Active clinical trials for "Polycystic Ovary Syndrome"

This study was performed to investigate the effects of metformin on controlled ovarian stimulation (COS), in vitro fertilization (IVF) outcomes, pregnancy outcomes, and comparison of serum and follicular fluid cytokines and hormones in patients with polycystic ovary syndrome (PCOS) undergoing IVF using gonadotropin-releasing hormone(GnRH) antagonist protocol.

The main purpose of this study is to test the effectiveness of nimodipine in preventing a luteinizing hormone (LH) surge in women undergoing ovulation induction with clomiphene citrate. It is important to prevent the premature LH surge in controlled ovarian stimulation to allow adequate recruitment of follicles, proper maturation of a dominant follicle before ovulation, and effectively time insemination with semen to allow fertilization of a mature egg to occur. The investigators are also conducting this study to determine medication side effect profile (including lightheadedness or dizziness from low blood pressure or rapid heart rate, headache, and nausea), patient treatment compliance, and clinical pregnancy (positive pregnancy test and ultrasound evidence of fetal heart rate). Finally, LH and follicle stimulating hormone (FSH) serum levels will be measured to determine effect of nimodipine on these hormones. As a calcium channel blocker, nimodipine has been shown to block calcium mediated release of gonadotropin releasing hormone in animal and preliminary human studies. The investigators hypothesize that nimodipine, a calcium channel blocker, will prevent or delay the LH surge during controlled ovarian stimulation cycles using clomiphene citrate in subfertile patients undergoing assisted reproduction with intrauterine insemination (IUI).

The investigators examined whether a combined therapy with low-dose spironolactone plus metformin is more effective than metformin alone in 52 overweight/obese Polycystic Ovary Syndrome (PCOS) patients.

Previous studies have demonstrated that Myo-inositol is capable of restoring spontaneous ovarian activity, and consequently fertility, in most patients with PCOS. The aim of our study is to investigate the role of folic acid conteined in the inositol preparation. The study group included 50 patients, randomly allocated to subgroup A (myo-inositol 1500 gr) and subgroup B (myo-inositol 2000 gr + folic acid 200 mcg). The investigation include menstrual pattern and hirsutism score evaluation, hormonal assays, oral glucose tolerance test, euglycemic hyperinsulinaemic clamp and lipide profile at baseline and after six months of treatment.

The purpose of this study is to determine whether oral cinnamon extract are effective in reducing insulin resistance parameters in women with polycystic ovary syndrome.

In 1935 the polycystic ovary syndrome was a clinical diagnosis made on the morphological appearance of the ovaries in association with amenorrhoea, hirsutism and frequently obesity. At that time wedge resection of the ovaries was introduced on an empirical basis and proved a successful treatment for the associated anovulation and infertility. In the ensuing fifty years the limitations of a purely surgical approach to therapy have become recognized and the importance of the biochemical abnormalities appreciated. Prevalence of polycystic Ovary Syndrome: The prevalence of polycystic ovary syndrome in any specified population is dependent upon the diagnostic criteria used, but does have some regional and ethnic variation. While most reports on the prevalence of polycystic ovary syndrome range between 2 and 20%, the chosen diagnostic criteria are recognized to influence the determined prevalence. Anti-mullerian hormone which is a predictor of ovarian reserve is known to decrease after laparoscopic ovarian drilling. On the best of our knowledge no study had been done to use the level of anti-mullerian hormone as a factor for planning the number of ovarian drills in each ovary.

The study is conducted at Arash Women's Hospital on all women undergoing the frozen embryo transfer cycle. Patients who signed informed consent will be randomly divided into two groups. The first group will receive GnRH agonist plus hormone replacement therapy for endometrial preparation. Group 2 will receive hormone replacement therapy. The random allocation and final outcome of the study will be assessed by a person who is unaware of the study process. Also, the statistician will be unaware of the study process

the study compare the hormonal-metabolic and reproductive outcome between combined metformin-letrozole and ovarian drilling in clomiphene resistant women with polycystic syndrome

Pneumoperitoneum is done by insertion of the verress needle at the inferior edge of the umbilicus putting into consideration the following tests: Needle test: Verress needle patency check. Hissing phenomenon: Needle introduced by open valve mechanism. Aspiration test: Placing a drop of water on the opening of the needle and examine its disappearance into the abdomen. Volume test: Changes occurred in the intra abdominal pressure during gas insufflations. Intra abdominal pressure 12-16 mmHg usually suitable for this pelvic surgery. Introduction of the laparoscopic instruments all in its place Laparoscopic telescope : From the inferior edge of umbilicus through trocar and sleeve which inserted by corkscrew technique then removed to allow the telescope insertion which connected to light source , camera head and color monitor. 2nd and 3rd punctures were done allowing another two graspers to be inserted usually at a point represent outer 1/3 of the lateral abdominal wall in an imaginary line from umbilicus to iliac bone Puncturing technique : Fixation of one ovary away from intestine by grasping the ovarian ligament with the traumatic grasper which allow good exposure of the ovary and allow drilling . Drilling needle was introduced and connected by monopolar current, held against ovarian surface for 4 seconds using a power of 40 watt, 4 puncture was done in each ovary with putting into consideration that the puncture must be not superficial and it must go deep through the main substance of the ovary. Cooling of the ovary by lactated ringer's solution, finally removal of all instruments under vision after exclusion of any complication .

Polycystic ovary syndrome affects a striking 9-18% of Australian reproductive aged women and has been associated with a number of metabolic abnormalities. Given the strong correlation between metabolic abnormalities and increased sympathetic activity, we hypothesise that reducing this activity using medication (moxonidine) can help improve the metabolic abnormalities, and therefore improve outcomes in polycystic ovary syndrome.
