Authors: Kurek Eken M, Sahin Ersoy G, Yayla Abide C, Sanverdi İ, Devranoglu B, Kutlu T, Çevik Ö Abstract Polycystic ovary syndrome (PCOS) is a metabolic disorder associated with obesity and energy metabolic system disturbances in adipose tissue. Neuregulin 4 (NRG4), which is secreted by adipose tissue, regulates energy metabolism. In the present study, we aimed to evaluate the association between serum NRG4 levels in obese and normal weight PCOS patients. This cross-sectional study was conducted at a tertiary hospital in Turkey from April to August 2017. We included 148 women who were divided into four...

Conclusion In COH cycles, the ultrasonographic appearance of ovary helps to predict the number of viable embryos. In ET cycles, dexamethasone obviously improves the pregnancy rate. If the minimum P4 value before endometrial transformation cannot be kept below 0.45 ng/ml, we may consider cycle cancellation. Moreover, it is suggested that BMI of nonclassic 21-OHD women is regulated below 23.36 kg/m2.

Testis is the main organ for reproduction and boar taint in pigs; however, there have been no studies to-date on adult pig testis epigenome. The main objective of this study was to establish a genome-wide DNA methylation map of pig t...

This study was a double-blinded, randomized controlled study. Our subjects were thirty female students who were selected from the age range of 20-35 and met the Rotterdam diagnostic criteria for PCOS. The subjects were randomly assigned to two groups: fennel (study) and placebo (control). The ultrasonography assessments, body mass index, biochemical, and hirsutism variables were measured individually before and after three months usage of the fennel and placebo as our main outcome measurements. The comparison between the quantitative data obtained for the two studied groups was carried out using the Man-Whitney and chi-squ...

It is no longer considered simply as a disease of ovary. Now researchers growing awareness of the multisystem features of this disease. PCOS has a higher relationship with metabolic disturbance and hypothalamic-pituitary-ovarian axis (HPOA) function disorders. This syndrome results in hyperandrogenemia (HA), hyperinsulinemia/insulin resistance (IR), ...

Frank J. Broekmans* University Medical Center Utrecht, Utrecht, Netherlands The art of ovarian stimulation for IVF/ICSI treatment using exogenous FSH should be balanced against the relative contribution of other steps of the ART process such as the IVF-lab-phase and the Embryo-Transfer. The aim of ovarian stimulation is to obtain a certain number of oocytes, that will enable the best probability of achieving a live birth. It has been suggested that more oocytes will create a better prospect for pregnancy, but studies on the question whether the retrieval of a few oocytes less or more will make the difference are ...

Electro-acupuncture (EA) has been widely used to cure the reproductive diseases associated with endocrinological disorders. However, whether EA treatment affects HPO axis activity of physiological animals and induces alterations on the hormones in the HPO axis was also unclear. Here, we performed the EA stimuli on bil...

How can conventional dietary advice gotten it so wrong? Rather than eating plenty of “healthy whole grains,” people on the Wheat Belly lifestyle eat absolutely no grains and enjoy spectacular weight loss and reversal of hundreds of health conditions as a result. Unfortunately, many people view this as a “gluten-free” lifestyle which is incorrect. Here are 10 reasons why no bagels, pretzels, or sandwiches made from wheat flour should ever cross human lips. Gliadin-derived opioid peptides (from partial digestion to 4- and 5-amino acid long fragments) increase appetite substantially–as do related...
