Abstract
Bleomycin sclerotherapy is used in the treatment of cystic lesions; however, the histopathological changes are undefined. Present animal models of cystic diseases are not adequate for the study of sclerotherapy of hepatic cysts, primarily because the established cysts in these models are too small in size. The aim of the present study was to establish a new animal model of simple hepatic cysts, and assess the histopathological changes after bleomycin sclerotherapy. Rabbit gallbladder, with ligaturing of the cholecystic duct whilst preserving cholecystic vessels, was used as a model for simple hepatic cysts. Bleomycin (2 mg dissolved in 1 ml saline) was injected into the aspirated gallbladder, gallbladder tissue was harvested (after 1, 7, 14, 28, 42, 56 and 84 days) and histopathological changes were evaluated (n=4 per group). Additionally, control rabbit gallbladders were injected with 1 ml saline and sampled after 14 days (n=4). Histopathological changes were evaluated using hematoxylin-eosin and Masson's trichrome staining, and immunohistochemistry for CD20-, CD43- and CD68-positive cells was performed. The integrated optical density (IOD) of immunohistochemical staining and average positive stained area percentage (APSAP) of collagen were quantitatively analyzed. The results revealed gallbladders in the control group had regular epithelial cells with no visible inflammation or fibrosis. In the experimental group, epithelial cells were swollen and necrotic on the first day, and were replaced gradually by single-layer flat cells from day 56. Inflammatory infiltration was found in the submucosa, and the IOD of T cells, B cells and macrophages were highest on day 1, and these parameters declined gradually, eventually disappearing. The APSAP of collagen was highest on day 7, and gradually declined thereafter. The results suggest that histopathological changes after bleomycin sclerotherapy of a simple hepatic cyst model were characterized by sequential epithelial destruction, inflammatory cell infiltration, collagen proliferation and epithelial partial regeneration.

Abstract
Background/aim Ovarian hyperstimulation syndrome (OHSS) is a complication of ovarian stimulation with increased vascular endothelial growth factor (VEGF) and vascular permeability in the ovarian tissue. Transient receptor potential melastatin 2 (TRPM2) is known to be associated with angiogenesis and vascular permeability. In this experimental study, we aimed to investigate the activity of TRPM2 in the development of OHSS. Materials and methods Fourteen immature female rats were divided into two groups. Group 1 was the control group, and Group 2 was the OHSS group that was exposed to 10 IU of subcutaneous application of FSH for four days and 30 IU of human chorionic gonadotropin (hCG) on the 5th day. At the end of the experiment, the ovaries were removed. The right ovarian tissues were stored in 10% formol for histopathological and immunohistochemical examination. The left ovarian tissues were stored at –80 °C for biochemical examinations. VEGF, tumor necrosis factor-alpha (TNF‐α) and malondialdehyde (MDA) levels were measured in the ovarian tissue. Congestion, edema, apoptosis and TRPM2 immunoreactivity were evaluated. Results There was a significant increase in ovarian weight in the OHSS group compared to the control group. There was a significant increase in congestion, edema, apoptosis and TRPM2 immunoreactivity in the OHSS group. A significant increase in tissue levels of VEGF, TNF‐α and MDA was also found in the OHSS group compared to the control group. Conclusion As a result of our experiment, it was found that increased TRPM2 immunoreactivity on hyperstimulated rat ovary may be the reason or result of edema and congestion. Further studies are needed to discuss our results.

Abstract
Exposure to an electromagnetic field (EMF) can have adverse effects on many organs and tissues, including the reproductive system. This study aimed to investigate the effects of EMF exposure during prenatal and postnatal periods on ovarian development in rat offspring. In this study, rat pups born from eight pregnant rats were used. EMF exposure was initiated on the first day of pregnancy and continued until the 42nd postnatal day. The blood and ovarian tissue samples of female offspring in sham and EMF groups were collected when they reached the age of 42 days. Follicle-stimulating hormone levels were significantly higher in the EMF group than in the sham group. Estradiol levels were significantly lower in the EMF group than in the sham group. Tissue-inducible nitric oxide synthase (iNOS) levels and expression were significantly greater in the EMF group than in the sham group. In the EMF group, congestion, bleeding areas, and degeneration of follicle structures were observed in ovarian tissue. The findings suggest that exposure to 50-Hz, 3-mT EMF used in this study during prenatal and postnatal periods may lead to impaired ovarian structure and function in female offspring. EMF may affect ovarian physiology by increasing iNOS levels and may lead to fertility disorders.

