In the mouse ovary, the primordial follicle pool is established through a diverse array of signaling pathways and tissue remodeling events. Growth arrest specific gene two (GAS2) is a highly conserved cytoskeleton-associated protein whose in vivo function remains unclear. In Drosophila, loss of the GAS2 homolog, Pigs, results in infertility. We demonstrate herein that, in the mouse ovary, GAS2 is expressed in the stromal cells surrounding the oocyte cysts on 16.5 dpc, and in stromal cells surrounding growing follicles during juvenile and adult life...

Multiple aspects of organismal physiology influence the number and activity of stem cells and their progeny, including nutritional status. Previous studies demonstrated that Drosophila germline stem cells (GSCs), follicle stem cells (FSCs), and their progeny sense and respond to diet via complex mechanisms involving many systemic and local signals. AMP-activated protein kinase, or AMPK, is a highly conserved regulator of energy homeostasis known to be activated under low cellular energy conditions; however, its role in the ovarian response to diet has not been investigated...

INTRODUCTION: Testicular cancer is one of the most frequent in young men and its incidence is increasing in recent years because of incidental finding during routine ultrasound exams. Adenomatous hyperplasia of the rete testis is one of the benign and rare pathological types incidentally detected and very few cases are described in the literature. CASE REPORT: A 40 years old man come to our attention for a balanoposthitis without testicular pain. During andrological examination we performed palpation of the testes and we noticed a palpable nodule of hard consistency in the left testicle...

BACKGROUND: Observational data and results from post-hoc analyses in clinical trials suggest that direct oral factor Xa inhibitors might increase menstrual bleeding intensity in women of reproductive age, but the extent of this effect is unknown. We aimed to investigate the management and outcomes of vaginal bleeding complications during therapy with direct oral factor Xa inhibitors in a case series of women of reproductive age. METHODS: To identify individuals for inclusion in this case series, we searched two sources of prospectively collected data from women of reproductive age treated with direct oral factor Xa inhibitors: the non-interventional Dresden NOAC Registry (NCT01588119), which is based in the administrative district of Dresden (Saxony, Germany), and all locally archived data from phase 3 trials of direct oral factor Xa inhibitors done at University Hospital Carl Gustav Carus Dresden...

Most common ovarian diseases appear to be cystic or ovarian tumours. These conditions may affect health, fertility or even the life of the animal. Literature related to ovarian cysts and neoplasia in dogs was assessed to summarize studies and case series on ovarian cysts and primary ovarian tumours in regard to epidemiologic, clinical and fertility aspects. Two research papers on histopathological examination of ovarian cysts could be identified. Seven research papers on ovarian tumours were also assessed, showing inconsistent results on the frequency of occurrence of different types of neoplasia...

Hyperreactio luteinalis (HL) is a rare condition that is characterized by bilateral ovarian enlargement and multiple thin walled cysts. Hypersensitivity of the ovary to circulating human chorionic gonadotropin (hCG) is playing the main role in pathophysiology. HL observed in cases where there is high serum ß-HCG levels, similarly to gestational trophoblastic disease, multiple pregnancies, hydrops fetalis and after fertiliy treatment. Most of HL are self limiting condition and patients are asymptomatic. Differentiation from ovarian malignancies is important...

As a flatfish, the turbot (Scophthalmus maximus) is one of the most important farmed fish species with great commercial value, which has a strong sexual dimorphism on growth rate and sexual maturity. In this study, using histology, the basic information on proliferation and migration of germ cells and early gonadal development during sex differentiation in turbot were described in detail. There were six to nine individual primordial germ cells (PGCs) with large nuclei until 15 days post-hatching (dph). The PGCs located under the mesonephric ducts undergo migration along the dorsal mesentery toward the region of the genital ridge from 0 to 15 dph...

Endometriosis generally occurs in the ovary. Intestinal endometriosis is rare. About 1 % of all endometriosis cases become malignant. Malignant transformation of small intestinal endometriosis is very rare. A 55-year-old woman who underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy and omentectomy for endometriosis 7 years ago presented to her primary care doctor with melena. A tumor was detected in the right lower abdomen by ultrasonography. The doctor referred her to our hospital...

INTRODUCTION: Ovarian neuroendocrine tumors are extremely rare. In the ovary, the term of neuroendocrine tumor is usually related to carcinoid tumors although it may be sometimes applied to neuroendocrine carcinomas of non-small cells or small cells cancers usually occurring in the lungs. These carcinoid tumors may develop de novo or from other tumors including teratomas. CASE REPORT: We report a patient who presented with an ovarian carcinoid tumor developed, near or from a dermoid cyst, which was original by its mode of discovery in the dermatology department...

The term collision tumor refers to the coexistence of two adjacent but histological distinct tumors with no histological admixture at the interface. Collision tumors involving ovaries are extremely rare. A collision tumor composed of a dermoid cyst and fibrothecoma is extremely rare in menopausal women. The mechanism of the development of collision tumor is uncertain. During clinical evaluation, differentiation of characters of these ovarian tumors is important to decide appropriate treatment strategies and for good prognosis...

