background: the preparation of endometrium for embryo reception and implantation are controlled by ovarian hormones. these hormones have distinct cyclical changes during estrus cycle. objective: the aim of this study was to evaluate the changes in morphology and morphometrical indices of endometrium by daily injections of estrogen and progesterone in ovariectomized mouse. materials and methods:...

I T is generally considered that uterine motility is high during the follicular phase of the estrous cycle and relatively low during the luteal phase, although motility during the luteal phase varies somewhat among studies. In sheep, neither the variation in spontaneous uterine motility during the estrous cycle nor the effects of exogenous ovarian hormones on this motility have been studied ext...

The aim of the present study is to understand the hormonal mechanisms of the effect of malnutrition on ovarian follicle functions. For this purpose, we examined the effect of malnutrition/serum deprivation, addition of metabolic hormones and gonadotropin (IGF-I, leptin and FSH) and their combination on the release of progesterone (P4), testosterone (T), estradiol (E2) and insulin-like growth fa...

background: mellitus diabetes (dm) is the most important metabolic diseases. the incidence of dm is prone to increase. vasculopathy, retinopathy, central and peripheral neuropathy are the most important reported side effects of dm. cognitive dysfunction following dm reported in both sexes. hippocampus is a major part of brain involving in cognitive function, its cells are able to neurogenesis, ...

This article reviews an effective mathematical procedure for modeling hormonal regulation of the menstrual cycle of adult women. The procedure captures the effects of hormones secreted by several glands over multiple time scales. The specific model described here consists of 13 nonlinear, delay, differential equations with 44 parameters and correctly predicts blood levels of ovarian and pituita...

results the ovarian hormones level showed a significant difference between the experimental and control groups (p < 0.05). furthermore, the unk cell population showed a significant difference between the two groups (p < 0.05). conclusions increased ovarian hormones due to low-dose aspirin administration resulted in decline in the unk cells number, which may be effective in successful pregnancy....

This study presents a strategy for developing a mathematical model describing the concentrations of five hormones important for regulation and maintenance of the menstrual cycle. Models which correctly predict the serum levels of ovarian and pituitary hormones may assist the experimentalist by indicating directions of investigation. In addition, model simulations may be helpful for evaluating t...

in order to determine the most effective hormones on the in vitro oocyte maturation (germinal vesicle breakdown - gvbd) in a hybrid sturgeon bester, ovarian follicles were incubated at the migratory nucleus stage in the presence of several steroids, gonadotropin preparations and forskolin. occurrence of gvbd and 17,20β-dihydroxy-4-pregnen-3 -one (dhp) production were followed during an expe...