Abstract
Background/aim The purpose of this study was toinvestigate the effects of 10% povidone–iodine (PI) sclerotherapyon ovarian cyst diameter through an experimental study. Materials and methods To be able to create ovarian cysts, right unilateral salpingectomy was performed on 20 Wistar albino rats. One month after the operation, the abdomens of all rats were reopened. Sixteen rats with macroscopic ovarian cysts were divided randomly into 2 groups consisting of 8 rats. Group 1 (G1): the cyst content was only aspirated. Group 2 (G2): the ovarian cyst was aspirated and then the cystic cavity was irrigated with PI. Abdomens of all rats were closed and 1 month later they were reopened. Tissues of the right ovaries of the rats were embedded in paraffin blocks for histopathological examination. Follicle count, fibrosis, and congestion were evaluated under a light microscope. Results For G1, there was no difference in cyst diameters before and after aspiration. In G2, a decrease was observed in cyst diameter. There was no difference in ovarian reserve between the 2 groups. When compared with G1, an increase in fibrosis and congestion was determined in G2. Conclusion Sclerotherapyinto the ovarian cyst for a 5-min period using 10% PI reduces cyst diameter without any change in ovarian reserve.

Abstract
The aim of this study was to compare the effects of only aspiration with aspiration and 5% trichloroacetic acid (TCA) application on ovarian cyst size and ovarian reserve. The ovarian cysts of 14 rats that were divided into two groups randomly were investigated after total salpingectomy procedure. G1 was the group of saline application after cyst aspiration, while in G2, after aspiration 5% TCA at half amount of aspiration volume was injected into the cyst and re-aspirated after five minutes. The abdomens of the rats were closed and re-explored after 1 month. The cyst diameters of the rats in each group were measured. Ovaries were removed for histopathological examination. There was no significant difference in cyst diameter in G1 before and after aspiration. In G2, there was a significant decrease in cyst size after TCA application. Ovarian follicle counts were not significantly different between the two groups. In conclusion, application of 5% TCA to the ovarian cysts for five minutes significantly reduces the cyst size. Impact Statement What is already known on this subject: Minimally invasive therapies come into prominence to avoid surgical complications and diminished fertility in the treatment of ovarian cysts. USG-guided aspiration and sclerosis has been reported as cost-efficient and effective treatment methods for localised benign cysts in other organs such as the thyroid, parathyroid, liver, kidney and spleen. It has been shown that sclerotherapy applied to infertile women with ovarian cysts reduces pelvic pain without affecting the number of follicles, term pregnancy and abortion rates, extracted oocytes, embryo quality or hormonal levels when compared to non-ovarian cystic infertile women. TCA is a chemical agent that is topically applied, not systemically absorptive, which causes denaturation of proteins and structural cell death, resulting in coagulation necrosis after chemical cauterisation. For this reason, we used 5% TCA to treat simple ovarian cysts on a rat model. What the results of this study add: In this experimental study, we showed that the application of 5% TCA into the cyst for five minutes - then aspirated - significantly reduced the size of the ovarian cysts. Five percent TCA application did not affect the ovarian reserve. What the implications are of these findings for clinical practice and/or further research: Our study is original because of the fact that to the best of our knowledge, this is the first study about the use of 5% TCA in treatment of ovarian cysts in the literature.

Abstract
INTRODUCTION Treatment of ovarian endometriomas is commonly achieved through laparoscopic surgery and this can be effective in eliminating the disease, although a majority of recent trials documented an adverse effect of surgery on ovarian reserve markers. With the advancement in imaging techniques, ovarian endometriomas are increasingly diagnosed at an earlier stage when the endometrioma may be smaller, less fibrotic and more responsive to medical treatment, making an evaluation of medical options critically important. AREAS COVERED The review focuses on currently utilized pharmacologic therapies for endometrioma (oral contraceptives, the levonorgestrel-releasing IUS, the hormone-releasing subdermal implant, Implanon); experimental and future treatments are also mentioned (GnRH antagonists, progesterone receptor modulators, antioestrogens, newer subdermal implants and intracystic administration of pharmacologic agents). Finally, the usefulness of post-operative adjuvant medical treatments is discussed Expert opinion: Today, reliable, non-invasive diagnostic procedures of an ovarian endometrioma are available and should be utilized to identify its presence and type of pathology. In a young patient, classic medical therapies such as oral contraceptives and synthetic progestins should be tried first to alleviate symptoms. Only when these regimens fail, should a minimally invasive surgery be envisaged. Following endoscopic surgery, adjuvant medical treatment may reduce recurrence of both symptoms and the lesion.

