Filter by:Recent studies have shown that C natriuretic peptide is produced from granulosa cells, increasing cumulative guanosine monophosphate (cGMP) production by affecting cumulus cells through natriuretic peptide receptors. It is suggested that produced cGMP maintains the transport of oocytes via the gap junctions and leads to a continuous increase in cyclic adenosine monophosphate (cAMP) levels in the oocyte. An important role of increased internal cAMP levels in the oocyte is shown to suppress meiotic progression. Deoxyribonucleic acid studies in animals have shown that expression of the natriuretic peptide precursor increases during the periovulatory period and shows that this increase decreases rapidly after luteinizing hormone / human chorionic gonadotropin (hCG) stimulation.Human studies have shown that after ovulation induction, the CNP level in follicular fluid decreases following ovulatory dose of hCG.Polycystic ovary syndrome (PCOS) is the most common endocrine disease in the reproductive period, characterized by hyperandrogenism, oligo-anovulation, and polycystic ovarian morphology on ultrasonography, and in an animal study investigating the relationship between CNP and PCOS, serum CNP levels were increased in polycystic ovary syndrome.CNP serum level is thought to show differences between healthy women and women with polycystic ovary syndrome.
PCOS patients were treated every day, with one sachet containing 2000 mg myo-inositol, 500 mg L-tyrosine, 40 mcg chromium picolinate, 55 mcg selenium, 200 mcg folic acid. All patients underwent, before starting the therapy, after 3 months and 6 months, hormonal evaluation , hirsutism scoring and ovulation assesment. Most of them during the treatment improved their symptoms.
The investigators would like to determine how aspects of adiposity and age influence ultrasound features of the ovaries which are used to diagnose polycystic ovarian syndrome (PCOS). The study will also compare anti-Müllerian hormone (AMH) levels against ultrasound features of the ovary to predict PCOS.
General objective: To assess the preference and performance in terms of satisfaction and acceptability as well as safety profile of a novel innovative design of menstrual hygiene device (Wondaleaf®) during the night for menstruating women by comparing it to prior experience of the usual hygienic product for menstrual control, i.e. sanitary pads. Specific objectives: - To determine the preference of participants between Wondaleaf® and usual sanitary pads as a night use menstrual hygiene product. - To determine the satisfaction of participants towards Wondaleaf® and usual sanitary pads as a night use menstrual hygiene product. - To determine the acceptability of participants towards Wondaleaf® as a night use menstrual hygiene product. - To determine the safety profile of the Wondaleaf®.
Irregular menstrual cycles are common in girls for several years after their first menstrual period. The cause of abnormal menstrual cycles during this time is not well-understood. The purpose of this study is to: 1) monitor girls during a menstrual cycle (with blood and urine sampling and serial pelvic ultrasounds) to identify those girls who do not ovulate (release of an egg from the ovary), and 2) determine whether cycles can be corrected by treating girls with a short course of low-dose estrogen and progesterone.
Background: Squamous metaplasia refers to the pathological transformation of the urothelium leading to non-keratinised stratified squamous metaplasia (N-KSM). Objective: To present the investigators experiences in the diagnosis and treatment of N-KSM of the urinary bladder in children.
The purpose of this study is to study whether a drug called tamoxifen can reduce vaginal bleeding in women who are using the Etonogestrel contraceptive implant.
The study was done to evaluate the effects of the follicular and luteal phases of the menstrual cycle on sedation level at loss of consciousness and bispectral index reach to 50 during propofol anesthesia, in patients with and without preoperative intravenous dexmedetomidine .
The investigators would like to determine how aspects of metabolism and age influence ovarian function. The purpose of the study is to understand how nutrition and metabolism relate to follicle development in women with regular cycles, irregular cycles, or polycystic ovary syndrome (PCOS). We also plan to identify lifestyle factors associated with PCOS and understand how diet and activity levels impact features of PCOS.
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.
