Introduction: Tubal Sterilization (TS) is one of the most common contraceptive methods. Some researchers believe that TL has complications, whereas there are contradictory reports about TS effects on ovarian function. The aim of this study was to evaluate the indices of oxidative stress and survey ovarian function after TS. Methods: The study groups consisted of 63 Sprague Dawley female rats. T...

The cyclical changes in the gonadotropins stimulate ovarian follicular development either to the ovulatory stage or to undergo atresia. One such intrafollicular factor may be inter-cellular communication via gap junctions. We have examined the effects of two agents (retinoids and alkanols), known to disrupt or uncouple gap junction, on FSH-stimulated LH receptor induction and progestrone synthe...

Statement of Problem: Epulides Fissurata (EF) are common proliferative and denture- induced lesions of the oral cavity with a predilection for female. This suggests a possible role for sex steroid hormones in the development and progression of these lesions. Purpose: The objective of this study was the immunohistochemical evaluation of epulis fissuratum of the oral cavity for estrogen and proge...

Background: Effect of drugs on different receptors may cause effect and also unexpected side effects.  For example, using Dopamine as an anti-parkinson drug block the upper GnRH axis and thatchr('39')s why some sexual disorders happen. In this study, the effect of serotonin as Fluvoxamine injection on lower levels of GnRH by blocking the upper GnRH axis with injection of Bromocriptine was inves...

Purpose: The aim of this study to investigate the effect of progestrone and calcium ionophore (A23187) on mouse sperm parameters and fertilization rate. Materials and Methods: Csauda epididymidis were then obtained from NMRI male mice (10-12 wk old) and were divided to three groups: Control, adding progesterone (10µg/ml) and addingionophore (10mM) After sperm were prepared and incuhated in T6 ...

To evaluate the effectiveness of conjugated estrogen (Premarin) and progesterone in twenty-one postmenopausal women who had been menopause one year, we tested during a 6-month period the serum lipoprotein levels in subjects who offered by premarin in dosage of 0.625 milligram for days 1 to 25 and oral medroxy progestrone acetste for days 15 to 25 of a 30-day cycle. Twenty-one subjects completed...
