The objective was to examine the relationship between ovulatory follicle size and embryo and fetal survival by using circulating concentrations of bovine pregnancy associated glycoproteins (bPAG) to detect the presence of an embryo or fetus and monitor placental function. Before examining the relationship between bPAG, ovulatory follicle size, and embryo and fetal survival, the half-life of bPA...

The ovulatory LH surge induces dramatic molecular and structural changes in follicular environment, culminating with follicle rupture and release of a mature oocyte. This review addresses the pre-LH surge events associated with the ovulatory process, such as dominant follicle differentiation and acquisition of ovulatory capacity, as well as autocrine and paracrine factors induced after the LH s...

OBJECTIVE To evaluate the relation of a dietary pattern and other lifestyle practices to risk of ovulatory disorder infertility. METHODS We followed a cohort of 17,544 women without a history of infertility for 8 years as they tried to become pregnant or became pregnant. A dietary score based on factors previously related to lower ovulatory disorder infertility (higher consumption of monounsa...

The aim of the present study was to investigate nutritional and metabolic parameters during the dry and early postpartum periods of ovulatory and anovulatory cows, as well as their postpartum reproductive performance. Blood samples from 20 multiparous Holstein cows were collected once a week from the far-off dry period to 3 weeks postpartum. Early postpartum (0-3 weeks) ovulation was confirmed ...

BACKGROUND Ovulatory dysfunction is a group of disorders with variable clinical presentations occasionally having serious long-term adverse effects. It accounts for 30% of female fertility problems. Evidence suggests an association between an individual's weight and disorders of ovulation. The objective of our study was to describe the clinical and hormonal profile of subfertile women with ovul...

With extended periods of time following ovulation, the metaphase II stage oocyte experiences deterioration in quality referred to as post-ovulatory oocyte ageing. Post-ovulatory ageing occurs both in vivo and in vitro and has been associated with reduced fertilization rates, poor embryo quality, post-implantation errors and abnormalities in the offspring. Although the physiological consequences...

multiple sclerosis is a chronic inflammatory disease of central nervous system.women are more susceptible to this disease. one of the obvious clinical complaints in women with multiple sclerosis specially treated with beta interferones is menstrual cycle irregularity. the aim of this study was to determine the prevalence of menstrual irregularities and probable changes in blood levels of relate...

Background: To compare the clinical efficacy tranxamic acid and Ibuprofen in the treatment of ovulatory menorrhagia. Materials and Methods: This randomized controlled trial was performed at my office one hundred women with ovulatory hemorrhagic were randomized to take one of two treatment regimens during four consecutive cycles: tranexamic acid 3gr daily on day 1-5, ibuprofen 1200 mg daily. Res...

Treatment with non-steroidal anti-inflammatory drugs, either non-selective or selective cyclooxygenase-2 (COX-2) inhibitors, consistently impairs ovulation, indicating the essential role of COX-2/prostaglandins in the ovulatory process. Indomethacin, a potent inhibitor of both COX-1 and COX-2, induced several ovulatory alterations, consisting of a decrease in the number of oocytes effectively o...

BACKGROUND Ovulatory menstrual cycles are essential for women's fertility and needed to prevent bone loss. There is a medical/cultural expectation that clinically normal menstrual cycles are inevitably ovulatory. Currently within the general population it is unknown the proportion of regular, normal-length menstrual cycles that are ovulatory. Thus, the objective of this study was to determine t...