Abstract
The effects on human health of electromagnetic field (EMF) have begun to be seriously questioned with the entry into daily life of devices establishing EMF, such as cell phones, wireless fidelity, and masts. Recent studies have reported that exposure to EMF, particularly during pregnancy, affects the developing embryo/fetus. The aim of this study was therefore to examine the effects of exposure to continuous 900-Megahertz (MHz) EMF applied in the prenatal period on ovarian follicle development and oocyte differentiation. Six pregnant Sprague Dawley rats were divided equally into a non-exposed control group (CNGr) and a group (EMFGr) exposed to continuous 900-MHz EMF for 1 h daily, at the same time every day, on days 13-21 of pregnancy. New groups were established from pups obtained from both groups after birth. One group consisting of female pups from CNGr rats was adopted as newborn CNGr (New-CNGr, n = 6), and another group consisting of female pups from EMFGr rats was adopted as newborn EMFGr (New-EMFGr, n = 6). No procedure was performed on New-CNGr or New-EMFGr rats. All rat pups were sacrificed on the postnatal 34th day, and their ovarian tissues were removed. Follicle count, histological injury scoring and morphological assessment with apoptotic index criteria were performed with sections obtained following routine histological tissue preparation. Follicle count results revealed a statistically significant decrease in primordial and tertiary follicle numbers in New-EMFGr compared to New-CNGr (p < 0.05), while atretic follicle numbers and apoptotic index levels increased significantly (p < 0.05). Histopathological examination revealed severe follicle degeneration, vasocongestion, a low level of increased stromal fibrotic tissue and cytoplasmic vacuolization in granulosa cell in New-EMFGr. Prenatal exposure to continuous 900-MHz EMF for 1 h each day from days 13-21 led to a decrease in ovarian follicle reservoirs in female rat pups at the beginning of the prepubertal period.

Abstract
OBJECTIVES To examine the effect of 95% ethanol sclerotherapy (EST) administered over 5 minutes on cyst diameter and ovarian tissue in experimentally induced simple ovarian cysts in a rat model. MATERIALS AND METHODS In order to induce ovarian cysts, unilateral total salpingectomy was performed in regularly menstruating adult female Wistar albino rats (n=20) between 12 and 14 weeks of age and weighing between 200 and 220 g. One month after the procedure, the abdominal cavity was opened and 14 rats (70%) were found to have developed macroscopic cysts. Rats with macroscopic cysts (n=14) were assigned into two groups in a prospective and single-blinded manner: group 1 (G1) (n=7), control rats; and group 2 (G2) (n=7), 5-minute EST 95% group. Cyst diameter was measured and recorded for each rat. In G2, after whole cyst fluid was aspirated the cystic cavity was irrigated with 95% ethanol, approximately equal to half of the aspirated cyst volume, after which an interval of 5 minutes was allowed and same amount was re-aspirated and the abdominal cavity was closed. One month after this procedure, abdominal cavities were reopened and intra-abdominal adhesion scoring was performed in both groups. Cyst diameter was measured for each rat, and the right ovary was removed, fixed in 10% formaldehyde, and transported to the laboratory. A histologic assessment of the ovarian tissues was performed under light microscopy following staining with hematoxylin and eosin. Mann-Whitney U-test was used for statistical analysis. A P-level less than 0.05 was considered significant. RESULTS In comparison with G1, there was a statistically significant reduction in the mean ovarian cyst dimensions in G2, while there were no significant differences between the two groups with respect to total number of follicles. Again, a significant increase in apoptotic activity and germinal epithelial degeneration was observed in G2 as compared to G1. The two groups were similar in terms of adhesion formation. CONCLUSION Although 95% EST results in a reduction in the size of simple ovarian cysts, this effect seems to be achieved at the expense of ovarian tissue injury.

Abstract
OBJECTIVE We aimed to investigate the effects of unilateral total salpingectomy procedure on ovarian follicular reserve, apoptosis, and proliferating cell nuclear antigen (PCNA) staining in this study. STUDY DESIGN Fourteen female Wistar Albino rats of 12 weeks were randomly divided into two groups. Abdomen midline incision was conducted under general anesthesia. Group 1(G1) (n=7): Group in which only the abdomen was opened and closed, Group 2(G2) (n=7): Group that underwent right total salpingectomy. After 1 month, abdomens of all rats were opened. Ovaries were macroscopically evaluated. Right ovarian tissue was quickly removed, fixed in 10% formaldehyde, and paraffin blocks were prepared.' The existence of fibrosis was identified with the usage of light microscope. Follicles were microscopically classified and counted. The prevalence of cytoplasmic immune staining and TUNEL staining was scored semi-quantitatively. STATISTICAL ANALYSIS SPSS 17.0 software was used for the statistical analysis of data. First, Kruskal-Wallis variance analysis was conducted, and then Mann-Whitney U test was utilized for inter-group dual comparisons for parameters found as p<0.05. RESULTS While the number of CL was found out dramatically high, secondary follicle count was found out to be significantly low in G2. Also in G2, although the number of atretic follicle and fibrosis were found out significantly increased, and the score of the angiogenesis was found to be significantly decreased in CL. When compared PCNA immunoreactivity in granulosa cells with the control group, there was a significant decrease in G2. When compared the malondialdehyde (MDA) immunoreactivity with G1 a significant increase was established in G2. Apoptosis score of ovarian follicles in granulosa cells was significantly higher in G2. CONCLUSIONS In this experimental study, the decrease in the ovarian reserve and PCNA staning of granulosa cells, an increase in apoptosis, fibrosis and the number of atretic follicles in unilateral total salpingectomy operation were analyzed in rats. We found out significantly higher MDA staining rates in G2 in comparison to in G1. According to the study, the unilateral total salpingectomy procedure can damage to the same side ovarian tissue by means of the ischemia and reperfusion injury at the ovarian tissue.
