Background & Aim: Electromagnetic waves can damage sex organs and cause hormonal disorders, whereas garlic is known as reducing risk factors for various diseases. The aim of this study was to investigate the probable effects of mobile phone radiation and consumption of garlic on estrogen and progesterone levels and ovarian changes. Experimental: Five groups of rats (n = 8) were used which grou...

Abstract One of the biotechnology reproductive used is estrus synchronization. This study determined body’s physiological, estradiol level, and ovarian follicle diameter in Peranakan Ongole (PO) cow synchronization using modified progesterone-PGF2α double injection PGF2α. 10 PO cows which were divided into two groups. Group 1, given a intravaginal sponge containing 250 mg progesterone/sponge fo...

LH and FSH play critical roles in mammalian reproduction by mediating steroidogenesis and gametogenesis in the gonad. Gonadal steroid hormone feedback to the hypothalamus and pituitary influences production of the gonadotropins. We previously demonstrated that progesterone differentially regulates the expression of the LH and FSH -subunits at the level of the gonadotrope: FSH transcription is i...

BACKGROUND Adrenomedullin (ADM), a novel vasorelaxant peptide, was found in human/rat ovaries. The present study investigated the interaction of ADM and endothelin-1 (ET-1) in follicles and newly formed corpora lutea (CL) and the actions of ADM on progesterone production in CL during pregnancy. METHODS The peptide and gene expression level of adrenomedullin in small antral follicles, large an...

We have reported previously that reactivation of progesterone receptor (PR) expression in estrogen receptor (ER)- and PR-negative MDA-MB-231 breast cancer cells enabled progesterone to inhibit cell growth and invasiveness, and to induce remarkable focal adhesions. The present study addressed molecular mechanisms that mediate these anticancer effects of progesterone in the PR-transfected breast ...

The clinical response of advanced endometrial adenocarcinoma to progestin therapy does not correlate perfectly with biochemically assayed progesterone receptor status of the tumor. We have previously suggested that heterogeneity of progesterone receptor at the cellular, tumor, and tissue levels, not detectable by the biochemical assay, might contribute to this discrepancy. A monoclonal antibody...

OBJECTIVE The aim of the presented study is to investigate the impact of progesterone change in the late follicular phase on the pregnancy rates of both agonist and antagonist protocols in normoresponders. STUDY DESIGN A total of 201 normoresponder patients, who underwent embryo transfer were consecutively selected. 118 patients were stimulated using a long luteal GnRH agonist protocol and 83...

LH and FSH play critical roles in mammalian reproduction by mediating steroidogenesis and gametogenesis in the gonad. Gonadal steroid hormone feedback to the hypothalamus and pituitary influences production of the gonadotropins. We previously demonstrated that progesterone differentially regulates the expression of the LH and FSH beta-subunits at the level of the gonadotrope: FSHbeta transcript...

The aim of this study was to investigate the contribution of progesterone in the development of primary varicose veins on lower limbs during pregnancy. In 50 primiparae with varicose veins, serum progesterone level was quantitatively determined in the 14th week of pregnancy and results were compared with those obtained in a control group of 25 primiparae without visible varicose veins. The mean...

The impact of a premature elevation of serum progesterone level, the day of hCG administration in patients under controlled ovarian stimulation during IVF procedure, on human endometrial receptivity is still debated. In the present study, we investigated the endometrial gene expression profile shifts during the prereceptive and receptive secretory stage in patients with normal and elevated seru...
