background:   objective: the purpose of this study was to compare the predictive value of progesterone level on ivf success in women with infertility due to tubal factor or pcos.   materials and methods: in a stratified cohort study, we assigned 76 infertile women of 20-38 years old who referred to women hospital into two equal groups with fallopian tube factor infertility and pcos. we measured...

Background: There are accumulating evidences showing the role of adiponectin, a newly discovered adipocytokine secreted from adipose tissue, in the regulation of the ovarian function in dairy cows. The objective of the present study was to evaluate the pattern of serum adiponectin concentration during a normal estrous cycle in the postpartum dairy cows. Materials and Methods: Coccygeal vein blo...

background: premature luteinization during in vitro fertilization was commonly happened before the introduction of gnrh analogues. high level of unwanted progesterone is associated with adverse pregnancy outcome and is thought to be induced by inappropriate lh elevation.objective: to evaluate the progesterone level on the day of human chorionic gonadotropin (hcg) triggering in gnrh agonist and ...

BACKGROUND Improvement of neurologic outcome in progesterone-administered patients with diffuse axonal injury (DAI) has been found in a recent study. Also, there has been interest in the importance of serum parameters as predictors of outcome in traumatic brain injury. OBJECTIVES The aim of this study was to examine the effect of progesterone administration on serum levels of neuron-specific ...

Background: Tubal ligation is one of the most common contraceptive methods in the world. Some researchers believe that tubal ligation has complications. It is assumed oxidative stress can produce these complications. The aim of this study was to evaluate oxidative stress and ovarian function after tubal ligation. Materials and Methods: In this study, female rats (weighting 200-250 g) were divid...

background: the role of estrogen and progesterone in stroke is suggested in previous studies, but yet is controversial. objectives: comparing the plasma levels of estrogen and progesterone and their ratio in ischemic stroke patients and healthy population. materials and methods: this cross-sectional comparative study was conducted from march to september of 2013. sixty-six female patients older...

The effect of 6-week treatment with Ukrain at doses of 0.3, 1.5, and 3.0 mg/kg i.v. on the serum levels of steroid hormones, i.e., estradiol, testosterone, and progesterone, was studied in rabbits of both sexes. It is demonstrated that Ukrain treatment exerts minor changes in serum hormone levels. The level of estradiol was increased in the serum of male rabbits following Ukrain treatment only ...

PURPOSE To determine the sex hormone levels in the serum and aqueous humor in patients with age-related cataract and the corresponding hormone receptors in cataract lens epithelial cells (LECs). SETTING Research Laboratory, International Intraocular Implant Training Center, Tianjin Medical University, Tianjin, China. METHODS Serum and aqueous humor were drawn from patients with cataract and...

Effects of hypophysectomy or reduction of the conceptus number on luteal steroidogenesis were studied in the pregnant rat. On day 7 of pregnancy (day 1 = day of insemination), the number of conceptuses was adjusted to one by aspirating all but one conceptus from the uterus. Another group of rats received hypophysectomy on day 12 of pregnancy. On day 15 of pregnancy, the weights of the corpora l...
