fibrinogen (340 kDa), and IgM (900 kDa), were examined. In the PCO model, enlarged blood vessels with abundant blood flow were observed in addition to cystic follicles with degenerative membrana granulosa. The immunolocalization of albumin and IgM in the PCO model were similar to those in normal mice. Albumin immunolocalized in the blood vessels, interstitium or follicles, and IgM was mostly restricted within the blood vessels. In contrast, immunolocalization of IgG, ITI, and fibrinogen changed in the PCO model. Both IgG and ITI were clearly blocked by follicular basement membranes, and hardly observed in the membrana granulosa, though fibrinogen was mostly observed within blood vessels. These findings suggest that increased blood flow and enhanced selectivity of molecular permeation through the BFB are prominent features in the PCO ovaries, and changes in hemodynamic conditions and permselectivity of BFB are involved in the pathogenesis and pathophysiology of PCO syndrome.

Menstrual cycle disorders in polycystic ovary syndrome: Ultrasonographic characteristics and hormonal status

Introduction The polycystic ovary syndrome is primarily characterized by an association of hyperandrogenism and anovulation. The aim was to determine the incidence of menstrual cycle disorders in patients with PCO syndrome and the relation with ultrasonographic and hormonal findings. Material and methods A retrospective study examined the ultrasonographic findings and hormonal status in patients with polycystic ovary syndrome at the Department of Obstetrics and Gynecology of the General Hospital in Subotica. The sample comprised 39 patients. Results and conclusions Most frequently age at menarche was 14 years (29%) in obese and 10 years (45.5%) in normal weight patients. There was not a significant difference in duration of menstrual bleeding in both groups of examined patients, whereas amenorrhoea was significantly more frequent in obese patients (29.4%) than in patients with normal weight (4.7%). On the basis of presented results (increased percentage of severe disorders of menstrual cycle in all patients in subgroup C and increased percentage of menstrual disorders in patients with high stromal density in relation to those with normal echogenity of stroma) it can be concluded that there is a correlation between ultrasonographic findings of ovaries (number of microcysts, volume and density of the stroma) and menstrual cycle disorders, the polycystic ovary syndrome.
