The results of previous studies on the menstrual-related sleep changes were inconsistent. The menstrual-related circadian sleep-wake and rest-activity rhythms changes are still uncertain. Using actigraphic monitoring of wrist activity, we investigated the sleep-wake and rest-activity patterns of 12 normally cyclic healthy women during reproductive life. Multivariate analyses were performed duri...

A single low dose administration of a high affinity anti-progestin agent like mifepristone during the early luteal phase inhibits blastocyst implantation in human and non-human primates. Though it has been observed that luteal phase serum concentrations of estradiol and progesterone were not affected by the application of anti-nidatory dose of early luteal phase mifepristone suggesting that ova...

routinely, a bolus of 5.000-10.000 iu human chorionic gonadotropin (hcg) is usedfor the final follicular maturation and ovulation as a standard method. hcg has thesame effect of luteinizing hormone (lh) with long half-life. it has the longlutheotrophic effect which increases the risk of ovarian hyper stimulation syndrome(ohss). recently, gonadotropin-releasing hormone agonist (gnrh-a) trigger h...

The corollary follow up study carried presents variation in electrolyte content of serum during menstrual, follicular, ovulatory and luteal phases of menstrual cycle. Variation in sodium, potassium and chloride were found to be parallel with each other. Their level increase significantly from follicular to ovulatory phase and falls significantly during luteal phase. Bicarbonate levels are highe...

Pyometra is a disease that affects a large proportion of intact bitches, and typically is seen during the latter half of dioestrus. Several factors contribute to the development of pyometra, including genetic factors, an infectious component (most often Escherichia coli), and hormonal factors. Hormones may act directly on the endometrium, and also affect the immune system. In dogs, the phagocyt...

premenstrual syndromes (pms) are a group of menstrually related, chronic and cyclical disorders characterized by emotional, behavioral, and physical symptoms in the second half (luteal phase) of the menstrual cycle. several line of evidence point to a significant role of the serotonergic system in the course of the luteal phase in women with pms/ premenstrual dysphoric disorder. it has been rep...
