We studied both morphology and steroidogenic activity of porcine ovaries after dexamethasone (DMX)-induced polycystic status. In the polycystic-changed ovaries, an increase in the number of DbetaH-IR and/or NPY-IR nerve terminals was found in the wall of follicles, cysts and blood vessels. After DXM injections, we observed changes in the mean contents of progesterone, androstendione, estradiol-...
BACKGROUND Polycystic ovarian syndrome (PCOS) is a heterogeneous endocrine disorder affecting women of reproductive age. The syndrome is characterized by a combination of polycystic ovarian morphology, clinical features and biochemical indices. The objective of this prospective observational study was to investigate the relationship between the total ovarian volume and the ovarian stromal volum...
Primary ovarian insufficiency (POI) and polycystic ovarian syndrome are ovarian diseases causing infertility. Although there is no effective treatment for POI, therapies for polycystic ovarian syndrome include ovarian wedge resection or laser drilling to induce follicle growth. Underlying mechanisms for these disruptive procedures are unclear. Here, we explored the role of the conserved Hippo s...
Polycystic ovary syndrome is a multi-factorial disease. Its etiopathogenesis has not been elucidated in detail. It is the most common endocrine disorder in women of child-bearing age. This disease entity is primarily characterized by disrupted ovulation and hyperandrogenism, but the clinical picture can be diversified and symptom intensity can vary. Currently, the sonographic assessment of ovar...
Abstract Polycystic Ovarian Syndrome (PCOS) is a disease that characterized by an increased Gonadotropin-Releasing-Hormone (GnRH) pulsatile frequency, causing altered LH/FSH ratio. More precisely Luteinizing Hormone (LH) secretion compared to decreased Follicle-Stimulating (FSH) leads the development of hyperandrogenism and low-level concentration estrogens therefore negative estrogenic feedbac...
Infertility is defined as inability of a couple to conceive within a certain period of time one to two years of frequent unprotected intercourse [1]. It is seldom a physically debilitating disease, but couple’s psychosocial harmony is severely affected. The important causes of infertility in female are tubal and peritoneal factors (25-35%), ovulatory factors (30-40%), endometriosis (1-10%) [2]....
The use of ovarian stimulation for infertility treatment is associated with side effects of ovarian hyperstimulation syndrome (OHSS) and potential cancer risk. This is also true in high risk women such as those polycystic with ovary (PCO) and polycystic ovarian syndrome (PCOS). In vitro maturation (IVM) of oocytes was primarily developed to make IVF safe for women with PCO and at high risk of ...
Background: Polycystic ovary syndrome (PCOS) is one of the most common causes of anovulation, infertility and hyperandrogenism in women, affecting 5-10% of women of reproductive age. Due to the ethical limitations on human experimentation, appropriate animal models that mimic many or all PCOS characteristics would facilitate research leading to improved understanding of the pathogenesis of PCOS...