This report describes an innovative unilateral ovariectomy technique for the surgical treatment of follicular cysts in dairy cows. Five cows, with a diagnosis of follicular cysts, were submitted to unilateral ovariectomy via a paralumbar fossa approach, in standing position. The linear cutter proved useful for clamping the ovary, stapling the vessels and cutting in one stroke, thus reducing surgery times. After unilateral ovariectomy, all cows underwent heat 7-30 days after surgery, and three cows became pregnant...

Letrozole (LTZ), one of the ovulation induction medications, is increasingly prescribed in various gynaecological conditions. Previous studies have demonstrated its potential hazardous effect on the ovarian surface epithelium (OSE) as well as on tubal epithelial cells (TEC). However, it is not clear whether this effect could be reversed by LTZ cessation. Therefore, the objective of our study was to investigate the effect of stoppage of LTZ on these cells after 12 cycles of ovarian stimulation. A total of 54 Sprague Dawley rats were used in this study, divided equally into control, LTZ12 and CES12 groups (received saline, 12 cycles of LTZ and 12 cycles of cessation post-LTZ12 respectively)...

Our knowledge of testicular germ cell neoplasms has progressed in the last few decades due to the description of germ cell neoplasia in situ (GCNIS) and a variety of specific forms of intratubular germ cell neoplasia, the discovery of isochromosome 12p and its importance in the development of invasiveness in germ cell tumors (GCTs), the identification of specific transcription factors for GCTs, and the recognition that a teratomatous component in mixed GCT represents terminal differentiation. Isochromosome 12p and 12p overrepresentation, collectively referred to as 12p amplification, are fundamental abnormalities that account for many types of malignant GCTs of the testis...

The effects of neonatal testosterone or dihydrotestosterone exposure on ovarian follicular dynamics were analysed at prepubertal, pubertal or adult age in Wistar rats. Both androgens induced a transitory increase on follicular endowment that was partially corrected at puberty. At adult age testosterone prevented ovulation, without significant modifications on follicular dynamics. An increased number of cystic structures were observed from puberty to adult age. However, ovaries of rats treated with dihydrotestosterone showed follicles with evident morphological alterations in granulosa and thecal layers although several corpora lutea were observed...

BACKGROUND: Torsion is known to be the most frequent complication of ovarian teratomas. Torsion of the adnexa usually manifests with severe abdominal pain and is treated as an acute surgical emergency. However, it may be asymptomatic. Autoamputation of an ovary, along with other adnexal structures, due to previous torsion is extremely rare. CASE PRESENTATION: A parasitic ovarian teratoma that underwent torsion, autoamputation, and reimplantation was found incidentally during laparoendoscopic single-site surgery (LESS)...

Ovariohysterectomy (OHE) of bitches is a matter of conflict depending on the region and country in the world. In a descriptive, prospective cross-sectional study uterine tracts and ovaries exhibiting gross pathologic findings (n = 76) were collected post-surgery from a reference population of 3600 bitches (2,11% incidence) undergoing elective ovariohysterectomy during the warm-humid season (September-to-November 2013, average 26ºC) and were evaluated by histopathology examination. Data were evaluated by descriptive statistics and Chi-Squared test...

Endometriosis occurs in 5%-10% of fertile women, usually in the pelvic region, such as the ovaries, uterine ligaments, pelvic peritoneum, and rectovaginal septum. A mesenteric endometriotic cyst is an exceptional observation and difficult to diagnose preoperatively. We report a case of a large mesenteric endometriotic cyst treated by laparoscopy. A 21-year-old Caucasian woman was admitted as an emergency to our Academic Hospital on the 30th day postpartum for abdominal pain and a palpable epigastric mass. A CT scan revealed a mass measuring 7...

Lipoleiomyoma of the uterus is a rare variant of leiomyoma, and lipoleiomyoma of the broad ligament is still rarer, with only a handful of cases being reported. The present case was a perimenopausal woman who presented with a huge lower abdominal mass. Ultrasonography and computed tomography showed a heterogeneous solid mass in the left adnexa. The histopathological findings confirmed the nature of the lesions as a benign lipoleiomyoma with dermoid cyst of the left ovary and its other associated benign lesions, were the interesting features seen in this case which were not suspected clinically and radiologically...

PURPOSE: To review the radiological appearances of corpus luteum cysts and their imaging mimics. CONCLUSION: Corpus luteum cysts are normal post-ovulatory structures seen in the ovaries through the second half of the menstrual cycle and the first trimester of pregnancy. The typical appearance, across all modalities, is of a 1- to 3-cm cyst with a thick crenulated vascularized wall. Occasionally, similar imaging findings may be seen with endometrioma, ectopic pregnancy, tuboovarian abscess, red degeneration of a fibroid, and ovarian neoplasia...
