the present study was conducted to see the effect of non-specific genital infections and ovulatory disturbances on clinical signs of oestrusnamely oestrus duration, tonicity of uterus, relaxation of cervix and persistence of follicle. the mean values of oestrus duration, tonicity of uterus and relaxation of cervix varied significantly (p

Subclinical ovulatory disturbances (anovulation or short luteal phases within normal-length menstrual cycles) indicate lower progesterone-to-estrogen levels. Given that progesterone plays a bone formation role, subclinical ovulatory disturbances may be associated with bone loss or less than expected bone gain. Our purpose was to perform a meta-analysis of prospective studies in healthy premenop...

Women experience acute myocardial infarctions (AMI) 10 years later than men – evidence that estrogen is protective is not consistent. Ovulatory disturbances (low progesterone but normal estradiol levels) silently occur in >33% of all cycles. Progesterone-based (cycle-timed serum or saliva) levels or urinary metabolite excretions are necessary to diagnose silent ovulatory disturbances within reg...

We have been asking, through a series of newsletters, what we know about women’s health related to normal progesterone levels and ovulation. We have discussed the fact that ovulatory disturbances (meaning anovulation and short luteal phase cycles) are common and hidden within menstrual cycles that seem perfectly normal. I speculate that at least a third of all cycles in regularly menstruating, ...

Learning Objectives: 1. Perimenopause, although characterized as a time of dropping estradiol, involves chaotic estrogen levels that average >20% higher and intermittently are extremely high and ovulatory disturbances with decreasing progesterone levels. 2. Perimenopause begins and is most symptomatic when cycles remain regular. 3. Perimenopause is highly symptomatic for more than 20% of women—...

Recent research has not been able to demonstrate close endometrial morphological correlations with specific abnormalities of menstrual bleeding, but has pointed to an increasing number of molecular mechanisms that may be involved in the occurrence of certain forms of abnormal uterine bleeding. Ovulatory and anovulatory dysfunctional uterine bleeding (DUB) and progestogen-related breakthrough bl...

Polycystic Ovary Syndrome (PCOS) is characterized by ovulatory disturbances, hyperandrogenaemia and hyperinsulinemia secondary to increased insulin resistance. In PCOS, hyperinsulinemic insulin resistance is of interest because skeletal muscle may be resistant to insulin in terms of glucose metabolism, while the ovaries remain sensitive to insulin with regard to stimulation of testosterone bios...

Sex hormones may contribute to inter- and intra-individual differences in pain by influencing emotional modulation of pain and nociception. To study this, a well-validated picture-viewing paradigm was used to assess emotional modulation of pain and the nociceptive flexion reflex (NFR; physiologic measure of nociception) during mid-follicular, ovulatory, and late-luteal phases of the menstrual c...
