‘Ovulatory dysfunction’ bears the imprimatur of a succinct medical diagnosis, but what does it really mean and above all, how do you diagnose it, especially in women with a normal menstrual history? Although we have multiple measures in our modern toolbox: ultrasound for daily follicular monitoring, hormonal assays of serum, urine and saliva (some for instance LH available over the counter to o...

Twenty-two Serrana goats were studied through two successive estrous cycles in order to characterize their follicular dynamics during the breeding season. The ovaries of the goats were scanned daily by real-time ultrasonography and all follicles >or=3mm were measured and classified. The data were classified by the number of follicular waves per goat to test the hypothesis that temporal and morp...

BACKGROUND Polycystic ovary syndrome (PCOS) is a common condition in women of reproductive age with well established metabolic abnormalities. There are numerous diagnostic criteria generating several reproductive diagnostic phenotypes [National Institute of Health (NIH) hyperandrogenic anovulatory PCOS and non-NIH PCOS including hyperandrogenic ovulatory or non-hyperandrogenic anovulatory PCOS]...

Follicle growth and associated changes in circulating hormone concentrations were evaluated after follicle ablation in mares (n = 13) during four 13 day periods beginning at means of -98.5, -61.4, -26.0 and 10 days from the first ovulation and corresponding to mid-anovulatory, early-transitional, late-transitional and ovulatory periods, respectively. During each period, all follicles > 5 mm in ...

Polycystic ovary syndrome (PCOS) is a complex hormonal disorder which impairs ovarian function. The adherence to healthy dietary patterns and physical exercise are the first line of recommended treatment for PCOS patients, but it yet unclear what type diet more adequate. In this case-control study, we explored associations between five quality indices presence PCOS. We enrolled 126 cases 159 co...

Нарушения овуляции являются распространенными причинами аменореи, аномальных маточных кровотечений и бесплодия, а также частыми проявлениями синдрома поликистозных яичников (СПЯ). Известно о наличии многих потенциальных причин факторов развития овуляторной дисфункции, которая является сложной проблемой для начинающих опытных врачей, преподавателей тех, кто проводит фундаментальные, тр...

The objectives of this research were to partition variation in ovulatory follicle size into genetic and nongenetic components and to assess the utility of ovulatory follicle size as an indicator trait associated with reproductive success in beef cattle. Data were collected during the years 2002 to 2005 from 780 beef females that ranged in age from 1 to 12 yr (mean of 2.4 observations per female...
